About Far Infrared

What is far Infrared heat?

Radiant heat is simply a form of energy that heats objects directly through a process called conversion, without having to heat the air between. Radiant heat is also called infrared energy or IR. The electromagnetic spectrum is divided into three segments by wavelength, measured in microns or micrometers (a micron = 1/1,000,000 of a meter):

0.076 to 1.5 microns = near infrared;
1.5 to 5.6 = middle or intermediate infrared;
5.6 to 1000 = far infrared.

The far infrared segment of the spectrum occurs just below visible light, in the energy spectrum. This band of light is not visible to human eyes but can be seen by special cameras that translate infrared into visible colors.

We can, however, feel this type of light, which we perceive as heat. The sun produces most of its energy in the infrared segment of the spectrum. Our atmosphere allows infrared rays - in the 7 to 14 micron ranges - to safely reach the earth’s surface. When warmed, the earth also radiates infrared rays in the 7 to 14 micron bands with its peak output at 10 microns.

The infrared heat produced by infrared saunas, such as the SeaMax Far Infrared Sauna is similar to the heat from the sun.

Our tissues normally produce far-infrared energy and burn it as fuel to keep us warm and use it for tissue repair. Tissue production of infrared energy is associated with a variety of healing responses. At times, the infrared energy in our tissues may require a boost to a higher level to insure the fullest healing possible for tissue repair.

Dr. Tsu-Tsair Oliver Chi, when summarizing how infrared devices are attuned to the human body, reported that our body needs an infrared boost and so selectively absorbs infra-red energy waves. After boosting a tissue’s infrared energy, the remaining rays pass onward harmlessly. This phenomenon is called "resonant absorption."

Our bodies naturally radiate far infrared energy through the skin at between 3 to 50 microns in order to keep us warm. Our hands emit far infrared energy between 8 to 14 microns. Palm healing, with a 3000 year history in China, is based on the natural healing properties of far infrared. Native American Indians used sweat lodges for cleansing and purifying, recognizing the health benefits of sweat as well.

Far infrared heat is a form of naturally occurring energy that heats objects by gentle infrared radiation heat, instead of conducting heat through the surrounding air. Far infrared is a safe method of heat transfer, which is used by hospitals in infant incubators to keep newborns warm and by physicians to promote healing. Far infrared heat does not require any medium in order to heat an object, as it can even transfer heat across a vacuum or space. This is why the sun’s radiation of far infrared energy is so efficient at heating the earth from so far away.

Far infrared radiant energy directly penetrates the body’s tissues to a depth of over 1.5 inches. The energy output of Seamax sauna’s therapeutic heating elements are tuned to the human body’s own radiant energy so that our bodies absorb as much as 93% of the infrared waves.

Strict quality control ensures that SeaMax ceramic infrared heaters have achieved the highest standards for technical functionality and aesthetic workmanship. Our therapeutic grade far infrared heaters are made from a unique ceramic formula, carefully formed into a convex to produce radiant heat output in the 5.6 –14 micron wavelength range, for maximum absorption by the human body. Unlike the sun’s radiation, the radiant heat from a Seamax heater does not contain Ultra Violet or other harmful radiation. Using technology developed by NASA, radiant heat from a Seamax patented therapeutic far infrared heater is very efficient, ensuring your body directly absorbs as much as 93% of the heat generated. The Seamax saunas uses about the same amount of power as a standard toaster to operate, and is therefore much more cost efficient than a traditional sauna. The SeaMax infrared thermal system helps to generate two or three times the sweat produced in a traditional sauna, thereby producing a greater effect and also saving time. A Seamax sauna plays a pivotal role in weight control and cardiovascular conditioning.

Our far Infrared sauna burns 400 – 900 calories in just one 30-minute session!

Here are how many calories a 150-pound person normally burns up in 30 minutes of exercise:



Rowing (peak effort)


Swimming (crawl stroke)




Tennis (fast game)


Chopping Wood


Cycling (10 mph)


Golfing (without a cart)


Walking (3.5 mph)




Vigorous Racquet Ball


Marathon Running
