Infrared ray was discovered by British astronomer William Herschel in an experiment in 1800, and was also confirmed by German scientist Hudson in the same year. It is found in the experiment that there is a magical light besides red light in the solar spectrum. Human flesh can't be seen, but it can feel obvious thermal radiation. Scientists called this radiation infrared radiation, and later people used to call it infrared or infrared light.
From 1950s to 1970s, the National Aeronautics and Space Administration (NASA) of the United States conducted a study on "the living conditions of human beings in spacecraft". This paper mainly studies the necessary conditions for human survival in spacecraft under vacuum, weightlessness and ultra-low temperature conditions. This study confirmed that the far infrared ray with the wavelength of 6- 14 micron in sunlight is an indispensable and important factor for biological survival.
Second, the principle of far infrared ray
Infrared ray is an electromagnetic wave, accounting for 80% of solar radiation energy. So far, electromagnetic waves collectively referred to as infrared rays are divided into near infrared rays, middle infrared rays and far infrared rays. The sun emits electromagnetic waves of various wavelengths, including gamma rays, but only the electromagnetic waves with the wavelength of 4- 1000 micron are far infrared. If converted by temperature, it is equivalent to 450℃ to -270℃, that is, the electromagnetic wave emitted by the radiator at a lower temperature is far infrared.
Third, the core of far infrared ray.
The core of far infrared ray lies in its wavelength (4- 1000 micron) and the wavelength emitted by human body (the average body temperature is
36.5℃, converted to a wavelength of about 9.36 microns), the frequency band is in the same range, and the cell molecules in the human body can be activated accordingly. This phenomenon is called * * * vibration. It can activate cells, promote blood circulation, accelerate metabolism and improve human immunity.
Fourthly, the characteristics of far infrared ray.
A) Far infrared ray is an invisible ray, which is an electromagnetic wave with long wavelength in the sun.
B) Far infrared ray has the linearity, attenuation, reflectivity and penetrability of light. It has strong radiation ability and can directly heat objects without raising the temperature of gases or other objects in the air.
C) Far infrared rays can be absorbed by various objects with the same wavelength, resulting in * * * vibration effect and warmth effect.
D) Far infrared rays have a strong permeability, which can penetrate to the skin of human body about 4-5 cm, and make cells and tissues generate a lot of heat through vibration effect.
E) The frequency of 6- 14 micron band in far infrared ray is the same as the vibration frequency of water molecules in biological cells, and it is easy to be absorbed, thus radiating heat energy from the inside out and activating cell tissues. This band of far infrared rays has high temperature effect and is ideal for human body.
Application of verb (abbreviation of verb) far infrared ray
Far infrared rays are widely used in heating, drying, health care, beauty, medical treatment, health care and so on. In the application of health care, the human body is 70% water, and excess fat and heavy metals are mixed in the water molecules in the body. The strong vibration of activated water molecules can cut off and separate fat and heavy metal substances, so that heavy metal substances and fat harmful to human body are released and excreted. Because in other words, far infrared rays can not only give cells activity, but also eliminate toxins and garbage in the body.
If it is only used for heating, the effect of near infrared ray and microwave is good, but the disadvantage of microwave and near infrared ray is that it will burn people or objects and destroy the structure of objects. For example, seaweed dried at high temperature will turn black and its fragrance will disappear, because chlorophyll will be destroyed by heating. If dried by far infrared rays, seaweed will become greener and more fragrant, because far infrared rays will not destroy chlorophyll and other components.
6. Far infrared ray is the light of life.
The human body emits far infrared rays all the time, and at the same time absorbs them all the time. Human life is inseparable from far infrared rays from its origin to its development. People usually think that exposure to strong sunlight for a long time will burn the skin or heatstroke; But that's caused by ultraviolet rays and near infrared rays in the sun's rays.
Far infrared rays have no side effects on human body. So far, scientists and medical workers have not reported the side effects of far infrared rays. It is a clean and safe energy for life and environment. For human beings, far infrared rays are indispensable from the origin of life to the end of life. It dominates the growth of all things on earth. People often say that everything grows on the sun, which is what we call far infrared rays. Therefore, people usually call it "the light of life".
Principle of far infrared heating.
As soon as the far infrared ray irradiates electromagnetic water molecules, it will produce rotary motion (vibration), thus giving the water molecules electric motion energy, accelerating the vibration of the molecules that are already moving and colliding with other molecules, which can generate a lot of heat. Far infrared ray itself is not heat, but light energy; It generates heat energy by colliding molecules with radiation.
