The Effects Of Partial Sleep Deprivation On Cognitive Performances

The other half being the effect it has on your athletic performance. We do have to remember here that the whole reason we are “student athletes” is because we are expected to perform on the college level. Which could prove to be difficult if the athlete is sleep deprived or stressed out. Studies from PhD Eve Van Cauter, show that a hormone called cortisol are higher when a person is sleep deprived, which leads to memory impairment, stress and impaired recovery with athletes.

According to the study, athletes are recommended to get 10 hours of sleep a night for faster reaction times and peak athletic performances. If student athletes do not get at least the normal recommended 9 hours of sleep, they are more than likely to make a risky decision that could lead to an injury (Early School Start Time/Athletic Performance, 2013). The researchers asked the player to maintain their normal nighttime schedule which is six to nine hours for two to four weeks and then aim to sleep 10 hours each night for the next five to seven weeks. During this study, players abstained from drinking coffee and alcohol and they were asked to take daytime naps when travel prohibited them from reaching the 10 hours if nighttime sleep. At the end of

This was a very interesting assignment; I have learned some important things on this topic. The topics are on circadian rhythms disorders and sleep deprivation. To start out on circadian rhythms disorders this is what I have learned. Circadian rhythms are regulated by a part of the hypothalamus called the suprachiasmatic nucleus. One’s alertness, core body temperature, moods, learning efficiency, blood pressure, metabolism, and pulse rate all follow these circadian rhythms. Circadian rhythms lead to sleep deprivation. Circadian rhythms affect one’s body not allowing one to get the correct sleep and time of sleep one is need to function properly.

In the present study we sought to characterize abnormalities in sleep architecture and quality, in a cohort of patients with medically refractory versus and controlled epilepsy, versus normal healthy controls and to study the effect of sleep parameters on cognitive function in these groups. The main observations made were of significantly longer self-reported and polysomnographic TST in patients with refractory epilepsy in comparison to controlled epilepsy and healthy controls. Sleep architecture was also found to be markedly disturbed among epilepsy patients in both groups, with prolonged REM latencies, and frequent arousals and awakenings although these abnormalities were statistically similar between the groups. Our main observation is that higher total sleep time has a negative correlation with memory and executive function performance.

Sleep is the most important part of a student-athlete’s life. “Getting your zzz’s may be just as important as fitting in training sessions”(“Find out Why Snoozing”). The fact that sleep is just as important as sports, or maybe even more important really tells something. In order for a person to live a healthy lifestyle, they first need to start out by getting a good night’s sleep. People that receive less than six hours of sleep are in risk of disease, as well as other medical issues. Also a lack of sleep can increase stress levels, which can drive people into depression. “Researchers have also found that newly learned information and skills are reinforced by a good night’s sleep --- meaning that children are becoming better at their soccer footwork, their piano playing, or

The students could rate their current mood on a scale from zero to seven. The higher the

We all know that loss in sleep can lead to negative effects such as fall in mood and mental performance. Its can also affect our normal physiology. The worst is chronically losing sleep because this can be associated with cardiovascular disease, diabetes, and even cancer. Basketball players athletic performance were compared. Those who slept 10 hours every night vs. those who slept 6 to 9 hours showed a faster sprint time, better shooting accuracy, decreased reaction time, and better mood. Other improvements include a higher level of brain activation.

Sleep is essential for optimal human function. In fact, a lack of sleep can actually affect important cognitive functions, like memory. A 2007 study added to the already substantial evidence that even acute total sleep deprivation impairs attentiveness, working memory, and reaction time in various tasks (Alhola, Polo-Kantola). One such way to further this investigation of the effects of sleep deprivation on memory is through the Memory Interference Test, or MIT. MIT is a program designed by Gaston Pfluegl, Ph.D., and Enrique Lopez, Psy. D., at UCLA to test the memory of students. Along with a memory test, the MIT also anonymously collected the physical states, mental states, and demographics of each student test subject, providing a substantial database through which students can test hypotheses, such as the connection between sleep deprivation and memory. Since the MIT requires short-term memory recall, the hours of sleep a student had before taking the test could have a noticeable effect on his or her performance. An unprecedented study this year found that sleep deprivation may actually even induce false memories, which would certainly impact a student taking the MIT because the test requires the subject to recognize images that have been previously presented to them (Frenda, et al). The hypothesis is that students who slept 8 hours before the test will perform better on the MIT than students who only slept 4 hours. The null hypothesis is that students who had adequate

