Effect of Morning Light Exposure on Mood
Sponsor: University of Arizona
Summary
Mood dysregulation and suicidal ideation are closely associated with disruption of sleep and circadian rhythms. Moreover, sleep problems and circadian disruption are commonplace features of military life. Critically, specifically timed light exposure plays a powerful role in regulating mood, circadian rhythms, and sleep-wake patterns. Therefore, investigators propose to conduct a large-scale clinical trial on the effectiveness of morning light exposure treatment for improving sleep-wake patterns, emotional and mental health, and suicidal thoughts in military personnel.

Interventions
Active light exposure
Active light at the wave length of 470nm will be emitted for 30 minutes over a 2 week time frame, from commercially available ayo glasses, as a method to regulated circadian rhythm.
Placebo light exposure
Placebo light at the wave length of 578nm will be emitted for 30 minutes over a 2 week time frame, from commercially available ayo glasses, as a control to investigate the regulation of circadian rhythm.
