Signature Far Infrared Saunas from Sunlighten™ are the most effective far infrared saunas available. Using Solocarbon heat as the active ingredient, Signature offers the maximum therapeutic results. Solocarbon is the only heater on the market clinically shown to raise core temperature, lower blood pressure and aid in weight loss. This is one of the reasons more doctors recommend Sunlighten over any other sauna brand.
The most important element in an infrared sauna is the heater emissivity rating, which determines how efficiently the infrared heat is emitted. High infrared emissivity is the key to the infrared benefits! With generic carbon blend heaters, you’ll get an emissivity rating that’s significantly lower than Solocarbon heaters, making ours the most effective far infrared heater on the market.
