My doctor has told me that tweens need 9 hours of sleep a night! A Sleep Doctor should tell you to sleep 10 hours of sleep not 9 hours. Now Adult can sleep up to 6 hours, there bodys don't need that much sleep:)
Lizards needs 11hrs of sleep
an adult need sleep of maximum 8 hours.
between 5-7 hours of sleep. Children need at least 7-8 hours of sleep
alot
Around 8-9 hours sleep a night is best. As teenagers need enough sleep to get all there energy back
Because they haven't had as much sleep as you have and they need to catch up on their sleep and that is why the older they get the less they sleep beause they are getting caught up.
About 10-12 hours
8 to 10 hours is the best for then to do... 11 might be just a bit too much
8 or more
A labrador retriever needs as much sleep as other dogs, 12-14 hours.
