Various biological factors help determine how long people can last without sleeping. Some people can go for longer periods of time than others. \n\nNotorious cases of record-setters include disc jockey Peter Tripp who in 1959 stayed up for more than eight days as a promotional stunt. After a few days, he began to hallucinate, seeing kittens, mice, and cobwebs. He also became paranoid, insisting that an electrician had dropped a hot electrode into his shoe.\n\nSix years later, high school student Randy Gardner attempted to break the Guinness Book of World Records for the longest time awake -- 260 hours. And after 11 days without sleep he suffered no hallucinations or paranoia and no psychotic symptoms.\n\nSome people with severe insomnia claim to have gone for several weeks without sleep. Though ususally in cases like this, even though they appear awake, their brain actually goes into a light sleep-like state.

It's usually depression that causes insomnia, anxiety, and hyperactivity.  Although no one has ever DIED from lack of sleep, it's best not to let this slide. Our human body needs between 7-8 hours of sleep every night to function at it's best. Make an appointment fora physical with you family doctor and make sure you tell him/her about your problems.

It depends on thier physical and emotional fitness.  I have a freind that spent years in a Navy Seal team.  That guy could go many days of pure physical torment and shrug it off.  On the other hand, poor physical fitness and poor nutrition could be dangerous if someone went without proper sleep.  P.S.  The Seal I mentioned was a real mean guy without sleep.....but far from death.

It depends how many hours you need - people vary mostly between 6 and 9 hours.\n\nIf you are getting all you as an individual need you will not get depressed, fat or otherwise - well at least not from sleep deprivation!\n\nYou wont get older faster but if you are sleep deprived it might feel that way!!

Sleep deprivation is an overall lack of the necessary amount of sleep. A person can be deprived of sleep by their own body and mind, insomnia, or actively deprived by another individual. Sleep deprivation is sometimes used as an instrument of torture, but it has also been shown to be an effective treatment of depression. Sleep deprivation afflicts 47 million adults in the United States.\n\nLack of sleep may also result in irritability, blurred vision, slurred speech, memory lapses, overall confusion, hallucinations, decreased sex drive, nausea, psychosis, and eventually death.\n\n(FURTHER INFO...)\n\nThere are no documented cases of a healthy human dying from total sleep deprivation (excluding accidents), aside from those suffering from Fatal Familial Insomnia. In carefully monitored experiments, several normal research subjects stayed awake for 10 days. While they all experienced cognitive deficits in memory, concentration, etc, none of them experienced serious medical, neurological, physiological or psychiatric problems [1]. Total sleep deprivation in rats leads to death in around 28 days. Death occurs later if only REM sleep is eliminated. 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.

That will depend entirely on what your thesis research involves.  If you are limited by library hours, or laboratory hours and experimental growth delays, it makes a big difference.\n\nIf you've got enough caffeine and enough limited access to your facilities it is possible to remain awake for 5 to 6 days without sleep, but I don't recommend it.

A normal can sleep 6 to 7 hours a day.Also it is good for health.Where as it is not good for health to sleep after having a lunch or dinner.So adults can have sleep upto 7 hours a day and that's the maximum.So If you are aadult follow this guidelines and have better life for tommorow

I think if you go too long (~4 or 5 days) your immune system will begin to break down and though lack of sleep itself won't kill you, a nasty bug getting through your weakened defenses could.\n\nWill have to check on that, though.

Ive heard that the average human being can go without food as long as they still have water for a full month.  I've personally gone 2 weeks without food.  Just to see.  Then I got so hungry that I got sick.  And I had to eat.  But at least I know what my limit is now!

Adult requires a minimum sleep of 6 hours a day, sleeps will seriously effect your health in a very big way, if you do not get enough sleep, your anxienty, stress level will increase with ease, your mind will not think properly and also that your health will deteriorate extremely fast. so please try not to sleep at the minimum of 6 hours, get a healthy 8 to 9 hours. \n\nIn Korea this guy died of being awake for 50 straight hours playing online game. A few cases has happend already. so Take care Cheers

Depends on whether they are hooked up to an IV, etc.  Ther eis no set time frame but generally a person can survive without water for only a couple of days ... no simple answer to your question.

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.

About four or five days. After that, he starts to hallucinate if forced to stay awake and if not forced to stay awake he will just fall asleep.

The guidelines on how much sleep people need are just that - guidelines. They are not one-size fits all, and different people need different amounts of sleep. If you are in good health and don't feel tired, then consider yourself lucky to need so little sleep. I seem to need around 8-10 hrs, which is a total drag and dosen't fit into my schedule at all - I wish I had your "problem" :).

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.
