Brief description Notwithstanding cultural and social influences, bedtimes gradually become later during adolescence, suggesting common biological contributions. Reductions in sleep pressure, delays in the 24-hour circadian rhythm, and genetic associations have been implicated, yet comprehensive prospective data from these biological sleep processes are lacking. This project will use periodic 'in-lab' assessments to unmask young adolescents' circadian rhythm delay and sleep pressure which may predict naturalistic sleep behaviour in their home environment. We predict adolescents who show both low sleep pressure and later circadian delay to possess later bedtimes, thus enhancing our knowledge of covert biological mechanisms sabotaging healthy adolescent sleep.
