Why won't they get out of bed in the morning? They may like to sleep in, but teenagers are often actually chronically sleep deprived. Host Steve Cannane discovers that teen brains are wired to stay up late, sleep in and sleep more. But over a million Australian adolescents are struggling with this basic human process. With the assistance of five teen night owls we discover why, and what can be done to help them. We uncover the biological basis for adolescent sleep problems, undertake a series of tests to determine the damage sleep deprivation has on teenagers, and join one teen who tries to restart her body clock using bright light therapy.
