UCLA researchers have reported that teenagers need more sleep than adults, because they are at an important stage of development. According to the National Sleep Foundation, only about 15% of teenagers polled slept 8.5 hours or more per night.
This is a dangerous situation, since fatigue can affect motor control, response times, cognitive development and performance, and more. Teens who aren’t getting enough sleep may have a harder time concentrating in class or meeting their full potential academically. They may also feel achy and generally terrible. Lack of adequate sleep can also contribute to mental health problems, including depression, anxiety, and other conditions.
