Help! is 5 1/2 hours of sleep enough on a regular basis for a growing teenager?

No.: To elaborate further, no. If anything, teenagers need more sleep (up to nine hours per night) than fully-grown adults.

No: need 8-9 hours sleep a night. Need to change your life style and get enough sleep.

Never: A teen that is still growing will need ~9 hrs of restful sleep/d with more if they are involved in sports or studying hard for exams.Lack of adequate sleep leads to symptoms such as difficulty focusing, forgetting & diminished motor control.Some will develop sleep talking or sleep walking.After growth stops, most can get by on 8, but brain connections continue to form until 22-25 and rest helps.
