Sleep Deprivation And Its Effects

Total sleep deprivation longer than forty hours proves impossible; however, due to brief periods of micro sleep, it is possible to function properly longer (“Sleep”). Micro sleep represents the body's obvious need for sleep. Even though it only lasts for a couple of seconds, it can have some restorative function to the body, but individuals cannot survive on this; they need a full night’s rest (“Sleep”). Losing more than one night's sleep produces a noticeable increase in irritability, lethargy, disinterest, and even paranoia. An individual’s psychomotor performance and concentration are also affected and eventually immunological functions suffer. Newborns sleep as many as seventeen hours a day, whereas five-year-olds average about twelve hours a night (“Sleep and Sleep Disorders”). For some reason, many people experience the best and most satisfying sleep of their lives during the middle teen years (“Sleep and Sleep

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

The function of sleep is to promote restoration. The human body accumulates damages due to impact strain and from reactive oxygen species that damage cells and buildup during times of activity (Sleep-wake cycle, 2006). During sleep, most of the body's systems are in an anabolic state, helping to restore the immune, nervous, skeletal, and muscular systems (Sleep-wake cycle, 2006). Most of the body has restorative processes that can supplement the restorative processes that happen during sleep for long periods of time, but the brain is more reliant on regular intervals of sleep for restoration as quiescent restoration is insufficient (Sleep-wake cycle, 2006). When the body does not get enough sleep, most body functions work at diminished capacity. (Brain Basics, 2017). Sleep deprivation is defined as obtaining inadequate sleep to support adequate daytime alertness (Kryger, Roth, & Dement, 2005). The pathological effects of sleep deprivation can lead to undesirable physiologic

Sleep duration and quality participate in normal metabolism, function of immune system, mood, and cognitive functioning [1]. Short duration of sleep and circadian misalignment are hypothesized to contribute to many problems of health including over weight, diabetes, metabolic syndrome, cardiac disease, mood disorders, cognitive dysfunction, and

The relevance of sleep to the human body cannot be over emphasised. From this study we can learn that sleep is important and with out it we could not properly function in our day to day lives. Sleep deprivation studies has taught as these important factors.

Sleep is undeniably a necessity for humans and other animals alike. At the beginning of each day, our bodies awake like clockwork in conjunction with the rising sun. Then, at day’s end, they begin to wind down into sleep until the morning. While there certainly may be plenty of mysteries revolving sleep that have yet to been unraveled, from all the way up until now and for centuries to come, it is evident that sleep should hold priority in the schedules of all people. Yet, despite all of this being true, sleep is consistently being taken for granted. And, it is not an overgeneralization to say that many people have, at least once, trudged through a late night as many people have. Even to the point of the night no longer being considered “a

Sleep fragmentation or interruption is a result of many common disorders such as sleep apnea, restless leg syndrome, depression, and post-traumatic stress disorder. Rats in this experiment are wakened every two minutes by turning on a slow-moving treadmill for thirty seconds. As seen in this experiment, while sleep fragmentation does not affect NREM sleep, it interrupts normal sleep by reducing REM sleep, and thus its respective restoring benefits. Spatial mapping by the hippocampus will be tested after 24-hour periods of sleep interruption by observing rats in the Morris water maze.

To find out how sleep deprivation affects humans, Dement (1960) connected participants of his study to an electroencephalogram in his sleep laboratory. The participant got woken up any time they showed signs of entering REM sleep. I was found that REM sleep deprivation made test participants more aggressive and suffered from poor concentration than the control group. They also tried to enter REM sleep straight after going to sleep. They made 26 attempts to enter REM sleep by the seventh night. It is to conclude that REM sleep is necessary for proper brain functioning as the brain goes into REM rebound, when deprived of

Sleep deprivation is a phenomena which has been extensively studied on its own, but the effects of sleep deprivation on cognition and working memory in particular have been an area of interest to a lot of researchers. The research done on this topic has collectively found that sleep deprivation has detrimental affects on cognition. Studies such as the experiment conducted by Joo, Yoon, Koo, Kim, and Hong in 2012 outline how sleep deprivation can result in deficits in cognition. The study explored how 24 hours of wakefulness affects cognitive functioning and stress hormones (Joo, Yoon, Koo, Kim, & Hong, 2012). In this study participants underwent electroencephalographic monitoring while performing a test which consisted of responding

 Many benefits are emerging of sleep on cognition and health, supporting the importance of sleep on waking state functioning. From a cognitive perspective, sleep has been implied in for example improving memory consolidation, supporting future memory encoding and generating sleep-related insights over waking state problems (Talamini, Nieuwenhuis, Takashima, & Jensen, 2008; Van Der Werf et al., 2009; Wagner, Gais, Haider, Verleger, & Born, 2004). From a health perspective, sleep has been linked to improved immune system, metabolism and endocrine functioning and better cardiovascular health (Dinges, Douglas, Hamarman, Zaugg, & Kapoor, 1995; Spiegel, Leproult, & Van Cauter, 1999; Knutson, 2010). The discernible

Sleep deprivation comes with many risks such as impaired cognitive performance, behavioral changes, and health issues. This paper will review research on sleep deprivation and inadequate sleeping patterns such as napping to make up for loss of sleep. This paper will explain the normal sleeping patterns that one

This human subject research was conducted in 2002 by Amy Martin, Christine Davis and Young-Mi Oh from Department of Zoology, North Carolina State University, which its grounds is to analyze the effects of total sleep deprivation on basic vital signs and cognitive functions.

The amount of sleep varies with each individual and there are many factors that affects this such as age, lifestyle, environment and health. However, the recommended number of hours for the average adult is between seven to nine hours. To remain unconscious for approximately a third of one’s life suggests that sleep must serve some crucial function, especially when considering the evolutionary viewpoint that to be less responsive to potentially threatening external stimuli (e.g. predators) for such prolonged periods of time has been conserved across all animal species despite being counter-intuitive and a danger to survival.

Bradley Youngblood, Jun Zhou, Gennady Smagin, Donna Ryan and Ruth Harris (1997) conducted a study entitled Sleep Deprivation by the “Flower Pot” Technique and Spatial Reference Memory. In this study, they put rats in a Morris water maze and test how long it took for them to reach the platform. However, after day one they were sleep deprived by being placed on a platform above water so if they lost muscle control, by trying to fall asleep, they would fall in the water. From trial one to trial four the time to find the platform, in the Morris water maze, doubled. This study concluded that sleep deprivation caused memory impairments.

The survey data and collected research presented in the product will be beneficial to anyone unaware of the effects of sleep deprivation. The product is an organized way of providing information on the topic, and it is easy to read and understand the basic facts about the subject. The researcher could continue the topic in future projects, by either expanding the
