Sleep Deprivation & Adolescence (2010)

This study investigated sleep deprivation & adolescence. Later parent-set bedtimes and correspondingly shorter sleep duration appears to be related to the development of depression in adolescence, a cross-sectional analysis showed. In the sample 24% of adolescents were shown to experience depression when going to sleep at midnight or later. In addition to depression, adolescents with later bedtimes also had a greater risk of having a 20% increased incidence of suicidal thoughts, compared with adolescents who went to bed before 10:00pm.
