Over several years, we have been carrying out measurements of the relationship between oxidation-reduction potential (ORP) and pH of water samples from many hot springs in Japan and Europe. Unequivocally all showed reductive characteristics. For the present study, we conducted similar measurements of hot spring waters in Taiwan, and our data clearly demonstrate that all possess reductive characteristics as well. In short, although the definition for hot springs differs depending on the country, water characteristics were in all cases reductive. Contrasting this finding, water from 10,000 meters below the seabed, as well as the raw water as the source of mineral waters from spring and underground waters, are in equilibrium (i.e, they are not reductive nor oxidative) From this, we believe that the reductive characteristics of hot spring waters are different from other natural waters that are in equilibrium. It is known that hot spring waters that show reductive characteristics can suppress the formation of skin melanin and improve the elasticity of the skin. Therefore, we believe that hot spring waters from Taiwan, as well as those from Japan and Europe have the property akin to the "Fountain of Youth", for their antiaging effects. Furthermore, we believe that possessing reductive characteristics should be included in the definition of hot spring waters. [ABSTRACT FROM AUTHOR] |
