I decided to explore the health benefits of acute heat exposure in the form of saunas, baths, and steam rooms for one main reason: the sauna is a near-universal human tradition, and I’m always curious about those. Are all these many billions of people across time and space sitting in heated rooms for the heck of it? Luckily, we don’t have to guess: extensive research into the health benefits of saunas, steam baths, IR saunas, and other forms of acute heat exposure confirms that the human universal of getting really, really sweaty, hot, and steamy on purpose has merit.
