My reasoning was that it emit all infrared even visible red light. It worked really well for me. Got my eczema under control after a few days at 1h/day. But from what I saw in the research papers the inflammation is from cellular respiration (affect all the body) and the results of this inflammation can manifest in all kinds of ways. You can also feel it, it’s soothing, much more than just a more heated room. I think that we used to have that infrared before with fireplaces in colder climate, but now it’s almost all gone.
