DOES SIZE OF THE INFRARED HEATER MATTER?
While the surface area of the heater is important, our research has shown that physical size does the dispersion of the far infrared. The problem with the discussion about heater size (surface area) is that it too often gets used as a marketing tool used to exaggerate the effectiveness of the infrared heater. This study and others have convinced us of the opposite: that a variety of wavelengths is most beneficial. This is in part because heaters that emit MEDIUM Wave infrared heat between 1.5 –5.8 microns stimulate the body’s warmth-sensing nerves to produce the most sweat. Longer far infrared heat waves are potentially better at penetrating deeper inside the body tissues. It is our experience that a combination of different infrared wave lengths will produce the best overall results. That’s why we believe that the variety of different wavelengths provided by the heaters within an infrared sauna is more important than the heater size itself.
