Long-wave or far infrared rays are part of the spectrum of solar rays and are invisible to the human eye. Long-wave infrared radiation has waves with a length of 4 to 400 microns, among which 90 % of the waves are 8-14 microns long.
The infrared spectrum with the region of wavelengths of about 8 to 14 microns has a truly unique beneficial effect on the human body. This part of the infrared radiation corresponds to the radiation of the human body itself with a maximum wavelength of about 10 microns.
Several decades ago scientists in the field of aerospace conducted research on the conditions of human existence in space under zero gravity, vacuum, extreme loads and low temperatures. It was then discovered that a necessary condition for the normal functioning of the human body is to receive waves of solar radiation with a length of 8-14 microns (IR rays). Therefore, long-wave infrared rays are called "life-giving sun rays". These rays help the body to maintain temperature and acid-base balance.
By affecting the human body in the long-wave part of the infrared range, a phenomenon called "resonant absorption" can occur, in which case external energy will be actively absorbed by the body. As a result of this effect, the potential energy of the body cell increases, and unbound water leaves it (lymph outflow increases), the activity of specific cell structures increases, the level of immunoglobulins increases, the activity of enzymes and estrogens increases, and other biochemical reactions take place. This applies to all types of body cells and blood.
Due to reflex reactions, IR rays have a resorbing, anti-inflammatory, anti-spasmodic and analgesic effect. IR rays, when exposed to the human body, accelerate the movement of electrons in orbits and cause a thermal effect. The heat of IR rays penetrates deep into the tissues. Under their influence, tissue metabolism increases, the ability of white blood cells to absorb pathogenic microbes increases, calming and analgesic effects are manifested, which helps to stop inflammatory processes.
Famous ancient doctors Hippocrates, Celsus, and Antillus actively used sun baths in the treatment of diseases of the skin, nervous system, rickets, and arthritis. Hippocrates described a method of using infrared rays for the treatment of wounds, ulcers, damage from cold etc.
The human body emits far infrared rays from 3 to 50 micrometers long, most of which correspond to a wavelength approximately equal to 10 microns. Our body, radiating long infrared waves itself, needs constant feeding with long-wave heat. If there is no such recharge taking place, the body quickly weakens, ages, and develops various diseases against the background of deterioration in general health.
Since the constant absorption of infrared rays contributes to the surge of strength and health of our body, people intuitively look for its sources. Special emitters are created for everyday use at work and at home. Their rays pass through the air, almost without heating it, penetrate not only under the human skin, but also deep into the tissues, triggering vital reactions inside the cells. This phenomenon is called "resonant absorption" and applies to all types of cells in the body, including blood.
Far infrared radiation has two types of positive effects on the human body.
The first is associated with a general strengthening effect and is based on strengthening the body's natural resistance to diseases, i.e. increasing immunity.
The second is a direct therapeutic effect for various health problems that can be eliminated with regular use, such as
Heart and vascular diseases
Back pain, etc.
