What is the ideal infrared sauna temperature?

The ideal temperature for an infrared sauna according to Rhonda Patrick is approximately 140 degrees Fahrenheit. Infrared saunas operate at lower temperatures compared to traditional saunas, which usually reach around 174 to 179 degrees Fahrenheit. The lower temperature in infrared saunas is still effective for sweating out toxins like BPA, phthalates, mercury, and heavy metals 1.
