Sleep deprivation seems to be an increasing problem with people of all different age groups. It is related to many different health concerns. Nearly fifty percent of adults fail to get enough sleep. According to the national sleep foundation, teenagers need at least 9 hours of sleep a night, but 80% get a lot less than that. Due to the lack of sleep at least 28% of high schoolers fall asleep in class, 22% fall asleep while doing their homework and 14% arrive late or miss school entirely because they oversleep. Based on the article It is obvious that school age children need a lot more sleep than they are getting. As sleep continues to depreciate students have a harder time concentrating. Feelings of depression, also starts due to sleep restriction.
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. (1)
The scans took place at baseline and 24hrs later after a night without sleep to a maximum of 2.5hrs. The study consisted of 12 women with unipolar depression and 15 healthy women using proton magnetic resonance spectroscopy acquired at 1.5T. (1) They assessed 3 neurochemical signals(referen...

...k room, a symptom of chronic sleep loss. Another group , who for a period of time, went to bed 60-90 minutes earlier than their regular bedtime. These students felt like they had more energy, and felt more awake. They performed significantly better on test of Psychological and mental acuity(4).
The effects of 43 hours of sleep deprivation on executive control functions: event- related potentials in a visual go/no go task.
Procedure
40 participants were assigned to either a TSD or a control group(no sleep deprivation; for TSD group). Electroencephalogram(EEG) recording were taken using 32 electrodes while a GO/No go task was administered. The amplitudes of the NO go-N2 and the no go P3 were smaller in tsd grouping terms of prolonged latencies.
Conclusion
Results shown that executive control functions were recognized as being impaired after 43 hours of TSD.
Chronic sleep loss is becoming more common in modern culture and less restricted to sleep-deprived diseases such as insomnia. Suggested to be the result of a number car, industrial, medical, and other occupational accidents, sleep deprivation is beginning to be recognized as a public concern. As a result, the Centers for Disease Control
Sleep deprivation is a commonplace occurrence in modern culture. Every day there seems to be twice as much work and half as much time to complete it in. This results in either extended periods of wakefulness or a decrease in sleep over an extended period of time. While some people may like to believe that they can train their bodies to not require as much sleep as they once did this belief is false (1). Sleep is needed to regenerate certain parts of the body, especially the brain, so that it may continue to function optimally. After periods of extended wakefulness or reduced sleep neurons may begin to malfunction, visibly effecting a person's behavior. Some organs, such as muscles, are able to regenerate even when a person is not sleeping so long as they are resting. This could involve lying awake but relaxed within a quite environment. Even though cognitive functions might not seem necessary in this scenario the brain, especially the cerebral cortex, is not able to rest but rather remains semi-alert in a state of "quiet readiness" (2). Certain stages of sleep are needed for the regeneration of neurons within the cerebral cortex while other stages of sleep seem to be used for forming new memories and generating new synaptic connections. The effects of sleep deprivation on behavior have been tested with relation to the presence of activity in different sections of the cerebral cortex.
Sleep Deprivation and the correlation with depression can cover a range of topics. Stemming from how depression occurs, the symptoms affecting human bodies, treatments, other related sleep disorders. There are several different models used such as the polysomnographic research, (Palagini, 2013) integrative, prospective and retrospective models; along with chronotherapists in a controlled environment stimuli (light and sleep deprivation) seen in Hemmeter’s research was used also in order to conduct the experiments. The literature review critique articles relating to sleep deprivation and correlation with depression.
When most people think of sleep, they think of it as a relaxed but yet not a very important part of our daily lives. What most people don’t understand is although we are not up and moving around and getting tasks completed, our brains are still very active. Without sleep our bodies do not function correctly on a daily basis, and our mental state is at risk.
Sleep is one of our basic needs to survive and to function in day to day operations, but not everyone needs the same amount of sleep. Some people can survive on very little sleep, i.e. five hours a night, and some people need a lot of sleep, to the extend that they are sleeping up to 10 to sometimes 15 hours a night (Nature, 2005). According to Wilson (2005) the general rule states that most people need from seven to eight hours of sleep. The deprivation of sleep in our society in continually increasing with the demands in society increasing work loads, the myth that a few hours of sleep is only necessary to function properly and that sleep is sometimes considered as killing time (Nature, 2005). Sometimes sleep deprivation is also caused by other situations like sleep disorders, i.e. sleep apnea, chronic insomnia or medical conditions such as stress (Wilson, 2005).
Those that have a bad sleep pattern most likely suffer from sleep deprivation. Sleep deprivation is a significant loss of sleep that results in concentration problems and is detrimental to one's health. The symptoms of sleep deprivatio...
Moreover, sleep deprivation occurs when an individual is in sleep-restricted state. Sleep deprivation may have an unfavorable effect on the body and the mind, however it can only have this effect through monism. It is possible to infer that mind and body can in fact not be separate in terms of the effect of sleep deprivation on a human.
Sleeping is something that is an essential part of human nature and is a must in order for one to be a functional human being. Sleep is an idea that is accompanied by many wives’ tales, including the ideas that one needs seven to eight hours of sleep each night and alcohol helps one fall asleep and sleep more soundly. One myth about sleep is that during sleeping, one is in a state of nothingness. In truth, however, it has been discovered that during sleep the brain is active, variations in heartbeat and breathing occur, and the eyes and ears are active throughout the time of sleep. These activities during a person’s sleep are important because they help that person be more aware, awake, and alert during consciousness. If all of these important activities occur during sleep, why is it that people are so willing to short themselves of this vital activity? Although much about sleep still remains a mystery, research and experiments continue to show how important sleep is to each and every person. Throughout this paper, I will discuss sleep and the effects that it has on performance and health, especially in college students. A college student’s sleeping pattern is a reliable indicator to their level of performance in the classroom and other school-affiliated activities, as a lack of sleep leads to decreased performance. Sleep is directly related the level of performance and health in an individual; the more rested a person is, the better that person will perform and feel (Dryer, 2006).

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
Being deprived of sleep has many risks. Some major health risks of sleep deprivation is loss of memory and
Obesity: Our weight also depends on our sleep duration. Studies show that people who slept for 9-10 hours are more likely exposed to obesity compared to those who slept between 7-8 hours. Even when food intake and exercise were taken into account, this link between sleep and obesity stayed the same.
Lack of sleep negatively affects many different aspects of your life and making sure you get enough sleep will save you from: mood swings, loss of focus, change in behavior, and difficulties in everyday tasks.
Sleep is a very important factor in the human function. Our body and brain is able to reset itself and rejuvenate while we sleep. When we do not get the required amount of sleep, we start to feel lethargic and foggy minded, because our mind and body wasn’t able to replenish itself. Sleep is imperative that an insignificant rest deficiency or lack of sleep can affect our ability to remember things; decisions and can affect our temperament. Chronic sleep deficiency can get the body to feel agitated and it could lead to serious health problems such as, heart problems, stress, acne, and obesity.
Sleep plays a vital role in a person’s mental well-being. Sleeping affects how well people think, react, work, learn, and get along with others. While a person is sleeping, his brain is preparing to help him learn and remember information. A good night’s sleep enhances learning and problem solving skills. It is very important for the students to have sound sleep as it can improve their concentration, memory and creativity. Furthermore, having enough sleep increases the ability to m...
