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 is essential for our health and wellbeing. It allows our body to rejuvenate and restore itself. It helps the body to create new cells. Sleep deprivation is one of the biggest causes of premature aging. Tiredness can significantly affect your mood and how you feel. Sleep can help lower blood pressure and elevated levels of stress hormones. Your cardiovascular system is constantly under pressure and sleep helps to reduce the levels of stress and inflammation in your body. High levels of "inflammatory markers" are linked to heart disease and strokes. Sleep can also help keep blood pressure and cholesterol levels (which
E.) Sleep is important for your physical self as well; sleep deficiency can place a person at risk for obesity. Obesity can additionally place a person at risk for other illnesses such as heart disease, hypertension, diabetes, and stroke.
In the article from LA Times “Sleep Deprivation Has Genetic Consequences Study Finds,” Eryn Brown claims that not sleeping enough can be unsafe for our health. Brown says sleep deprivation shuts down genes that heal the body, which means the body can’t heal itself and leads to disease. She supports her claim by citing expert opinions from epidemiologists, then biologist say that people who don’t get enough sleep, create more stress hormones, and finally researches also had some test done. Brown is writing in a informative tone for the general public readers of LA Times.“Epidemiologists noticed that people who work early in the morning or late at night or who lack sleep in general-have higher rates of diabetes, stroke and high blood pressure, among other ailments,” (5).“Biologist have discovered that people that get poor sleep produce
By reading this article I was able to answer my initial question that inquired how does sleep effect the body? In my eyes, this article is a reliable source because it was published by a M.D. on the Harvard Medical School website. Not only do I feel as if the website is reliable, but the information that is provided makes sense. The information was not all over the place and followed the previous topic in an order that flowed. While reading
In the article from LA Times “Sleep Deprivation has genetic consequences Study Finds” Eryn Brown discusses that being chronically sleep deprived can be hazardous to health. Brown says that since the studies conducted by the scientists disciplining the amount of sleep and how the brain reacts to it.Each report differed and damaged cells activated suddenly when meaning sleeping less can cause hazards for our health. She supports her claim by using various types of quotes, then by using textual evidence , and finally using the results that were manipulated by the scientific experiments. Brown writes it in a candid tone for the general public readers of LA Times. She references it by referencing every source she got it from, and the details of the studies conducted by the scientists In order to inform how sleep deprivation is harmful, Brown emphasizes the experiments used for adults on their brainwave signals. For example, “healthy adults...brain waves scans showed they slept” Brown is effective in informing her readers about sleep
Carol Everson first recorded the affects of lack of sleep in 1989 based on work with rats. Her findings showed that all the mice that were deprived of sleep died within a month. She also showed that sleep does not need to be deprived entirely to be deadly, the deprivation of deep sleep (rapid eye movement or REM) would also cause the rats to die. In Italy, a case had been recorded of a man dying within a few months of developing familial insomnia. In his case, an autopsy was performed on his brain after death and neuron deterioration in the thalamus was found. They did not determine if the deterioration had caused his insomnia or his death. However, the cause of the deterioration was found, and that cause was linked to prions which cause spongy deterioration in the brain. While prions causing mad cow disease are ingested from the environment, the prions found in the man’s brain had been inherited and passed down within
In the first half, he uses details such as, “Our bodies need darkness to produce the hormone melatonin, which keeps certain cancers from developing, and our bodies need darkness for sleep.” Proving the point that in order to avoid those diseases, our bodies need that darkness. In addition, he also uses the fact,” Sleep disorders have linked to diabetes, obesity, cardiovascular disease and depression…recent research suggest
For example, chronic insomnia may increase an individual’s risk of developing a mood disorder, such as depression and anxiety. The most common effect of sleepless night is insomnia. In one major study of 10,000 adults, people with insomnia were five times more likely to develop depression. Lack of sleep may be an even greater risk factor for anxiety. In the same study, people with insomnia were 20 times more likely to develop panic disorder ( a type of anxiety disorder) ( Harvard Medical School, “Sleep and Disease Risk”). Not to mention obesity, Diabetes, heart disease and hypertension, immune function et cetera. All these health problems are linked back to sleepless
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.
A study was completed by a Postgraduate medical student. The study revealed certain factors that could interrupt people daily day-to-day activities (October 2002). There are quite a few people who are not sleeping on a regular basis. An interesting quote was made by a writer by the name of Arianna Huffington. “Sleep Deprivation is the new smoking” (Huffington, 2016). Why is sleep deprivation called a new smoking? “Interesting concept” Huffington does a lot of research when it deals with sleep deprived individuals. This quote is a very powerful quote. Huffington is known as a great author who has written at least 15 books. She is a very knowledgeable author when it involves relaying facts about this serious sleeping disorder. She
As sleep researchers study sleep and try to unlock the mystery and the main purpose of sleep, they realized that some of the patients with heart diseases sleep deprived. Heart disease can be linked to high blood pressure which is also another health problem linked to lack of sleep. A persons chance of getting heart disease isn't just based on the amount of sleep they get. Exercise, smoking, an unhealthy diet, etc can also contribute to the illness. But sleep deprivation increases the chance of obtaining heart disease. Christina Boufis is a health and medical writer who covers an array of topics, but in her article "How Your Sleep Affects Your Heart" she explains why heart disease can come from lack of sleep. In her article, Boufis says, " One 2008 study from the University of Chicago found a link between shortened sleep and increased coronary artery calcification (calcium deposits), "a good predictor of subsequent coronary artery disease," says researcher Diane Lauderdale, PhD, professor of epidemiology at the university's Pritzker School of Medicine." Christina also agrees with Diane Lauderdale and explains how lack of sleep doesn't cause heart disease, but increases chances. Also in her article, she brings up fifteen different studies that involved about 475,000 people that found that people who suffered from lack of sleep had a forty-eight percent increased chance of attaining or dying from coronary heart disease. With this evidence, researchers and doctors can now help people lower the chance of getting heart diseases all through a simple cure, sleep. Not all heart disease can be eradicated by sleeping more, but this can lower a person's chance of getting it. Doctors have also found that better and longer sleep helps patients already suffering from heart disease. Heart disease can affect anyone, so a good night's sleep is always a beneficial way to the risks of developing heart
Sleep is an essential part of any person’s health, however few people seem to realize that not receiving enough sleep can double the risk of becoming obese.“The ‘epidemic’ of obesity is paralleled by a ‘silent epidemic’ of reduced sleep duration with short sleep duration linked to the increased risk of obesity both in adults and in children”(Professor Cappuio). Someone who has developed a sleeping disorder such as, sleep apnea, may not have the motivation to diet or exercise, due to daytime sleepiness. Scientists at the University of Chicago conucted a study in 1999, which restricted eleven healthy young adults to four hours of sleep for six nights. The scientist discovered that restricting individuals to this amount of sleep impaired metabolism functions and disrupted hormone levels. It was also found that the subject’s abilities to process glucose in the blood had declined, in some cases to the level of diabities. ” Not only does obesity contribute to sleep problems such as sleep apnea, but sleep problems can also contribute to obesity.”(National Sleep Foundation)
