Full Spectrum
Infrared Technology


Infrared is an invisible wavelength of therapeutic light, experienced as heat, that safely penetrates human tissue to raise core body temperature.


Infrared heat is very gentle and healthy for all living things.

Its medical-grade quality is used by various physicians, and it is even used to warm babies in the hospital. Unlike traditional saunas, which solely heat the air around you and operate in excess of 200°F, Infrared heat warms the body within you on a cellular level and is effective at a more comfortable temperature, between 100°-145°F, producing a deep sweat composed of 20% toxins as opposed to just 3% toxins with a traditional sauna.


“I absolutely love this place. The sauna experience is fantastic. Relaxing, detoxifying, soothing...I can’t say enough good things about it.”

Pure Sweat + Float Studio's industry-leading, infrared wavelengths by Sunlighten provide an abundance of health and healing benefits.



Sweating is the body's natural and safe way to eliminate toxins. Far infrared (FIR) wavelengths amplify this process by reaching deepest into the body, where toxins are stored, breaking them apart so they can be released through sweat. By heating the body directly on a cellular level, FIR raises core body temperature and stimulates the sweat glands, resulting in a deep, detoxifying sweat 7 to 10 times greater than a conventional sauna. Infrared Therapy has been helpful in reducing symptoms of various autoimmune diseases, including Hashimoto’s, Rheumatoid arthritis, and Lyme disease, as well as effective in reducing symptoms caused by environmental toxins, including mold and mercury toxicity.


Near Infrared (NIR), the shortest wavelength, targets the epidermis and dermis layers of the skin, stimulating collagen production and improving its appearance. NIR therapy  reduces wrinkles and scars, makes skin look radiant, firms and improves skin tone and elasticity, and has also been effective for the treatment of acne, eczema, and psoriasis. Regular use may also help reduce cellulite trapped beneath the skin. 


Our Solocarbon® heaters are clinically shown to lower blood pressure via 30 minute sauna sessions three times a week. Repeated infrared treatment improves impaired blood vessel function in patients with high blood pressure, diabetes, and high cholesterol.


Infrared saunas are an effective therapy to treat joint, muscle, and arthritis pain. Mid infrared (MIR) wavelengths specifically penetrate the body’s soft tissue, where inflammation occurs. MIR helps expand blood vessels and increase circulation, so more oxygen can reach injured areas of the body, reducing inflammation and swelling while promoting cellular repair. This, in turn, alleviates pain and speeds the healing process. 


Studies have shown that an infrared sauna session can burn up to 600 calories, as sweating increases heart rate, cardiac output, and metabolic rate. Regular infrared therapy has also been beneficial in reducing belly fat in just three months.


Near Infrared (NIR) therapy, delivered directly into body tissue with LED light, has been clinically shown to successfully  increase cell health and tissue growth.
