When it comes to infrared, there may be many people who are not unfamiliar with him, but when it comes to how much they know him, there may be many people who do not know enough about him, and today, I want to discuss with you about the problem of infrared is harmful to the human body, in addition, in explaining to you how to prevent infrared, help everyone live and work better, and make our bodies healthier.
Is infrared harmful to the human body? How to prevent infrared?
Is infrared harmful to the human body?
First, the essence of light is actually electromagnetic waves, including infrared, visible light and ultraviolet rays, but the frequency is much higher than the frequency of radio waves used in mobile communications. Infrared, visible light is harmless to the human body, ultraviolet radiation of the human body can also kill sterilization, but more light will be harmful to the human body, such as carcinogenic. Sunlight contains ultraviolet rays. Higher than the frequency of light are X-rays, Y-rays, cosmic rays, etc., among which, X-rays commonly used in hospital chest X-ray equipment are definitely harmful to the human body if they irradiate the human body for a long time. There have been examples of long-term exposure to X-rays causing cancer.
Second, the damage effect of infrared rays in sunlight on the skin is different from ultraviolet rays. Ultraviolet light mainly causes photochemical reactions and photoimmunological reactions, while the reactions produced by infrared irradiation are caused by molecular vibration and temperature rise. Thermal radiation caused by infrared rays penetrates the skin more than ultraviolet rays. 25%~65% of its radiation can reach the epidermis and dermis, and 8%~17% can reach the subcutaneous tissue. Infrared rays through its thermal radiation effect to increase the skin temperature, telangiectasia, hyperemia, increase epidermal water evaporation and other direct adverse effects on the skin. Its main manifestations are erythematous papules, premature skin aging, and pigmentary disorders. Skin temperature rises, telangiectasia hyperemia, increases epidermal water evaporation, etc. directly cause adverse effects on the skin.
How to prevent infrared?
1, the effective method is the same as the infrared feature of the background, so that the infrared detection method can not be used to separate the target, in technology, you can use masking, special coatings to make the infrared feature of the target as close to the background as possible. It is necessary to select the appropriate masking method or coating according to a special technical manual or sampling inspection.
2. Use a mirror to reflect infrared rays in other directions, and prevent infrared detection behind the mirror.
3. The use of high-tech anti-infrared fabric, has been used in the camouflage clothing of the US military.
Is infrared harmful to the human body and how to prevent infrared rays, after reading the introduction of the above editor, is everyone's heart more clearly understood. Xiaobian suggests that everyone must pay more attention to personal health in daily life, you can do more physical exercise, now many products are involved in infrared, so appropriate reception of infrared, for our human body will not have an impact.
