1800 A.D. German scientist "Herschel" found that the sun's infrared rays around the outside of the naked eye can not be seen around a source of light, wavelengths between 5.6-1000UM "far-infrared rays", after the irradiation of this light source, the organism will produce radiation, penetration, absorption, **** vibration of the effect. NASA (NASA) research report pointed out that, within the infrared, the human body has to help 4-14 micron far infrared, can penetrate the human body internal 15CM, from the internal heat, from the role of the body to promote the expansion of microvessels, so that the blood circulation smooth, to achieve the purpose of the metabolism, which increases the body's immunity and the rate of healing.
But according to the theory of blackbody radiation, the general material to produce sufficient intensity of far-infrared rays, and not easy, usually must be assisted by a special material for the conversion of energy, it will be absorbed by the heat through the vibration of internal molecules and then issued by the longer wavelengths of the far-infrared rays out.
★Far infrared rays in nature
Sunlight contains far infrared rays, but you can't enjoy far infrared rays alone when sunbathing, but there are some special substances in nature that can absorb the energy of the human body or the surrounding area and then convert it into far infrared rays to be radiated out. There are three categories:
1. Ceramic Powder
2. Long Carbon Powder
3. Tourmaline Powder
★Far Infrared Rays
1. Improve microcirculation
2. Enhance immune system function
3. Increase skin activity
4. Improve joint pain
5. Improve body oxygenation
6. Promote metabolism
★Practical use of far infrared rays
In recent years, far infrared rays have been widely used in the world in the adjuvant treatment of many diseases. In recent years, far-infrared rays have been widely used in many diseases around the world, mainly to promote blood circulation by using far-infrared rays, and to achieve the purpose of auxiliary treatment.
Listed as follows:
1. Medical: Aches and pains patch, ceramic health meter.
2. Industry: far-infrared oil saving gas pedal.
3. Textile: far-infrared fabrics.
4. beauty: far-infrared oven, far-infrared slimming cabin

The discovery of the solar infrared
Herschel had a doubt in his mind, usually the sunlight he observed, the different colors of the color light contains the same amount of heat?
1800, he designed a simple experiment, let the sunlight through the prism, resulting in a seven-color spectrum, the use of three black-coated alcohol ball thermometer (more able to absorb radiant heat), one placed in the visible light of a certain color light, the other two placed in the visible light outside the measurement of the background value, and found that from the violet, blue, green, yellow, orange light to red light, the temperature increases in order!
What's even more incredible is that he found that the temperature was actually higher in the area next to the red light area, where there was light invisible to the naked eye! This was the first time humans discovered light invisible to the naked eye, called 'infrared'.
However, it is important to add that the energy emitted by the sun is in fact the strongest green light with a wavelength of 5800 A. The reason why Hounshell measured longer wavelengths and higher temperatures is that, in his experiments, the process of refraction occurs when the energy of long-wavelength light is more concentrated, while the energy of short-wavelength light is more dispersed.
This year (2000) is the 200th anniversary of the discovery of infrared light; now, mankind has been able to use infrared detection to do a lot of things: astronomy, medical care, security, military, resource surveys, satellite cloud charts, sea temperature observations and so on.

Infrared is a famous foreign scientists Herschel in a scientific experiment found that he found in the sun's visible light outside the existence of a magical light, the human eye can not see this kind of light, but it is extremely similar to the physical properties and the visible light, with a distinctive heat radiation. Because it is located in the visible light outside the red light, so it is called infrared, infrared wavelength range is very wide, between 0.75 - 1,000 microns, in the infrared, shorter wavelengths for the near-infrared, and the far-infrared is the infrared wavelengths in the infrared of the longest section of infrared light. According to the different requirements of the user, the division of the standard is not the same, in the practical application, usually the wavelength of infrared in 2.5 microns or more is called far infrared.
Far infrared is a kind of electromagnetic wave; it is invisible light, but has all the characteristics of visible light, the main physical characteristics of far infrared are as follows:
1, emissive:
Because the far-infrared is the range of electromagnetic waves belonging to the light, so it is the same with the light does not require any medium can be directly transmitted, which is the far-infrared emissive.
2, permeability (penetration):
While far infrared is an electromagnetic wave belonging to the light, but the penetration is different from other visible light. Far infrared has a unique penetrating power, its energy can act to a certain depth of subcutaneous tissue, and then through the blood circulation, the energy to reach the deep tissues and organs. This is the permeability of far infrared rays.
3, absorption, **** vibration:
According to Kirchhoff's law of radiation: any good radiator is necessarily a good absorber. At the same temperature, the greater the capacity of the radiating body, the stronger its absorption capacity, the two are directly proportional to the relationship between all objects containing far-infrared, both can radiate far-infrared, but also can absorb far-infrared, radiation and absorption of the counterparts. And the human body every moment are also emitting far infrared rays, it is determined that: the human body emits far infrared wavelength of 9.6 microns, so the far infrared wavelength produced by the health of the Dragon brand series of products in 8----15 microns, and the human body's surface peaks are matched, the formation of the optimal absorption and can be converted into the internal energy of the human body, and very closely affects the origins of human life, the occurrence and development, so we are Therefore, we also call this wavelength range of far infrared rays as the light of life. Therefore, far infrared rays have good absorption, **** vibration.

Infrared ray is actually a kind of light, but also a kind of electromagnetic wave, just its wavelength than the visible red light is longer, we can see the human eye law, but the skin of the body can feel the warmth of its effect. The British astronomer Herschel discovered infrared light in 1800.
To understand far-infrared rays, we must first understand what infrared rays are. Infrared is actually a kind of light, also a kind of electromagnetic wave, just its wavelength is longer than the visible red light, our human eyes can see, but the skin of the body can feel its warm effect. Infrared in the electromagnetic spectrum (electromagnetic wave family), is between the visible red light and commonly known as microwave (or millimeter wave). Usually as long as the temperature of the object, will keep issuing infrared radiation, with the temperature of the high and low, the composition of the object is different, the wavelength of infrared radiation is not the same, the surface temperature of our human body is about 32 degrees Celsius, so the human body has been emitting the surface of the wavelength of more than a dozen micrometers (a micron = 10-6 meters) of infrared radiation, you only need to have a starlight night vision goggles can be seen in the infrared radiation emitted by human beings! The infrared light is a very powerful and effective way to reduce the risk of damage to your body.
