What time is best for teenage to sleep, and when to wake up?

Bed at 10; up at 7: Now, having said that, i realize that in this day and age it is very difficult to follow a sleeping pattern like that. However, that would be the pattern that would be ideal for your health. Best wishes.

Sleep: Changes in adolescence makes teens feel more comfortable staying up late and sleeping in, but school schedules mean that many teens don;t get enough sleep. Without 8.5 to 9.5 hours per night, teens often get irritable and have trouble paying attention. Look at the time you have to get up to go to school, then plan on going to bed ~ 9 hours before.
