Teens who stay up late: new therapy aims to reset body clocks
NCT ID NCT01828320
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether behavioral therapies could help teens who naturally go to bed late shift to earlier bedtimes. 176 teens with late sleep patterns were given either a combination of therapies (cognitive behavioral therapy, social rhythms therapy, and light therapy) or basic education about sleep. The goal was to see if earlier bedtimes could reduce risks in emotional, behavioral, social, physical, and school-related areas. The study is already completed, and results focus on changes in sleep timing and overall functioning.

Active substance
Cognitive Behavior Therapy for Insomnia, Interpersonal and Social Rhythms Therapy, Chronotherapy, and Psychoeducation
What this could lead to
If successful, these therapies could offer a practical way to help teens shift to earlier bedtimes, potentially improving mood, school focus, and overall health.
What could go wrong
This is a small, completed study with no long-term follow-up, so lasting benefits are uncertain. Results may not apply to all teens, and behavioral changes can be hard to maintain.
