First seen Jun 25, 2026 · Last updated Aug 14, 2026 · Updated 3 times
Summary
This study looks at how physical activity, sleep, and light exposure relate to mood in people with bipolar disorder, major depression, or no mood disorder. Over two years, participants wear activity monitors and complete smartphone diaries for up to 20 days at a time. The goal is to better understand these connections, which could lead to improved lifestyle-based strategies for managing mood disorders.
