I personally don't know. But in experiments and stuff people have stayed awake for 12 to 18 days.
14 and a half days, set by Randy Gardiner in 1965.
About three days without any sleep what so ever.
* It's not a matter of how long someone can live without sleep but a matter of how long can someone stay awake without passing out. Probably not more than two days. * You can find normal people staying awake for three days. You can find exceptional people to stay awake for 30 days. Some extra exceptional people lie awake for more than 20 to 30 years. * The current record is a bit over eighteen days, but this SHOULD NOT BE ATTEMPTED.
The riddle "How can a man stay awake for eight days?" has a clever twist: the answer is that he sleeps at night. The phrasing implies staying awake continuously, but by sleeping during the night, he can remain awake for the entire duration of the day over eight days. It's a playful reminder that the interpretation of words can change the meaning of a scenario.
Days Awake was created in 2004.
The longest that a human has stayed awake is just short of 11 days, so theoretically staying awake for eight days is doable. However it is not healthy and you should not attempt it.
