Full Spectrum Infrared Saunas

About

Full Spectrum Infrared Saunas — Every Wavelength in One Unit Full spectrum infrared saunas emit near, mid, and FAR infrared wavelengths simultaneously, giving you the broadest range of therapeutic coverage available in any infrared sauna. Instead of choosing between wavelength types, you get all three working at different tissue depths in a single session. We carry full spectrum models from Dynamic Saunas , Golden Designs , Maxxus , Finnmark Designs , and Wizzisaunas — many with built-in red light therapy . Every order ships free with 0% APR financing.

What Makes Full Spectrum Different Most affordable infrared saunas are FAR infrared only , meaning they emit wavelengths in the 5.6–15 micron range. FAR infrared is excellent for core heating and heavy sweating, but it's only one piece of the spectrum. Full spectrum saunas add two more wavelength bands: Near infrared (0.7–1.4 microns) — The shortest wavelengths, closest to visible red light. Near infrared is absorbed at the skin surface and just below, making it most relevant for skin health, cell renewal, and wound healing. This is the same wavelength range used in many red light therapy panels . Mid infrared (1.4–5.6 microns) — Penetrates deeper than near infrared, reaching into joints, muscles, and soft tissue. Mid infrared is associated with improved circulation and pain relief in deeper structures. This wavelength is the hardest to find in standalone panels, which is one reason full spectrum saunas are popular — they're the most practical way to get mid infrared exposure. FAR infrared (5.6–15 microns) — The longest wavelengths and the deepest penetration (about 1.5 inches into the body). FAR infrared raises your core temperature most effectively, producing the heaviest sweat response. This is the workhorse wavelength for detoxification and cardiovascular
