First seen Jun 26, 2026 · Last updated Aug 27, 2026 · Updated 5 times
Summary
This study tested a new approach: having people with major depressive disorder do 30 minutes of moderate exercise right before a therapy session. 40 adults were split into two groups: one exercised on a stationary bike, the other watched nature videos. The goal was to see if exercise helps people connect better with their therapist and become more active in their daily lives.
