The Medicine of Music

In one of my previous blog posts I discussed how certain types of music had the ability to get us out of bed in the morning and get us started for the rest of the day, but can it heal us? Many of us know that our favorite tunes can make us feel calm and reduce stress, it may even cure a broken heart! Research has found that music’s abilities go beyond that to help humans be cured of certain diseases.

One of these diseases in which music made the sufferer feel better is Parkinson’s disease. Researchers claim that the vibrations in certain music types made the Parkinson’s less severe. In an experiment in which 40 patients with the condition were exposed to one minute increments of low frequency 30-hertz vibration on and off for 10 minutes, most of them reported feeling reduced symptoms. This is very promising that it is possible to develop some sort of vibration therapy to help with the unfortunate disease. One problem I have with this study is that it was too black and white. Instead of exposing the patients to only 30-hertz vibrations for one minute, scientists should have experimented with other vibrations: fast and slow, for more extended periods of time. If they committed to more varied trials, the results could have been significantly more satisfying in that they could additionally decipher exactly which of the vibrations could help the patients the most.

Perhaps an even more significant trial was conducted on patients of Alzheimer’s disease. In this experiment the patients were exposed to 40-hertz sounds this time for 30 minutes a few times a week. After this so called “vibroacoustic therapy”, patients seemed to be improved in their condition. In one particular instance, one woman “could recall the names of her grandchildren more easily, and her husband reported good improvement in her condition.” Again with this trial, I think more could have been done to see which frequency within the vibroacoustic therapy worked the best with Alzheimer’s patients. Then, the therapy could therefore be perfected and used in regular practice to treat patients.

We know that our favorite songs can help  feel better if we are feeling depressed or anxious, but this evidence proves that certain sounds and vibrations have the ability to heal physical diseases just as well as everyday mental shortcomings.

“Early Blind” VS. “Late Blind”

People who have always been blind or have gone blind when they were a child are called “early blind” people, and their ability to make up for their lifelong obstacle is incredible. It’s always been known that blindness causes people to be able to hear more clearly, but there are numerous tests to prove that “early blind” people have more ability with almost every task than people with “late blindness” and especially those that are sighted but blindfolded. It makes sense that those who go blind so early in life have a lot more time to learn to make up for their lack of sight, and therefore are more skilled than those who have not learned or have had less time to learn. But how much more skilled are they with using their remaining four senses?

Scientists conducted a hearing experiment  which involved 3 groups of people: “early blind”, “late blind”, and sighted. The task, easier said than done, was to decipher which of  two tones played out loud was in higher pitch. As we can imagine, the “early” blind” people were able to outperform both of the other two groups. But interestingly, there was no significant difference in the performance of “late blind” and sighted people. This proved to Dr. Belin that the brain’s centers for sight and hearing and other senses are all connected in a way that if one dies, the others can make up for it. Therefore, the “early blind” has had more time for those other senses to step up to make up for the loss of sight. I think that instead of only having early and late blind people as volunteers to the experiment, it would be much more beneficial to our level of knowledge on the subject if there was a more varied selection of people’s experience with blindness. For example, having a “5 year blind” and a “10 year blind” to teach us about just how long the process of making of for lost senses takes.

Another experiment involved the same types of 3 groups, but this time tested the volunteers’ ability with their sense of touch. They were timed how fast each group could match 10 shapes with corresponding cut-out holes in a wooden board. This time, the two blind groups performed with similar performance, as the sighted volunteers struggled, yet improved a lot throughout the experiment. Just as in the other mentioned experiment involving 3 very different groups, I would have found it helpful to our understanding if there were more that 3 groups with people of less varied experience with blindness.

All of this evidence points to the fact that it is all about practice when it comes to improving everyday skills with the tall obstacle of living with blindness. Those that have been blind for longer have, in a way, an unfair advantage to the “late blind” because their connections of the sight, hearing, and touch centers of the brain have had much more time and adjust and make up for the devastating loss.

 

Is Marshawn Lynch Right to Eat Skittles for a Burst of Energy?

All star running back for the Seattle Seahawks Marshawn Lynch loves Skittles. The very few times we hear Marshawn talk on T.V., its often about his obsession with Skittles and how it started with his mother when he was a child. He habitually eats his Skittles on the sidelines during a game after a big drive in order to keep his energy levels up. But is Lynch right to eat such candy in the middle of a high energy NFL game? How do sugary candies such as Skittles effect our short-term energy?

We’ve all heard that sweets such as candy and soda make us “hyper”, especially children. But Dr. Aaron E. Carroll sternly rejects this “myth” and suggests that candy does not raise the children’s energy levels. Rather, parents are to blame for over-exaggerating their childrens’ behavior. He sites an experiment where an entire group of children were given a sugary-free drink, and half of the parents were lied to and told that there was sugar in the beverage. The results were that that those parents rated their children as being more hyperactive than the other group, “confirming that this myth is entirely in the parent’s heads.” But the thing that I find wrong with this experiment is the principle that once a children is drinking a soda which he assumes has sugar in it, he or she will be inclined to “act” as if they are under the spell of sugar. For example, I read about a study where someone brought a keg of unalcoholic beer to a party, and everyone drinking it acted as if they were drunk even though they were not. I believe the same principle applies to this expiriment in that the children trick themselves into hyperactivity.

