Far infrared rays (FIR) produce the same heat radiation as the sun. It is, in fact, exactly the same heat as the heat produced by our bodies as a result of exercising.
In the human body FIR reaches a depth of 5cm. For this reason FIR is usually called healing and vitalizing ”Deep heat”. FIR therapy is healthy, natural and safe. Infrared light allows uniform deep heat penetration that is highly effective as a source of healing.
- light from the sun. Over half of the sun’s energy is radiated in the wavelength area of FIR. FIR waves are the safest and the most beneficial of the sun’s waves.
- neither ultraviolet radiation nor atomic radiation.
- a form of energy that heats objects directly through a process called “conversion” without having to heat the air in between;
- also known as infrared energy-IR.
Heat can transform in three different ways:
Conduction – Transfer of energy between objects that are in physical contact
Radiation – Transfer of energy to or from the body by means of the emission or absorption of electromagnetic radiation. Thermal radiation is energy emitted by matter as electromagnetic waves
Convection – The transfer of energy from one location to another as a side effect of physically moving an object containing that energy
Science of it:
All material more than absolute zero (-273°C) radiate energy of Far infrared (FIR) region. The higher the temperature, the higher the radiation dose (energy) is. It is known that the amount of radiation in same temperature is affected by the material itself and the condition of its surface. Ceramic materials are known to radiate a lot of far infrared rays (FIR). The radiation of FIR is low in metal, however metal reflects it well. Therefore metals are used as a reflector with high reflectance.
In general, the heat moves from higher temperature to lower temperature. Heating by radiation warms the object more evenly, than with convection. The temperature on the objects’ surface is always much warmer than in the inside, when heating is done with conduction.
When the wavelength of the radiation is controlled, is the need for energy usually smaller, than the corresponding heating with heaters based on conduction. Furthermore – FIR penetrates deeper into receiving material.
Thermal radiation propagates without the presence of matter through the vacuum of space. Warming effect in the heaters that use FIR- technology is based specifically on the radiation – not on the conduction. In everyday life Thermal radiation can be sensed well in a sunny weather – in the sunlight it is warmer than in the shade, but the air has the same temperature in both cases.
The infrared segment of the electromagnetic spectrum is divided into three segments by wave length, measured in microns or micrometers (a micron = 1/1,000,000 meter);
076-1.5 microns = near or close;
1.5-5.6 = middle or intermediate;
5.6-1000 = far or long-wave infrared.
The infrared segment of the electromagnetic spectrum occurs just below or “infra” to red light as the next lowest energy band of light. This band of light is not visible to human eyes but can be seen by special cameras that translate infrared into colors visible to our eyes. However, we sense this type of light, perceived as heat.
The sun creates most of its energy within the infrared segment of the spectrum. Our atmosphere has a “window” that allows FIR in the 7-14 micron range to safely reach the earth’s surface. When warmed, the earth radiates infrared rays in the 7-14 micron band and has a peak output at 10 microns.
The infrared heat in a green house is just like the heat from the sun or that which our own bodies produce as they burn fuel to keep us warm. Supposedly, bodily tissues needing a boost in their output selectively absorb FIR rays. The internal production of infrared energy that normally occurs within our tissues is associated with a variety of healing processes. After boosting a tissue’s level to maximum, the remaining rays pass onward harmlessly. This phenomenon is called “resonant absorption.”
