Smoking vs. Vaping

The practice of tobacco smoking use has been around as early as 5000-3000 BCE. Native Americans and other ancient cultures harvested the plant and then smoked it for medicinal and ceremonial purposes. Yet as discussed in class, it was not until the late 1950’s that humans began to realize it’s harmful and dangerous side effects. On the other hand, vaping is a relatively new idea (with the first electronic cigarette being developed in 2003) that has been argued by some to be a safer alternative to smoking. While others debate the new substitute to be just as bad, if not worse, than traditional smoking. So, who is right?

When smoking the heat from the fire causes the tobacco to go from it’s solid state to vapor. In cigarette’s this releases nicotine which gets absorbed into your bloodstream through the lungs and in result causes constricted blood vessels, increased heart rate, feelings of alertness, and the release of dopamine in your brain. However, since nicotine is a stimulate, once it is no

longer available you “crash” and begin to crave more, which in the long run could cause addiction. Being addicted to anything isn’t good, especially something so harmful like tobacco. From the extensive research that has been done on tobacco use, it is common knowledge that smoking not only causes addiction, but can create cancer causing effects, development of tar in your lungs, blackening of your teeth, and destruction of taste buds. This certainly magnifies the cons of cigarette smoking. According to the American Lung Association smoking kills approximately 443,000 Americans each year. To a reasonable person the side-efffetcs of smoking should appear not only very dangerous, but also extremely harmful.

Now what about vaping? Electronic cigarette’s transport a nicotine-containg aerosol (vapor) by heating a solution containing nicotine, glycerol, and sometimes flavoring agents. Theoretically this results in the same effects as smoking, without the process of inhaling the dangerous smoke entering your lungs. The amount of nicotine in the solution (e-liquid) can be regulated and may range from 0-30µg of nicotine per puff. This way users can chose not only the flavors and brands of their product, but also the strength. A study conducted by the Society for Research of Nicotine and Tobacco on popular e-cig brands determined that the level of nicotine spawned from 15-20 puffs varied from 0.5µg to 15.4µg. They concluded that the amount inhaled from 15 puffs is much lower compared to one puff from smoking a traditional cigarette. This could leadus to believe that e-cigarette’s are in fact a safer alternative and could help wean users off a smoking habit. On the contrary, the contents of the e-liquid found in this alternative can widely vary from company to company and are sometimes mislabeled. In addition e-liquids contain a base that helps contain moisture without causing sogginess. This base is found in cosmetics and theatrical smoke, that have been known to cause eye irritation and respiratory infections. Scientists are yet to determine prolonged effects of exposure to this base and therefore the FDA has been able to easily approve these products. To me it seems logical that smoking something that’s used in theatrical smoke may not be so good for you. Another argument against vaporizers is that the wide variety of flavors can cause the product to become more appealing to younger people. With delicious names such as Blueberry Cheesecake or Sweet Tangy Melon, I can see how the product could easily attract a younger crowd.

So which option is safer? By examining all the evidence it is hard to say. Since smoking has been around for so long, all the information we have is from prolonged studies and can be much more heavily relied on. With vaping being relatively new we simply don’t have access to longitudinal studies and therefore cannot draw a clear conclusion on what is worse. The gray area in e-cigarette’s and similar products is way too foggy to say that vaporizers are a better option, and if anything could support the fact that they’re are just as bad or even worse than traditional smoking.  But for the sake your own health, maybe you should put both products aside and wait for scientists to determine the true dangers of vaping.

 

 

It’s for my Glaucoma bro…

glocky

With the emergence of medical marijuana in the nation over the past decade, the rare eye condition, Glaucoma, has become a household name of sorts. What was once a condition rarely referenced outside of ophthalmologist’s offices, is now splattered across the news, pop culture, and almost every stoner comedy. But for those who suffer from this disease, it is no laughing matter. Glaucoma effects over 3 million Americans today, and is the second leading cause of blindness in the world according to the World Health Organization. But thanks to the medical marijuana movement, the situation for Glaucoma patients is looking up!

As of now, Glaucoma has NO cure. Those affected with it, even those who receive treatment, have a ten percent chance of losing their vision. Glaucoma is a condition in which the optic nerve deteriorates over time. This is caused by higher than normal levels of Intraocular Pressure. Those who suffer from glaucoma regularly experience peripheral vision loss as well as extreme pain caused by this internal pressure differential. So how does cannabis factor into all this?

eyez

Cannabis has an uncanny ability to relieve ocular pressure. What many people note as red eyes in cannabis users, is actually the manifestation of Interocular Pressure relief. That’s right! When glaucoma patients ingest marijuana and their eyes begin to redden, they are actually being relieved of their Interocular Pressure and the pains associated with Glaucoma. Unfortunately, due to the limited amount of research available on medical marijuana it is unclear of the future of its use as medicine for Glaucoma patients. Although, it has been proven to relieve pressure and therefore prevent damage to the optic nerve, scientists fear its blood thinning affects might contradict these benefits. That being said, in the thirty years of limited testing that has been conducted, damage to the optic nerve has not been noted. Patients praise marijuana for its alleviative affects, and simplicity. Many patients have reported liver and kidney damage as a result of the numerous glaucoma medications they are prescribed. Elvy Mussika, a medical marijuana patient for over 30 years had the following to say on the matter,

“I was diagnosed with Glaucoma in 1975. Within a year, I already knew that there was nothing absolutely nothing that was on the market then worked for my glaucoma except for marijuana… One of the benefits of using marijuana is that most of us drop all the other drugs that really do a number on our heads and make it difficult for us to stay healthy..”

Patients seem to be very open and accepting of cannabis as a treatment options, but doctors are much more skeptical. Doctors worry that having to be in a state of perpetual “high” is dangerous and ineffective as a treatment.  The American Glaucoma Society, takes a conservative approach, as well

“[T]he mainstay of treatment for glaucoma patients is lowering the IOP [intraocular pressure]… Although marijuana can lower the intraocular pressure (IOP), its side effects and short duration of action, coupled with a lack of evidence that it use alters the course of glaucoma, preclude recommending this drug in any form for the treatment of glaucoma at the present time.”

Despite the skepticism, marijuana advocates and patients maintain high hopes for the future of cannabis as glaucoma treatment. With new advances in the medical marijuana field, it will soon be possible to dose out cannabanoids in a regular and moderate dosage throughout the day. Similar to the way in which some diabetic patients receive insulin regularly throughout the day without the pain of injections. Regardless, patients rejoice that there is a cheap, non-addictive, and non-invasive medication to alleviate their pressure differentials available today. With only 30% of Americans even having knowledge of this condition, maybe it is good that Glaucoma is receiving the national attention it is. That being said, it is important to remember that marijuana is not just for recreational use, it has marvelous medical benefits for many people. Whether it be Epilepsy, Glaucoma, Multiple Sclerosis, or Cancer patients across the country depend on its use. However, for many patients across the globe, the use of marijuana carries heavy consequences. Even here, the U.S has maintained its federal classification of marijuana as a schedule 1 drug. Deeming it void of medical use and having a high potential for abuse.

In conclusion, marijuana has shown a fascinating ability to relieve the main proponent of optical nerve damage, Interocular Pressure. This provides relief and resistance to the escalation of the Glaucoma disease in many patients. Whether marijuana will eventually cure Glaucoma is unknown, but as states begin to initiate their medical programs, more information is being learned every day. Scientists and doctors are skeptical, but patients and proponents praise the drug, and pray for continued investigation and investment.

Do Video Games Make you a Better Driver?

Driving is one of the, if not the most, dangerous activities that the vast majority of society engages in on a daily bases. In this day in age there are many different methods in which entities try and protect society to the best of there abilities in order to make driving as safe as possible. With this in mind, I was compelled to conduct research on a way that was rumored to improve you driving skills. I have heard that certain types of video games, particularly ones involving driving, improve you ability to drive.

Shortly into my research I found an article titled, “Do video games really make you a better driver?” that discusses the reasoning behind why video games make you a better driver. The article starts off by saying that video games are in fact good for your brain, and then goes on to say that they improve your ability to make the right decision faster. The article then goes on to explain a study conducted on two groups 18-25 years old, the one group played fast paced action video games while the other group played slow paced video games. The study examined individuals from both groups ability to make quick decisions and answer questions. The researchers found that the group that played fast pace video games was able to make decisions and answer questions at a 25 percent faster rate. Not only were they able to make these decisions at a faster rate, but also these decisions were accurate, which is the crucial factor as to why video games benefits driving. My only criticism on the study is that the connection to driving is present, logical, and easy to follow; however, the study would be more meaningful if they did a test involving driving. They could do some type of simulation where each individual experienced the same potentially dangerous situations while driving and examined how they the two groups reacted differently.

In order to ensure that this study was not an outlier I conducted further research to see if similar studies drew similar conclusions. The next study I found was explained in an article titled, “Increasing Speed of Processing With Action Video Games”. This study simply reviewed evidence that found that individuals playing action video games significantly reduced their reaction time without loosing accuracy. Unfortunately, this study did not test the individual’s improvement driving capabilities; therefore, I continued to look for ones that did.

