Far Infrared vs Full Spectrum Saunas: What Actually Changes at the Product Level
Look, if you've spent any time comparing infrared saunas, you've already hit the wall where every spec sheet uses the same three words — far infrared , near infrared , full spectrum — and nobody bothers to explain what they actually mean for the product you're about to spend several thousand dollars on. So let's fix that. This isn't a ranking. Far infrared isn't worse than full spectrum. Near infrared isn't better than either. These are emitter configurations — different technology setups at different price points — and the label on the box tells you almost nothing about which one belongs in your house. First: What Does "Infrared" Actually Mean Here? Infrared is light at wavelengths longer than visible red. You can't see it, but you feel it as heat. The three labels — far, near, full spectrum — describe which portion of that infrared band the emitters in the cabin are producing. That's it. That's the whole distinction at a ...
