...Physical effects of Sleep Deprivation According to numerous studies, the optimum amount of sleep a person should get each night is seven to eight hours. A lot of people have trouble getting the right amount of sleep, especially college students. Between schoolwork, household chores and extracurricular activities, most of the time a person gets only a few hours of sleep at night. “Most of the physical side effects from sleep deprivation are relatively minor and, thankfully, easily reversible. And the cure? Get some sleep. If you do not sleep enough, you may be faced with myriad consequences.” So what are these consequences? (Peters, B., 2011) The first thing you may notice will be the increased sensitivity to pain. Studies have shown our sensitivity to heat and pressure pain is especially enhanced when we don’t sleep enough. Also, there is reported to be an increased sensitivity to pain in our esophagus, as might occur in the setting of nighttime heartburn or gastroesophageal reflux disease (GERD). (Kryger, M., 2011) Pain disturbs sleep by inducing arousal and triggering all other neurobiological sequels of stress, which are incompatible with an undisturbed sleep. Accordingly, sufficient management of disturbed sleep might alleviate pain. On the other hand, better pain relief may promote more restorative sleep, which then further assists in long-term pain relief. (Lautenbacher, S., Kaunderman , B., & Krieg, J., 2006) Second, will be the change in your vital signs...

Maneceine in 1894 on rats by depriving them of sleep and examining their behavior. Sleep deprivation is an important part of academic life. It is often quoted “a sound mind in a sound body” to describe the ideal and desirable state of a human being. It can be observed that the functioning of a ‘sound body’ is vital to the efficient working of a ‘sound mind’. To maintain a healthy body it important that the recuperative functions of the body are allowed to efficiently play their role. The...

...of the brain, thus stimulating various functions, such as body temperature, hormone secretion, changes in blood pressure, etc. There are numerous external factors as well, that regulate a circadian rhythm among human beings. These external factors are called zeitgebers (Hawkins & Orlady, 1993). Most common zeitgebers are light and temperature. Others include meal times, various social and physical activities. The most common circadian rhythm known to mankind is the sleep cycle. Sleep is an extremely important physiological phenomenon, during which our body heals and recuperates. Let us begin with understanding what sleep is, and what are the various sleep patterns. Sleep is a revocable state, which is characterized by disconnection and unresponsiveness to the outside environment with closed eyes, reduced movements and recumbency (Smith, Comella, & Hogl, 2008). Normal sleep pattern is classified into two characteristic divisions: Non Rapid Eye Movement (NREM) and Rapid Eye Movement (REM) sleep. These sleep stages are defined by neurophysiological...

Researchers interpreted this result as indicating that the brain of the average sleep-deprived subject had to work harder than that of the average non-sleep-deprived subject to accomplish a given task, and from this indication they inferred the conclusion the brains of sleep-deprived subjects were attempting to compensate for adverse effects caused by sleep deprivation. The temporal lobe, which is a brain region involved in language processing, was activated during verbal learning in rested subjects but not in sleep-deprived subjects. The parietal lobe, not activated in rested subjects during the verbal exercise, was more...

...restless mind: Effects of sleep deprivation on mind wandering. This article focuses on the effects that sleep deprivation can have on the mind, and behavioral changes. Mind wandering, according to the article, results in disengagement of attention from the environment leading to reduced sensitivity to external inputs. Mind wandering has been linked to poor behavior outcomes in tasks that are very simple, and has also been linked to hindering more complex things such as reading comprehension (Jia-Hou Po, Pearlynn L. H. Chong, and Michael W. L. Chee 2016). In previous studies, the link between sleep deprivation and mind wandering has been inconclusive, with some studies showing no...

