Dr. Marc Cohen reveals a significant oversight in the celebrated Kuopio Ischemic sauna study, which linked sauna use with a marked decrease in all-cause mortality: the critical role of cold exposure. While the research attributes dramatic health benefits to saunas alone, Dr. Cohen points out that in Finland, the practice inherently includes cold plunges—a factor often excluded in Western interpretations. He explains how alternating between hot and cold amplifies cardiovascular benefits, detoxification, and mental resilience. This episode challenges long-held assumptions and offers practical advice for harnessing the true power of sauna and cold therapy.
