Summary

This study looks at whether being awake during the late-night hours (2:00-4:00 AM) can worsen mood, increase hopelessness, and impair decision-making in people who have had suicidal thoughts in the past six months. Researchers will monitor 90 adults in a lab and at home under different sleep conditions. The goal is to understand the mechanisms behind nighttime suicide risk, not to test a treatment.