Eight, the health function of far infrared rays
Everything grows on the sun, and human survival is inseparable from the sun, especially the far-infrared radiation in the sun, which is indispensable for human survival every day. Although we can't see it with the naked eye, we owe it every day. Life science has proved that human body is a far-infrared radiation source, the emitted far-infrared wavelength is about 6- 14 micron, and the optimal absorption band is 6- 14 micron. The cells that make up human organism are mainly composed of water molecules and polymer compounds, and water molecules in blood account for 60%-70%. Far infrared
It is easily absorbed by water molecules. Therefore, when far infrared rays irradiate the human body, they will be absorbed, permeated and reflected with the human body. This process is called "biological vibration" by scientists. That is to say, when the frequency band of 6- 14 micron far infrared ray is basically the same as the movement frequency of cell body molecules and water molecules between atoms in the body, the energy is absorbed by the body, which raises the deep temperature of subcutaneous tissue, and the generated warming effect activates the cell molecules, making them in a high-energy state, accelerating the synthesis of biological enzymes needed by the human body, and activating biological macromolecules such as protein at the same time, thus enhancing the immune function of the body. Repair damaged cells, enhance the regeneration ability of human biological cells and tissues, promote microcirculation in the body, accelerate the supply of nutritional ribozyme, promote health, and release harmful substances and fat out of the body. Far infrared rays can not only give vitality to the body, but also eliminate toxins and garbage in the body.
In fact, far infrared rays act on the human body, which is a natural therapy; For modern human diseases, far infrared rays are a panacea for sunlight; It achieves the purpose of disease resistance and physical therapy by activating the human body's own functions.
9. The difference between far infrared ray and near infrared ray, middle and far infrared ray and other rays: the wavelength of near infrared ray is about 0.75- 1.5 micron; The wavelength of mid-infrared is about: 1.5-4 microns; The wavelength of far infrared ray is about 4- 1000 micron;
From this point of view, it is difficult for near-middle infrared rays to radiate to the earth's surface through the atmosphere, and its radiation energy is too strong, which can destroy the molecular structure like ultraviolet rays and microwaves and is harmful to human body. For example, Europeans are prone to skin cancer; Japanese people are prone to cataracts. It can be seen that it is very important to protect the atmosphere and prevent ultraviolet radiation. Only far infrared rays are beneficial and indispensable radiation energy for human body.
There are many kinds of health care products with far infrared rays as working energy in the market: far infrared series bedding, far infrared underwear, various far infrared medical physiotherapy instruments and so on. , it's dizzying. Because scientific experiments show that far infrared ray is the only radiation in the sun that is harmless to human body and plays a vital role in human health. As we all know, the human body is not only an absorber of far infrared rays, but also an emitter of far infrared rays. Under normal circumstances, the human body is most closely related to far infrared rays with the wavelength of 6- 14 micron. In this frequency range, the far infrared rays continuously emitted by human body can also directly absorb the far infrared energy in this band, and at the same time directly supplement the biological energy of human tissues and organs.
Far-infrared energy is widely used in the fields of medical treatment and rehabilitation because of its characteristics from high to low, that is, energy can be transferred from a strong side to a weak side, which is very important for regulating the energy balance of various organs of the human body.
Far infrared rays have a strong penetrating ability, often reaching about 4-5 cm deep in the skin, and can transfer energy with the inside of the human body and human tissues and organs. Because the far infrared wavelengths emitted by them are in the same field, they can cause vibration and greatly activate human cells, which has a magical effect on promoting human metabolism and strengthening human microcirculation, and can also promote the discharge of waste in the body and enhance the energy of human tissues and organs, and has a strong detoxification and fitness function.
X. safety of far infrared energy
According to the research statistics of Dr. Tsu-Tsair Oliver Chi, by adjusting the far infrared device, far infrared rays suitable for human body frequency band can be emitted and acted on human body. These rays are selectively absorbed by human tissues according to needs, and the vitality of human tissues is improved. Far infrared rays can play a wide range of medical functions in body tissues, so that the therapeutic effect can reach the highest level, thus accelerating the rehabilitation process without causing any harm. This phenomenon is called "* * * vibration absorption".
The far-infrared light energy emitted by the far-infrared heating system is the same as the energy released by the sun, and it is also the same as the heat energy emitted by the "fuel" in our body to keep our body temperature. Our bodies penetrate the skin all the time, radiating infrared rays with the wavelength of 3-50 microns, mainly with the wavelength of 6- 14 microns. Qigong therapy has a history of 3000 years in China, which is developed according to the medical characteristics of far infrared rays in nature. Yoga in India also uses this principle and is recommended to treat eye fatigue. The far-infrared physiotherapy instrument has been widely used as the neonatal heating and physiotherapy equipment in hospitals for its heating performance and warm-keeping effect.
Cross current, written by Robert o Becker, MD, details the dangers of exposure to certain electromagnetic fields, such as working under high-voltage lines or in front of computer screens. For this kind of electromagnetic radiation that has radiation effect on human body, Japanese researchers use far infrared rays as an antidote.
