Adolescents are a sleep-deprived group, with an estimated 87% of high schoolers getting insufficient sleep on school nights and 40% reporting six or fewer hours. This “teen sleep crisis” is believed to have many causes, including a delay in the circadian rhythm at puberty coupled with school start times requiring early awakening. A compelling body of research shows that these latter two factors account for a significant portion of chronic sleep deprivation in adolescents; in fact, of all the contributing factors proposed, only early school start times have been proven to play a major, and remediable, role. These findings have led to a growing number of calls from health, education, and civic leaders for later school start times, including recommendations from the American Academy of Pediatrics and the Centers for Disease Control and Prevention that middle and high schools start class no earlier than 8:30 a.m. Nonetheless, an estimated 85% of U.S. middle and high schools still start class at times out-of-sync with typical adolescent circadian patterns; many start in the 7 a.m. hour or even earlier, with students in some districts required to be at bus stops before 5:30 a.m. After briefly reviewing the history of school bell time changes and recent research about the impact of early bell times on health, safety, school performance, equity, and economics, this talk considers perceived and real obstacles to change, as well as recent lessons from communities that have successfully returned to more developmentally appropriate school hours.
