Reflexologists believe the entire body is mirrored on the feet and hands. Foot and hand reflexology is a scientific art based on the premise that there are zones and reflex areas in the feet, and hands, which correspond to all body parts. The physical act of applying specific pressures using thumb, finger, and hand techniques, results in stress reduction, which causes physiological changes in the body. A primary benefit of reflexology is relaxation. Relaxation through reflexology may help the body to balance any kind of stress it is experiencing.
