A new study from Boston University indicated that yoga, combined with breathing exercises, really improves symptoms of major depressive disorder. It was the first study to try to identify the optimal “dose”/duration of yoga practice. Participants were split into two groups: one did three 90-minute Iyengar yoga classes and four 30-minute breathwork sessions per week, while the other did two 90-minute Iyengar yoga classes and three 30-minute breathwork sessions per week. For both groups, sleep quality, energy, positivity, and anxiety and depression symptoms significantly improved within a month—and significant additional improvement was observed at three months.
