Practitioners use a variety of physical methods including applying fixed or movable pressure, holding, or causing movement to the body. Therapists primarily use their hands, but may also use their forearms, elbows, or feet. The basic goal of massage therapy is to help the body heal itself and to increase health and well-being. Massage improves circulation, which increases blood flow, bringing fresh oxygen to body tissues. This can assist the elimination of waste products, speed healing after injury, and enhance recovery from disease. Therapeutic massage can be used to promote general well-being, while boosting the circulatory and immune systems to benefit blood pressure, circulation, muscle tone, digestion, and skin tone. It has been incorporated into many health systems, and different massage techniques have been developed and integrated into various complementary therapies.
