This document discusses how teen sleep patterns are affected by school start times, with later start times allowing teens to get more sleep and experience better academic performance and health outcomes. It explores the science behind teenage brain development and circadian rhythms, noting that melatonin production is affected and optimal sleep patterns for teens are misaligned with typical early school schedules. Delaying school start times could help address insufficient sleep and its negative impacts on teens' physical, mental, social, and academic development.