...Effect of creatine supplementation and sleep deprivation, with mild exercise, on cognitive and psychomotor performance, mood state, and plasma concentrations of catecholamines and cortisol. McMorris T, Harris RC, Swain J, Corbett J, Collard K, Dyson RJ, Dye L, Hodgson C, Draper N. Source Centre for Sports Science and Medicine, University College Chichester, College Lane, Chichester, West Sussex PO19 6PE, UK. t.mcmorris@ucc.ac.uk Abstract RATIONALE: Sleep deprivation has a negative effect on cognitive and psychomotor performance and mood state, partially due to decreases in creatine levels in the brain. Therefore, creatine supplementation should lessen the negative effects of sleep deprivation. OBJECTIVES: The objective of this study was to examine the effect of creatine supplementation and sleep deprivation, with mild exercise, on cognitive and psychomotor performance, mood state, and plasma concentrations of catecholamines and cortisol. METHOD: Subjects were divided into a creatine group (n=10) and a placebo group (n=9). They took 5 g of creatine monohydrate or a placebo, dependent on their group, four times a time a day for 7 days, immediately prior to the experiment. The study was double blind. Subjects undertook tests of random movement generation (RMG), verbal and spatial recall, choice reaction time, static balance and mood state pre-test (0 h), after 6, 12 and 24 h of sleep deprivation, with intermittent exercise. They were tested for plasma concentrations of...

...Speech for Students’ Chronic Sleep Deprivation Introduction: A. Attention Getting Opening: Over the past ten to twenty years, academic demands placed upon college students have increased significantly, this has lead to an increase in workload and amount of time needed to study for a specific course. Today, college students represent the most sleep-deprived division of the population in the U.S. ("Sleep and Memory"). According to Gayla Martindale, 63% percent of the students who attend college do not get enough sleep, which in turns causes 15% percent of these students to fall asleep during class. Sleep deprivation has become a serious problem in the life of students that leads to physiological and psychological impairments, instigates the use of stimulants, and has a negative effect upon the student’s grade point average. B. Reason audience will be interested in this speech: The purpose of this report is to present research on the physiological and psychological effects of sleep deprivation and stimulants on college students and to recommend, based on the overwhelming evidence that sleep deprivation has negative consequences, that New Mexico State University ban the scheduling of any classes before 9am. Sleep deprivation is a serious problem resulting from an increase in academic demands placed upon college students. Loss of sleep leads to physiological and psychological impairments, instigates the use of stimulants, and has negative effects upon the student’s grade point...

...Background of the Study Sleep is a physiological need. It is a way to rest our body from fatigue. Hence, adequate sleep is a biological necessity, not a luxury, for the normal functioning of humans. Good mental and physical health depends on maintenance of adequate sleep. College experience is of great value in providing emerging adults with a structured environment in which they can gain knowledge, skills and independence to chart their own path, become successfully employed and contribute to society. For most students, the college environment is full of new living and social experiences, new freedom from parental supervision and new academic demands. In this situations, most often than not, adequate sleep is neglected. According to poll conducted by the National Sleep Foundation (2000) potential obstacle to maximizing success in college is the high prevalence of daytime sleepiness, sleep deprivation, sleep disturbances and irregular sleep schedules among college students. Daytime sleepiness is a major problem, exhibited by 50% of college students compared to 36% of adolescents and adults. At least 3 days a week, 60% of college students report that they are dragging, tired and sleepy. Sleep deprivation is defined as obtaining inadequate sleep to support adequate daytime alertness. How much sleep a young adult needs is known to be eight (8) hours. Most college students are sleep deprived, as 70.6% of students report obtaining less than 8 hours of sleep. Sleepiness is defined...

...the text’s web site (chapter 9) entitled “Lack of sleep ages body’s systems.” The basic claim of the article is that sleep deprivation has various harmful effects on the body. The reported effects include decreased ability to metabolize glucose (similar to what occurs in diabetes) and increased levels of cortisol (a stress hormone involved in memory and regulation of blood sugar levels). The article also briefly alludes (in the quote at the bottom of page 1) to unspecified changes in brain and immune functioning with sleep deprivation. Intuitively, these results make a lot of sense to me. I know that when I’m sleep deprived for any significant amount of time, I begin to feel physically miserable. I also seem to be more vulnerable to colds and other physical ailments. In thinking about it though, most of the times I’m sleep deprived are also periods of psychological stress (such as finals week). To the extent that there are changes in my physical well-being, I’m wondering whether they are due to the sleep deprivation, the stress itself, or some combination of the two. In principle, a careful experiment should be able to isolate the effects of sleep deprivation by depriving people of sleep in the absence of stress and other such confounding variables. That seems to be what this experiment does, but as I read the article closely, I found myself unsure that the effects it reports are necessarily due to sleep deprivation per se. I realize that a brief summary article...

