Every morning, across the country, millions of teenagers drag themselves out of bed while it's still dark outside. Their bodies tell them to sleep; their alarm clocks tell them otherwise. And the science is clear: the alarm clocks are wrong.

Research from the American Academy of Pediatrics shows that adolescent circadian rhythms shift during puberty, making it biologically difficult for teens to fall asleep before 11 PM. When school starts at 7:30 AM, most students are getting far less than the recommended 8-10 hours of sleep.

Schools that have shifted to later start times report remarkable results: higher test scores, fewer car accidents among teen drivers, reduced rates of depression and anxiety, and improved athletic performance.

The counterarguments — bus schedules, after-school activities, parents' work hours — are real but solvable. Several districts have already figured it out. If they can do it, so can we.

Our bodies aren't lazy. They're telling us something important. It's time our schedule listened.
