TheraSauna holds a proprietary patent that reduces voltage to the infrared emitters as the sauna cabin reaches the specified temperature. This means that the emitters never turn off during the sauna session, but rather cool down to deliver the longer far-infrared rays rather than having to shut off completely (as with ALL other infrared saunas, in spite of their claims). The effect is a tremendous increase in the amount of far-infrared produced during the sauna session.

As an option we recommend the upgraded MPS SpectraWave(TM) controller that allows you to fine tune the voltage to each emitter zone, giving you further control over the infrared frequency you receive. You can even program sauna sessions a week in advance. This controller also includes the SpectraWave(TM) system which, at the push of a button sends a wave of infrared heat around your entire body by varing the output of the emitters in a circulating pattern. Truly unique.
