Bedtime=Lights Out!


Technology has been increasingly thriving over the past centuries. Lightbulbs, clocks, phones, computers, the internet, televisions, cars, washer machines, dryers, microwaves, ovens, guns, you name it. These amazing inventions have been making human life easier and better… or has it? Is all of this new technology affecting us negatively, which is making our health worse?

Studies show that the reliance and use of technology could actually affect your health in a bad way. According to the National Sleep Foundation (NSF), sleep “can affect sleep deprivation and lack of sleep, the consequences… adversely affect their performance, mood, family relationships, the driving habits, sex life and general health of the individual”(Say 1). Most importantly, it affects a humans sleep. Texting, watching television, playing video games emailing, blogging, talking on the phone, and more before bedtime can skew the body’s sleeping patterns. Using technology before bed causes a human’s body to be more tired the following day(Say 1). Exhaustion could lead to bad working habits, unsafe driving, lack of effort, and more.


The reason why technology increases exhaustion is because of the exposure of light. According to Charles Czeisler, a Harvard Medical School Scientist, light affects a humans metabolism and the amount of melatonin released inside the body(Say1). Melatonin is a hormone that reduces the amount of sleep a person receives and it affects our ‘human clocks’, which messes up our sleeping patterns(Study 1).


The NSF has done studies in the past which have proven this theory. According to one of their studies, a survey showed that 95 participants used some sort of technology before bed and two-thirds of them admitted that they were tired throughout the week(Say 1). Studies then show that teenagers (ages 13-18) are the most vulnerable; 22% of the members that fit this category admitted to be constantly tired during the week(Say 1). Another study, conducted and written about in the journal Applied Ergonomics, showed that the exposure to technology/light decreased the amount of melatonin in the body(Study 1). The researchers gathered multiple volunteers and had them play games, watch television, and use other technology while measuring the amount of light that their eyes received(Study 1). After the study was conducted, they found that the light reduced their levels of melatonin by 22%, which has been consisted with other experiments.

I believe that this experiment is great since the researchers used a large and random selection of people. Also, since it is consistent with other experiments, it makes it seem more valid. However, the experiment could be flawed due to chance or confounding/third variables. Some confounding/third variables could of been other random exposures of light in the room, a persons health (how good or bad their eyes are), and the amount of sleep they got prior to the testing day.

What do you think?

The truth about cellphones. The bad, the worse, and the ugly

Today’s world is run by technology and modern inventions. One device that is at the top of it all is the cellphone. Now a days who doesn’t have one? They control our lives. We use them to communicate, organize information, browse the web, and even just to entertain ourselves. Although there are many benefits to our phones, there are also a lot of negative effects it has on us that many of us aren’t even aware of.

One of the many negative effects that constant cellphone use causes is an increase in risk of illness. Believe it or not your phone is one of the most germ-infested objects that you may come in contact with throughout the course of a day. In just a 24 hours span, a phone may encounter many germ-infested places such as your pocket/purse, your hands, and even your face. You use it while you’re eating, you use it at the gym, and you even use it while going to the bathroom. As a matter of fact speaking of bathrooms, cellphones carry ten times more bacteria than most toilet seats.

Another issue that we have all recently seen is a rise in automobile accidents caused by texting. People are so focused on being on their phones while driving that they don’t pay attention to the road and risk putting other peoples lives in danger. It has been recorded that texting and driving makes you 23 times more likely to crash and causes 1,600,000 automobile accidents per year. Even talking on the phone instead of texting is dangerous. Even though your aren’t looking at your phone anymore you are still distracted by your phone and wont have both hands on the wheel. Being concentrated on your phone dramatically reduces your reaction time, and nothing can reduce the risk besides not using the phone while driving all together.

Not only can frequent phone use have negative psychological effects, it can also be physically damaging. Constant cellphone use has been linked to chronic pain in numerous studies. It is doing us harm in ways we would never imagine. “Cell phones require constant use of your hands, especially when sending text messages and e-mails. Responding to messages at rapid speed can cause pain and inflammation of your joints”. This leads to conditions such as carpal tunnel, a condition in which there is excessive pressure on the median nerve located in the wrist that allows feeling and movement to parts of the hand. Carpal tunnel may lead to weakness and muscle damage in the hand and fingers.

Along with all of these negative effects, constant cellphone use has also been linked to loss of vision and even more severe, brain cancer. So you tell me, is all of that worth it. Of course I’m not telling you to completely get rid of your phone but using it less often will be sure to lead to better results in the long run.
