What this trial studies

This study aims to address chronic circadian misalignment and sleep restriction in late adolescents, which can lead to various health issues. Participants will follow a 14-day protocol that includes a stable sleep schedule at home followed by a week in a laboratory setting. The study will assess the impact of bright light exposure on circadian rhythms and sleep onset, utilizing wrist-worn devices and sleep diaries to monitor compliance. The goal is to determine the optimal timing for light exposure to improve sleep quality and overall health outcomes.

Good fit: Ideal candidates are adolescents aged 18-20 who live in or near Chicago, IL.

Not a fit: Patients outside the age range of 18-20 or those not residing in the Chicago area may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved sleep patterns and reduced health risks for adolescents experiencing circadian misalignment.

How similar studies have performed: Previous studies have shown promising results in using light exposure to influence circadian rhythms, suggesting this approach may be effective.
