How many hours does it sleep
A 14 year old girl should get ad least an 8 hour sleep. If you sleep to little you can get very unhealthy and be kinda grouchy. If you get to much sleep then theres a possibility you can dose off and go into a coma. Keep that 8 hours. Or you can go for 8 hours and 30 minutes. :)
8 hours 12 year old should go to be 10 to 11
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
