Effects Of Sleep Deprivation On Cognition By William Kilgore

Thesis: Sleep deprivation can lead to serious health problems, make you forget information, and have a negative impact on the outlook of life.

Sleep is a beautiful thing, but people do not get enough of it. It is a time for the body to rejuvenate and process the events of the day. Sleeping is something that we seek out. Getting the recommended amount of sleep allows our body to function properly the next day. Without it, there could be detrimental consequences. The National Institute for Neurological Disorders and Stroke says that without sleep, neurons could be “polluted with byproducts”. In severe cases, people who get very little sleep often experience mood swings, hallucinations and cells do not continue to reproduce.

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

Do not take this study lightly. Sleep is a biological need, it is vital to the human body. Deprivation will not kill anyone directly. However, it will cause personality shifts (irritations, mood swings, microsleeps), hallucinations, and paranoia. Microsleep is temporary sleep that lasts anywhere from 1 second to 30 seconds. An individual becomes unconscious for that time period and fails to process sensory input. Loss of sleep also affects concentration, memory, hunger, weight, and the immune system, all negatively. Studies show that driver fatigue is the cause of 20% of US car accidents. When the clocks ‘spring forward’ in the Spring, more accidents

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.

You may have difficulty thinking clearly in simple tasks. These tasks may include putting a DVD in a player or writing your name. Although they may seem like straightforward undertakings, a person's ability to concentrate is inadequate when sleep is not prioritized. Also sleep deprivation is vital in creating memories. Furthermore, sleep helps with memory and thinking processes. In addition, sleep will cause an altered state of consciousness which will in turn causes fuzziness, disorganization and limited alertness. This results in difficulty paying attention in activities such as driving. Another example of how sleep deprivation negatively effect you life, is the inability to focus on a test. Without sleep your focus and logical thinking would be

Frenda, Patihis, Loftus, Lewis and Fenn’s (2014) article titled “Sleep Deprivation and False Memories sought out to explanation how sleep deprivation can have a role in an individual’s cognitive function. One-way researchers went about unraveling this particular question was to uncover the invisible knowledge relating the formation of false memories with sleep deprivation. Two experiments were executed diving into the many ways that sleep deprivation can affect a person’s thoughts and general decisions, using many examples.

zzzzzz...are you tired? I know I am...of writing this paper! In fact most of the kids in class are probably tired too. Surprisingly, according to WebMD, about 20% of Americans get less than six hours of sleep on average a night (1).With all the hustle and bustle of our daily lives, it is understandable to push sleep off. Harvard University has conducted extensive research, discovering how sleep affects the brain; “given that a single sleepless night can cause people to be irritable and moody the following day, it is conceivable that chronic insufficient sleep may lead to long term mood disorders” (1). Just one night of not sleeping can put one in a bad mood, much less consistent loss of sleep. But how does lack of sleep affect others around us? Sleepiness and sleep deprivation can be accounted for roughly one million car crashes annually in The United States. (Harvard Medical School 1). It is easy to understand that sleep loss is something that affects a majority of the people living in the U.S. and sleep deprivation is something that not only affects us, but affects those around us. Scientists speculate that during the night various sleep cycles playa role on consolidating memories in the mind (Harvard Medical School 3). So knowing that sleep plays such a critical part in the growth and development of our brain, then why do we put it off in order to finish other tasks? And in doing so, what neurological

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

Even though the number of hours differs for different people, the mental and emotional affects damage all. Lack of sleep effects the brain’s

of sleep is seen as an adaptive move to keep humans from wandering in the night. How we sleep? We go from waking to sleeping, then we get a little deeper into our sleep, sleeps spindles generate periods of extreme activity. Then we go deeper and deeper as delta waves come from our brain waves go lower. During REM (Rapid Eye Movement) the brain is hyped, blood pressure increases causing the heart rate to increase in speed. REM is also crucial in the strong ties we have in memories. REM Rebound goes up REM after decreasing it.

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.

“Unexpected Ways Sleep Deprivation Makes Life Tougher” written by Andrea Peterson, the writer for the Wall Street Journal, explained how not having enough sleep can affect your body and your performance. What one does not obtain the correct amount of sleep it can cause short term and long term effects such as long term memory, short term memory, recall and performance in daily life. Sleep deprivation is a problem that is often overlooked in today’s society. This purpose of this article is to inform our society about the side effects of sleep deprivation in hope of influencing one to change their sleeping patterns. If you do not get the appropriate amount of sleep your daily life will become just that much more difficult.

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.

Sleep is one of the key essentials for cognitive performance, yet it is accounted that most people do not receive a sufficient amount. The Center for Disease Control and Prevention reported in 2016 that on average, 50-70 million Americans do not receive the proper amount of sleep per night. This concept is more commonly referred to as sleep deprivation. By definition, sleep deprivation is simply not getting enough or the lack of sleep. As the number of hours that a person is awake increase, their cognitive and attentional deficits become more evident. Prospective memory is remembering to do something that you previously planned to do. This form of memory is often aided by cues in the environment and requires cognitive and attentional capacities. Sleep or the lack thereof can impact numerous processes such as memory, attention, and executive functioning. The main objective of this present study is to examine the effects of sleep deprivation on the attentional networks and cognitive functioning required for prospective memory. The results of this study will provide in depth insight on the importance of an adequate amount of sleep for the successful performance of various cognitive tasks and propose further research.
