Daily Light Exposure Patterns and Their Associations With Migraine Outcomes and Sleep Quality
Arizona State University
Summary
The purpose of this study is to examine the relationship between daily light exposure patterns, sleep quality, and migraine characteristics in adults with migraine, with and without photophobia, across an 8-week study period.

Interventions
- OtherAmbient Lighting Condition
Application of an optimized ambient lighting condition through placement of a dimmable LED floor lamp in participants' private workspaces to create a standardized workplace lighting environment during working hours. The floor lamp emits white light with a specified spectral distribution and intensity. Participants may adjust brightness for comfort. The lighting system is used solely to modify the ambient workplace lighting environment during the 4-week intervention period.
