Sauna therapy has been used for hundreds of years in the Scandinavian region as a standard health activity. Studies document the effectiveness of sauna therapy for persons with hypertension, congestive heart failure, and for post-myocardial infarction care. Some individuals with chronic obstructive pulmonary disease (COPD), chronic fatigue, chronic pain, or addictions also find benefit. Existing evidence supports the use of saunas as a component of depuration (purification or cleansing) protocols for environmentally-induced illness. While far-infrared saunas have been used in many cardiovascular studies, all studies applying sauna for depuration have utilized saunas with radiant heating units. Overall, regular sauna therapy (either radiant heat or far-infrared units) appears to be safe and offers multiple health benefits to regular users.

Far infrared waves penetrate our body and activate the sweat glands. The sweat glands help eliminate toxins. 

The skin is the largest detoxifying 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. 

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

Mid infrared is a longer wavelength that can penetrate deeper into the body’s soft tissue increasing circulation, releasing oxygen to reach injured areas.

​

Far infrared is 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 sun is the primary source of radiant energy, but not all of this energy is beneficial. Although life needs energy from the sun, too much sunlight damages the skin. Infrared heat provides all the healthy benefits of natural sunlight without any of the dangerous effects of solar radiation.

Today, many healthcare professionals use infrared heaters to treat a variety of diseases throughout the world. 

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. 

A research paper that was published decades ago by researchers S.Inouye and M. Kabaya showed that 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.

It is also believed that far infrared waves help improve blood circulation and recovery from fatigue.
Near and mid infrared range from 0.75 – 5.5 microns and enhance the benefits of far infrared. 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.
