Thirty years of research has shown that teenagers’ biology prevents them from getting to sleep much before 11pm, and with most high schools starting classes around 8 am, they are chronically sleep deprived. Experts discuss how students and even the economy would benefit and why many school districts still oppose the change.
Start School Later, aka Healthy Hours, is a non-profit organization in the United States. Founded in 2011 after Maryland-based science writer Terra Ziporyn Snider started an online petition via We the People that brought together grassroots advocates, sleep researchers, pediatricians, social workers, and educators, the coalition aims to help communities delay school starting times; ensure safe, healthy school hours; and provide sleep education programs for students and school communities.
