Not all infrared is the same. The wavelength and intensity of the energy being delivered matter.
Relax Sauna is engineered to deliver 7–14 μm far infrared energy at 40 mW/cm²—rather than simply relying on how hot the sauna feels.
It’s also an FDA Registered Class II Medical Device, a distinction that sets Relax Sauna apart in the infrared sauna market.
So when you’re comparing infrared saunas, look beyond temperature. Ask what kind of infrared energy the technology is actually delivering.
