Yoonjung et al. reports that “sleep plays an important role in the brain’s reparative and integrative processes.” Without sufficient sleep, the brain cannot properly repair itself or complete integrative processes. Perfect et al. concludes, “Regarding the impact of sleep on performance in school, total sleep time (TST) has been associated with more school problems and lower grades.” “Why Is Sleep” also concludes that sleep loss in students is directly connected to lower grades and trouble paying attention. It is evident that the less sleep a student receives is correlated to his or her poorer academic performance.
People who have this condition are involved in risks such as motor vehicle and work related accidents. They also have poorer health when compared to other people. The signs of hypersomnia are; excessive quantities of deep sleep, sleeping for a duration of 10 hours or more at a given time, excessive sleepiness that is not reduced by taking naps, and trouble with being awake during the day. Hypersomnia interferes with a person’s relationships and prevents them from enjoying the activities they take part in. Additionally, it makes management of daily activities and responsibilities at work a great challenge.
Even teenagers still need to get enough sleep to avoid suffering the consequences of being sleep deprived. According to Peri (2010), sleepiness slows down one’s thought processes and it impairs memory which makes learning difficult. His study also showed that the quantity of sleep affects the cognitive and mental health of a person. With his study, he was able to conclude that lack of sleep can lead to mood problems and can hinder a person from thinking clearly. Studies show that having the recommended eight hours of sleep is very important for the brain rejuvenates itself during sleep.
Often it is a product of the more difficult school work, that is exaggerated by the sleep-deprived brain. There are links between under-sleeping and high stressed students (Kingkade). At a biological level, the body releases more cortisol, the human stress hormone, when it is constantly tired and the brain can not manage stress as efficiently when it needs sleep. In a clinical study on the effects of sleep, Michael Bonnet and Donna Arand reported that “a higher level of stress is observed; tiredness, drowsiness and irritability increases; work effectiveness decreases and motivation usually falls down” (Orzel-Gryglewska). The most dangerous part of sleep deprivation is that it is cyclic in nature.

Although rare and extreme, cases such as these have been documented. Sleep deprivation can also be detrimental when associated with emotional trauma. When deprived of sleep during a time of emotional distress, people are at a greater risk of becoming psychotic and needing electroshock therapy.
First, sleep deprivation can impair the cognitive performance of an individual. The lack of sleep can decrease attention, working memory and impair vigilance.  Studies by Smith et al. have shown a decline in both speed of reaction and in accuracy of performance. [As quoted in 1] Besides that, Drummond stated that getting not enough sleep for 35 hours can impair free recall.
Abstract Sleep deprivation is expected to affect the cognitive and behavioral attitude of human beings. This study attempts to analyze the impact of sleep deprivation on the academic performance of the college students. The study uses an appropriate sample of 200 students and used personal interviewing technique to collect the data. The hypothesis are made by reviewing the past literature of the same field and expected that sleep deprivation affects negatively the behavior and academic performance of the students. SLEEP DEPRIVATION 3 Sleep Deprivation Sleep deprivation can appear in the living beings, included both human beings and animals, either in the form of lack of sleep during a certain period of time or a shorter period of sleep than the optimal sleep time.
Compare/Contrast Two Articles on Sleep Deprivation Many times people think they can accomplish more if they could eliminate so much sleeping time. However, they are only hurting their productivity if they lose sleep. Two articles deal with the issue of sleep deprivation. The College Student Journal published an article about the grade-point average of college students and sleep length, while U.S. News & World Report produced an article dealing with the lack of sleep in America and its effects on performance. The articles gave different types of results from different kinds of data with different degrees of definiteness.
These sleep stages are necessary to regulate the different states of wakefulness and sleep. According to Williams, “Insomnia or difficulty in initiating or maintaining sleep is almost part of everyone’s life” (29). Insomnia is a result of sleep deprivation, which can lead to further effects such as stress and aging. Regular sleeping patterns can drastically change for someone who is experiencing sleep deprivation.

Another important finding was that lack of sleep disrupts subjects’ reasoning ability and creativity. Although some research indicates that sleep deprivation of 45 hours or less is sufficient to cause these effects on cognitive performance, some researchers argue that wakefulness of 46 hours or less is too little to exhibit a significant effect. Therefore, further work is required to establish this[1,2,3].

It can be concluded that overall performance of a sleep deprived individual is worse than those who had sufficient rest.
