How does the full spectra infrared sauna work?

​

The sun’s spectrum of electromagnetic radiation has an entire portion that is made up of near- mid- and far infrared—which we humans feel as heat. Each portion of the electromagnetic spectrum of light serves its own purpose—gamma rays are used to kill cancer cells, visible light allows for us to see, and infrared allows us to feel heat.

​

Why is a full spectrum infrared sauna so good for you?

​

There are three levels of infrared—near, mid, and far—that each resonate with the subcutaneous fat layer of the human body producing different healing responses. Let’s take a look at the three kinds of infrared light and their benefits in an infrared sauna:

​

Near Infrared: Healthy cell immunity, wound healing, skin purification and pain relief.

Near infrared wavelengths have a lower micron level and a resulting shorter wavelength which mostly penetrates the epidermis layer of the skin. This makes it a very safe choice for the improvement of cell health, the renewal of skin, tissue growth and wound healing.

​

Mid Infrared: Pain relief, improved circulation and weight loss.

Mid infrared wavelengths penetrate deeper into the body than near infrared and are therefore good for increasing circulation and blood flow. When used on a consistent basis, mid infrared sauna therapy has been shown to significantly increase blood flow and reduce muscle and joint pain. Healing can occur faster because mid infrared penetrates deeper into soft tissue where inflammation occurs.

​

Far Infrared: Weight loss, detoxification, better circulation, reduction in blood pressure, and relaxation.

Because far infrared sauna therapy heats the body directly rather than simply warming the air, it raises the core body temperature and produces a deep, detoxifying sweat at the cellular level, where most toxins reside. Far infrared also aids in blood pressure reduction & weight loss, as you get a great passive aerobic exercise.

 

Under stressful conditions such as heat shock or hypoxia, increased expression of heat shock proteins protects the cell by stabilizing unfolded or misfolded peptides, giving the cell time to repair or re-synthesize damaged proteins. Their general role as molecular chaperones, protectors of the proteome, is now central to many areas of active research including aging, neurodegeneration, signaling, immunology and cancer.
