Hydrotherapy, formerly called hydropathy, involves the use of water for pain-relief and treating illness. The term hydrotherapy itself is synonymous with the term water cure as it was originally marketed by practitioners and promoters in the 19th century. A hydrotherapist therefore, is someone who practices hydrotherapy.
The healing properties of hydrotherapy are based on its mechanical and/or thermal effects. It makes use of the body’s reaction to hot and cold stimuli, to the protracted application of heat, to the pressure exerted by the water, and to the sensation of the water itself. Nerves carry what is felt by the skin deeper into the body, where it is then vital in stimulating the immune system, influencing the production of stress hormones, improving circulation and digestion, encouraging the flow of blood, and lessening the body’s sensitivity to pain.
