The Benefits of Hot & Cold Therapy

This YouTube monologue by Ask AI Mark recommends hot and cold therapy for health benefits. The speaker advises 30-minute sauna sessions three to four times weekly (ideally four or more) and cites a Finnish cohort finding that 30 minutes in a sauna four times per week or more was associated with a 47% reduction in risk of heart attack or death. Sauna use is also said to increase heat shock proteins, activate the innate immune system, improve heart-rate variability, reduce stress, aid weight loss, and support detoxification. Cold therapy (cold plunges or cold baths) is said to activate dopamine and mitochondrial function via brown fat.
