What's the longest someone has gone without sleep? How long could a human survive without sleep?

Question

What would they experience through sleep deprivation?

Answer 1

didnt they try this a few years bak on a reality show?

Answer 2

Hmmmmmmmmmmm ... Бих казал, вероятно една седмица? А седмици и половина?

Answer 3

The longest time ever was 18 days, 21 hours and 40 minutes.

The longest I've ever done is 6 days - you get hallucinations usually after 3 days which is pretty cool though your bodies defences suck!

Answer 4

11 days sounds about right . staying up for 48 hrs is not that difficult as-long as you are doing something and not sat down relaxing.

My job often requires me to stay up at least 24hrs.

Answer 5

i think it was 6days

Answer 6

some of my military friends who trained for seals were forced to stay up for like 2 weeks...

Answer 7

11 days (something like 264 hours). This was done in the sixties by a high school student for a science fair.

This could be very dangerous. Staying up that long could cause a whole host of problems, including hallucinations and delusional thoughts. Even worse, your body starts to shut down without sleep, because it needs to rest and restore your energy.

Answer 8

My own record is around 50 hours.

I experienced headaches, stress, anxiety and a pronounced lack of proper coordination.

I became more forgetful, and a little belligerent.

As an Insomniac, due to a reaction to medication, I often have to just relax and stop worrying about lack of sleep.  

My record for too little sleep is more like a couple of months with similar results to the above.

Answer 9

Nobody really knows why, but people who go for extended periods without sleep often have long term health problems. It's not a case of stay awake for x hours and you'll die, more a case of long term effects.

I seem to remember the person who set the longest time in the Guinness book of records worked for a radio station. He had mental problems later which he put down to the record breaking attempt I think he totally lost his ability to concentrate.

Maggie Thatcher was well known for only sleeping around 5 hours a night during her term in office and she has since suffered several minor strokes and other ailments. There are several other similar cases.
