Yoga consists of methods for developing balance and health within our entire being. Originating in India, the name "yoga" means to yoke or join together the gross and subtle energies of our being to attain an experience of wholeness and harmony. The practice of Hatha yoga is designed to open and align the body in such a way that the life force flows freely through the system. Research on the health benefits of Hatha yoga has demonstrated reductions in coronary heart disease risk by reducing blood pressure, stress, and anxiety, as well as increasing self-confidence and strength. Additional studies have demonstrated positive effects of yoga on hypertension, asthma , and mood enhancement. Studies on yoga in healthy people have also shown significant positive results including reductions in blood pressure, heart rate, respiratory rate, body weight, autonomic arousal, as well as lower scores on excitability and aggression and higher life satisfaction scores.
