This study investigated the effects of sleep restriction (7 nights of 5 h sleep opportunity) on cognitive performance, subjective sleepiness, and mood in adolescents. Compared to having 9h a night to sleep sleeping 5 h for 7 nights, resulted in steady decline of sustained attention, working memory/executive function, and speed of processing. Subjective alertness and positive mood were also impaired. Among the measures evaluated, sustained attention was most affected by multiple nights of sleep restriction. Critically, some neurobehavioral measures did not fully recover even after 2 nights of 9 h sleep opportunity.