The performance Triad is as it sounds made up of three separate but interchangeable parts that are intended for the military services to utilize to enhance their combat readiness. It consists of Physical Fitness, Nutrition and Sleep and I will quickly explain each aspect to give the reader an understanding of what it is. I will also explain why I believe sleep to be the most crucial and important part of the Performance Triad and lastly looking at ways to implement the Performance Triad for soldiers that are in a field environment.

In the article, “ Sleep Deprivation and False Memories,” by Steven J. Frenda. Lawrence Patihis, Elizabeth F. Lotus, Holly C. Lewis, and Kimberly M. Feen, researcher ’s, from the Department of Psychology and Social Behavior at the University of California, Irvine and Michigan State, did a study on certain factors that affect memories and the creation of false memories. Researchers want to find, within this experiment, how sleep deprivation and memory storage relate to each other. The researchers are looking at the relationship between self-reported sleep duration and false memories and the effect sleep deprivation is susceptibility to false memories. The researchers started off there report by telling what false memories are and where they stem from. False memories are when the encoding process is

A recent news article on CNN, Lack of Sleep May Shrink Your Brain, cites a research study suggesting that insomnia and other reasons for sleep deprivation may reduce brain mass. Although the study was correlational, the author of the news article focuses mostly on one of the three possible relations between sleep and brain mass: lack of sleep may cause shrinking of the brain. Only at the end of article, the author mentions that shrinking of the brain may cause lack of sleep, but completely disregards the third possibility that a third variable may cause both the shrinking of the brain and lack of sleep.

Lastly, the long-term effect and the most common consequences are mood and behavior. Usually, changes in mood and behavior are the first signals and symptoms that show individuals are suffering from sleep deprivation. Before experiencing hallucinations and motor and cognitive impairment, the first symptom that was shown in Gardner’s behavior was mood and behavior change. “Sleep and emotion are closely linked, however, the effects of sleep on socio-emotion task performance have only recently been investigated” (Beattie et al., 2014). People who are usually gentle and soft will become aggressive and depressive, people become sensitive to their surroundings, or individuals feel more irritable, hostile, and angry when they experience sleep loss. According to Kushida (2005), “mood changes commonly include

Unending and intense lack of sleep will adversely effect learning and considering. There is a misfortune consideration and readiness includes a progression of breaches, or eased back reactions prompting waking-state insecurity in a few psychological procedures, for example, working memory. Rest misfortune seems to influence a few parts of comprehension more than others. Case in point, inventive and creative mental handling have all the earmarks of being a great deal all the more contrarily disabled when contrasted with choice making and arranging undertakings other subjective aptitudes depressingly impeded from intense rest misfortune, for example, response time, memory assignments, visual motor errands and thinking abilities.

Sleep deprivation is a common issue among people around the world, and everyone has or will experience it in their life. Not getting enough sleep makes it difficult for the body to function properly. Insomnia is a well-known disorder, mainly known in the United States; one in ten adults suffers from this disorder (Kloc). There are many reasons why people end up with a sleeping disorder, and the most common reason is stress. When people do not have enough sleep they behave differently, and do not make the same choices as if they were fully rested. There are four stages of sleep. The fourth stage, REM (Rapid Eye Movement) sleep is the most important stage of sleeping. A common side effect of BPD (Borderline Personality Disorder) is sleep

Everyone has done it before: putting off studying for that exam until the last minute, then pulling out the caffeine for an all-nighter to cram as much information into their heads as they can. Cramming is the act of taking in massive amount of information in a short period of time just before an examination.When we cram for exams, the causes are usually because we lose interest in studying, have another large pile of work to worry about, or plainly play around too much – not being serious. However, there are consequences for cramming late at night. Harvard Medical School associate professor Seung-Schik Yoo’s research suggests that “lack of sleep impairs mental function [and] leaves students vulnerable to long-term permanent damage”
