Heat Without Fire: A Brief & Dark History of Infrared Sauna

from Badii Talk: Thermal Bathing and Sauna Culture · host Sarah Spoto

I went into this episode on infrared saunas with an open mind despite my bias toward traditional sauna and its deep cultural roots. Infrared may lack that culture (and the heat), but for many in the US and UK, it’s an accessible entry point into sauna.What I found surprised me: a dark past tied to pseudoscience, eugenics, and questionable marketing. Infrared saunas themselves aren’t inherently bad, but they do reflect some of the more problematic sides of modern American wellness culture.In this episode, I cover:A brief history of infraredThe appeal and potential (the good stuff)The science…and lack thereofHow in many ways infrared represents the dark side of American wellness culture: a toxic mix of individualism, commercialism, and pseudoscienceHow to strike a balance where infrared can play a valuable role as a path to a traditional sauna practiceI’m not a medical professional or scientist, but I’ve done my best to represent the science as shared to me by experts. And I’ve tried to share the information in a way that I hope is more digestible for us laypeople.  As such, thank you for giving me grace with any medical and scientific information I’ve summarized.I’ve leveraged a number of sources for today’s episode.
