Practical applications of circadian science in adolescents

Two studies published in this volume in The Journal highlight the contribution of circadian rhythms to seemingly disparate aspects of health in adolescents: driving safety and glycemic control. Both studies appropriately take into account sleep duration as necessary, but not sufficient, to explore the relationship of sleep with these topics. Owens et al determined that for a cohort of teen drivers, not only was shorter sleep duration associated with drowsy driving, but also a more pronounced "night owl" tendency, or evening chronotype.
