A new report indicates that science agrees with teenagers everywhere – school should start later:
Seeing the mounting evidence, the American Academy of Pediatrics [last week] released a new policy statement recommending that middle and high schools delay the start of class to 8:30 a.m. or later. Doing so will align school schedules to the biological sleep rhythms of adolescents, whose sleep-wake cycles begin to shift up to two hours later at the start of puberty, the policy statement says. The conclusions are backed by a technical report [pdf] the academy also released yesterday, “Insufficient Sleep in Adolescents and Young Adults: An Update on Causes and Consequences,” which is published in the September 2014 issue of Pediatrics.
The “research is clear that adolescents who get enough sleep have a reduced risk of being overweight or suffering depression, are less likely to be involved in automobile accidents, and have better grades, higher standardized test scores and an overall better quality of life,” said pediatrician Judith Owens, lead author of the policy statement, titled “School Start Times for Adolescents.”
The debate over whether to start school later has run for years, but a host of new studies have basically put it to rest. For one thing, biological research shows clearly that circadian rhythms shift during the teen years. Boys and girls naturally stay up later and sleep in later. The trend begins around age 13 or 14 and peaks between 17 and 19. The teens also need more sleep in general, so forcing them to be up early for school cuts into their sleep time as well as their sleep rhythm, making them less ready to learn during those first-period classes.
