Infrared Therapy Overview

What is Infrared Therapy?

Out of all the invisible rays that emanate from the sun, including infrared and ultraviolet wavelengths—far infrared is well known to our bodies because we actually produce it. As it casts upon us, far infrared penetrates deeply into the skin to help dissolve unwanted substances that have accumulated in the body, revitalizing your cells and metabolism, while providing all the healthy benefits of natural sunlight without any of the dangerous effects of solar radiation.

Far Infrared & Full Spectrum Infrared: What’s the Difference?

Far Infrared

Far infrared waves penetrate into our body and activate the sweat glands. The sweat glands are one of the tools that the body has at hand to eliminate toxins. The skin is actually the largest organ of the human body and has been called many times; “the third kidney” because of its ability to discharge large amounts of waste material through the sweat glands. It is one of the best mechanisms the body has for elimination. Bring the benefits of an infrared sauna into your home with a new Clearlight® infrared sauna.

A research paper that was published decades ago by researchers S.Inouye and M. Kabaya showed that far infrared has the ability to cause a vibration in human tissue if wavelengths similar to the ones produced by the body are introduced. This is similar to the effects demonstrated in infrared spectroscopy. When introduced in the proper wavelengths of 9.3 to 9.4 microns, water molecules can begin to vibrate. This vibration reduces the ion bonds of water and the eventual breakdown causes encapsulated gasses and other toxic materials to be released to be eliminated.

Full Spectrum Infrared

Full spectrum refers to the entire infrared spectrum: near infrared, mid infrared and far infrared.

Near Infrared: the shortest wavelength absorbed just below the surface of the skin creating a sweat that promotes healing and revitalization. 


Mid infrared: a longer wavelength that can penetrate deeper into the body’s soft tissue increasing circulation, releasing oxygen to reach injured areas. Both near and mid infrared range from 0.75 – 5.5 microns and enhance the benefits of far infrared. 


Far infrared: the longest wavelength which penetrates the fat cells causing vasodilation, where the fat cells vibrate to expel toxins, resulting in the greatest levels of detoxification and stimulate your metabolism to aid in weight loss. The far infrared rays consist of similar wavelengths as those emitted naturally by the human body. This is one potential explanation of why many feel energetically rejuvenated and balanced from contact with far infrared waves. It is also believed that far infrared waves help improve blood circulation and recovery from fatigue.

With the deeper penetration, full spectrum infrared will raise your core body temperature faster, aids in wound healing by bringing more blood to the affected area, helps reduce inflammation, and much more. We estimate 10-15% additional benefit from a full spectrum sauna. With the addition of near and mid infrared, you will get the maximum benefit from your Clearlight® sauna.

The Research Behind Infrared

Release of Toxins: A research paper published decades ago by researchers S.Inouye and M. Kabaya, found that far infrared has the ability to cause a vibration in human tissue if wavelengths similar to the ones produced by the body are introduced. This is similar to the effects demonstrated in infrared spectroscopy. When introduced in the proper wavelengths of 9.3 to 9.4 microns, water molecules can begin to vibrate. This vibration reduces the ion bonds of water and the eventual breakdown causes encapsulated gasses and other toxic materials to be released and eliminated.

Treatment for Ailments: For years, the healthcare industry recommended infrared heat lamps as a source of infrared therapy but the lamps were cumbersome, extremely hot and difficult to maintain at a constant temperature. Today, many healthcare professionals use infrared heaters to treat a variety of diseases throughout the world. Clearlight infrared saunas use our state-of-the-art True Wave™ heaters.

Raising your Core Body Temperature: The efficacy of infrared waves is very broad and the subject of recent study by NASA. Among the infrared waves, the far infrared rays, which have a wavelength of 6-12 microns, are especially good for the human body. These waves have the potential to penetrate 1.5 to 2 inches or more into the body allowing for deep heat and raise your core body temperature from deep inside. The deep heat of far infrared is why scholars believe that the Ondol (traditional warm floor of Korea) is good for health because the materials for the Ondol are stone and earth, both of which radiate far infrared waves when heated.

Why Infrared Technology?

Infrared heat is all around us, and radiant far infrared is essential for human life. The human body emits and receives infrared heat in the far infrared band. Other surfaces, like a warm street or heated vending cart, give off infrared in the middle and near infrared band. This side-by-side comparison of a photo and image showcasing infrared heat, shows that everything emits and receives infrared heat. 

Do you want to experience far infrared heat right now? Take your hands and put your palms together. Move your hands about 1/2 an inch apart. You will feel warmth emanating from your palms. This is far infrared heat very similar to the infrared heat emitted from our True Wave™ heaters.

Why Infrared Heat is Better Than a Traditional Sauna

Traditional saunas raise the temperature of the air to a very high level within the chamber to warm the body, contributing to difficulty breathing for some people in this extremely warm air. Infrared saunas work differently. Instead of heating the air within the enclosure, infrared saunas heat the body directly with temperatures adjustable and averaging a comfortable 100°F to 130 °F. These lower temperatures allow you to sweat faster with better tolerance of a longer sauna session (20-45 minutes and repeatable once or twice a day for maximum benefits). By warming the body in the same manner as natural sunlight, infrared heat therapy utilizes the wavelength of the visible and non-visible light spectrum of sunlight to heat the body normally with only 20 percent of the energy used to heat the air, leaving the rest of the energy to heat the body to allow the radiant heat to penetrate deep below the skin, and produce a gentle warming inside the body. The result is deeper tissue penetration and greater therapeutic benefit, having the body perspire and receive all of the healthy benefits—leaving you feeling invigorated while avoiding the harmful and extremely hot air of a traditional steam sauna.

Why True Wave™ Provides the Best Sauna Experience

Tests have shown that the energy output of our True Wave™ far infrared heaters is tuned so closely to the body’s own radiant energy that our bodies absorb as much as 93% of the far infrared waves that reach our skin. By comparison, conventional saunas must rely only on indirect means of heat: first, on convection (air currents) and then, conduction (direct contact of hot air with the skin) to produce its heating effect. Your Clearlight Infrared Sauna is best used at temperatures between 100° to 125°F versus 180° to 220°F for traditional hot-air saunas. Since conventional saunas require 30 to 90 minutes of warm-up before use, electricity costs are reported to be a lot higher than those of Clearlight Infrared Saunas which are ready to use in 10-15 minutes.
