During adolescence, there is a natural tendency for one to go to sleep later. Plus, with immense technology, particularly mobile phones, our brains are tricked into believing that daylight is still there and is confused whether or not to sleep due to the emission of blue light. This may lead to sleep deprivation and with prolonged lack of sleep, we may end up having insomnia. As a teenager, myself, it is necessary that I learn to balance sleep, my social life and studies. So, it really makes one ponder, if a good amount of sleep is proportional to good grades. According to the research done by a group of students from the Department of Psychology in the University of Minnesota in 2010, manifests a “positive correlation between amount of sleep per night with GPA, and a very negative correlation between average number of days per week that students obtained less than five hours of sleep and GPA”. Surveys were distributed in classrooms on the University of Minnesota campus with questions regarding their sleep quality, quantity and their GPAs. It was found that students who slept for longer hours on average each night tended to have better grades indicating a clear-cut difference in the GPA of students who slept longer when compared to others.
Another research carried out by Megan L. Zeek and her team for the American Journal of Pharmaceutical Education, investigates sleep patterns and frequency of daytime sleepiness to assess the association between sleep duration and academic performance among students. Again a paper questionnaire was made for students at a pharmacy school to fill up. The results were that more than half of the students slept for less than seven hours at night during a typical school week. The percentage rose up to 80% during the days before an exam. Despite the sleep that they get at night, it has also been found that approximately 50% of the students felt drowsy and sleepy throughout their day at school every day. It is highly notable that this finding has led on to a conclusion of longer sleep duration the night prior to an examination resulted with higher course grades.
Thus, I believe it is essential for students and adults of all ages to understand the importance of sleep and to not forgo it for anything else. There should also be courses on the importance of maintaining good habits for a healthier life in colleges and schools to have a head start in achieving good grades. How lengthy should an optimal session be? In fact, it varies from person to person and usually a normal person could go on sleeping for around six to ten hours, with eight hours being the most desirable. Through these findings, one thing is clear, which is that the longer the duration of your sleep, the higher your GPA. But what happens when you oversleep?
Oversleeping can be caused by various reasons. One of them maybe that the lack of sleep throughout the weekdays may take a toll on a person’s circadian rhythm, and due to the non-regular patterns of one’s sleeping schedule, they may oversleep on the weekends to compensate the loss, which is not desirable in maintaining a healthy body. Another reason could be because of depression. Oversleeping can also be considered as a sleeping disorder just as how insomnia can be and the effects are almost like a jet lag. A person may feel tired all the time as their external bodies may not be able to synchronize with their internal cores. People with these conditions tend to nap excessively during daytimes as well, which can result in the bad moods and temper of a person. According to some researchers, they suspect that oversleeping may decrease levels of serotonin, an important chemical and neurotransmitter in the human body which helps in the regulation of mood and social behavior.
