It's a misconception that teens require less sleep. They do get less sleep because of their hectic schedules (see "Today's Tired Teens"). Teenagers need 8 hours at the minimum, and ideally ten hours for complete health. This way, they don't fall asleep in class. Parents should help their teens establish a regular bedtime and a before-bed routine.

College students aren't known for getting much sleep, but they still need 8 hours to function and to succeed. When you're in college, it's up to you to manage your time and say "no" to extra activities that may crowd your schedule. All-nighters before an exam may actually hinder your memory (see "To Sleep, Perchance To Learn.") Sleep during the week, and then you'll be free to go out on the weekends. For students juggling school and a job, sleep is doubly important, so make the time.
