[Heat therapy in chronic venous insufficiency of the legs]

Water cures have long been advocated for venous and lymphatic disorders. Spa therapy combines hydrotherapy, physical therapy and education. Immersion increases central blood volume, diuresis and natriuresis. These effects are independent of the mineral characteristics of the water. Hydrotherapy is viewed as a complementary treatment of venous and lymphatic insufficiency whatever its stage of development; but this has not been formally proved.
