Hydrotherapy, or water therapy, is the application of water to initiate a cure. All three forms of water (liquid, steam, ice) can be used therapeutically.  The goal of hydrotherapy is to improve the circulation and quality of the blood. This is important because blood delivers nutrients to — and removes wastes from — tissues and organs. If circulation is poor or slow, healing nutrients cannot be delivered and toxins cannot be removed, which causes degeneration of the tissues and organs. By improving the quality of blood, more nutrients are available for cells to use and toxins are managed more efficiently.
