I don’t see any problem as exposure to this level of energy is well within standards of health and safety. I would think that the therapeutic benefits of the infrared sauna and the electromagnetic potential of the Mag-Volt would compliment each other. You could experiment and see what you think and let us know. Or play it safe and not wear the Mag-Volt when in the sauna. I tend to take the “try it and see what happens” approach.
