The average person is awake for about 14 to 16 hours per day. Most could extend that to about 20 hours if they were to stay up later; up to 40 hours is easy once a person gets beyond the 24 hour mark; longer than 60 hours (staying awake straight through two nights and three days) is rare, but doable; the record is 264 hours or 11 days straight.

But there are only 24 hours in a day, of which adults between the age of 23 and 60 are awake for 16-17 on average.So 4 hours seems a long time to call âbefore bedâ.n this poll it is counted as exercising in the 4 hours before going to bed.
