How many hours does it sleep
if you mean how many hours you should sleep in a year it would be 3,650 hours of sleep for a regular year not a leap year
About 8 to 12, depending on your age. :)You must sleep, otherwise you will feel ill and especially if your brain hasn't rested enough.

I sleep about 7 to 9 hours a day
Its compulsary for a teen ager to sleep 8 hours..
6 Hours of sleep is enough
they sleep about 3-6 hours a day

You should sleep six hours in the morning.
at least 9 or 10 hours to get enough sleep
The average is 8 hours, some people require 10 hours and there is approximately 35% that only need six hours (I'm one of those people.) It depends if you have REM sleep (deep sleep) and if you do then even six hours is enough for many people. If you are a lighter sleeper then 8 - 10 hours is a must. Children from 1-19 need at least 10 hours of sleep each day.
