(HealthDay News) -- Teenagers need 8 1/2 to 9 1/4 hours of sleep each night to feel good and perform well at school.
But the National Sleep Foundation cites a recent survey showing only 15 percent of teens said they got this much sleep on school nights.
The foundation says possible consequences of sleep deprivation include:
- Becoming more forgetful, and having trouble learning, problem-solving and concentrating.
- Developing acne and other skin problems.
- Developing aggressive or inappropriate behaviors.
- Gaining weight and overeating.
- Increasing use of nicotine or caffeine to stay awake.
- Becoming more likely to get sick, or injured from drowsy driving.