...Name: Pham Tra My ID: 442329 Topic: Sleep Deprivation Sleep deprivation is getting familiar with a lot of people in the modern world due to numerous problems including the huge amount of work people have to do contrast with the little amount of time they have to complete it. So in an effort to find the best way to deal with it, I want to take a deeper look on the sleep deprivation as well as its consequences, in order to be aware of its effects and make some recommendations for future growth. Sleep deprivation is defined as the condition of not having enough sleep (Wikipedia). There are two main types of sleep deprivation based on their essences: acuteness and chronicity. Acute sleep deprivation includes complete deprivation, partial deprivation and selective deprivation. Complete deprivation occurs when people do not sleep for a period of time or day. Partial deprivation, or sleep restriction, happens more often than complete deprivation when people sleep less than normal over a period of time. Selective deprivation appears when individuals continuously lose their REM sleep. Chronic deprivation is well-known for a more familiar name “Insomnia”. Insomnia is used to refer to “chronic problems in getting adequate sleep” (Psychology: Themes and Variations, pg.144-145). Sleep is acknowledged as one of the most important processes to keep people alive and do things normally. Sleep deprivation lead to so many unworthy problems from which people will have to suffer. They affect...

...Sleep is a necessary part of life. Without it, the brains normal functions can become slow, confused, or cease all together. Situations may arise often where deficient amounts of sleep are considered an acceptable byproduct of an alternative activity. For instance, a man who decides to go out with friends and close down a dance club knowing he needs to wake up at 5:00 am the next morning for work may find he did not receive an adequate amount of sleep to function at the best of his ability the following work day. On the other hand, intentional sleep deprivation, due to the impact it causes on the effected person, was often used to torture prisoners of war. The term sleep deprivation is used to describe a period of time where there is a complete absence of sleep or when one is not able to sleep for the optimal length of time. According to Orzeł-Gryglewska (2010): The clinical symptoms of sleep deprivation include longer reaction time, distractedness, disturbances in attention and concentration, forgetting known facts, difficulty in memorizing new information, and making mistakes and omissions. A higher level of stress is observed; tiredness, drowsiness and irritability increases; work effectiveness decreases and motivation usually falls down (p. 96). One’s judgment and ability to effectively reason may also be affected. Increased irritability may cause the subject to snap at loved ones or coworkers uncharacteristically. Cognitive changes may present after prolonged reductions...

...definition of terms. Background of the Study Sleep is an integrated part of human health and life and is crucial for learning, performance, and physical and mental health. Sleep deprivation is a serious problem facing individuals in many critical societal roles. It is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain. It adversely affects the brain and cognitive function. Few studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction. Complete absence of sleep over long periods is impossible for humans to achieve (unless they suffer from fatal familial insomnia); brief micro sleeps cannot be avoided. A National Sleep Foundation survey found that college/university-aged students get an average of 6.7 hours of sleep each night. Sleep deprivation is common in first year college students as they adjust to the stress and social activities of college life. A study performed by the Department of Psychology at the National Chung Cheng University in Taiwan concluded that freshmen received the shortest amount of sleep during the week. In 1997 the University of Minnesota did research that compared students who went to school at 7:15 am and those who went to school at 8:40 am. They found that students who went to school at 8:40 got higher grades and more sleep on weekday nights. One in four U.S. high school...

...Sleep Deprivation in the Cockpit Abstract Sleep deprivation has been noted as the primary factor of numerous accidents and near mid-air crashes in the aviation industry for centuries. Pilot’s tend to experience sleep deprivation more frequently than the average human being does, this is due to the long hours of international flights or because of coast to coast type flights. Therefore, establishing an understanding of how sleep deprivation influences a pilot’s performance in the cockpit or an air traffic controller’s judgment is crucial in order to counter fatigue or to develop a strategy to eliminate sleep deprivation all together. The goal of this study will help examine the cause of sleep deprivation as well as focus on techniques that will decrease the chances of sleep deprivation in the cockpit. Sleep deprivation is a common particular occurrence in the aviation community for a variety of reasons. Long-haul flight operations often involve rapid multiple time-zone changes, sleep disturbances, circadian disruptions, and long irregular work schedules. These factors can result in fatigue, cumulative sleep loss, decreases alertness, and decreased performance in long-haul flight crews. Therefore causing operational effectiveness and safety maybe compromised because of pilot and crew fatigue (Crew Factors in Flight Ops). According to the National Transportation Safety...