Eventually I was able to find a study that actually conduced an experiment that tested driving through a simulator. The study was discussed in the article, “Excellent gamer, excellent driver? The impact of adolescents’ video game playing on driving behavior: A two-wave panel study”. The study included 354 adolescents that played video games took a driving stimulator. The researchers found that they did have improved reaction time, which benefited driving; however, they exhibited risky behavior while driving, which in fact made them worse drivers. The conclusion of this study was unique in that it said that video games made them worse drivers; however, I wonder if they took greater risks because they knew they actually were not in danger since it was a simulation.

Take home message: Action and high paced video games improve reaction time in individuals, thus, giving them the an asset to become a better drivers. It is important to realize that video games only give the individuals an asset to become better drivers, but does not mean that they will be better drivers.

Can you control your dreams?

Have you ever had a really good dream?  One you wish you could dream all over again?  I always wished I could control my dreams, maybe bring me back to a really good one.  I wondered if it was possible, so I decided to do some research.

52722a498355eDeirdre Barrett is the author of “The Committee of Sleep: How Artists, Scientists and Athletes Use Dreams for Creative Problem-Solving-and How You Can, Too” and did an interview with the Scientific American on dreams.  She described the scientific definition of a dream as a “narrative experience that occurs during sleep” (Barrett).  She was then asked if it is possible to control our dreams, where she said that yes it is possible.  She said it depends on what type of dream: lucid, nightmare, etc.  To solve a problem in a dream, one must think of that particular problem before they go to sleep.  One could also place something next to their bed that would help remind them of the problem, such as a person he/she is in a fight with.  Also important, when one wakes up, they mustn’t get right out of bed.  They must lay for a second, and the dream will come back to them.  Another interesting thing Barrett spoke about was if someone wants to dream of a particular person or experience.  You have to get a picture of who you want to dream about, or a specific line they would say (anything relating to them) or the experience you had.

Controlling lucid dreams take a very different approach.  Lucid dreams in general are risky, and much harder to control.  Lucid dreams occur during your REM stage, when you are actually aware that you are dreaming.  Since you are aware that you are dreaming, you then might try to control your dream.  It is a lot harder to control this because you are
still sleeping, and these dreams can get a
little out of control sometimes.

The video below tells of how you can control your dreams:

http://https://www.youtube.com/watch?v=l18FvtFl7ks

 

Here are some more ways to control your dreams from Yahoo Health:

1.Write down your dreams in the morning.  That way, you will eventually recognize patterns in them.  

2. Pay more attention to your daily activities.  You have to understand your life.

3. Get a habit.  Something to do everyday and get the hang of.

So now that we know how to control dreams in general, let’s get in a little more in depth.  Ever wanted to have a flying dream?  Well, since flying is not something humans normally do, your body is going to have to grow on it.  So jump around in your dream, higher and higher, and eventually you will fly.  What about changing the scenery?  Visualize where you want to go.  Whether it is Greece on the other side of the door, or look into a mirror and see a shopping mall.  As long as you believe that destination is truly there, you will be taken there.  Traveling through time can be made easy with a time travel machine you think up or fly into the clouds and end up in a different time period.  To find objects you want, just reach inside your pockets, bags, in front of you; it is guaranteed to be in one of those places considering your mind is controlling it.  Last but not least, if you want to talk to your unconscious self, it would be much easier to put yourself into a dog or cat form, and then talk to that animal as yourself.  It sounds crazy but hey, it works!

Although more research must be done on controlling dreams, we now know it is possible, no matter how crazy it seems.  Just put in a little effort next time you sleep, and you never know, you could be controlling your dreams in no time!  Sleep tight!

Different Sleeping Positions

Considering that we spend approximately 33% of our lives sleeping, the position in which we sleep must be important. I have a tendency to sleep on my stomach and often wake up with mild back pain. I feel strain on my lower back when I lay in this position, so I wanted to look into what sleeping positions are good and what sleeping positions are bad to avoid any possible physical pain in the future.

After doing research, I have concluded that sleeping on your back does damage to both your lower back and your neck. Having to turn your head to the side on your pillow causes unnecessary strain on your neck. If you can only sleep on your stomach, it is recommended that you use a soft pillow or no pillow at all in order to avoid putting your neck at an awkward angle. In general, you should avoid sleeping on your back if you are able to sleep in other positions.

In addition to sleeping on your stomach, sleeping on your back can also cause lower back pain. To avoid this back pain, it is recommended you put a pillow below your knees in order to elevate your lower body and facilitate the natural curve of the spine. Sleeping on your back can also cause sleep apnea which is when you periodically stop breathing in your sleep. This causes your sleep to be less sound and restful. On the other hand, I consulted with medicaldaily.com who said that sleeping on your back  is the healthiest position. There reasoning is that your head, neck, and spine are all aligned when you sleep flat on your back which results in the least amount of pressure added to your lower back and neck.

The final position which is recommended by bettersleep.org is sleeping on your side.  If you put a pillow in between your legs, it helps diminish lower back and hip pain. Medicaldaily.com ranked sleeping on your side as the second healthiest position to sleep in. Just like sleeping on your back, sleeping on your side does help with pain in the lower back and neck. Unlike sleeping on your back, sleeping on your side also helps to prevent sleep apnea. That being said, there are negatives to sleeping on your side such as wrinkling of the skin. As a matter of fact, sleeping on your left side versus sleeping on your right side can cause a number of different issues. If you sleep on your left side, you can damage internal organs such as your liver, lungs, and stomach. If you sleep on your right side, you can increase heartburn. The positive to sleeping on your left side is it helps limit acid reflux and promotes better blood flow which is why doctors advise pregnant women to sleep on their left side.

It does not seem that there is a consensus as to which sleeping position is the best. Some doctors believe sleeping on your back is the best method for your back and neck while others believe sleeping on your side is the best way to avoid physical pain while preventing sleep apnea from taking place. Either way is an effective method for sleep as long as you do not position your limbs in an uncomfortable and unnatural way. One thing that is certain is that sleeping on your back is an unhealthy and ineffective way to sleep.

What can our eyes tell us?

Stock_07_by_absense_stock

Most people say that the first thing they notice about an individual is their eyes.  However, besides just looks, can eyes tell us anything important about a person? Actually, your eyes can tell you more about yourself than you may have previously thought. It has been proven that an individual’s eyes can give insight on their health or the way in which their body functions. The color of a person’s irises and sclera can often alert a person if they have certain health issues.

There are many different health related associations with blue or light colored eyes. The first is that people with blue eyes tend to be more light-sensitive. It likely due to the fact that light-colored eyes have less light-absorbing eye pigment. Darker eyes aren’t as light sensitive because they have more pigment, meaning less light gets through the iris. Another association is that blue or light- colored eyes may be more at risk for cancer. Due to the fact that “lighter eyes have less pigment to protect them from harmful ultraviolet rays, it’s true that light-eyed people have a greater lifetime risk for melanoma of the uvea, the middle layer of the eye, than their dark-eyed peers” (Vann). Although this form of cancer is extremely rare, it is still possible due to the eye color. The last important association is an autoimmune disease that causes blotchy skin color, called Vitiligo, is less common is lighter eyes. In one large study, nearly half the patients with this disease had brown eyes. Researcher realized that “two particular genes, TYR and OCA2, which play a role in blue eye color, also decrease risk for vitiligo” (Klein). Which could be why individuals with blue or light eyes are less likely to get this disease.

Brown eyes also have a health association. Individuals with brown eyes are at a greater risk of getting cataracts. A study done by the American Journal of Ophthalmology in 2000 found “dark-eyed people had a 1.5 to 2.5 times greater risk of cataracts.” (Klein). Some researchers believe this may be due to dark eyes being more light-absorbent which increases the temperature of the lens.

There are also health associations with what the white a person’s eye, called the Sclera, looks like. The first is that if it begins to turn red, it may mean the person is suffering from an infection, allergies, or dryness. Yellowing of the eyes may mean the person has a problem with their liver. Lastly a white or grey ring forming around the iris, a condition called Arcus Senilis, is a result of cholesterol deposits. This shows the person may have high cholesterol, meaning they are at a higher risk for a heart attack or stroke.

Overall, it is clear our eyes have more purpose than just sight alone. An individual’s eyes can tell more about them than most would imagine. Studies have proven and scientists strongly support the claim that individual’s eyes can give insight on their health or the way in which their body functions.

Cell Phone Radiation: Dangerous or Not?

http://blog.sfgate.com/techchron/files/2012/03/1233511701.jpg

http://blog.sfgate.com/techchron/files/2012/03/1233511701.jpg

I know that many people have posted about this topic throughout the semester, but I think that it is a topic worth addressing again. Cell phones are ubiquitous in our society. Everybody them and everybody uses them. Approximately 6 billion people on this planet have access to a mobile phone. But is this mainstream device dangerous? Yes, they provide convenience and entertainment but is the use of a cell phone really worth the risk that it carries?

Cellular devices use “electromagnetic radiation in the microwave range.” This is similar tot he type of radiation produced by other digital wireless systems. In 2011, the International Agency for Research on Cancer classified cell phone radiation as Group 2B. This means that cell phone radiation is possibly carcinogenic. Some agents and mixtures also classified as Group 2B are acetamide, lead, uracil mustard, and cobalt. The agents and mixtures included in Group 2B usually have limited or inadequate evidence of carcinogenicity but relevant data proves a slim chance of carcinogenicity.

