What this trial studies

This study investigates the effectiveness of brief flashes of light scheduled during sleep to treat Delayed Sleep Phase Disorder (DSPD), a common sleep disruption in adolescents. Participants will be high school students experiencing difficulties with sleep timing and associated daytime disturbances. The intervention aims to realign their circadian rhythms and improve overall sleep quality. The study is conducted at Stanford University, leveraging their expertise in sleep disorders and adolescent health.

Who should consider this trial

Good fit: Ideal candidates are full-time high school students experiencing symptoms consistent with delayed sleep phase disorder.

Not a fit: Patients who sleep only in a prone position or are currently taking medications for sleep disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve sleep patterns and daytime functioning for adolescents suffering from DSPD.

How similar studies have performed: While the use of light therapy is established in treating various sleep disorders, this specific application for DSPD in adolescents is relatively novel.
