What happens if you don’t sleep for a day?

Can staying up late kill you?
Exhaustion and sleep loss can have plenty of consequences, but it’s pretty rare to die from lack of sleep. That said, operating on little to no sleep can increase your risk of having an accident while driving or doing something potentially hazardous.

Will your body eventually force you to sleep?
The truth is, it’s almost physically impossible to stay awake for days at a time, because your brain will essentially force you to fall asleep.
Can staying up kill you?
All of these physiological changes are reversible, though—take a nap, and you’ll be on the road back to normal. It’s possible that given enough time, sleep deprivation can kill you. While no human being is known to have died from staying awake, animal research strongly suggests it could happen.
Should I sleep for 2 hours or stay awake?
Ideally, you should try to get more than 90 minutes of sleep. Sleeping between 90 and 110 minutes gives your body time to complete one full sleep cycle and can minimize grogginess when you wake.
