Recommended: introduction to sleep deprivation topic
The purpose of this study was to identify effects of sleep deprivation on a person’s performance and function in physically and mentally demanding situations. The researcher obtained research on this topic through various search engines, such as questia.com and Google Scholar. The results of the searches produced many different areas of the subject, so the range of information was narrowed to several broad topics. The areas of performance the researcher chose were: general cognitive/motor; medical procedures; driving; and health. The research was conducted from October of 2007 until May of 2009. The researcher collected data for use in this study mainly through various respectable online resources in addition to books on sleep deprivation and disorders from the Stafford High School library and the Central Rappahannock Regional Library. Information was obtained from those sources to further develop each subtopic in the researcher’s investigation. The research pertained to the specific effects and the measurements of those effects by sleep deprivation on one’s performance. This...
Using secondary sources from academic journals, as well as other peer-reviewed materials in the science of sleep medicine, this report outlines how academic performance and physical health is affected by chronic sleep
According to Wilson (2005), sleep deprivation can cause not only traffic accidents, but also medical conditions such as: obesity, type 2 diabetes, metabo...

When looking at human performance, deprivation of sleep is found to be an area much researched, due to its negative emotional effects said to cause a heightening of emotions such as depression, and a decrease in self control along with an increase in hostility (Christian & Ellis, 2011; Barnes & Hollenbeck, 2009). During Dotto’s experiences while deprived of sleep, Dotto was recorded showing negative emotional effects expected of a sleep deprived individual. These effects were the feeling of depression, frustration, irritation and annoyance (Dotto, 2000). It was also recorded that Dotto’s temper seemed to increase throughout the study showing a heightening of emotion correlating with a lack of sleep (Dotto, 2000). Deprivation of sleep is defined
Another reason that causes the negative relationship between sleep deprivation and academic performance is the impact of high-stress level that is caused by sleep deprivation. As mentioned earlier, sleep deprivation could decrease a student’s critical thinking and problem-solving skills. However, it can also make the students feel more stressful. According to the survey conducted in Ball State campus, there are 15 students that often do their homework before they go to bed. 10 students play video games, computer games, and mobile games before they go to sleep. 8 students use their electronic devices to do social activities. 5 students watch movies and television series and 2 students read books before they go to bed. This information proves
This research also intended to find at what level sleep depravation was equivalent to the minimum amount of alcohol concentration considered as hazardous. Moreover, participants were females and males from 30 to 49 years old who belonged to a road transportation company or the army. Participants were measured on seven different tests, which were previously chosen by their sensitivity to the effects of fatigue. The IV presented was fatigue at two different levels, caused by alcohol and lack of sleep. While the DV measured was the performance in the seven fatigue sensitive tests. Researcher operationalized the DV by measuring the scores obtained in the different tasks. In addition, participants had to rate how fatigue and alert they were. Results showed that after 17-19 hors with sleep deprivation, performance scores decreased to equal or lower than a person with the minimum level of alcohol considered hazardous. Furthermore, researchers found that sleep depravation also decreases the alertness of participants, which is an important skill to have when
On example is for older kids who drive themselves to school each day. Being sleep deprived provides drowsiness to the body, leading to slow reaction time and being less alert. This can cause more opportunities for these students to be harmed and cause, or be a part of, car accidents. Whether it is running a red light or falling asleep behind the wheel, they are putting themselves and the people around them in danger. On average, there are about 100,000 car crashes per year due to the cause of drowsiness of the driver behind the wheel 2. This is due to the fact of sleep deprivation, which causes lack of mental awareness of the drivers around them, leading to more car accidents. As stated earlier, the US military uses sleep deprivation as a form of torture. Just like the prisoners, the students get little or no sleep, which in some cases could be called torture. This is so because as they are getting no sleep, their body is not replenishing, causing mental damage to the brain that can last forever. Sleep deprivation’s negative consequences can lead to danger for the victim, themselves, and the people around
Sleep is a vital component in human life. It plays a key role in maintaining adequate physical and mental health as well as improving quality of life. Growth and development is also greatly boosted during sleep in children and adolescents as more growth hormones peak production occurs while sleeping (NIH,2017). Adequate sleep makes the body get sufficient rest and readjust in readiness for the activities of the following day.
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.
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.
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).
The authors and scientists from a different study by the U.S National Library of Medicine National Institutes of Health on long and short-term sleep deprivation state directly that “in certain jobs, people face sleep restriction. Some professions such as health care… require working at night. In such fields, the effect of acute total sleep deprivation (SD) on performance is crucial” (Alhola & Polo-Kantola, Sleep deprivation: Impact on cognitive performance). Depending on their schedule, nurses can often be susceptible to sleep deprivation and are no exception, especially if they are working long hours. The study performed research on how acute and chronic sleep deprivation can affect the brain and how it can slow down or worsen thought process and rationality throughout the day for working adults. The authors also explain that “motor function, rhythm, receptive and expressive speech, and memory ...deteriorated after one night of SD.” (Alhola and Polo-Kantola, Sleep deprivation: Impact on cognitive performance) Although everybody is affected by a lack of sleep differently, some might have the ability to handle it a lot better than others, but it is fair to say that no one can perform their jobs perfectly if their brains are being affected by sleep deprivation. This organization concludes this study by explaining that there is still much research that needs to be
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. In spite of their differences, both articles showed that lack of sleep is a cause for decreased performance and a detriment to a productive and healthy lifestyle.
Sleep is a reversible, repetitive, and active behavior which plays different roles. These roles include restoration processes, memory consolidation, learning or growth. As argued out by Curcio, Ferrara and De Gennaro (2006), during sleep, neuro-cognitive, psychological, as well as behavioral processes take place. Many individuals sacrifice their sleep with an aim of carrying out extra activities. However, sleep loss has been found to have various negative effects. Some of these effects include impairment in psychomotor, neurocognitive performances, and sleepiness (Curcio et al., 2006). Results from recent studies have demonstrated that sleep plays an integral role in memory consideration and learning processes (Deregnaucourt et al., 2005 & Curcio et al., 2006). This paper will evaluate journals and other accredited sources of information in an effort to review, analyze, critique and synthesize works of other scholars on how sleep affects learning.
Preliminary Thesis Statement: Sleep deprivation has detrimental effects on the health and academic performance of students.