So what does this mean for cell phone users? Group 2B is a lot better than Group 2A (meaning probably carcinogenic) and Group 1 (carcinogenic). In order to truly tell if cell phone radiation is carcinogenic or not, long-term research must be conducted. However, scientists have begun conducting studies to try and understand the connection between cell phone use and cancer.

A scientist with the last name of Yakymenko conducted a meta-study. From his meta-analysis of epidemiological and experimental data, Yakymenko concluded that the exposure long term low intensity microwaves can lead to tumorigenesis. Yakymenko analyzed several studies that dealt with “radar radiation and cancer promotion,” “rodent model of cancer promotions by microwaves,” “microwaves and cell metabolism,” and “microwaves of radars and mobile communication systems.” Based on these conclusions, Yakymenko suggests that precautionary measures for everyday microwave exposure from cellular devices should be put into place. Despite the relatively low risk of brain cancer, people should still be cautious because ailments can take up to 30 years to fully develop. After reading through his study review fully, I believe in these results. However, I still must remain hesitant to believe it 100% because of the file drawer problem. Since this is a meta-study, it could suffer from the file drawer problem. Studies that found that cellular radiation had no affect on cancer formation could not have been published. Therefore, the results of those null-hypothesis studies would not be considered in Yakymenko’s analysis.

It is unrealistic to tell the world to stop using cell phones. However, it is important that the world is aware of the dangers we may face because of cell phone radiation. The World Health Organization recommends that people try to adopt hands-free devices or texting to reduce the radiation exposure. Obviously, the exposure is higher when the cell phone is closer to our heads and bodies. It is also best to try and keep mobile phone use limited for children.

But despite all of this, there have been many studies that concluded that cell phones do not cause cancer. In 2010, the largest international study of brain tumor wish in mobile device usage was conducted. The Interphone study group conducted an “interview-based case control study” with over 4,00 glioma and meningioma patients. In the end, the Interphone study group saw no increase in risk of meningioma or glioma due to the use of mobile phones. However, the long-term effects still need to be investigated.

So what does all of this mean? Are cell phones good or bad? Well, I believe that it is still too early to tell. Cell phones have only been around for about twenty years. Only time will tell if the cell phone radiation will effect the world in the long term. To really find out what is going on, a study should be conducted now that follows thousands of people, with controls, throughout their lifetimes. For now, I would use my cell phone with caution, but there is no way that I am taking it out of my life.

Do Your Outfits Affect Your Grades?

 

7When I wake up in the morning before class or before I head to an exam, I usually do not think twice before I throw on a pair of sweat pants and sweat shirt. But could what I wear affect how I perform in the classroom? Does dressing more comfortable affect how I preform, or could it be wearing an outfit that is nicer can do so?

In a unique study I came across the scientists conducted an experiment putting this to the test through lab coats. Within in this single study two different experiments were conducted. First, fifty-eight undergraduate students (19 male, 41 female) were randomly assigned to two groups, one group wore a lab coat and one that wore there own clothing. To create blindness, the subjects wearing lab coats were told all prior subjects wore them as well. Both groups then completed a test that measured the time it took to indicate whether the letters on the screen or red or blue and their accuracy in doing so. The time did not vary between the two groups, but the group that wore lab coats had nearly half the amount of errors as the other group.

 

The second test divided seventy-four new undergraduate students into two groups. This time both groups were given lab coats. One group was told that the coat they were given was a doctor’s coat and the other group was told the lab coat was a painter’s coat. The people were then surveyed on what they thought of the coat. By doing so, they were able to make a third group based off the people who thought it was a lab coat described as a doctor’s coat. In this test each subject was shown two sets of two pictures. When each set was shown, two of the same pictures were shown on the screen, but each had four minor differences, and they were all instructed to write down the differences they found as quickly as possible. Then, it was measured the time it took and number of differences that were found. The results showed on average, those wearing “a doctor’s coat” found more differences than those who wore the “painter’s coat” and those who saw it as a lab coat not a painter’s coat. The time it took the three groups was relatively similar. This study can lead one to conclude that by wearing the doctor’s coat, one may become more attentive than if they were wearing a regular lab coat or a painter’s coat.

 

Multiple studies have shown that a person who is wearing formal attire will have an increased “abstract cognitive processing.” ttp://spp.sagepub.com/content/6/6/661 These studies show that in a way, formal clothes make us feel powerful, giving a person an increased level of confidence they did not have before. Based off the two studies I have concluded to fail to reject the hypothesis that the clothing you wearing can affect how a student performs in the classroom. The studies show that some clothing more than others can make a student more likely to pay closer attention to detail.

Personality Differences Between Dog and Cat People

         Cats or Dogs? I am sure we’ve all been asked the age old question one too many times. The cliche question is commonly posed in icebreaker activities, sparking an interesting discussion into the reasoning behind people’s preferences. Interestingly enough, the question seems to result in a one sided answer, with most people preferring one over the other.  The Humane Society of the US reports that 65% of American households own a cat or dog. With that being said, it’s no surprise that many Americans today either distinguish themselves as a “cat” or “dog” person. The label may be derived from childhood experiences, current or past pet ownership, or simply a self proclaimed title constructed by the media or a friends experience with these pets. According to a poll conducted by the associated press, 74% of participants claimed to favor dogs more, while only 41% felt passionately about cats. Notably, there have been multiple scientific studies examining the differences in personality and physical appearances between cat and dog lovers.

         In a web based study  published by Sam Gosling, a psychologist at the University of Texas, 4,565 participants were initially asked if they identify themselves as a cat or dog person, neither, or both. They were then asked to complete a 44 question assessment that sought to examine the “Big Five” personality dimensions that psychologists use to study human personalities. These broad personality domains include extraversion, conscientiousness, agreeableness, neuroticism, and openness to experience.

It was found that on average, dog lovers were 15% more extroverted and 13% more agreeable. These statistics coincide with the fact that dogs are naturally more sociable and “people person” oriented than cats are. Additionally, those who favor dogs tested 11% more conscientious (being able to display self discipline and aim for personal achievement) than cat lovers. This can probably be accredited to the fact that dogs are more easily taught commands and tasks than cats are.

        Cat people tested much differently on the personality scale, they were found to be 12% more neurotic, meaning they are emotionally unstable. On the other hand, cat people were 11% more open than dog people, meaning they hold a greater appreciation for worldly concepts such as art and emotion, and possess a stronger sense of imagination than their counterpart. These people were likely to hold unconventional and unusual beliefs, straying from traditional, cliche interests.

        Overall, dog owners were found to be more social and accepting than cat owners, who tend to be introverted and keep to themselves. Interestingly enough, Sam Gosling, a psychologist at the University of Texas in Austin and  head researcher in this study, has come to illustrate the major differences in cat and dog owners in a single comparison. Gosling asked pet owners, “If you had adequate living space and there were no objections from other people in your life, and someone gave you a puppy as a gift, would you keep it?” The responses of cat and dog people were analyzed, and it was found that two thirds of exclusive cat owners said they would not accept the gift, while 70% of dog owners said they would welcome a cat into their household.

         Personally, I am not surprised by these statistics. It’s understandable that dog owners, who were in general found to be more agreeable and easy going, would accept a cat into their household. On the other hand, cat owners would be hesitant to welcome a rowdy dog into their house due to their more introverted and sedated personality traits.

         Multiple studies have been conducted that attempt to uncover the personality differences between cat and dog owners, and findings have been similar across the board. Another article I stumbled upon talked about a study conducted of 600 college aged students.  Similar to the  initial study I analyzed, dog owners were found to be more lively, seek companionship, possess a more dominant personality, and distinguish themselves as “people persons.” On the contrary, cat owners were found to be smart, open minded, seek affection, and prefer solitude.

         Who would have thought that one’s choice in household pet could say so much about their personality? Overall, it can be agreed upon that personality traits can be partially determined through an individual’s affinity to either a cat or dog.

 

    

What Makes Waves?

Some are small. Some are tall. Some lap at our feet. Some knock us over. Some destroy entire cities…towns…islands…and cultures. If we’ve ever seen the ocean-or any other relatively large body of water- we’ve seen wave as well. We see all different kinds, with all different velocities and looks and heights. And oftentimes, we’re more inclined to play in or surf them, rather than ask ourselves…what makes waves? What even are waves?

            In high school physics class, most of us learned about energy (or definitely should have, at least). When we learned about energy, we learned that it moves in waves. All energy possessed different wavelengths, with different heights or crests, but regardless, we learned that all energy moves in this pattern of a wave.

300px-Standing_wave

            Energy is everywhere. It’s in the air, on the ground, in the plants, the animals, ourselves, and anything around us. It’s constantly moving. This holds true to water in the ocean. Given that the Earth is made up of 71% water, whether it be in oceans or lakes, it’s only logical that this constantly moving energy must logically move through the seas as well.

