Abstract
Most teenagers experience chronic sleep deprivation. Delaying secondary school start times is a proposed solution to increase adolescent sleep by allowing students to wake later without changing their biologically determined bedtime. This study, conducted in the Seattle School District after a near-hour delay in secondary school start times, used objective data from wrist activity devices and sleep diaries to demonstrate a 34-minute increase in median daily sleep duration. This was associated with a 4.5% increase in median student grades and improved attendance.
