action principle
Infrared ray is one of the rays that can penetrate the skin and subcutaneous tissue most in all sunlight. Because the far infrared ray is close to the vibration frequency of cells and molecules in human body, the "life light wave" will cause the atoms and molecules of human cells to vibrate after penetrating into the body. Through the absorption of * * *, the friction between molecules will generate heat to form a thermal reaction, which will promote the temperature rise in the deep subcutaneous layer, dilate the microvessels, accelerate the blood circulation, help to remove the vascular deposits and harmful substances in the body, remove the obstacles that hinder metabolism, revive tissues, and promote the production of enzymes again. Therefore, far infrared rays can improve and prevent many diseases caused by blood circulation and microcirculation disorders.
In addition, some harmful substances in the human body, such as toxic substances such as heavy metals in food, lactic acid, free fatty acids, fat and subcutaneous fat, sodium ions, uric acid, cosmetic residues accumulated in capillaries, etc. It can be directly excreted from the skin and sweat through metabolism without going through the kidneys, which can avoid increasing the burden on the kidneys.
Generally speaking, the infrared rays emitted by the heat sources of fuel combustion and electric heating appliances are mostly near infrared rays. Because of their short wavelength, they produce a lot of thermal effects, which will cause skin burns and lens damage after long-term irradiation. Other electromagnetic waves with shorter wavelengths, such as ultraviolet rays, X-rays, and gamma rays, will dissociate electrons on atoms, which is more harmful to human body. On the other hand, the far infrared ray has a long wavelength and relatively low energy, so the danger of burning is relatively small when it is used.
Far infrared rays are also different from low-frequency electromagnetic waves emitted by household appliances. Low-frequency electromagnetic waves emitted by household appliances can penetrate walls and change the characteristics of human current, so people highly doubt its harmfulness. The penetrating power of far infrared rays in human skin is only 0.0 1 to 0. 1 cm, and the human body itself emits far infrared rays with a wavelength of about 9 microns, which cannot be confused with low-frequency electromagnetic waves. Far-infrared rays are used in the adjuvant treatment of many diseases, such as muscle soreness, tendinitis, bedsore, burns and wounds that are difficult to heal. It can be used to promote blood circulation and achieve the purpose of adjuvant therapy.
The benefits of far infrared rays to human body
(1) activates water molecules and increases oxygen content in the body.
The human body is about 70% water. The water content of blood is as high as 80%. If insufficient blood gas occurs, water molecules in the blood will assemble into inert water (that is, four hydrogen molecules combine with one oxygen molecule) and cannot pass through the cell membrane. Far infrared rays can make water molecules vibrate and become independent water molecules (that is, two hydrogens combine with one oxygen molecule), which increases the oxygen content of the body, restores the vitality of cells, makes the spirit more vigorous, and makes the mind more flexible, thus improving the disease resistance and delaying aging.
(2) improve the microcirculation system
Independent water molecules can move freely inside and outside the cell, and then they are converted into heat energy by * * * * vibration, which makes the deep subcutaneous temperature slightly rise, the blood flow speed accelerate, and the microfilament blood vessels dilate; The more microfilament blood vessels are opened, the pressure on the heart can be reduced. The function of microfilament blood vessels is to supply oxygen and nutrition to 60 trillion cells of human body, and at the same time excrete waste produced by metabolism. If there is something wrong with the microcirculation system, it will lead to many problems, including hypertension, cardiovascular diseases, tumors, arthritis, cold paralysis of limbs and so on. The total length of adult microfilament blood vessels can circle the earth three times, and it is called the second heart of human body, which shows its importance.
③ Promote metabolism.
If the microcirculation system is improved, the waste produced by metabolism can be quickly excreted, reducing the burden on the liver and kidneys. These wastes include carcinogenic heavy metals: lactic acid, free fatty acids and subcutaneous fat that cause fatigue and aging; Uranium ions that cause hypertension and uric acid that causes pain.
(4) Balance the pH of the body
Far-infrared rays can purify blood, improve skin quality and prevent joint pain caused by uric acid is too high.
Far infrared products include underwear, waist protectors, knee protectors, mattresses, pillows and quilts. Its main function is to promote blood circulation in different parts of the body, prevent soreness and discomfort, eliminate fatigue, and prevent diseases such as rheumatoid arthritis, hyperosteogeny, scapulohumeral periarthritis, cervicitis, lumbago, and paralysis of hands and feet.
It is forbidden for those with bleeding tendency: far infrared rays should be used with caution in the treatment of suspected malignant tumors; People with cardiovascular insufficiency wear thermal underwear with far infrared rays, which may also cause arrhythmia or angina pectoris: new scars should also avoid contact with far infrared rays, otherwise it will promote their proliferation.