Flat-Ocean

So it does, and we see it through this perfectly visible medium that is ocean water. Regarding this type of water though, out in the ocean, the waves aren’t typically, actually moving anything- the water remains relatively stationary. What is seen then isn’t necessarily the water moving…but rather, the energy moving. So where does this energy even come from?

Most of the time, it simply originates from the wind. As this wind blows, it collaterally disturbs the surface of the water. And as it continues to blow, more friction is manifested, more continual disturbance is created, and the wave crests continue to rise and rise until the water is higher and waves are effectively created. These types of ocean waves, transferring energy along the water’s surface, is inherently known as surface waves, or wind-driven waves.

            However, as we’ve all probably heard at some point in our lives, the gravitational pull of the moon and the sun cause waves as well. These waves, caused by this gravitational pull and the rotation of the Earth, are generally refereed to as tidal waves.

            With all of this information combined, it only makes sense that tsunamis (which are, despite common belief, not the same as tidal waves) are the same as this typically transferring energy. However, when something such as a landslide or an earthquake contributes an unexpected mass amount of energy to the ocean water, it largely contributes to the waves that are already moving, therefore…simply…creating one massive wave.

image003

What causes waves to break along the shore though? Well, this energy wave does not only move along the surface of the water. It also moves along the ocean bottom. As the sea gets shallower and shallower toward the shore, “the drag on the wave’s bottom becomes stronger”, and in turn, “the upper part of the wave begins to tilt forward,” as it continues to move at its regular, faster speed. And therefore, the wave as we know it, and the wave as we enjoy it, is created.

As for those waves that are so common to Beaver Stadium? They’re instigated by energy as well- however, it’s main source is often reported to be the pride of Nittany Nation.

Weight Lifting or Calisthenics

For men my age, one of the more common forms of exercising is weight lifting. There are numerous forms of exercising, but one of the biggest debates is whether calisthenics or weight lifting is better for your body. Both weight lifting and calisthenics have pros and cons that the other does not have, but which of the two exercises is the best?

Weight lifting is exactly what its name says it is, lifting weights or using resistance equipment. It is mainly done to build muscle or mass, but following the right workout routine, can be used to lose weight. Calisthenics has become increasingly popular over the past twenty years. It involves exercises that do not require extra weight to be added, therefore can be considered as body
weight training. Well known calisthenics exercises include push-ups and pull-ups.

A test was conducted to see the results of weightlifting on elderly men and the subjects were fourteen 60-70 years old. None of the subjects has any prior experience in weight lifting. The study was conducted by performing exercises to train elbow flexers on one arm. This lowers thearnold-blueprint-mass-training-3-graphicsoverall need of a control group because they’re other arm acts as this. Different exercises were performed three days a week over the course of twelve weeks. After the twelve weeks were over, the maximum repetitions able to be completed increased in all the subjects. The twitch torque was recorded at elbow joint angles, and it increased considerably in the arm that experienced training, but did not increase at all in the arm that did not experience the weight lifting training.

Calisthenics research was conducted on a group of Army ROTC cadets. Each cadet received multiple baseline tests on their current physical state including height, weight, overall fitness level, cardiovascular response to exercises, and Army physical fitness test. The 2work-out6 cadets completed calisthenic training three days a week for four weeks. Following the four weeks of calisthenics training there was not enough evidence to fail to reject the hypothesis that calisthenics improves overall fitness levels. There are many factors that may have affected this. One being that ROTC cadets already face intense military training, and the calisthenics may not have been as intense as the training they already receive. Also there was no way to prevent a bias. The cadets may have not taken it seriously and may have not worked as hard as their bodies would allow them too. With the great deal of variables that were not accounted for in this study, it is difficult to use this as an accurate representation of the benefits of calist
henics.

Another study analyzed the affects of calisthenics on obese children. They performed six different calisthenics exercises three times a week and this study showed that over the course of six months the average child dropped from 45% overweight to 25% overweight.

Both calisthenics and weight lifting can be used as a form of strength training, increased stamina, and improve bone health, but he most common benefit of calisthenics over weight lifting is flexibility. Calisthenics use different movements unlike weight lifting, which are essentially isolated weighted movements that are like a robot because they the exercises are almost always done in the exact same way. Weight lifting has shown to be a faster way to gain muscle mass.

Based of the tests and research, both provide positive effects on the health and fitness of a person., but whether one is better than the other is dependent on the goal of that person. The first test showed that even in an elderly person weightlifting can increase strength and muscle stamina. Although the second test showed no change, one can conclude that the calisthenics training was nearly up to par with military training because there was no decline in their overall fitness levels. The third study shows that calisthenics can be very effective in weight loss, and has led me to believe that it is the better option to increase one’s overall health, but not strength.

How Does Sleep Deprivation Affect Us?

In college, it is very hard to get a full night’s worth of sleep. With schoolwork, clubs, Greek life, going out, and studying, there is no way that you will be able to sleep for a long time. I swear I have sleep deprivation so I wanted to research it and see what that really means.

In America today, at least 40% of Americans are sleep deprived. A typical adult needs an average of 7-9 hours of sleep each night. However, obviously most people do not have time to sleep that much. Most people average 6 hours of sleep during the week every night. Sleep deprivation can come from a sleeping disorder. Apparently around 70 million people in America have insomnia, they probably just don’t know it.

Sleep deprivation is not a good thing, and can cause short and long term affects and issues. First off, it is not healthy to be sleep deprived. If you do not get a long good night’s sleep, and then you will have problems in the daytime with alertness. You will have a hard time remembering things, concentrating, focusing, and staying awake. This can include falling asleep while driving which is very, very dangerous and risky. Surprisingly, 41% of people driving have admitted to falling asleep at the wheel at least once. It can be as dangerous as driving drunk. It is estimated that sleep deprivation is the cause for one out of every five car accidents that occur.

Many long term affects follow sleep deprivation. Not sleeping enough messes with your biological rhythms. Of course it will stress your body and make you tired, but it also puts strains on your interactions with others, your work, and other parts of one’s life. Losing just 90 minutes of sleep can cause you to be 32% less alert the next day. As a result of this, your motor skills can become impaired and your hormones can fluctuate inappropriately. Sleep deprivation also causes your immune system to be weak. This will make you become sick more often. It can also cause high blood pressure, heart failure, diabetes, and many more serious illnesses. Not getting enough sleep can also severely affect your mood. It can also affect your body and make you obese.

Your body needs sleep because it is the time when your brain organizes itself. Sleep deprivation can also make you develop Alzheimer’s disease faster. This is because if the body doesn’t have sleep, then the central nervous system that cleans the brain is not able to empty the information. Then cerebrospinal fluid starts to fill up throughout the days. This liquid starts to build toxins in it. If one is also sleep deprived this can cause brain cell loss.

While you sleep, your brain sorts and stores information that you got that day. Once we get information, it moves from our hippocampus to our prefrontal cortex, to the neocortex region, where long-term memories are stored. Every night this process happens. Without sleep, we wont be able to remember things and false memories may occur. You will incorrectly process memories if you do not get enough sleep and may confuse your events that have happened.

Now here are some ways to try avoiding sleep deprivation in college

  1. Try to avoid caffeine at night or even during the day. This will keep you up at night and will make it hard to fall asleep.
  2. Try to wake up close to the same time everyday. Do not sleep in on weekends and try t keep the same sleep schedule.
  3. Do not watch TV at least an hour before bed.
  4. Do not do homework right before bed or use your computer.
  5. Put your phone down at least an hour before you want to fall asleep.

Do Females Have Better Memory Than Males?

It’s the battle of the sexes! The never ending power struggle between man and woman, but let’s be honest both sexes excel in different areas of life. No matter how much I study for an exam, it always seems that I have a difficult time retaining the information. The opposite can be said when my female counterparts study for an exam. They always seem to do a lot better than I do even when we are in the same classes and we put in the same amount of time studying. What’s even more crazy is that we study together and compare notes. After seeing a pattern, I started to wonder maybe females are more able to spit out information on an exam than males. Of course, this is only a small group of people, but I decided to look into it. I also realized that the differences in memory didn’t just stop at studying, but in males forgetting other things like birthdays, appointments, mailing something, etc.

One researcher out of Hamilton College who dedicates her time to the gender and memory connection attributes it to females being more able to link memory to events that invoke emotions. She discusses how when girls are describing when something happened they are expressing it through their feelings. Females generally are conditioned to elaborate by adding their feelings in their memory-making, which in turn allows them to be able to remember better. This is because memory as Azriel Grysman, the researcher, explains is “a pattern of mental activity, and the more entry points we have to what that pattern might be, the more chances we have to retrieve it.” Such entry points act as triggers to memories by doing something that recalls a past event and how it made you felt. So, how does this fit into the equation? Exams can be an emotional and stressful time for people and actually associating an exam to a memory of freaking out to study for one can keep that knowledge stored in your brain to strive for a passing grade. In other words if you had failed an exam or had been cheated on in the past and then the same thing were to be repeated that would bring about feelings of pain and discomfort, which you wouldn’t want to experience again, therefore change how you combat the situation. Grysman does not state why the same does not apply to males.

