Physical Medicine includes massage, hydrotherapy, sauna, exercise and peat therapy. There are two ways physical medicine works. First, it restores structural soundness to the skeletal system, joints, and soft tissue. In addition, it builds immunity and supports healing and detoxification. Hydrotherapy is one of the oldest forms of medical treatment. It involves the use of water applications at varying temperatures to stimulate the body's inherent healing abilities. It is a noninvasive, economical and effective therapeutic approach that acts to stimulate the immune system, facilitate detoxification and promote lymph drainage and circulation. Exercise therapy involves basic stretching and strengthening of muscles to improve and maintain health.