Another study that was conducted my Dr. Tamborlane from Yale took a closer look at the 140128-lynch-skittles-media-day-600 screen-shot-2015-01-26-at-9-15-29-pmphysical effects of children that have been given sugar against children that have not. The results were that the kids that were given sugar had higher levels of adrenaline, which is consistent with Marshawn’s reasoning for consuming such junk-food. But what also was found was an increase in insulin with the children who consumed the sugar which is linked to ADHD and loss of focus, a sign that Lynch should rethink his decision. I believe that this simple experiment was conducted well in that scientists were able to effectively witness changes in the children who were given sugar that were not present in the control group. If the trial weren’t randomized, perhaps one could argue that reverse causation could be possible in that children with more adrenaline could desire candy more, but that is not the case here.

In an intense NFL football game, playing on a high energy team such as the Seahawks, I believe it is helpful for a star player such as Marshawn Lynch to consume sugar on the sideline. For the soul reason of the increase in adrenaline, which is so important in a high impact sport such as football, Lynch benefits from the Skittles; and everyone can see that on the field.

Nicotine Chewing Gum

Tobacco use has many consequences that   can negatively effect users physically, mentally, and even socially. Therefore, it’s no wonder why nearly 7 out of every 10 users desire to quit. So how do these addicts manage to eventually defeat their tobacco addictions? The solution for many is the process of satisfying their nicotine dependency through means other than tobacco consumption, known as Nicotine Replacement Therapy (NRT). This therapy includes items such as the nicotine patch, nicotine inhalator, nicotine lozenges, even nicotine nasal spray! But the most popular and proven most effective is the nicotine chewing gum.pack_shot

In a double-blind placebo-controlled experiment, out of 94 participants that were given the nicotine gum, 70 reported that it reduced their their urge to use tobacco, and 45 out of 93 that were given the placebo reported the same. The conclusion was that nicotine chewing gum is effective in improving the success rates of desired quitters, but my question is how does a placebo work in this instance?  Chewing nicotine gum is far different in taste and also in that the nicotine can be felt especially from a tobacco user. Other than the questionability of the effect of the placebo, I believe this study was well done in that the scientists found direct evidence of exactly what they were looking for: nicotine chewing gum positively effects the success rates of tobacco quitters.

Another study conducted in the United Kingdom observed the effects of quitting tobacco “cold turkey” against the effects of a gradual approach as we see in Nicotine Replacement Therapy. The study found that most of the users attempted the “cold turkey” method, with a 22%-27%  success rate, while the gradual method had a success rate of 12%-16%. According to this study, nicotine gum and other such products should not be used in an attempt to quit. Rather, users should just quit once and all together; but I disagree due to some problems with this study. First of all, this study was only conducted in the United Kingdom and therefore in a place with different culture and regular habits of the regular population than our own. Also, this was an observational study which involved the “random-digit-dialing” telephone survey in which the scientists merely asked questions over the phone, suggesting a level of dishonesty which is very possible in this instance. For example, one can say they quit “cold turkey” even though they may have had a few cigarettes along the way to help with the stress.

I believe that Nicotine Replacement Therapy, and more specifically nicotine chewing gum is the most effective way to quit tobacco use. Aside from the observational study, I see the experimental study as much more authentic because the scientists were physically there to conduct it, rather than surveying random people. This is a perfect example of the fact that experimental studies are the most effective scientific method of obtaining authentic data.

Traditionally among college students and professionals, drinking coffee or tea has proved to be the method of becoming energized for the long day ahead soon after waking up. But for many, consuming caffeine before getting their day started is a challenge: either they don’t have the time to make or buy coffee or tea, they don’t enjoy the way caffeine makes them feel, or they simply do not the taste of coffee or tea. So without caffeine, how can these people start the day off with a burst of energy right out of bed? The science behind several methods suggests that caffeine is not so essential after all.

Perhaps the most direct way is to take a cold shower. Effectively, putting a body into full contact with the cold water will jolt certain parts the brain associated with diminishing fatigue. A study mentioned in an article from the U.S. National Library of Medicine suggests that taking a shower at the temperature of approximately 20 degrees Celsius, “can result in activation of behavior and increased capacity of the Central Nervous System to recruit motoneurons.” This stimulation of motoneurons renders the participant feeling more active and ready to take on the day almost immediately. In my opinion, this study was conducted flawlessly in that the scientists were easily able to scan and interview participants in order to effectively find exactly what they were looking for: the treatment diminishing fatigue. Therefore, the scientists are not guilty of the “texas sharp-shooter problem” due to their directness.2014-04-14-5-surprising-reasons-to-take-cold-showers-2-fb-2

Another study, lead by Dr. Frederick Schaerf, suggests that listening to a personal playlist of one’s favorite songs can very effectively get them mentally and physically ready to take on the day. Using a PET scan of a volunteer’s brain, Schaerf found that the brains of participants that were listening to music released more dopamine than that of the control group. Under that finding, Dr. Schaerf claims that  “music does awaken the brain”. I think what he fails to explain is that how these rising dopamine levels in the volunteers’ brains actually “awaken” them. Overall, I believe this is a sound study in that the scientist saw a brain response in the volunteers that listened to music that was not seen in the control group. Also, we can rule out flaws such as reverse causation because rising dopamine levels in the brain will not cause music to play.

Especially as college students who generally have little time in the morning and are generally without coffee makers, these two studies can prove to be very beneficial in our lives. Having cold showers and music as necessities that every college student possesses, it is in fact easier than we thought to get our day started on the right foot without a cup of coffee or tea.
