Infrared Sauna Therapy heat is actually a particular kind of light. It’s one of the areas of the electromagnetic spectrum invisible to the naked eye. Completely harmless, you might feel far infrared heat from sources such as fires, radiators, and the sun (without the harmful ultraviolet waves that cause sunburns).
Just as visible light has a range of wavelengths (running from red to violet), so does infrared light, which runs from shorter wave infrared to medium and long wave infrared. As many health studies have shown, far infrared heat is the most beneficial in an infrared sauna, penetrating deeper into the skin, increasing circulation, and helping to detoxify the body of harmful toxins.
Infrared saunas differ from traditional saunas because they operate at a temperature of 30-60°C, compared to a traditional sauna that operates at 85-110°C. This allows you to be able to breathe comfortably and enjoy the benefits for extended periods of time. Because the infrared rays safely and comfortably penetrate the skin up to 6cm deep, even your organs and deep tissues are stimulated. This induces sweating 2-3 times as much as a conventional sauna.
