IYNAUS (Iyengar Yoga National Association of United States) has published a research paper - "Yoga as a Complementary Treatment of Depression: Effects of Traits and Moods on Treatment Outcome” at https://iynaus.org/research/research.
17 primary participants attended 60-90 minute classes over an 8-week period, approximately 3 sessions a week with a total of 20 sessions. Inversions, back bending, and restorative sequences were taught in a progressive manner in the classes taught by Certified Iyengar Yoga Teachers (CIYT).
Results of the study showed the effectiveness of Iyengar Yoga, in addition to standard medical care, to improve the symptoms of chronic depression. Iyengar Yoga class participants reported significant immediate changes in mood after each class.
