Sleep And The Immune System Essay

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

ii. On serendip.brynmawr.edu, they talk about how sleep deprivation weakens the immune system, preventing the body from being able to ward off infections and viruses.

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.

FACT: Scientific research is showing a correlation between poor sleep and health. If you’re not getting enough sleep and/or are waking frequently during the night, you may experience an elevation in blood pressure, which normally decreases during sleep. This can cause cardiovascular problems. Studies also have shown that lack of sleep can have an impact on blood sugar levels, with the body’s reaction being similar to insulin resistance.

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

Waking the sleeper momentarily so that he can start to breath properly again. The pattern repeats itself throughout the night and the heart has to work harder creating a rise in blood pressure. Left unchecked, the stress sleep apnea will place on the heart and the increased blood pressure can lead to serious heart disease, stroke or even heart failure. Often sleep apnea sufferers are not aware that they wake up and go back to sleep.

It is basic knowledge that humans need sleep, but that’s where it ends just general knowledge. The article “Sleep On It” discusses how not getting enough sleeps affects you and also remedies to help. I personally am one of those people who sleeps less and says, “I’ll just be tired tomorrow, it’s okay.” After reading this article I now realize how I am putting my body in danger of future risk and it’s not okay. The article discusses that people who get no more than six hours of sleep are at a higher risk of diabetes, heart disease, and gaining more weight. Although the studies mentioned do not show causations, I feel like the correlations are strong enough to understand the negative effects. I found it very interesting no matter which study

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

Sleep presents the body with an opportunity of repairing and recuperating itself. Poor sleeping habits or lack of sleep entirely promotes an unhealthy immune system, making an individual susceptible to sickness. Recent studies have shown that people who sleep for less than six hours every night are 4 times more likely to be infected with flu that the ones that get seven or more hours of sleep.

The circadian clock holds large importance in a number of bodily functions including the cardiovascular system. In particular there are a number of connections between the circadian clock and myocardial infarctions (heart attacks). Myocardial infarctions (MIs) as a term is more commonly used in scientific journals than heart attacks, therefore, the term myocardial infarction (MI) will be used throughout the duration of this paper. Overall a discussion of the link between MIs and the circadian clock, the effect of disrupted sleep on MIs, and certain cases where there is an attenuation of the link between the circadian clock and MIs will be considered

Lack of enough sleep contributes to cardiovascular diseases; persons who take less time sleeping have a better chance of getting cardiovascular illness.

3. Weakened immune system and vaccinations: Sleep deprivation makes it more likely you’ll get sick or develop an infection. In one study, people who slept less

Everyone has had a time in their life when they felt a little sleep deprived; there was a time in their life when they felt more tired than usual. It was either just a busy work week, or one night accidentally stayed up a few hours longer, but college students bring a new meaning to sleep deprivation. We are reported to be the highest number of sleep deprived people. Sleep deprivation comes in two stages: chronic and acute, whichever category, both come with extreme side-effects. The effects of chronic sleep deprivation form long-lasting symptoms and can lower your body’s natural defense system. One of the more obvious signs of sleep deprivation is yawning and increased irritability. As well as the obvious signs, chronic sleep deprivation has been linked to parts of the brain that decreases coordination and decision-making abilities. How many times have we reached a stage of exhaustion and called it “slap happy?” For the other stage of sleep deprivation, acute deprivation is more noticeable as it shows through appearance. Skin can start showing signs of hypoxia, which is when not enough oxygen is reaching the surface of the skin. Sleep deprived people’s skin can appear to be a pale, dull grey color. It is almost expected of college students to be sleep deprived and barely getting five hours a sleep a night. It is true, college students are almost walking zombies during the week. With the balance between classes, social life, working out, extra activities, and those that are

The dangers of sleep deprivation may affect a teens’ physical well-being in several ways. Some students may not realize that adequate rest and a functioning immune system are closely related. The blood levels of

Why is sleep so important to us? There have been studies done that suggest that sleep deprivation can be detrimental to or decrease the function of our immune systems. Just think, how often was it that after many days of continual sleep deprivation did you start to think that you had a cold? Sleep deprivation can also result in a decrease in core body temperature, decrease in the release of growth hormone, and possible cause an increase in heart rate variability. Sleep also seems to be important in order for our nervous system to work properly. Without sufficient amount of sleep, our behavior and our ability to do things are impaired. We feel drowsy and are unable to concentrate after not getting enough sleep. With enough sleep deprivation, it has been found that some begin to hallucinate and develop mood swings. Higher-ordered cognitive task become more difficult to do where it has been shown that tests that require speed and accuracy have lower results compared to those that are not sleep deprived. Judgment is also impaired; it has been tested that riskier behavior is more likely to occur when sleep deprived. (2).This is part of the reason why you should not drive when you are sleep deprived. Aside from the risk of falling asleep at the wheel, since judgment is
