How long can humans survive without sleep?
Answers:
No-one healthy will die from straight-forward lack of sleep. When you become very sleep deprived, your mind takes little micro-naps of a few seconds of REM even if your eyes are open, often leading to hallucinations (happened to me once!).
However, the reason for you not sleeping may be dangerous. There is a very rare degenerative brain disease called 'malignant insomnia' where you die after not sleeping for about a month. A more common reason for not sleeping is a psychiatric illness, such as mania where people will exhaust themselves in other ways because they do not feel fatigue.
This is not an excuse not to sleep! Good shut-eye helps your memory and problem-solving, making you seem more intelligent and have better relationships.
22 days
i believe it was 4 days
Don't quote me, but I read somewhere that you would never die from lack of sleep - you would fall asleep before that could happen.
this varies from person to person. Some cant stay awake 24 hrs. I have stayed awake 4 days.(military). It depends on how hard you push your body till it becomes totaly exhausted. Lack of sleep will not kill you per se. But it could lead to other problems that could affect your health.
lack of sleep will not kill you it may cause some mental problems but there have been insomniacs known to be awake for months on end
3 days
Till you pass out.
"There 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 .[10]. Total sleep deprivation in rats leads to death in around 28 days. Death occurs later[citation needed] 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."
The genus book of records has 7 days and i forget the hours and min. Insomniacs are different from not sleeping. They still close there eye's and get a lesser form of sleep. You can die from lack of sleep. It has been documented.
I'm not really sure, but I read somewhere that there was a study conducted wherein they compared two groups of people; first group, are the people whom they deprived of food; second group were the people whom they deprived of sleep. In the end, they found out that those who were deprived of food lived LONGER than those who were deprived of sleep. So, that tells us something scary..
I once knew a guy who had been up for nine days..no kidding..he was going crazy but that could have been b/c of the meth that he was doing.
