Infrared saunas use radiant heat at infrared wavelengths to heat the body directly rather than heating ambient air. The category spans near-infrared (NIR, deeper tissue penetration claims), mid-infrared, and far-infrared (FIR, the most-installed variant). Different from traditional Finnish steam saunas in mechanism + heat profile.
