Far infrared rays
1, improve joint pain: far infrared rays penetrate deep into the muscle joints, so that the body's internal warmth, relaxation of the muscles, driven by the microvascular network of the exchange of oxygen and nutrients, and exclude the body's fatigue accumulated in the body of substances and lactic acid and other aging wastes on the elimination of swelling, and alleviate the effect of the aches and pains of the excellent.
2, ? Regulation of autonomic nervous system: autonomic nervous system is mainly to regulate the function of internal organs, people in a state of anxiety for a long time, the autonomic nervous system continues to be tense, will lead to reduced immunity, headache, dizziness, insomnia, fatigue, cold limbs. Far infrared rays can regulate the autonomic nervous system to maintain the best state, the above symptoms can be improved or eliminated.
What is the harm of infrared radiation on the human body
1, ? Infrared radiation on the body's impact is mainly skin and eyes. Infrared irradiation of the skin, most of which can be absorbed, only about 1.4% is reflected. Large intensity of short-term irradiation, skin local temperature increases, vasodilatation, erythema reaction, stop irradiation erythema disappeared. After repeated irradiation, local pigmentation may appear. After excessive irradiation, especially near-infrared (short-wave infrared), in addition to acute burns of the skin, can also penetrate into the subcutaneous tissue, heating blood and deep tissue.
2, long-term exposure to low-energy infrared, can lead to chronic eye damage, common for chronic congestive blepharitis. Short-wave infrared light can be absorbed by the cornea to produce thermal damage to the cornea, and can pass through the cornea to injure the iris, and cataracts are often seen in workers with long working hours.
Sunlight can be roughly divided into visible and invisible light. Visible light is refracted through a prism to produce rays of violet, blue, cyan, green, yellow, orange and red colors (spectrum). The light outside of the red light, in a section of the spectrum with wavelengths ranging from 0.75 to 1,000 micrometers, is called infrared light, or IR. Infrared light belongs to the category of electromagnetic waves, a kind of electromagnetic wave with strong thermal effect.
Infrared wavelength range is very wide, people will be different wavelength range of infrared light is divided into near-infrared, mid-infrared and far-infrared region, the corresponding wavelength of the electromagnetic wave is called near-infrared, mid-infrared and far-infrared. Infrared is a kind of light wave, its wavelength is shorter than radio waves and longer than visible light. Infrared light is invisible to the naked eye, and any object emits infrared light. Infrared radiation from hot objects is stronger than from cold objects.
