Sleep is VERY important.  100 years ago, people got 8-9 hours of sleep, today it's dropped to 6-7 hours.\n\nThe body heals itself when you sleep, also helps the brain to rest.  Did you know that if you go for 2 days without sleep that you can have all the effects and hallucinations of being on drugs?  You react slower in driving, simple tasks become overwhelming, etc.\n\nMake sure you get enough sleep, the body needs it!\n\n(When you become a parent, you never get enough sleep) so get it while you can

http://en.wikipedia.org/wiki/Randy_Gardner_(sleep_deprived)......       That link is the world record for sleep deprivation. No you will NOT....I repeat NOT DIE from lack of sleep. You will die without food and water of course....Your body will eventually just shut down and stop. You will pass out...The record(seelink) is 11 days. I do know not sleeping enough wont kill you. Ive had too many friends that were chemically dependent....I'll just leave it at that

it depends on the person, i mean there are people who have really low blood sugar and can absolutely not miss more then 2 meals, but then look at anorexic people that go like 8 hours, and then only eat like a carrot...\n\nif you mean eating entirely-humans can only last 3 weeks without any food.

The record is something like 12 days or so by a kid. Everyone will eventually succumb to the need to sleep but when in the question. They cannot figure out why our body needs sleep and one one has ever died from a lack of it. Some theorize that we sleep because back in the day humans needed to stay in at night to avoid getting killed by nocturnal animals.

No, it's not "ok".  You're not giving your body the rest it needs to recuperate and heal and eventually you will have sleep deprivation.  The average person needs at least 8 hours a night...some a little more.  Sleep deprivation can cause a lot of health problems, so get some more shut eye for your own sake.  Now go take a nap!

Although it depends to some extent on age, scientists say just about eight hours per night is the minimum to remain healthy and alert. The effects of sleep depravation include short term memory loss and impaired reflexes and motor skills, so heads up for that if you go  on living at five per night. \n\nI'm a college student, so I feel you on that one. :p

yes you can but it sucks.........your brain re charges after 4 hours of sleep, the other 4 are for your body, but your body can function on a half charge, so if you sleep roughly 4 hours a night that's all you really need to keep from getting nerve disorders and shit like that witch will kill you, Ive heard that a person will die if they go more than 4 days straight with out sleeping. Also, I dint know how long they would go but I have heard the Nazi's would force Jewish prisoners to work until they died from exhaustion.  \n\nI myself have conditioned myself to the point that I could stay awake while driving after 4 and a half hours sleep each night for a week, but the tax it in poses on the body is not cool. After about a year and a half I became allergic to the sun, doc. said that it was because one of my origins was increasing the out put of some long named chemical that I cant pronounce or come close to spelling, all thanks to a lack of sleep. my doc. recommended at least 6 hours of sleep each night, I sleep 6-7 hours and stay healthy

if you dont sleep enough, youll gain weight, you need a good amount of sleep in a good rhythm (about 8 hours are perfect for adults, children and teenagers need more)

This is an interesting one which I think depends on what we THINK we need. Most folk in UK seem to generally consider we need 8 hours or thereabouts. I joined a group once which stated that if you needed more than 4 hours there was something the matter with you. This struck me as quite ridiculous on first hearing it but I gradually realised that our perception and conditioning are an enormous influence. I now KNOW I can manage quite well with 5 or 4 hours but have the capacity to sleep for 12 hours too. I am truly blessed to be able to drop off almost the minute my head touches the pillow.

8 hours is recommended, but it really depends on each person. Some people can function properly with 5-6 hours and some can not. You should try sleeping less than 8 hours and see how much sleep you need.

WebMD's article on sleep, which was reviewed by the Sleep Medicine Center at the Cleveland Clinic, and cites the National Institutes of Health and the National Sleep Foundation as their sources, state that:\n\n"The amount of sleep a person needs depends on the individual. The need for sleep depends on various factors, one of which is age. Infants usually require about 16-18 hours of sleep per day, while teenagers need about 9 hours per day on average. Most adults need about 7-8 hours of sleep per day.\n\nThe amount of sleep a person needs also increases if he or she has been deprived of sleep. People do not seem to adapt to getting less sleep than they need. "\n\n\nSweet dreams :)

Depends on your age! The average is about eight hours for anyone under the age of 18. Above that is 6-7 hours. But if you feel like you need to sleep longer or shorter lengths, it's all up to you! Some days I sleep for five hours, others almost ten to twelve!

A healthy adult, from ages 16 to 38 or so can get by on about 4 hours of sleep a night.  However, it is reccomend you get from 6 to 7 hours of sleep.  8 hours of sleep was mandated for many years, but found to be non optimal.\n\nChildren under the age of 16 should get at least 8 hours of sleep or more.  Infants and toddlers, preschoolers and such should get more than 10-12 hours of sleep per day.\n\nOlder adults from ages 38is to 60 should get about 8 to 10 hours of sleep per day to help their bodies recoup the daily losses.  \n\nOlder people, from ages 60+ should usualy get from 10-12 hours of sleep a day to help recoup the losses.\n\nMind  you these are optimal hours, the range can be decreased and increased based on the activeness of the person.

The most anyone can sleep is most definitely NOT 8hrs. I have had friends who slept for 24hrs straight. It all depends on how much of a "sleep deficit" you have. \nYour body needs a certain amount of sleep, and that differs for everyone. However, it is recommended that we get around 8hrs per night if we are to function at our best. \nSleep is important for many reasons - helps with "solidifying" your experiences and memories that you have from the previous day, recharges you with energy - I think it's pretty obvious. \nAbout the day vs night sleep? It is best to sleep during the dark hours because the production of MELATONIN - a hormone that regulates sleep-wake cycles - varies with exposure to light. \nI also happen to be "nocturnal", but this is causing me a lot of problems. I cannot imagine how it would feel like to wake up feeling refreshed before 11am!

I need around 6-8 hours sleep.  Anything less than 5 hrs and you can bet I'd be dangerously cranky and would be snapping at everyone the rest of the day, plus, I won't be up to any "thinking" tasks such as heavy analyzing and all that. I'd be on auto-pilot mode then until I get enough sleep. I usually wake up for bathroom breaks but I try not to turn on the lights (autopilot mode again) so that I can go right back to sleep without being woken up too much.