A study was performed at the Norwegian University of Science and Technology and was headed by Professor Jostein Holmen, who rounded up 37, 405 men and women from ages 30 and beyond. The participants were then given a questionnaire consisting of nine total questions that relate to memory. Such questions were of the nature of whether their memory has changed since they were younger or something like if they have problems remembering dates to what events occurred a few days or years ago. The conclusion to the study displayed 1.2% of women reported memory difficulties and that 1.6% of men had problems with memory. Eight of the nine questions had men reporting the most problems. It became apparent that as age progresses the harder it is for men to remember. With that said, they were unable to find a direct link as to why that may be.

Another study seems to only support that men have greater memory struggles than females. In this instance, 1,246 people of normal brain health and who were between the ages of 30 and 95, the researchers discovered that while memory started to decline for both sexes at age 30, male memory was worse than women overall, most notably past the 40 year mark. The hippocampus in males, which is the memory control center of the brain, was smaller in size compared to women. Neurologist Dr. Charles DeCarli, states that “The men’s hippocampus starts off a little bit above average in the young people in the study…But then it falls way below average in the older men as compared to the older women.”

Females have an even greater edge in the brain in the form of hormones that act for protection. The common one is estrogen, which shields from infections, heart disease, hypertension, etc. Males simply don’t have this defense like females do and even if a woman looses this advantage at an older age, they’ve had it for their whole lives up to that point and still have some effects working in their system. Dr Charles DeCarli also offers a hypothetical in saying that it can very well be a possibility that “Women may have developed skills and strategies over our evolutionary development to keep track of stuff that helps their memory that men just never acquired.” Something else to consider is that females aren’t at as much risk for vascular disease as males, which can come from things like smoking, hypertension, or diabetes. Any type of activity that disrupts the vessels will have an negative impact on the brain. article-1253208-086ED558000005DC-708_468x236l

Is There A Thing Such As “Too Much Running”?

         In the exercise crazed culture we live in today, it would  be completely understandable to assume that the more miles jogged a week or hours spent at the gym correlates to one’s physical and mental wellbeing. The media constantly aims to convince us that absurd amounts of exercise will result in model-type bodies displayed on TV and in magazines. Take Kate Gosselin for example, who reported to Us Weekly she feels best when she runs 10 miles every other day.  I personally feel better about myself when I squeeze a daily run into my hectic schedule.

 

         However, multiple studies have been conducted examining the adverse effects that distance running has on the body. Unfortunately, our society is brainwashed by the media and doesn’t understand that when it comes to vigorous exercise, more isn’t always better.  According to an editorial recently published in the British Journal Heart, people who work out too hard for too long may be less healthy than sedentary people and are more likely to die than moderate exercisers. The authors additionally examined decades worth of research regarding the effects of endurance athletics. Overall, the findings concluded that moderate exercise was good, but excessive exercising is damaging.  For example, in one particular German study, researchers compared the hearts of 108 chronic marathon runners and sedentary people. Shockingly, the runners had noticeably more plaque buildup, putting them at risk for heart disease. The following picture compares a normal, sedentary runner’s artery to a chronic runner’s artery. Plaque buildup in the arteries causes a decrease in blood circulation, and can eventually lead to several severe health problems.

         In another observational study, performed by scientists at Birmingham University, researchers tracked  52,000 people  (a combination of runners and non-runners) for 30 years. Runners reported a 19 percent lower death risk than those who did not exercise. However, the findings showed that too much endurance running has an adverse affect on one’s physical well being. The researchers concluded that running an average of 10-15 miles per week spread across three to four days results in the greatest health benefits. For example, those who followed the recommended guidelines risk of death dropped by 25 percent. There are endless negative side affects that excess running has on the body. During a strenuous workout, the  body works overtime to burn sugar and fat for fuel, creating a smoke substance in the body.  The “smoke” that travels through one’s  system binds with cholesterol to create plaque buildup in the arteries, and damages your cells through a process referred to as oxidative stress. James O’Keefe, Director of Preventative Cardiology at the Saint Luke’s Mid America Heart Institute of Kansas City claims, “Your body is designed to deal with oxidative stress that comes from exercise for the first hour, but prolonged intense exercise causes excessive oxidative stress, which basically burns through the antioxidants in your system and predisposes you to problems.”  However, researchers across the board agreed that these findings are not a reason to give up running forever. As O’Keefe additionally claimed, “Exercise is the most important component to a healthy lifestyle, but like any powerful drug you’ve got to get the dose right.” Exercise in moderation reduces  the risk of heart disease, high blood pressure, type 1 diabetes, Alzheimer’s, dementia, and premature aging.

 

        In a  similar article with the catchy title,  “ Fast running is as deadly as sitting on the couch” scientists ran an experiment with similar findings. The study documented the exercise  habits of 1,098 runners. The findings showed that those who ran at speeds over 7 mph were nine times more likely to die prematurely within a twelve year span compared to those who ran around 5 mph ( a fast jog)  a few times a week. Statistics showed that vigorous runners were just  as likely to die as “couch potatoes” who never partake in physical activity. Peter Schnohr, a researcher from the Copenhagen City Heart Study quotes, “ There may be an upper limit for exercise dosing that is optimal for health benefits, and it is important to emphasize that the pace of jogging corresponds to very vigorous exercise”. Overall, the findings from the above studies are unmistakingly correlative: Running too fast/ too frequently causes alarming health problems, while running at moderate speeds and frequencies allows for optimum benefits widely associated with exercising.

         Overall, when it comes to your running routine, finding a happy medium is key. You should probably think twice about becoming a crazed marathon runner, as it leads to brutal side effects that are detrimental to one’s health. If you happen to love running like myself, just remember that everything’s better in moderation.

Why is sleep so important?

alarm-clock-sleep

In February of this year the National Sleep Foundation issued a new summary for the amount of sleep recommended for different age groups. According to their expertise they recommend no one should get less than 7 hours of sleep, however the younger the an individual is, the more sleep they should get. According to Charles Czeisler, Chairman of the board of the NSF, “This is the first time that any professional organization has developed age-specific recommended sleep durations based on a rigorous, systematic review of the world scientific literature relating sleep duration to health, performance and safety” (NSF). So why is the amount of sleep we get important enough to have guidelines set to advise us and potentially change our routines?

The reason behind us needing to be aware of it is because sleep or lack of it can seriously impact a person’s health and wellbeing. Sleep is extremely beneficial when an individual gets the right amount. This may be due to the fact that “Major restorative functions in the body such as tissue repair, muscle growth, and protein synthesis occur almost exclusively during sleep” (Rogers). Sleep helps maintain these vital functions that allow the body to recover properly from aspects of everyday life. It has many benefits that help an individual, some of the most important being reduced risk of health problems, healthier weight, sharper attention and much more.

One of the most important benefits of getting the right amount of sleep is that it reduces the risk of certain diseases and illnesses. When an individual gets less than the recommended amount of sleep they are shown to have higher levels of inflammatory proteins than individuals who get the correct amount. Inflammation is commonly associated with heart disease, arthritis, stroke, diabetes, and other serious health issues. So getting the right amount of sleep can curb inflammation and reduce the risk of these diseases linked to it. On the other hand, sleep deprivation can actually have negative effects. One study in 2010 “found that C-reactive protein, which is associated with heart attack risk, was higher in people who got six or fewer hours of sleep a night” (Sparacino). While another study “simulated the effects of the disturbed sleep patterns of shift workers on 10 young healthy adults. After a mere four days, three of them had blood glucose levels that qualified as pre-diabetic” (Griffin). These both show that sleep gives the body time to heal and lack of that after years can have a serious impact on health. That is why most people with the condition “Insomnia” usually have another health issue.

Not only does it help with serious illnesses, but also helps with something as simple as a cold. Getting enough sleep has been shown to strengthen an individual’s immunity. According to WebMD “Researchers tracked over 150 people and monitored their sleep habits for two weeks. Then they exposed them to a cold virus. People who got seven hours of sleep a night or less were almost three times as likely to get sick as the people who got at least eight hours of sleep a night” (WebMD). This is because if the body does not have the time to heal overnight, it weakens the immune system which makes it more likely for someone to catch a virus if they are exposed to it.

Another benefit of sleep is that it helps maintain a healthier weight. According to Dr. Rapoport “Sleep and metabolism are controlled by the same sectors of the brain. When you are sleepy, certain hormones go up in your blood, and those same hormones drive appetite” (Sparacino) The levels of a hormone called leptin, which is what makes an individual feel full, is what drops. That is why when people don’t get enough sleep it stimulates hunger, mostly for high-fat, high-carb foods and lack self-control is a result of being overtired. The claim that people that sleep less have a higher risk of being obese has been proven through multiple studies such as “one study that followed 500 people for 13 years found that people who regularly slept less than seven hours a night were 7.5 times more likely to be overweight — even after controlling for physical activity, family history, and demographic factors.” (Loria) So this shows that whether you’re on a diet or are just trying to be healthy, getting the recommended amount of sleep is an important aspect of not gaining weight.

