How Much Sleep Do I Need? Most teens need about 8½ to more than 9 hours of sleep each night. The right amount of sleep is essential for anyone who wants to do well on a test or play sports without tripping over their feet. Unfortunately, though, many teens don't get enough sleep. Why Aren't Teens Getting Enough Sleep? Until recently, teens were often given a bad rap for staying up late, oversleeping for school, and falling asleep in class.
