Ask the Doctor: Teens and sleep
Q: How much sleep do teenagers need?
A: Our answer may surprise you. Even though the average teen tries to get by on very little sleep, in fact, teens need more sleep than younger children. The National Sleep Foundation suggests that teens need an average of more than nine hours of sleep each night.
Many teens stay up late. They often get only six or seven hours of sleep per night, since they have to get up early to be at school on time. To get enough sleep, a teen that needs to get up before 6 a.m. would have to go to bed by 9 p.m. Obviously, most adolescents do not go to bed this early.
Although it may not seem "cool' to get enough sleep, it can help teens do better in school.
