Baths were generally taken in the form of a prescription from a physician, and carried out in a suitable public facility built around a thermal pool. Hydrotherapy is a cornerstone of Naturopathic medicine. The mechanics of water is both simple and complex. The circulation of water through the biosphere unites all water systems including the animated bodies of all living things. The solar influence on the water body of the earth is the cause of global weather patterns, water distributions, and the flow of life.
Water is the liquid crystal of all biology.
Theodore Schwent, founder of the Institute of Flow Sciences has shown in amazing photographs the similarity between various water flow patterns and organic life structures. It is the mediator between the two, and its surface provides a common frontier in nature where they meet. Death is continuously being overcome there. Primarily water has a thermal quality which acts upon a life form to cause a reflex response of flow, a movement, a circulation. Secondly, water is a delivery system that provides nutrients and removes toxins.
