High School & Sleep

Extracts from this document...


High school does not start at a reasonable time. High school is asking adolescents to wake up at an early time when their circadian rhythm tells them to wake up later.

In Lexington, Kentucky, when school officials decided to push back the starting time of middle school and high school by an hour, two things happened: the students reported getting more sleep, and traffic accidents involving teenagers went down. That means because the students got more sleep, they got into less driving accidents because they were not feeling tired or drowsy. Serious issues occur when adolescents are not getting enough sleep.
