What does lack of sleep do to a person?

Answer 1

runs u down u need sleep r u'll end up walking round like a zombie go 2 sleep darling

Answer 2

It makes a person very tired, it makes a person very irritable/ tense/ edgy/moody/ and in many cases for lack of a better word 'weird/crazy/hysterial' and socially distant, it progressively and severely interferes with a person's ability to concentrate, understand and make rational decision and it causes muscles to begin twitching.

Eventually sleep deprevation can result in death/ if the person is not allowed to sleep, chances are you will collapse much sooner than this happens but in Hitler's time he would not allow prisoner's to sleep and everytime they slept they would be woken up, until they died. Because the body is unable to repair itself as well. If you're prone to head aches you'll get plenty of those too/ and your eyes will have a lot of trouble focusing. You may also fall asleep while leaning over a balcony or over machinery or a sharp object and either fall to your death or hurt yourself badly. Funny, how something as simple as sleep is so necessary.

If you stay up nights and nights studying, its also alot of wasted time because lack of sleep causes you to become slow and you hardly retain any of the information. So overall it has the biggest impact on the brain, and then begins to show physical signs. What goes on inside is much worse than the outside, but its even evident from looking at someone face, you can get permenant dark circles under your eyes like mine and the body's inability to repair itslef results in a haggard experience. And if You're young and still growing, since you only grow in your sleep, extended periods of time where someone does not get enough sleep interferes with their routine (so they may not be able to sleep when they need to or want to) - plus it affects the levels of various hormones in the body which are released while you are asleep so kids who don't get enough sleep often stunt their growth.

Answer 3

YOU GET TIRED AFTER A WHILE some times, they also make your eyes go funny because when you sleep it helps your eyes, you also may not do good at work/school because you aren't allowing your brain to rest

Answer 4

head ache ,lack of concentration, sluggishness, burning eyes, irritation in the eyes , black circles under eyes, to name a few. all these things will disappear once u sleep well

Answer 5

behaviorally speaking, it makes a person tired, slow, cranky, can't concentrate properly and makes poor decisions. physiologically, it impair your body's capacity to regenerate new cells, hence, the dry ugly skin, and also, you're keeping your body from being able to make the repairs that are necessary for normal body functioning.

Answer 6

When you are in your early twenties, work full time, go to school (college) full time, party with your friends that aren't going to college, and you live on your own, I'll tell you. You don't eat right or take care of yourself. It leads to strep throat, that becomes Mononucleosis, almost kills your kidneys.

Been there, did that.

Lack of sleep affects everything...your concentration level, your ability to retain information, your stress management,etc....

We don't all need 8 hours of sleep every day, but our bodies must have a period of continuous rest. If not, it will rebel.

Answer 8

Irritable, lack of concentration, forgetfulness, red eyes....I could go on

1. As a cause of death. In humans, extended sleep deprivation causes microsleep sessions to develop. A person who has fatal familial insomnia may die after several months with no sleep at all; people without this condition may experience dementia or develop permanent personality changes within the first few weeks.

2. As a cause of diabetes. Sleep deprivation severely affects the human body's ability to metabolize glucose, which can lead to early-stage diabetes.

3. Effects on the brain. Depending on the task at hand, in some cases the brain attempts to compensate for the adverse effects caused by lack of sleep. The temporal lobe, which is a brain region involved in language processing, was activated during verbal learning in rested subjects but not in sleep deprived subjects. The parietal lobes, not activated in rested subjects during the verbal exercise, was more active when the subjects were deprived of sleep. Although memory performance was less efficient with sleep deprivation, greater activity in the parietal region was associated with better memory

4. Effects on growth. Fetal and childhood growth retardation.

5. Impairment of ability. According to the National Highway Traffic Safety Administration, sleep deprivation can have some of the same hazardous effects as being drunk. Getting less than 6 hours a night can affect coordination, judgment and reaction time. People who drove after being awake for 17–19 hours performed worse than those with a blood alcohol level of .05 percent, which is the legal limit for drunk driving in most western European countries (most U.S. states set their blood alcohol limits at .08 percent). The study stated that 16 to 60 percent of road accidents involve sleep deprivation.

6. As a cause of obesity. Research suggests that one cause of obesity is a result of sleep deprivation (by disruption of hormones that regulate appetite.) The study found that people between the ages of 32 and 49 who sleep less than 7 hours a night are significantly more likely to be obese. Other scientists hold that the physical discomfort of obesity and related problems, such as sleep apnea, reduce an individual's chances of getting a good night's sleep.

7. As a treatment for depression. Recent studies show sleep deprivation has some potential in the treatment of depression. About 60% of patients, when sleep-deprived, show immediate recovery, with most relapsing the following night. The incidence of relapse can be decreased by combining sleep deprivation with medication. Incidentally, many tricyclic antidepressants happen to suppress REM sleep, providing additional evidence for a link between mood and sleep

8. Prevention of effects in soldiers. Since sleep deprivation is a fact of modern combat, the U.S. Army, through DARPA, has a "Preventing Sleep Deprivation Program", which has the goal to prevent the harmful effects of sleep deprivation and provide methods for recovery of function with particular emphasis on cognitive and psychomotor impairments. Their efforts include new pharmaceuticals that enhance neural transmission, e.g., a new drug called modafinil, which has prevented the negative effects of sleep deprivation in soldiers. Modafinil may increase wakefulness through activation of noradrenergic and dopaminergic systems, possibly through interaction with the hypocretin/orexin system.

In the long term, the clinical consequences of untreated sleep disorders are associated with numerous, serious medical illnesses, including high blood pressure, heart attack, heart failure, stroke, psychiatric problems, Attention Deficit Disorder (ADD), disruption of bed partner's sleep quality, and poor quality of life.
