Sleep in adolescents

Hila Vidal, Tamar Shochat

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Sleep in adolescents is characterized by later bedtime and wake times, curtailed sleep duration, and large differences in sleep patterns between weekdays and weekends. Changes in bio-regulatory sleep mechanisms, including the circadian pacemaker and homeostatic sleep propensity, as well as environmental and psychosocial factors, mainly school start times, contribute to these sleep patterns. Evidence-based expert panels call for adolescents to sleep between 8 and 10h for optimal functioning; however, many adolescents sleep much less than recommended. The negative consequences of inadequate sleep include decreases in mental and physical health, daytime functioning and academic performance. Cultural disparities are also recognized.
