“Clinical symptoms were improved in 17 of 20 patients after two weeks of sauna therapy. Repeated sauna treatment improves vascular endothelial function, resulting in an improvement in cardiac function and clinical symptoms.” – “Repeated sauna treatment improves vascular endothelial and cardiac function in patients with chronic heart failure.” Kihara, T. et al. Journal of the American College of Cardiology, March 2002.
“Repeated sauna therapy (60°C for 15 min) improved hemodynamic parameters, clinical symptoms, cardiac function and vascular endothelial function in patients with CHF.” – “Beneficial effects of sauna bathing for heart failure patients.” Blum, Nava et al. Experimental & Clinical Cardiology, Spring 2007.
“Increased frequency of sauna bathing is associated with a reduced risk of sudden cardiac death, fatal coronary heart disease, fatal cardiovascular disease, and all-cause mortality.” – “Association between sauna bathing and fatal cardiovascular and all-cause mortality.” Laukkanen, T. et al. JAMA Internal Medicine, April 2015.
“Waon therapy is a form of thermal treatment in a dry sauna maintained at a temperature of 60 degrees C, which differs from the traditional sauna. Waon therapy reportedly improves the hemodynamics, cardiac function, ventricular arrhythmias, vascular endothelial function, neurohormonal factors, sympathetic nervous system function, and symptoms in patients with chronic heart failure (CHF).” – “Waon therapy for cardiovascular disease: Innovative therapy for the 21st century.” Miyata, M. et al.
