What happens if you stay up for 2 days?

Answer 1

The brain relies on sleep to recharge and so does our bodies. If you don't sleep you will start to experience psychological problems and hallucinations. Eventually the body will shut itself down as a protective measure.

Answer 2

People who remain awake too long eventually become delirious and may get physically ill. How long is "too long" depends partly on what you're used to; many people can handle two days on occasion without a great deal of difficulty... though by around midway through the second day they're not likely to be performing at their best.

Answer 3
