Summary
This study found that both the timing and duration of screen use independently affect sleep quality and daytime functioning in adolescents, with evening use beyond 2 hours and any night-time use being particularly harmful. For lighting and digital environment design, this suggests that blue-light-rich screens should be restricted or filtered in the evening hours, and usage cutoffs should be enforced before bedtime.
Key Findings
- More than 2 hours of evening screen use is associated with adverse sleep outcomes in adolescents.
- Any night-time screen use is associated with further sleep disruption and impaired daytime functioning.
- Both timing and duration of screen use independently contribute to negative sleep effects, not just total daily screen time.
Categories
Sleep & Circadian Health: Screen timing and duration both affect adolescent sleep quality and circadian disruption.
Student Learning: Adolescent daytime functioning is impaired by evening and night-time screen use, with implications for school performance.
