Another advantage of healing with Yoga, is that it lets people control a variety of body functions. These include blood pressure, body temperature, heart rate, metabolic functions, and so on and so forth. Skeletal, muscular, endocrinal, and nervous systems then respond in a highly sensitive manner, to ensure proper function and maintain health. For example – when you practice Sarvangasana, the thyroid is really stimulated, or when you practice Sirshasana, the pituitary is stimulated, or when you practice Paschimottanasana, the pancreas is stimulated. Research has shown that, people who regularly practice Yoga, have lower anxiety, are more stress resistant, have normal blood pressure, great heart function, and overall enhanced physical fitness.
