Sleep regularity in healthy adolescents: Associations with sleep duration, sleep quality, and mental health

This study examined the impact of sleep regularity on mental health and sleep quality in adolescents. Using wrist-worn devices, sleep patterns of 46 adolescents were tracked over six months. Findings revealed that regular sleep during school days is linked to better mental health, including fewer depressive symptoms, while regular weekend sleep correlates with overall improved mental well-being. Regular sleep also led to longer sleep durations, shorter times to fall asleep, and better sleep efficiency. Irregular sleep patterns were associated with daytime fatigue and psychological issues, emphasizing the importance of consistent sleep routines for mental and physical health during adolescence.

Adolescents should aim for consistent sleep schedules, especially during school days, to enhance mental health and sleep quality. This advice is supported by objective data from actigraphy and correlational findings, though the sample size limits broader applicability. sleep regularity, not just duration, should be a focus for parents and educators.
