A way of life that includes ethical precepts, dietary prescriptions, and physical exercise. Its practitioners believe that their discipline has the capacity to alter mental and bodily responses normally thought to be far beyond a person's ability to modulate them. During the past 80 years, health professionals in India and the West have begun to investigate the therapeutic potential of yoga. To date, thousands of research studies have been undertaken and have shown that with the practice of yogic meditation a person can, indeed, learn to control such physiologic parameters as blood pressure, heart rate, respiratory function, metabolic rate, skin resistance, brain waves, body temperature, and many other bodily functions.
