There are two long-believed axioms about adolescent sleep: (1) as children reach adolescence, they go to bed and get up at later hours; and (2) adolescent sleep deprivation is a widespread phenomenon. The National Sleep Foundation’s survey and research, as well as that of others, has established the support for these axioms.1 Adolescent sleep patterns undergo a “phase delay;” the typical upper school student’s natural time to fall asleep is 11:00 pm or later. Despite adolescents needing 8.5–9.25 hours, the average teen gets approximately 7.5 hours of sleep a night; 62% of 9th–12th graders report insufficient amounts (i.e., less than eight hours) of sleep; and only 3% of seniors get “optimal” sleep on school nights. Adolescents do not adjust their bed times in response to changes in the time of day that school begins, so an hour later start time translates to about an hour of additional sleep.
