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.

Conditions

Interventions

OTHER

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.

OTHER

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.
