Bathing in hot springs containing low levels of radiation-emitting radium and radon promotes metabolism and normalizes the autonomic nervous system, and is effective for rheumatic diseases, high blood pressure, and chronic skin diseases. In addition, recent domestic and international research reports that the emitted γ (gamma) rays have the effect of activating the secretion of beneficial hormones in the human body, and the effectiveness for the prevention and treatment of leukemia and cancer is attracting particular attention.
