If you need to get 12 hours of sleep then you should see a doctor. It is not normal to feel tired all the time. You may be anemic.
Sleep requirements are dependent mainly on age and activity level. A baby normally has around 12 to 14 hours sleep; a teenager (12- to 17-year-old) should have 9 to 10 hours; an adult can normally get away with 8 hours of sleep.Adults need 7-9 hours of sleep. If still tired they should sleep even more.normally eight hours
8 to 10 hours but if she sleeps to much you might still be tired for more information go to: beinggirl.com
If you wake up still tired you may have a sleeping disorder. It is a common disorder and you shouldn't feel worried about it. If you don't feel tired when you wake up you were just really tired. If you have any more questions ask me on my bio page.

Maybe, he could be emotionally/mentally tired, not just physically.

Since you are still growing, a 12 year old girl should get 9-10 hours of sleep a night.
It all depends on the person. Some people still may not sleep. Basically, the answer to your question, is it varies. You could sleep for 3 hours, 7 hours, or even 12-20 hours. It depends on the person. If you are like most teens, If you are a teen, Then you can sleep for about 14 hours and feel recovered for the most part. If you are like me, You can sleep for 9 hours and feel perfect :D