The last important benefit is that it sharpens an individual’s attention. Without that sharp attention due to lack of sleep people are more prone to making mistakes, which can sometimes be dangerous. Research has found “Drowsy driving is responsible for 100,000 crashes and 1,500 deaths every year, according to the National Sleep Foundation. Almost 20% of serious injuries in crashes happen when there’s a sleepy driver involved” (Loria). Some studies similar to this have even shown that driving sleep deprived is almost as harmful as drinking drunk. Not only is sleep loss an hazard on the roads, but it can also be a danger in certain workplaces. Many accidents and injuries occur on jobs when there sleep deprivation is a factor. In fact some of the biggest disasters in history such as the 1986 Chernobyl nuclear meltdown or the Exxon Valdez oil spill were a result of this problem. Due to issues like this many companies have put in place regulations on how many hours workers can work to allow them to get more sleep.

So overall, what is the importance of sleep? Well, according to many studies getting a healthy amount of sleep or having a lack of sleep overtime can actually have a huge impact on your health and wellbeing. It can effect important aspects of life such as risk of health problems, weight, and sharpness of attention. However, there are many more positives of getting the correct amount of sleep. If the benefits alone don’t change your mind, maybe the consequences of not getting the correct amount of sleep will encourage you to get those important extra hours in. Sleep is such an easy way to improve many aspects of a person’s life, so if you have the opportunity, making sure you get the recommended amount of sleep is one of the best things you can do.

How harmful is tanning for your eyesight?

Being a girl in state college who loves to tan, of course one of the first things I did here was sign up for a monthly package of indoor tanning.  I tan indoors in my hometown too, and I used to wear wmrcJxMWx0QzXu7MIO5_RjQQink-ease, which were little disposable eye protections for your eyes while tanning.  Within the past year or so, I stopped wearing eye protection.  I recently went to the eye doctor because my sight has gotten so much worse, and I think it is because of the lack of eye protection when tanning.  So, I set to find out.
tanning-bed.ju.topWhen you think about it, people always wear sunglasses to protect their eyes, so why not wear something when tanning indoors?  It is the same idea.  According to the Health Physics Society,  tanning indoors exposes eyes 100x more than the sun does to ultraviolet radiation.   In the tanning bed, the ultraviolet radiation has direct contact with your eyes.  Photokeratitis is a short-term issue for your eyes from tanning.  It is when your eyesight becomes hazy, your eyelid swells, there is eye tearing, and pain.  Eye cancers can also be caused by indoor tanning, as well as skin cancers.

Another effect of UV light on the eye could be pterygium, which is when the conjunctiva grows on the surface of the eye.  It could become harder for one to see because the pterygium now goes over the middle of the cornea, which is what you see out of.  You can get rid of this through surgery, but it can keep coming back.

285-JustSayNo

Philip R. Rizzuto, MD, from the Warren Alpert Medical School of Brown University in Providence, Rhode Island, stated, “UV damage to the eyes may result in the development of cataracts . . . as well as cancer of the uvea, which is the middle layer of tissue under the white of the eye,”. (Eye Smart)  Another problem that can occur is you can get a corneal flash burn.  This is when a lot of UV rays cause your cornea to burn.   The eye will then become watery, hazy, painful, red, or the eyesight could become worse.

Not many studies have been done on indoor tanning and eye damage.  Scientists say it is harmful, but no actual studies (worthy of commenting on) have really been done.  If I were a scientist researching this field, I would conduct a controlled experiment. It would not be able to be a double blind procedure because the controlled group would know if they had eye protection or not while tanning.  I would get a large group of people, maybe 400, and test their eyesight.  They all must have 20/20 vision and be in good health.  They would all tan three times a week in the same level bed.  Half of them would wear eye protection and the other half would not.  After a month, an optometrist would check their vision once more.  They would then report who’s vision worsened and who’s did not.  This would be a very good way to test my hypothesis.

tanning_bed-NO

Next time you want to hit the tanning bed, think about how it could be affecting not only your whole body, but your eyes as well.  After doing my research on this post, I think I have decided not to sign up for tanning next month…

Exercise

All my life I’ve played sports, so I never really had to worry about fitting in a gym session. It was a big transition coming to Penn State and having to plan out what times I could go/ if I could even fit it in with my busy schedule. I started to see a change in my body that I didn’t like, so all I cared about was getting my high school self back. What I never thought about were the other benefits that exercise brings for your body. I wanted to learn more about how exercise can really help your body in more ways than just looks.

According to the Mayo Clinic, there are 7 benefits of regular physical activity. The first one is that it controls weight. I think this is the most obvious one that people automatically think of. The second reason to exercise is that it fights diseases. It can help with heart disease, high blood pressure, and cardiovascular disease. #3: improving your mood. Exercise triggers a series of chemicals in your brain that relax you and can improve your mood. Reason 3 lingers into reason 4. Since exercise improves your mood, it also improves your energy. It obviously gives you more muscle and stamina, and these things cause your lungs and heart to function better, increasing energy. #5: better sleep. Exercise helps you fall asleep faster and be able to achieve a deeper sleep. Number 6 states that exercise can improve your sex life. Youll be more energized and feel more confident in yourself. Lastly, It gives you away to enjoy life and have a new hobby.

2013-sia-exercise-chart1_tcm7-166377

“Stress in America” did a survey to see what percent of Americans participated in exercise. “The survey found that more than one-third of adults (37 percent) report exercising less than once a week or not at all. Only 17 percent of adults report exercising daily.” Knowing the benefits of exercise may motivate people to work out more. “”Fifty-three percent of adults say they feel good about themselves after exercising, 35 percent say it puts them in a good mood and 30 percent say they feel less stressed.” This is a great statistic for college students. Stress is such a horrible thing that can cause awful things to happen to our body.

Knowing that exercise can help fight these issues, why not take an hour out of your day to exercise. It can help you be calm and clear your head, so you can study smarter, not harder. (like Andrew says)

Is Holiday Weight Gain Just a Myth?

Festive cookies, cakes, and candies become all too accessible throughout the holiday season. These calorie packed treats might as well be at a snap of a finger, as they are provided in bulk at practically every holiday party and get together, club meeting, and welcoming home. You can not venture out to the local grocery/ convenience store without passing a glistening array of tempting holiday treats, and let’s not forget all the cute “Do It Yourself” holiday recipes that plague the internet and TV. With that being said, tacking on a few “holiday pounds” by the time New Years rolls around seems 100% justifiable.

 

        It’s commonly assumed that the average American gains an average of five pounds or more between Thanksgiving and New Year’s Day, yet there’s little data out there to fully support this belief. On December 25th, 1995, the Cable News network reported that “The average american will gain 7 to 10 pounds before the New Year,” and a report from the Texas Medical Association claimed that “ Most studies show the average American gains 8 pounds throughout the holiday season.” However, these past claims are not backed up by credible sources, and therefore may simply be assumptions made by the media. Interestingly enough,  a scientific study was recently published  by the New England Journal of Medicine that measured the weight gain of 200 volunteers. The subjects were randomly chosen to ensure the participation of both sexes. Participants were chosen from several racial and ethnic groups and were from a variety of age groups (all above 18 years).   Notably, the subjects were all healthy, with no serious medical conditions reported.

 

        The study called for the participants to be examined on four separate occasions at intervals of six to eight weeks. At each visit, weight was measured to the nearest 0.01 kg on an electronic scale, wearing hospital gowns and no shoes. All participants were weighed at the same time of the day as their initial visit (taking into account meal times). Participants were also asked to complete a questionnaire at each screening addressing concerns such as stress, physical activity patterns, and forms of depression (for example, winter seasonal affective disorder). Subjects were then asked to describe habit changes that occurred in between each clinical visit. Doctors than inquired about how much the participants believed they gained during the winter holiday period, and their responses were recorded.

        The findings were less severe than prior beliefs. Complete data was available for 195 of the original 200 participants. The average weight gain during the holiday period was 0.82-3.35 pounds. This is only a slight increase when compared to the pre-holiday season, where the average weight gain was  0.4-3.28 pounds. Notably, throughout the post-holiday time frame participants lost one pound on average. In addition, it was found that most participants did not have reports of extreme weight fluctuation and in 50% of all measurements the weight differed from the previous measurement by no more than  2.2 pounds.

        About 15% of the participants claimed that they attempted to lose weight during the holiday period, but their weight change was not significantly different from those who reported no such attempts. Additionally, no third variables of sex, race, or socioeconomic status were found to affect the data. Lastly, the amount of weight change throughout the holiday season had no great correlation with the original BMI of the participants.

        Overall, the study’s findings prove that the widely perceived notion that Americans tend to gain a significant amount of weight over the holidays wrong. For 

        On the bright side, dietary experts assert that there is a way around gaining even just a couple extra holiday pounds. In an article published by Susan G. Rabin titled “ 10 Ways to Avoid Holiday Weight Gain,”  doctors claim that portion control is key. As I mentioned earlier, alluring sugary treats are constantly present during the holiday season. However, indulging in a piece of pie or a cookie here and there will not cause much harm. The article touched upon some additional helpful tips to combat the season. Experts suggest eating something light before arriving at a holiday function, pacing yourself, and keeping tabs on what you consume during a holiday party in order to avoid holiday weight gain.

