Institute,. Research Institute for Health Resort Medicine +, - Abstract We have conducted investigations on the ORP-pH relationship of 2, hot spring water samples (drinking spring waters) from -/ spas in seven European countries including Germany, Switzerland, France, Italy, Austria, Czech, and Belgium,. Through these investigations and comparative analyses of hot spring waters and natural mineral waters in terms of ORP-pH, the following results were obtained. Hot spring (drinking) waters in Europe : + ) Have a reductive characteristic in terms of ORP and a ph value ranging from weak acidity to weak alkalinity.,) Mainly used for drinking. Hot spring waters used for pool or Jacuzzi bathing by the general public are disinfected to assume an oxidative state. -) For drinking, hot spring waters fresh out of wellheads are used without treatment. Contrasted with these drinking hot spring waters that are reductive in ORP, commercial natural waters are at the equilibrium ORP level. Hot spring waters in Japan : + ) Have a reductive characteristic in terms of ORP and a ph value ranging from strong acidity to strong alkalinity.,) Mainly used for bathing. 185
186 -) The practice of therapeutic drinking of hot spring waters is scarcely popular. In contrast to these hot spring waters that are reductive in ORP, commercial natural waters including their source waters are at the equilibrium ORP level. Hot spring waters in both Europe and Japan are characterized in that they are reductive in ORP, whereas commercial natural waters are at the equilibrium ORP level. Considering that hot spring waters are mainly used for drinking in Europe and for bathing in Japan due to di# erences in balneological history between them, we propose widespread use of hot spring waters for both drinking and bathing to bring benefits to the health. A combination of the drinking of and bathing in reductive hot spring waters could suppress oxidation of the internals and skin of the body to provide the e# ect of whole-body anti-aging.
