Full Spectrum Infrared vs Far Infrared Saunas.
The use of the term "full spectrum infrared” is a marketing tactic used by sauna manufacturers that cannot achieve the purity of infrared output in their saunas to match the Relax far infrared sauna. Far infrared is the form most absorbable by the body. For example, far infrared is used in baby incubators in the hospitals, it is also used for chicken egg incubators. The Relax sauna uses the same far infrared generators that are in the Sky-Eye FDA approved medical grade far infrared lamp.
The Relax sauna generates 95-98% pure far infrared. Other saunas on the market do not have the technology to put out this level of purity and so they simply call it "full spectrum" infrared. Near infrared is the harsher form that some call "toaster oven" or “hair dryer” energy. Your body cannot absorb it as readily and so it heats the skin more rather than penetrating the body like far infrared does.
We have many customers who have owned other infrared saunas and then purchased a Relax sauna after trying one out at a show or at our store.
