Teens do need more sleep than adults, but they rarely seem to get it. In addition, teens' natural body clocks tend to lead them to a later sleep phase than adults. Teens should be getting around nine hours of sleep each night, and some might need even a bit more.
On average, teens need about 8 1/2 to 9 1/2 hours of sleep each night. If you fall asleep at 10 p.m., you'd need to sleep until 7 a.m. to meet this requirement. That's not always possible, especially if you have to be up before dawn to catch the bus or make swim team practice. Many teens suffer with chronic insomnia.
