However, the lack of sleep can come from our environment or from ourselves. Cornell graduate student, Rebecca Robins, found that when she researched how students talk about sleep, it was mainly in negative terms over eighty percent of the time (Pope 1). College students have some influence over their sleeping habits, but so can universities. The University of Louisville, for example, is having a “flash nap,” which is like a group of people having a quick nap and some universities even have sleep seminars (Pope 1). Participants in a sleep study took an eighteen-week course on sleep, then were evaluated for sleep improvement, but this test only had a limited number of subjects meaning it was not a reliable study (Hershner & Chervin 80).
Harris cites the large amount of people not getting enough sleep in hopes to raise awareness of this rising problem. Brad Wolgast, a psychologist at the University of Delaware, states “When you find depression, even when you find anxiety, when you scratch the surface 80 to 90 percent of the time you find a sleep problem as well.... ... middle of paper ... ...t naps are a great way to feel rested, but should be kept to about 15 minutes (Nelson 75). The problem with naps is that the napper doesn’t set limits for his or herself. Most people tend to nap for an hour, causing sleep inertia and making themselves even more tired. Sleep inertia can happen in as little as a half an hour of napping.

"Poor sleep has been associated with increased morbidity and mortality including obesity, diabetes, cardiovascular disease, and coronary heart disease," researcher Mark Wahlqvist of Monash University said in a release (Sleep and Diet, 2014). This is just an example how uneasy sleep can lead to many more consequences other than just a sluggish following morning. At University of Chicago a study done in 1999 showed that limiting someone to just 4 hours of sleep every night for the duration of 7 days resulted in healthy students to become ill. Many students had to receive glucose as well as insulin characteristics of diabetes.
Due to partial overnight sleep deprivation improving the mood of 50% of depressed patients, that would usually take days or weeks to see mood improvement. (1) The Canadian Medical Association was approved by the Capital District Health Authority Research Ethics Board to study and compare the neurochemical changes in healthy and depressed participants who had partially overnight sleep deprivation. Within a day overnight sleep deprivation can produce antidepressant feelings in some patients. (1) The study asked its participants to keep their regular sleep habits for the week prior to the study. The procedure was to scan two brain regions, which was left dorsal prefrontal area and the Pons.
More people checked no on “Dose lack of sleep affect your appetite?”, and very few check sometimes. “Do you think too much sleep is bad for you?” Believe it or not, but more people thought that if could never be too bad for you. The kids that filled out the survey most of them usually got 5-8 hours of sleep on school nights. The kids that filled this survey out were all in the age range of 14-16.
Sleep patterns and habits Our study revealed that the average duration of night sleep among Lebanese university students was 6.67 ±1.6 hours. A similar study among Palestinian undergraduate students by Sweileh and colleagues15 reported an average duration of sleep of 6.4 ±1.1 hours. This result was also comparable with a study among Korean college students who had a sleeping duration of 6.7 ±1.3 hours 19. Our results showed that 42% of the participants needed more than 30 minutes to fall asleep. These data suggest sleep difficulties consistent with research of the National Sleep Foundation as well as studies published among college students in USA which reported that more than 40% of Americans have difficulty falling asleep or have night waking 20.
Studies show that having the recommended eight hours of sleep is very important for the brain rejuvenates itself during sleep. A number of things contribute to the lack of sleep among teens. Glosser (n.d.) states that social life, caffeinated drinks, electronic media, depression and homework contribute to sleep deprivation among teens. He asserts that sleep deprivation in teens may also have biological causes because their body clocks are programmed to start later in the day, possibly for hormonal reasons. Due to an overwhelming number of academic requirements to be done, most students do not get sufficient number of sleep.
According to a survey completed by The National Sleep Foundation, only 20% of high school students sleep the optimal 9 hours on school nights and 60% of children under the age of 18 have complained that they are tired throughout the school day to their parents (“School Start”). Sleep depravity is very common among high school students. With disadvantaged sleep patterns, adolescents have decreased mental sharpness and ability to pay attention during school hours. Therefore, grades and test scores are lower than their potential. In fact, “a recent survey by the National Sleep Foundation showed that only 20 percent of teenagers report getting the optimal 9 hours of sleep o... ... middle of paper ... ...ld be an aspect school districts should evaluate.
Stages 3 and 4, called slow wave or delta sleep, are the deepest levels and occur mostly in the first third of the night.” Most high school students only reach the third or fourth level three times a night, which is the most vital. At this stage the body of the student is slowly repairing itself (Karriem-Norwood). These results of sleep absence have caught the attention of Dr. Mary A. Carskadon of Brown University who did an experiment of the effects of sleep in the body, which has revealed that students’ bodies have become accustomed to the circumstances it has been involved in. Denise Dador, health specialist, stated, “Experts say about 80 percent of high school students are sleep deprived. They’re biologically programmed to stay up late” (Dador).
Also, the brain uses this period for regeneration of brain cells. Thus, the brains of people who are sleep-deprived tend to shrink over time since the brain is unable to repair itself. When this happens, the prefrontal cortex (which is responsible for reasoning ability) shuts down and the locus coeruleus (LC) neurons take over. These neurons induce a state of panic and stress and these symptoms manifest themselves in sleep-deprived people. Also, IQ levels decrease after a night of poor quality rest and regularly cutting back on the recommended 7-8 hours of sleep can affect your ability to focus, think and memorize.
