The Baths of Leuk. The history of the springs of Leukerbad dates back to Roman times. People, even then, were already aware of the therapeutic effect of the thermal water. Today, 1,000,000 gallons of thermal water - up to 124 簞F - flow from the springs and feed 22 thermal pools. Several baths are at the disposal of guests in private hotels, in the Rehabilitation center and in the Volksheilbad, but the biggest public baths are the Leukerbad Therme (previously Burgerbad) and the Lindner Alpentherme. Balneology is the branch of medical science concerned with the therapeutic value of baths, especially those taken with natural mineral waters. Balneotherapy may involve hot or cold water, massage through moving water, relaxation or stimulation. Many mineral waters at spas are rich in particular minerals (silica, sulfur, selenium, radium) which can be absorbed through the skin.
