What is an Infrared Sauna and the Benefits?

Updated: Aug 24, 2022

What is Infrared?

Infrared light is part of the sun’s invisible spectrum of light that has the ability to penetrate the human tissue. Infrared heat therapy uses these infrared light characteristics to heat the body directly rather than just the air. The experience of an infrared sauna is similar to sunbathing, which gives you the radiant heat that is all your own. The infrared heat penetrates your skin, giving you that wonderful natural warmth. Unlike sunbathing, infrared heat therapy is completely healthy and safe. You can relax in an infrared sauna, and it will never cause your skin to burn.

Infrared saunas increase the body’s core temperature thus resulting in a much deeper, more detoxifying sweat from the cellular level of the skin where many toxins are housed. Conventional hot rock/steam heat saunas heat the air with steam, which can often be unbearably hot and will cause you to only sweat at the surface of the tissue. Steam also makes the air difficult to breathe. An infrared sauna uses soothing dry infrared heat that is well ventilated and extremely comfortable and relaxing. Infrared heat therapy has also been proven to assist with weight loss, pain relief, improved circulation, and skin rejuvenation.

Safety of Infrared

You can be exposed to infrared heat for hours and it will never cause your skin to burn. Infrared heat is completely healthy and safe for all living things. In fact, infrared heat is so safe it is used in hospitals to warm newborn infants.

Infrared waves, reflected from the Sunlighten sauna to the body, provide concentrated radiant energy, similar to that from the sun. When any tissue in the body is exposed to infrared waves, whether radiated by sunlight or reflected by specially coated fabrics or panels, there is a rapid increase in warmth which can be shown by thermography. This heat plus the activation of several other response mechanisms stimulates the healing processes.

For example, infrared waves from Sunlighten saunas:

1. Increase blood flow by promoting dilation (expansion) of the micro-circulatory system of capillaries.

2. Reduce muscle spasms as muscle fibers are heated.

3. Remove toxins from the site receiving infrared waves.

4. Assist in the reduction of swelling and inflammation by improving lymph flow.

5. Reduce soreness through direct action on both free nerve endings in tissues and on peripheral nerves.