The Turkey Affect

Every year the debate arises just prior to thanksgiving, does turkey actually make you tired? There is belief that the tryptophan inside of turkey causes people to become exhausted. Tryptophan is an amino acid that is necessary in all human diets because one’s body cannot produce it. Along with turkey, it may be found in other meats, cheese, fish, and cheese. Its purpose is to help in producing a B vitamin known as niacin, which is used for digestion, and in forming serotonin. Serotonin plays a role in forming melatonin, which is a hormone that affects sleep and wake cycles. The tryptophan does play affect sleep, but is it enough to make people feel tired and drowsy after their thanksgiving feasts?

Turkey

Scientists at the Cleveland Health clinic put this theory to the test. Their study had the hypothesis that an increase in turkey intake will proportionally increase one’s tiredness. They had 16 infants divided into two groups, giving one group baby formula that contained tryptophan and the other received a placebo formula. The same test was also conducted on a group of young adults. The infants who consumed the formula with tryptophan had better regulated sleep compared to the group that consumed the placebo. The young adults tested received different samples with different doses of tryptophan. The group who received the smaller dosage had better sleep than those who received a larger dosage. This could suggest the possibility that maybe tryptophan works like a dosage and a certain dosage affects one’s sleep the most.

 

 

What-is-tryptophan-why-supplementation-provides-a-better-sleep1Based off the information in this study, the average amount of turkey a person consumes at thanksgiving is not enough to cause drowsiness. Turkey contains less tryptophan than chicken. If tryptophan affected a person’s energy levels, chicken too would consequently make one tired. It may just be coincidence, but after a summer barbeque full of chicken, I cannot recall feeling drowsy or seen other people feel this way.

 

So if turkey may not be doing the trick, what is it that makes many people including myself fall asleep following the thanksgiving feast? Along with turkey other popular foods at thanksgiving include potatoes, stuffing, and pumpkin pie. If turkey does not cause
people to get tired what is the cause? According to Kim Sasso a nutritionist at Loyola also agrees it is not the turkey that causes the exhaustion, but instead it is the carbohydrates. Even if the tryptophan causes some drowsiness, there would be almost no affect after thanksgiving because of all the other transport and breakdowns going on throughout the body because of all the other foods consumed.

 

In conclusion to my research and the articles/studies I rejected the hypothesis that turkey, due to tryptophan, causes people to feel drowsy after their thanksgiving feasts. In order to prevent the post drowsiness feeling, cut down on the carbohydrates.

Dorm room transitions

While adjusting to living in a confining dormitory like those of East Halls, new freshmen are forced to acclimate from a coddling and personal academic environment of high school to an unforgiving jungle that embodies that of college. Here, where one single assignment could mean the difference between an A and a C in the class, freshmen must swiftly muster the discipline to manage their time efficiently enough to study while simultaneously establish a brand new social life. This intimidating task only begets further distractions to detract from studies, piling on top of the temptations of attending sporting events, concerts, plays, and club recruitment events. Students must assimilate early enough to prevent this incessant cycle from snowballing beyond control, and the antidote can be realized through the maintenance of personal health.

LoyolaMD_DormAlthough it might seem negligible among the many things slopped across your plate, maintaining proper mental and physical health is absolutely crucial to a successful college career. Wellness serves as the foundation on which all aspects of college life are situated, from studying to socializing. A 2015 American College Health Association study reported that about forty four percent of students “felt tired, dragged out, or sleepy during the day,” while about twenty three percent reported “sleepiness during daytime activities as more than a little problem.” (ACHA 2015). Students tend to neglect sleep, sometimes to pull all-nighters and study, yet sleep deprivation has been correlated to lower GPAs “because sleep affects concentration, memory, and the ability to learn” (Campus Mind). Sleep additionally alleviates stress and even helps maintain a healthy diet, aiding the prevention of the infamous and dreaded freshman fifteen. Molly Kimball, a registered dietitian and sports nutritionist at the Oschner Clinic, cites eating as “a way to exert control for many freshmen when they feel little control in many areas of their lives” (Freshman 15 Means More than Weight Gain). In students’ free time, they often disregard exercise, as it is overshadowed by temptations to socialize or sleep. The aforementioned American College Health Association study concluded that about forty-seven percent of students satisfy the physical activity guidelines recommended by the American College of Sports Medicine and the American Heart Association. Beyond obvious reasons like maintaining body weight and cardiovascular health, regular exercise is shown to support emotional wellbeing by relieving stress. Physical activity also provides energy to power through a demanding schedule. Although these statistics all reinforce that personal health as essential to each student’s career, many still seem to neglect taking care of themselves.

A Kickstart in the Wrong Direction

A Kickstart in the Wrong Direction

It is said to be common knowledge that the average energy drink is not good for the average human being, and personally, I love energy drinks, however lately I started to feel different after I drank my favorite energy drinks. Naturally, I got nervous, and even though I’m currently fine and writing this blog, I decided that I would do a little research to educate the masses on how much energy is too much energy. The first step in finding my answers was figuring out that caffeine can literally cause an overdose, much like an overuse of drugs. Caffeine is also a neurotoxin which means that it could actually make an individual have slower and less efficient brain performance. There are other factors in how much caffeine one can consume in a day other than what they do normally. For example, for those prescribed ADHD medication, any extra caffeine could be life threatening.

If you’re reading this blog, I had hoped by now you’d be scared to pickup another life threatening energy drink. However, as I sit by and enjoy my Rockstar fruit punch flavored energy drink, I have some great news. It is actually extremely difficult to straight up overdose on caffeine. While it is still very possible to overdose, one study from medical daily says that the average 125 pound person would have to consume a total of 107 standard sized cans of Red Bull in order to overdose. This study however does not take into account at what point you would most likely have a heart attack, but to straight overdose and die from energy drinks solely it would take over 100 energy drinks. According to the same study, 200 to 300 mg’s of caffeine is safe for one day. The drink I am drinking right now is 240 milligrams. If only 200 to 300 milligrams are safe why are companies allowed to sell single drinks that fall into that category? In addition to this fact, should the government put a regulation on how old a person should be to buy energy drinks? After all if its safe for an adult to consume 200 to 300 mg’s it cannot be safe for a child to be consuming 240 in one sitting. A child is way more vulnerable to a caffeine induced heart attack. According to caffeine informer out of close to 4,000 calls to poison control regarding energy drinks, 51% of them involved children.

Caffeine is very addictive. In fact, after drinking a lot of caffeine for an extend period of time, caffeine becomes hard to quit and an individual will start to go through withdrawal and lack of functioning without an ample amount of caffeine. Caffeine also causes a number of other health defects like high blood pressure, an increased amount of stress, paranoia, vomiting, and other reactions.

From my own personal studies, I consume too much caffeine a day to keep going at the rate I am now. Now that I have answers and know how much is naturally handleable, I feel safer, but not better. I will be cutting down on my caffeine use and trying to kickstart my life without caffeine.

Is breakfast really that important?

Breakfast is the most important meal of the day… We have all heard it a million times from our parents, teachers, coaches, magazines and even TV. But when you roll out of bed at 6:45 to make it to school by 7:30AM, breakfast is not the first thing on your mind, but should it be? Unfortunately and fortunately for some, the importance of breakfast is not just another food myth. Not only will a nourishing breakfast will keep you full, it will provide you with the health benefits that are necessary to maintain a healthy lifestyle. Eating a nourishing meal in the morning provides you with energy, the ability to focus and concentrate better, an improved short-term memory, and even weight maintenance. AKA Everything that a student needs to be successful.

Pancake-Breakfast            Studies show in both adults and children that daily breakfast eaters tend to weigh less than breakfast skippers. According to CNN’s chief medical correspondent, Dr. Sanjay Gupta, you should eat a big meal, around 300 to 500 calories, within an hour of waking up. People who skip breakfast are much hungrier by lunch and dinner, so they tend to compensate for these missing calories by snacking and eating before bed. Consequently, they consume many more calories than the recommended amount and gain weight. Those who habitually eat a nutritious meal in the morning are more likely to maintain their current weight and have an easier time losing weight if needed (Skip Breakfast, Lose Weight Not so Fast).

People who skip that all-important meal of the day are at a higher risk of developing diabetes or even experiencing a heart attack. A new study out of Harvard looked at the health records of nearly 27,000 men over a period of 16 years. It determined that men who skipped breakfast were 27% more likely to experience a heart attack or to perish as the result of coronary heart disease. Skipping breakfast is linked to coronary heart disease because it prolongs fasting, which is a stressful state for the body. Leah Cahill, the author of the study, explains that, “As we sleep through the night we are fasting, and so if we regularly do not ‘break fast’ in the morning, it puts a strain on our bodies that over time can lead to insulin resistance and blood pressure problems, factors of heart disease.” (Why is Skipping Breakfast so Bad for our Heart Health?)

While breakfast will not make you a super human who doesn’t need to study for exams or practice in the off-season, it is definitely the first step towards a healthier lifestyle. Clearly, the importance of breakfast is not just another food myth.

Stem Cells: Ethical or Not?

Human stem cell research has become an extremely controversial topic. In 1998, James Thomson from the University of Wisconsin-Madison created the first human embryonic stem cell line. Reported by the National Institutes of Health, stem cells are different from any other kind of cell in the body. They have the ability to divide and renew themselves for long periods of time, they are unspecialized, and can give rise to specialized cell types. Because of the unique nature of stem cells, they have become of massive importance within medical research, potentially used for curing life-threatening diseases.

