i think that astronauts usually get about six hours of sleep every night when they are in space.
How many hours does it sleep
Astronauts typically sleep around 8 hours per day while in space. However, the actual amount can vary depending on their schedule and workload.
Mercury carried one Astronaut, Gemini carried two, and Apollo three
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
you must get atleast 9 hours of sleep
I sleep about 7 to 9 hours a day
about 10 hours of sleep
Its compulsary for a teen ager to sleep 8 hours..
6 Hours of sleep is enough
they sleep about 3-6 hours a day
at least 9 or 10 hours to get enough sleep
