About Far Infrared

What is far Infrared heat?

Infrared (IR) light is a radiation with longer wavelengths than those of visible light. Much of the energy from the Sun arrives on Earth in the form of infrared radiation. Sunlight at zenith provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 527 watts is infrared radiation, 445 watts is visible light. The balance between absorbed and emitted infrared radiation has a critical effect on the Earth's climate.

Infrared radiation is popularly known as "heat radiation". Heat is energy in transient form that flows due to temperature difference. Unlike heat transmitted by thermal conduction or thermal convection, infrared heat does not require any medium in order to heat an object, radiation can propagate through a vacuum. Infrared radiant heat is simply a form of energy that heats objects directly, without having to heat the air between. This is why the sun’s radiation of far infrared energy is so efficient at heating the earth from great distance. Radiant heat is also called infrared energy or IR. The 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 region from 8 to 15 microns (µm) is referred to by Earth scientists as thermal infrared since these wavelengths are best for studying the long wave thermal energy radiating from our planet. Infrared radiation can be used as a deliberate heating source. Far infrared is also gaining popularity as a safe natural heating source.  Far infrared is a safe method of heat transfer, which is why it is commonly used by hospitals in infant incubators to keep newborns safe and warm.
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 instruments that can sense infrared energy—such as night-vision goggles, film, or infrared cameras–allow us to "see" the infrared waves emitting from warm objects such as humans and animals, which translate infrared into visible colors. 

Far infrared waves are thermal. In other words, we experience this type of infrared radiation every day in the form of heat! The heat that we feel from sunlight, a fire, a radiator or a warm sidewalk is infrared. The temperature-sensitive nerve endings in our skin can detect the difference between inside body temperature and outside skin temperature.

Shorter, near infrared waves are not hot at all - in fact you cannot even feel them. These shorter wavelengths are the ones used by your TV's remote control. After knowing this, you will understand sales people who claim their heaters are full spectrum, are saying something completely meaningless.

Since the primary source of infrared radiation is heat or thermal radiation, any object which has a temperature radiates in the infrared. When an object is not quite hot enough to radiate visible light, it will emit most of its energy in the infrared. For example, hot charcoal may not give off light but it does emit infrared radiation which we feel as heat. The warmer the object, the more infrared radiation it emits.

Humans, at normal body temperature, radiate most strongly in the infrared at a wavelength of about 7-14 microns. (A micron is the term commonly used in astronomy for a micrometer or one millionth of a meter.) This image on left ( which is courtesy of the Infrared Processing and Analysis Center at CalTech), shows a man holding up a lighted match! Which parts of this image do you think have the warmest temperature? How does the temperature of this man's glasses compare to the temperature of his hand? To make infrared pictures like the one on the left, we can use special cameras and film that detect differences in temperature, and then assign different brightness or false colors to them. This provides a picture that our eyes can interpret. Many things besides people and animals emit infrared light - the Earth, the Sun, and far away things like stars and galaxies also do as well !

The image on right (courtesy of SE-IR Corporation) shows a cat in the infrared. The orange areas are the warmest and the white-blue areas are the coldest. This image gives us a different view of a familiar animal as well as information we could not get from a visible light picture. We know, from looking at an infrared image of a cat, that many things emit infrared.

The infrared heat produced by our infrared saunas is the same wavelength that is emit from our body.  Our bodies naturally radiate far infrared energy through the skin at between 7 to 14 microns in order to keep us warm. For any far infrared benefits, you can refer to studies done by many physicians or research fellows.

Strict quality control ensures our sauna's infrared heaters have achieved the highest standards for technical functionality and aesthetic workmanship. Our premium grade far infrared heaters produce radiant heat output in the 7 –14 micron wavelength range for maximum benefit. Unlike the sun’s radiation, the radiant heat from our heaters do not contain Ultraviolet or other harmful radiation. Our saunas uses about the same amount of power as a standard toaster to operate, and are therefore much more cost efficient than a traditional sauna. The infrared thermal system of our saunas helps to generate more sweat  than would be produced in a traditional sauna, leading to a much more rewarding experience.
