Summary

This trial aims to investigate why some people have delayed sleep wake phase disorder (DSWPD). Researchers will study if individuals with DSWPD have changes in their biological clock and how they respond to light

Who is the study for?
This trial is for individuals diagnosed with delayed sleep wake phase disorder (DSWPD), living at high altitudes like Denver or higher, and have a body mass index (BMI) that's normal to moderately overweight. It excludes those with psychiatric disorders, other sleep disorders, current medication use, or recent medical conditions.
What is being tested?
The study aims to understand DSWPD by comparing circadian rhythms and light sensitivity in patients versus healthy controls. Additionally, it will evaluate a new blood test method designed to predict circadian rhythms.
What are the potential side effects?
Since the interventions involve assessments rather than medications or invasive procedures, significant side effects are not expected. However, discomfort from blood draws or potential eye strain from light sensitivity tests may occur.
