Question

How long can a human being stay awake without sleep at all?

Answer 1

I think it depends on the person.  We were pushed at times to see how we did, and different people crashed before others.  I usually made 72 before I started to zone out and I don't think I ever passed 80 before crashing for at least a few.  Of course, that was at work, when no help showed up. :)  I know it was easier to stay up when stuff was going on, hyped up and ready for something, but some are just natural party animals. :)

Answer 2

i have stayed awake for about 56 hours..... NOT because I wanted to, but I get insnomia a few times a year, and can't sleep.

My step son was up for 6 days without sleep.

Answer 3

Less than you would think. People who claim to not have slept for long periods of time are mistaken. They 'nap' without even knowing it. Just like water, you can only go so long without sleep. After a while you would start to hallucinate, see and hear things that aren't there.I would say no one can last a week, max.

Answer 4

We had this fund raiser thing for charity at school called the Awake-A-Thon where we had to stay awake from 8PM-8AM on a Friday night. I seriously couldn't sleep for the next three or four days. As sleepy as I was, I just couldn't fall asleep. At 17 yrs old, it couldn't have be that good for me =]
