Sauna Therapy for Detoxification and Healing is a 2016 book, so one would think its criticism of Far Infrared Saunas is current. Be careful with exposure to EMFs. I'm trying to find an EMF/Gauss meter.

I found this YouTube video from Alex Tarris and I gave it a thumb up.
I have a Therasauna, and it has a serious design flaw. It's their small, two-person model, and the flaw is uneven heating. My back would be roasting hot because there are two heaters immediately behind me. But, there's only one heater directly in front of me, and it's a couple feet away and has the same power as the heaters in back; as a result, my front would be freezing cold. I covered the glass door with aluminized bubble wrap insulation, but it didn't make much difference. To fix it, I bought two similar ceramic heaters and mounted them right above the two front heaters, and instead of the sauna's 160 watt heaters, I used 350 watt heaters. The added heaters run off a different circuit than the sauna, so there's no overload. Now, if I sit a little bit away from the back heaters, the radiant heat feels about the same, front and back.
I'm a big fan of sauna. Had a number of books on it. Has helped me in many ways, from preventing stiff muscles after workouts, reducing winter head colds in northern climates, clearing my chronic sinusitis, etc. But here in perpetually warm, often very hot South Florida the need has declined.
I did see a demo of infrared sauna at a Fort Lauderdale home show at the convention center. I wasn't terribly impressed, judged the experience not superior to more traditional methods, if perhaps quicker with less maintenance. VERY traditional is fire-heated rocks, but electric resistance heating elements under rocks will do.
I like to breathe the hot air, sometimes scented with aromatic woods on the rocks. It's the hot air that can kill the rhinovirus in your nasal passages, evidently reducing incidence of head colds, and easing those you already have.
One thing I like about FIR saunas over traditional saunas is that they don't get very hot inside, so my head doesn't get overheated. But, all that really happens in a FIR is a lot of sweating; it doesn't ramp up the heart rate like a traditional sauna. Three evenings a week, I do sauna with friends who have traditional wood-fired saunas, and I sleep great afterwards; I don't get that effect from a FIR sauna.
