Hydrotherapy is an accepted, useful form of symptom treatment for many ailments. The ability to promote relaxation in its many forms is well-established. It can be used effectively, as heat, steam, cold, or in a whirlpool. Heat transferred from hot compresses expands blood vessels, improving circulation. Improved circulation increases the body's ability to confront infection, reduce pain, and generally improve body functions.
Ice packs reduce swelling by constricting blood vessels and therefore reducing circulation.
Room humidifiers help eliminate excessively dry air and promote healthier breathing. The external forms of hydrotherapy are useful, complementary treatments. Internal therapies should never be used without consulting a doctor.
