As a physician with almost 20 years of experience in health care, I can honestly say that cold plunges should be regulated. Section R392-302-33 of the Utah regulatory code already outlines the specific use of hydrotherapy pools. In addition to normal pools regulations, hydrotherapy pools are “exempt from all other requirements of R392-302, only if use of the hydrotherapy pool is restricted to therapeutic uses and is under the continuous and direct supervision of licensed medical or physiotherapy personnel.”
