The Relax Sauna is a VERY LOW EMF Sauna. There is less than .5 mg of EMF everywhere where your body sits in the Relax Sauna. Wooden saunas and inexpensive Chinese-made Saunas have panels all over, which generate EMF. The Relax Sauna generate most of the FIR Energy by bouncing off the Tent Walls (which have silver embedded in it, acting as a mirror and hence NO EMF is generated off the walls.)
It is interesting to note that some of the healing magnets have more EMF than the Relax Sauna Radiators, and that a Wheat Grass Juicer, or a VitaMix will have 6 times the EMF of the Relax Sauna radiator. It is also worthy to note that the Relax Sauna generates about 99% pure Far Infrared Energy, and is therefore more effective in anti-doting EMF than a wooden sauna that generates only 50-60% FIR energy.
