Infrared sauna is the contemporary and effective expression of an ancient health practice – the application of heat for both general health and to treat specific ailments. The positive health effects were known as long ago as the ancient Greeks, whose physicians would induce slight fevers to fight a number of different illnesses.


Infrared technology itself didn't appear until the end of the 1800s when Dr. JH Kellogg of Battle Creek Michigan invented something that he called an electric light bath. The cabinet, which Kellogg first displayed a version of at the 1893 World’s Fair in Chicago, was sold all over the globe, with some reports saying that German doctors used the technology to cure the king of England of gout, a development that led to the king having the light bath installed in Buckingham Palace. 

The technology for far infrared saunas wouldn’t come until many years later. In the sixties NASA had been doing research into far infrared for the space program, and had discovered how to produce far infrared rays. It was a Japanese doctor, though, who received the first patent in 1965 for a ceramic far infrared heater, which he began to use for healing in the same way one would use a near infrared or traditional steam sauna. Until this point, no one had been using far infrared heat in a sauna setting. For the next 14 years, doctors in Japan were the only ones using this technology, until 1979, when the product was finally released for public use. The technology eventually came to the United States in the 1980s, and it has continued to be refined and made more effective since then.

studies on infrared sauna therapy


heart health

Jama Internal Medicine, April 2015

Journal of Environmental Public Health, Feb. 2012

Sauna sessions can purify the body from the inside out, eliminating compounds such as PCB’s, metals and toxins that are stored in fat cells, which can undergo lipolysis and release toxins upon exposure to infrared-based heat.

physical recovery

Springerplus, Apr. 2015

Deep penetration of infrared heat, low temperature, and light humidity all made FIRS at least slightly beneficial for helping men relax and their muscles recover after endurance training.


skin rejuvenation

Journal of Cosmetic and Laser Therapy, Dec. 2005

Significant improvements in skin appearance were experienced after 12 weeks of sauna skin therapy using near-infrared technology.  Participants experienced a reduction in wrinkles and crow’s feet, and improved overall skin tone, including softness, smoothness, elasticity, clarity and firmness.


headache relief

Journal Alternative Complementary Medicine, Feb. 2015

Regular sauna bathing is a simple, self-directed treatment that is effective for reducing headache pain intensity in chronic tension type headaches.


Clinical Rheumatology, Jan. 2009

This pilot study showed short-term improvement of pain and stiffness, and a trend towards long-term beneficial effects in patients with rheumatoid arthritis.


Journal of Human Kinetics, Dec. 2013

After sauna sessions, an increased number of white blood cells, lymphocyte, neutrophil and basophil counts were reported in the white blood cell profile, showing that sauna use stimulates the immune system.
