Are students getting the sleep they need? Teens don’t get enough sleep. Furthermore, it’s not because of Snapchat, social lives or hormones. It’s because of public policy, says Wendy Troxel. Troxel draws from her experience as a sleep researcher, clinician and mother of a teenager. She discusses how early school start times deprive adolescents of sleep during the time of their lives when they need it most. This talk was presented to a local audience at TEDxManhattanBeach.
