Official title

Regulating Mood and Suicidal Ideation With Morning Light Exposure Treatment

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
