It was once thought to treat everything from typhoid to tumors, and even general well-being in Roman and Turkish bathe. Today it is relied on as an aid in treating muscular and joint injuries, arthritis, and it is still treating general well-being in modern saunas and private bathtubs. The benefits of hydrotherapy are a result of the principles of buoyancy, hydrostatic pressure and water temperature. The principle of buoyancy of water comes into play when treating muscualar or joint injuries. Physically this relieves the pressure of weight on our joints and muscles, and, the feeling of weightlessness proves to be very relaxing mentally as well as physically The weightless effect of water is also recommended for arthritis sufferers, as it eases joint stiffness and improves the mobility of the joints.
Hydrostatic pressure offers a form of massage that is soothing as well as healing.
Studies at trauma and burn centers have shown that the massaging currents of water gently soothe touchy nerve endings while cleansing the wounds. This massaging action, combined with weightlessness, relaxes tight muscles. It also releases natural pain killers, called endorphins, into our system. It is important to note that a person doesn't necessarily need to be in a whirlpool to enjoy the benefits of hydrotherapy. A large bathtub at home will do fine, as long as one can relax, stretch out and be mostly submerged, depending on the effect you are looking for.