Especially in the case of embryonic stem cell research, extreme ethical concerns have occurred. Because of these concerns, legislation providing the use of stem cells in medical research has faced serious disapproval and hostility. With all the controversy surrounding stem cells, the public doesn’t have the knowledge about the many benefits for the health and medical fields. Their potential to treat many diseases in the future have scientists working hard to learn about these stem cell functions and how they can apply and treat some of the many serious diseases killing people everyday.

There are many potential applications of stem cells in the medical field. Stem cells have the ability to form cells and tissues to be used as organs in replace of damaged or dysfunctional ones. Unfortunately, the number of people on the transplant list is much higher than the number of available organs. Many people die while awaiting a transplant and if scientists could create these stem cell based made organs, it could save the lives of hundreds of people. Areas that stem cells can benefit include Parkinson’s disease, Type I diabetes, Arthritis, Burn victims, and cardiovascular diseases.

Dr. Marcelo Rivolta from the University of Sheffield’s Department of Biomedical Science, has spent 10 years researching how to separate human embryonic stem cells into the two types of cells that are crucial for hearing: auditory neurons and the inner-ear hair cells that translate sound into electrical signals. His research team conducted a study on deaf gerbils, injecting them in the inner ears with self-created spiral ganglion neurons. These neurons are the nerve cells, which pass sounds into the brain. On average, the gerbils recovered 46 percent of there hearing about 4 weeks after being injected with the cells.

The current benefits of stem cell practices are already well recognized and is expected that continued research will continue to bring up new treatments for diseases. Stem cells offer hope to suffering patients, providing optimism for effective treatment or maybe even a reversal of the disease.

The Real Secret Behind the “Food Coma”

We’ve all been there before. You eat so much food that you feel like you can’t move and end up staying in one spot until you fall asleep. Food comas are typically associated with Thanksgiving although they can come anytime of the year. They’re so common that people even blog about them! The popular myth is that turkey causes food comas but that is in fact not true. DNews talks about how turkey has an amino acid called tryptophan, that causes a release of serotonin and melatonin in the brain causing lethargy and tiredness, but many other non-vegan food such as chicken, yogurt, eggs, etc. also have tryptophan. Food comas, or postprandial somnolence, is primarily caused by carbohydrates causing tryptophan to go to the brain and releasing melatonin and serotonin. Melatonin and serotonin are chemicals that makes the body tired and eventually causes you to fall asleep. Amy goes more in depth in DNews about this weird phoneme but hopefully I summed it up enough. Basically, when you eat certian food with this special chemical (tryptophan) and food with carbs together, you get tired. Still confused? Watch this DNews video.

So how do we avoid the dreaded food coma?

Well, the short version is don’t eat that much but we all know that’s unlikely. This BuzzFeed article gives some pretty good tips as to how to avoid a food coma before it happens. It suggests to drink lots of water, avoid alcohol, eat greens, eat healthy snacks and breakfast, eat in small amounts along with a few others. Basically, thats what most sites tell you to do. But if you’re like me, you don’t plan ahead very well (note the time of this blog post in relation to the due date). I need a way to get over a food coma fast when its too late and I’ve already stuffed my face with turkey and creamed corn and everything else that comes with the holidays. The only thing I could really find on a cure for after you’ve eaten a lot, is to try to walk around and help clean up the dishes and whatnot. As I don’t like doing dishes much, I’d really like to see a study done to try to discover a way to stop the release of melatonin or how to get past the ridiculously full feeling faster. This is such a common problem for people it shocks me that no one has found any way to get rid of the food coma after it’s already set in.

I decided maybe I could change my diet and avoid the food coma this way. After I looked a little deeper to see what foods have the most tryptophan in them and found this list. Basically its all the good meat and other protein foods that are essential to human growth and are just really yummy. So I decided I didn’t want to cut those foods out of my holiday diet. Obviously, I love bread and pasta and decided I didn’t want to cut those out either. So that left me with no solution other than to eat in proportion, try to apply these tips before the food coma comes, and hope that someone will find a way to stop the melatonin and not make me sleepy and so full! Happy holidays everyone. Eat safe.

What Is the Science Behind The Memory of Our Dreams?

We all have dreams here and there.  It’s that fuzzy, confusing feeling when you wake up and debate whether what you were just thinking about was real or not.  Other times, you wake up, even more confused, because you have this instinct feeling that you had a dream, but now it is all a blur.  Ever wonder why this happens?  Why do we remember some, and then forget others?  And ultimately: What is the science behind the memory of our dreams?

While there has always been a great interest in the interpretation of human dreams, it wasn’t until the end of the nineteenth century that Sigmund Freud put forth some of the most widely-known modern theories of dreaming. Freud’s theory centred around the notion of repressed longing — the idea that dreaming allows us to sort through unresolved, repressed wishes. Humans construct dream stories after they wake up, in a natural attempt to make sense of it all.  While previous studies have already indicated that people are more likely to remember their dreams when woken directly after REM sleep, new studies are digging deeper.

o-DREAM-FACTS-DREAMS-DREAMING-facebookAccording to new research published in the Journal of Neuroscience, Cristina Marzano and her colleagues at the University of Rome have made significant discoveries in explaining how humans remember their dreams. The scientists predicted the likelihood of successful dream recall based on a signature pattern of brain waves. In order to do this, the Italian research team invited 65 students to spend two consecutive nights in their research laboratory.

During the first night, the students were left to sleep, allowing them to get used to the sound-proofed and temperature-controlled rooms. During the second night the researchers measured the student’s brain waves while they slept. Our brain experiences four types of electrical brain waves: “delta,” “theta,” “alpha,” and “beta.” The Italian research team used technology to measure the participant’s brain waves during the five stages of sleep, especially the REM stage.  The students were woken at various times and asked to fill out a diary detailing whether or not they dreamt, how often they dreamt and whether they could remember the content of their dreamsbrain-waves-during-sleep-and-rem.

Participants who exhibited more low frequency theta waves in the frontal lobes were also more likely to remember their dreams.  The researchers claimed that it is the same electrical oscillations in the frontal cortex that make the recollection of episodic memories possible. Thus, these findings suggest that the neurophysiological mechanisms that we employ while dreaming (and recalling dreams) are the same as when we construct and retrieve memories while we are awake.

Although the conclusions of the study seem logical, I found them to be completely observational.  By not providing us with any data, the study is very unconvincing and is instead based on a team of scientists’  knowledge.  I am left wondering many things.  Are these facts or assumptions and was there a difference in data between the first night and the second?  The study is missing a lot of crucial information, and therefore the central question is still unresolved.  As Andrew has mentioned in class, scientists frequently get things ‘wrong’ and our intuition is lousy.  The same goes for this study, which merely jumps to conclusions.

In another recent study conducted by the same research team, they used the latest MRI techniques and found that vivid, bizarre and emotionally intense dreams (the dreams that people usually remember) are linked to parts of the amygdala and hippocampus. While the amygdala plays a primary role in the processing and memory of emotional reactions, the hippocampus has been implicated in important memory functions, such as the consolidation of information from short-term to long-term memory.wpid-dreaming-girl-thumb14856243

Here’s my take on it: I was also disappointed with the above study because even though it is a good start as to where in the brain dreams are affected, it still doesn’t tell us why our memory sometimes works and sometimes doesn’t.  I am still extremely curious as to whether there is something that is hindering these parts, causing us to forget our dreams or what confounding variables could be responsible in our ability to remember them.

In a new study, conducted by Perrine Ruby, it discovered that heightened blood flow activity within certain regions of the brain could help explain the great dreamer divide. In general, dream recall is thought to require some amount of wakefulness during the night for the vision to be encoded in longer-term memory.

The study included 41 males who had their spontaneous brain activity measured with Positron Emission Tomography as they were sleeping and as they were awake. Half the volunteers were considered “high dream recallers,” and remembered their dreams about five mornings a week, on average. The other half of the volunteers were “low dream recallers,” and only remembered about two dreams a month, on average.  Researchers found that the temporo-parietal junction, which processes information within the body and externally, was higher during both sleep and wakefulness in the “high dream recallers.” They believe this could mean these people are more reactive to sounds or movements in the night and briefly awaken.

This study did not necessarily prove anything; it is still not known what causes some people to wake up more than others.  I believe that the researchers speculated that this allows these people to sense environmental noises in the night and wake up momentarily, but they have not actually tested this out to see if it is true, therefore their conclusions are invalid.  In addition, by limiting the study only to males, the study does not have a wide enough scope to account for the whole human population of dreamers.  A better study would be to include both genders and of all different ages.

SO WHAT DOES THIS ALL MEAN?:Remembering-dreams-difficult-part-brain-1169 Everyone dreams during sleep, but not everyone recalls the mental escapade the next day, and scientists are still not sure why some people remember more than others.  Overall, I was dissatisfied with the findings.  With all studies considered, many scientists may think that they have found substantial evidence on why some people are high or low dream-recallers, however there still needs to be more studies done to explain this phenomenon; and maybe one day we will understand the complex world of dreaming.
