How daily light affects migraines and sleep

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Over eight weeks, participants will have their daily light exposure, sleep, and migraine characteristics monitored to link real-world lighting patterns with headache outcomes. The first four weeks serve as a baseline observational period tracking natural behaviors, while the second four weeks introduce an ambient lighting condition to alter typical exposure. Data collection will include daily symptom logs and objective/light-sensor measurements to capture timing, intensity, and spectral qualities of light exposure. The goal is to relate changes in lighting to onset, frequency, and severity of migraine attacks and to sleep quality.
