The Effects Of Performance Impairment Caused By Sleep Loss

With regard to sleepiness, several studies indicated that the average of sleep duration in 1910 to 2002 have decreased from 9 to 6 hours on workdays (National sleep foundation, 2002; Groger et al., 2004). Recently, a survey study of Roger et al. (2004) shows that an American Nurses have an average of 84 minutes more sleep on non workdays. Thus, shift work suggested as a cause of sleeping disorder among nurses where they feel of sleep during the shift. Considering the contributing factors of sleepiness, the literature identified that long working hours and rotating shifts are causing sleeping disorder. In the night and rotating shifts, the nurses are rarely obtained adequate amount of sleep. In fact, the nurses experiencing less sleeping hours (1 to 4 hour) than normal sleeping (Zeisler et al.,1980). Nevertheless, insufficient sleep is a significant reason of damaging planning, decision-making, and integration of information (Krueger, 1994; Harrison and Horne, 2000). More recent studies have revealed that long hour shifts and overtime are strongly linked to the difficulties of being a wake through the shift which leads to increase the risk of making an error (Scott et al., 2006; Roger et al., 2004).

In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep

As a college student, the information David Randall presents is very intriguing due to the fact that most of us are sleep deprived due to late night studying, among other things. It is very evident that Randall relies on statistics to build and progress his argument. He tells us how over time certain statistics have increases and by how much. This opens our eyes and makes us realize that there really is an issue. By providing these sources Randall becomes trustworthy and our doubt of whether this is true or not are put to rest. The author comes into contact with our feels once he brings in true stories to the picture. He informs us of the incidents that have occurred due to sleep deprivation. At this point the issue becomes more than a statistical

Sleep deprivation is a serious concern among college students, who are "among the most sleep-deprived age group in the United States," (Central Michigan University, 2008). It is important to study the causes of sleep deprivation, or sleep disorders, among college students. According to Park (2009), "dozens of studies have linked an increase in nightly sleep to better cognition and alertness." A study by Central Michigan University (2008) found that sleep deprivation can lead to poor academic performance, impaired driving, depression, and behavioral problems. There are several variables that may affect sleeping patterns among college students. One is genetics or biological issues. It is highly

This essay focuses on evaluating three functions of sleep. These functions include mental health (Jackowska et al, 2011), cardiovascular disease (Kronholm et al, 2011) and memory (Hu et al, 2006). The key aspects are explained in detail with regards to studies. The findings from the studies will help justify the function and it’s involvement with sleep. Sleep is important for an individual’s well being, survival, brain development, emotional regulation, cognitive function, memory, and in order to protect mental and cardiovascular health. An individual should sleep for 6-8 hours. A recent suggestion by the American Academy of Sleep Medicine recommended that an individual should sleep for minimum 7 hours. The quality of sleep is significant to maintain healthy brain functions. Evidence, indicating that good sleep quality is essential for mood and health then duration (Chandola et al, 2010). The researches implied will enable the understanding of the functions of sleep and evaluate the evidence of each of the functions, including advantages and limitations. Furthermore ethical issues are discussed, and an overall summary of the essay is briefed.

or illness.(Warren, 2008) Warren reports as little as one hour of sleep loss daily, can accumulate and result in decreases in attention span, reaction time, and problem solving

Success in life is typically measured by the result of what is accomplished during the waking hours. The degree of effectiveness of those hours however, depend on effective rest. “Sleep is integral to the health and well-being of all people” (Wells 233). Sleep is simply defined as the body’s rest cycle – a time to recharge. The widely accepted metric for normal or sufficient sleep is about 8 hours of uninterrupted sleep. When this metric is not met, either through total sleep loss or accumulated sleep debt, the effect can be dire, “Sleep deprivation results in poor memorizing, schematic thinking, which yields wrong decisions, and emotional disturbances such as deteriorated interpersonal responses and increased aggressiveness” (Orzeł-Gryglewska 95). Sleep deprivation hinders the abilities of the mind, harms the body, and shortens length of life.

An emerging area of research has begun to focus on recovery processes from acute total sleep deprivation and chronic sleep restriction. Results from these studies suggest that recovery process may be slower and more complex than originally thought. Recovery appears to be affected by the type (acute versus chronic) and severity of sleep loss, recovery sleep duration and the number of days allowed for recovery and aspects of neurobehavioral functioning appear to recover at different rates. Additionally while an individual may report feeling recovered, their performance may remain impaired increasing risk for accidents and injury. It is therefore critically important to understand how much sleep people need to recover from periods of sleep loss.

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 effects of long work hours, resulting in insufficient sleep have been well documented (Rogers, 2008). Insufficient sleep alone has been noted to cause cognitive problems, mood alterations, reduced job performance, reduced motivation, increased safety risks, and physiological changes (Rogers, 2008). Failure to obtain a sufficient amount of sleep is even an important contributor to medical errors (Rogers, 2008). Now think of the effects of sleep, and add in stressful work environments, short-staffing, pressure from administration, and unexpected events, we can begin to realize how patient outcomes may be greatly compromised.

Weaver from Oklahoma State University. According to the authors “the purpose of the present study was to determine if sleep deprivation and/or poor sleep quality in a sample of non-depressed university students was associated with lower academic performance” (Gilbert, Cameron. 295). The study was also made to determine the relationship between sleep deprivation, sleep quality, and academic performance (Gilbert, Cameron. 298). It was hypothesized that by the end of the study, participants who had higher levels of sleep deprivation and poorer sleep quality would have lower academic performance (as indicated by grade point average [GPA] and course incompletions—drops, withdrawals, and incompletes) than participants with little sleep deprivation and good sleep quality (Gilbert, Cameron. 298). By the end of the study, the authors discussed the results in the following narration:

What do the effects of sleep deprivation have on people? When a person does not get enough sleep, he or she is depriving his or her body of something that it needs. A delightful sleep is one of the most satisfying human experiences with a role to play in supporting a good mood and cognitive acuity as well as in promoting physiologic balance and resilience (Chittora, Jain and Suhalka). People think because they get an insufficient number of hours of sleep, they will not have an emotional impact by it. Sleep is a required need for peoples’ day to day life to be able to perform and stay healthy emotionally and physically. The effects of sleep deprivation are an issue because it affects mood, performance, and health.

Specific Purpose: To inform my audience about the factors contributing to sleep deprivation and the effects of insufficient sleep.

The term ‘Shift work’ is usually referred to uniformly divided allocations of the day in which individuals participate alternatively to provide twenty four hour coverage. A shift in sleep schedule conflicts with the body’s natural clock also known as the circadian rhythm into interpreting the time as ‘inappropriate’ and disrupts the homeostatic regulation cycle resulting in poor health outcomes. Fortunately, it is deemed possible to counter unfavourable effects of alternating insomnia and sleepiness through certain practices.
