Depression

Biological and behavioral indications of sadness, helplessness, and unhappiness as manifested by insomnia, loss of interest in previously engaging subjects, being easily frustrated and irritated, reduced speech and activity and appetite, and uncharacteristically poor performance in multiple areas. In 2019, research by Streeter, et. al. at Boston University confirmed that major depression’s symptoms are somewhat relieved by Iyengar Yoga and breathing exercises. However, no dose-response effect was statistically significant.
