What is the amount of hours that someone has gone without sleep?

Question

i want to know how many hours a person has gone without sleep cause i am going to challenge my friend to a contest to see who can stay up the longest.

Answer 1

I'm am not exactly sure the longest time anyone has gone without sleep. However for everyone that is saying "Oh I stayed up for 11 days once" Is ridiculous. After around 10 days you body begins to cease function and you die. Secondly the amount of mental capability is so low that thinking properly almost out of the question. Motor skills would also be incapable of functioning properly. It's almost like when your aren't breathing. You may be fine for a while although stressed then from the lack of it, but after a bit your brain starts to strain and you could end up causing brain damage. After to much oxygen strain your body begins to shut down and you die. With a lack of sleep you can also cause permanent damage to your body and brain.

Answer 7

The world record would be 11 days. i think.

but i would not recommend doing it because of health concerns.

Answer 8

Medically there is an extremely rare condition wherein an individually is physically incapable of sleeping, so technically the answer is forever.

For your purposes, however, I have read military sleep deprivation studies from the 1970s which discussed the effects of lack of sleep for 100+ hours (4 days straight) and 4 hours of sleep per night thereafter.  If you can make it 100 hours on no sleep you are doing pretty well - most of the volunetter who made it that far were functioning with a severely limited mental capacity, although physical capacity (your ability to perform motor function like walking, etc.) lasted far longer than mental functions.
