A new study suggests starting school later could help students perform better in class.

The authors say the sleep-cycle changes to a later time when kids become teenagers.

They studied how high school students slept when school started 25 minutes later than normal and found nearly half of students got 8 hours or more of sleep, compared to the 18-percent that got enough before.

They say with enough sleep, teens are happier, more alert, and better prepared to learn.
