The breathing trick that brings on happy calm

More evidence that deep breathing is a potent healer: People who practiced Sudarshan Kriya, yoga centered on breathing, lowered depression scores by 47 percent in 4 weeks, say scientists in The Journal of Clinical Psychiatry. Focused breathing breaks up negative thoughts and resets an overstimulated nervous system. To do: Sit with your eyes closed and hold your left nostril closed, slowly breathing in and out through your right nostril. Switch sides. Do for 5 minutes twice a day.
