Free education EssayWhen Thomas Edison set erupt to create the strike bulb, his intention was to reduce the amount of time that people spent tranquillitying. His idea was that if people had light to achievement by they could and would work longer hours. In his mind, sleep was something that was non needed and stood opposed to progress (Coren, 1996). Anything which tends to speech little(prenominal) work down is a waste. We ar al styluss hearing people talk about freeing of sleep as a calamity. They better call it loss of time, vitality, and opportunity. -Thomas Edison Even great minds, like Edisons, elicit be wrong at times.Some researchers argue that had Edison spent more time sleeping it would not energise taken him more than 1000 attempts to create his light bulb. Research has shown that neglect of sleep deal have adverse effects on an case-by-cases visible health, mental health, and productivity. The information presented in this paper will address the import ance of sleep in military man health, safety, and productivity. First, some physical issues attributed to sleep deprivation will be discussed. Next, mental problems link up to lack of sleep with be outlined with attested cases.Lastly, examples of errors and disasters that have been tied to sleep deprivation will be presented. There are legion(predicate) physical issues that are linked to sleep deprivation. Cardiovascular problems and greater risk of death have been tied to lack of sleep. The homosexual body requires sleep to ready and repair itself. When the body does not get the rest it requires the consequences afterwards part be quite unfortunate. Poor sleep has been shown to increase the risk of high blood pressure, eye failure, stroke, and heart attack.The homo liver produces a protein called C-reactive protein that is used by the body to aid in response to inflammation, injury, or infection and is removed by the body when the inflammation, injury, or infection is gone or heals. This protein binds to damaged cells, as well as some bacteria, to aid in removing them from the body. This allows the body to heal. One study showed that over a period of five days during which a subject was denied sleep, the C-reactive protein builds up in blood at a steady and signifi female genitaliat rate. peacefulnessing allows the body time to process and remove these proteins.An increase of these proteins can at times lead to heart attack, stroke, or high blood pressure (Meier-Ewert , Ridker , Rifai, Regan, Price, Dinges Mullington, 2004). The body is able to restore itself and heal when given between six and eight hours of sleep in a 24-hour period. While a person sleeps the immune system is working to restore and revive the body. When the human body is not given enough sleep, the immune system is not able to fully complete the task of taking solicitude of and healing the body. Lack of sleep can also cause the number of T-cells to decline in the human body.T- cells aid in immunity and assist other cells in their functions. Lower T-cell levels mean that the body is less able to fight off infection, subdue inflammation, or heal an injury (Mann, 2010). When the body is unable to heal itself, there is greater risk of death. Sleep deprivation can also lead to an increase of stress, which has been linked to heart disease, obesity, depression, gastrointestinal issues, as well as mental heath issues. Allowing the body to rest and fix during sleep helps ensure that many physical issues associated with the lack of sleep can be avoided.Another way that lack of sleep increases the chance of early death is in traffic accidents. The National Highway art Safety Administration gives a conservative estimate that 100,000 reported crashes per year are a conduce of a fatigued driver (Facts and stats 2012). Mental illness has also been linked to lack of sleep. Issues ranging from poor concentration, softness to focus, retention loss, the appearance of p sychosis, and diagnosed mental disorders have been attributed to sleep deprivation. In the past, researchers believed that poor sleep was caused by psychiatric problems.However, recent research is showing that a lack of sleep is usually the catalyst of mental disorders. When the human body needs to concentrate or focus when it has not had enough sleep, it produces hormones adrenaline and cortisol in an attempt to engage and wake itself up. These hormones give the body a short-term boost in cipher and they affect the body in much the same way that caffeine does. Once the boost in energy is finished, the body often crashes and a person returns to feeling tired unable to concentrate or focus again.These hormones, again like caffeine, often make a person feel jittery of jumpy, which whitethorn impede concentration and focus. These hormones have also been directly linked to increase stress in the human body (Hart, 1985). Memory loss can also be a result of sleep deprivation. Memories ar e captured and recalled in the brain by a three-step process. The first step in creating memories is acquisition where a person has their first experience with what will become the memory. The next is consolidation which occurs while a person sleeps. In this step a memory becomes stable in a persons brain.Recall, the final step, is the ability to entre the memory in the future. When the brain is denied the opportunity to stabilize a memory during sleep, a person is much less likely to retain the memory (Chang, 2011). Studies have also shown that disciples who study regularly and get a well behaved night sleep before exams generally do better than students who cram the night before. The information that the student needs is better solidified in the brain and is ready for recall when the student needs to access the information (Sifferlin, Augu). Symptoms of psychosis have also been directly tied to sleep deprivation.In at least both documented cases, persons who went without slee p for extended periods of time showed symptoms similar to psychosis. In 1964 Randy Gardner attempted to gain entry into the Guiness Book of Work Records by staying awake for eleven days (264 hours). Gardner suffered a gamut of symptoms. Days two through with(predicate) five found Gardner unable to concentrate, irritable, unwilling to cooperate with others, and hallucinating. During days six through nine Gardners speech slowed, his irritability increased, and he began to have lapses in his memory.He often would begin sentences without finishing them and he had difficulty recalling the names of common objects. Paranoia began to set in on day ten. On day eleven, Gardners speech was slurred and without intonation. He seemed expressionless and had to be encouraged to talk or respond to soulfulness talking to him (Ross, 1965). A similar story is told of Peter Tripp, a disk jockey from New York. In an effort to raise money for the March of Dimes, Tripp stayed awake for 200 hours. He show ed many of the same symptoms that Gardner did. Tripps experience with sleep deprivation ended with him mistaking a doctor for an undertaker.He charged out of the room with doctors following close behind. Tripps mind could no longer determine what was real and what was not (Ross, 1965). With the aid of doctors, Randy Gardner was able to recover completely from his psychotic episode. He was monitored while he slept and in conclusion returned to normal sleep patterns and a normal state of mind. Peter Tripp, however, suffered from his self-inflicted psychotic break. For some time after his sleepless stunt he thought that he was an impostor of himself and complained of headaches and emotional instability.Lack of sleep can also affect how people perform at their jobs. Routine and remedial tasks are often change by a lack of sleep. Simple errors, such as spelling, grammatical, mathematical, or clerical errors are more or less often made due to a lack of sleep. These errors can either go unnoticed or can be corrected without significant consequence. More significant errors are also attributed to fatigue. Between 50,000 and 100,000 deaths from each one year are caused by preventable medical errors.Long shifts for doctors, interns, and nurses deny medical professionals sleep take for them to function a highlevels. The nuclear accident at Three Mile Island, the meltdown at Chernobyl, the grounding of the Exxon Valdez, and the explosion of space shuttle Challenger have all been linked to fatigue (Harris, Horne, 2000). Sleep deprivation is bad for your brain when you are trying to do high-level thinking tasks. It may have unspoilt consequences both on performance and on the way your brain functions. -J. Christian Gillin, M. D. (DeNoon, 2000) In research and in experience it has been proven that lack of sleep can have adverse effects on an idiosyncratics physical health, mental health, and productivity.An individuals physical health is affected by sleep deprivation by an increased risk of death, cardiovascular problems, and issues with their immune system. A persons mental health suffers as well from a lack of sleep. Memory loss, inability to concentrate or focus, and even psychotic episodes have been traced to sleep deprivation. Randy Gardner and Peter Tripp are prime examples of what happens to the brain when it goes without sleep. Poor job performance and errors ranging from undistinguished to catastrophic have been linked to a lack of sleep. The amount of sleep needed for each individual is different.Where some people are able to function on very little sleep, others need many hours to fully restore and rejuvenate. References Coren, S.
