With the rapid development of technology, a variety of technological products, household appliances into people’s lives, computers, TVs, microwave ovens, induction cookers, stereos …… all this has greatly improved the efficiency of people’s work, improve people’s lives. However, with more and more electrical equipment at home, people feel convenient at the same time, but also brought the inescapable electromagnetic radiation. Electromagnetic radiation pollution has now become the fourth largest environmental pollution after water, air and noise. So, what is electromagnetic radiation? From a professional point of view, electromagnetic radiation is the phenomenon of energy in the form of electromagnetic waves transmitted through space. Almost any electrical appliance in our home will produce electromagnetic radiation. Today on the highest frequency of use, the average use of the longest appliances – computer generated electromagnetic radiation to talk about the author’s point of view. According to Jones? Hopkins University Medical Center scientists have shown that even the most insignificant electromagnetic radiation can cause nervousness, headaches, depression and insomnia and other symptoms, greatly increasing the incidence of various diseases. Experts at the University of Tokyo also found that, in addition to electromagnetic field radiation, computers also volatilize harmful substances into the air when they work, and these substances may also induce allergic reactions and respiratory diseases. The damage to the skin caused by computer radiation is a variety of “problem skin”, the more common manifestations are: 1, dry skin with fine lines; 2, yellowing; 3, a variety of patches, spots; 4, fine lines under the eyes, dark circles serious; 5, large pores, skin sensitivity; 6, long-term radiation will also cause skin loosening. Poor elasticity, the formation of bags under the eyes, etc.. The reasoning is not much to say, we can well understand. Long-term work in front of the computer, face-to-face acceptance of radiation, the human body is exposed to a certain dose of ionizing radiation, can produce a variety of biological effects harmful to health. These biological effects can cause abnormalities in skin metabolism and produce atrophy of the epidermis, when the skin becomes thin and smooth, hard and loses elasticity, damage to the stratum corneum and reduced resistance to various external damages. The sweat glands, sebaceous glands and hair follicles usually also atrophy, leading to dry skin and hair loss. Abnormal pigment metabolism is accompanied by increased hyperpigmentation and dilated capillaries. Prolonged use of the eyes can lead to excessive eye strain, and the subsequent problems of eye skin are dark circles, increased fine lines under the eyes, and bags under the eyes. So, how to solve the computer-based skin? In order to better prevent and reduce the skin problems caused by computer radiation, a lot of work can still be done. First of all, it is necessary to use the computer in a reasonable and scientific way. Should buy new computers as far as possible, generally do not use the old computer, the old computer radiation is generally more powerful, in the same distance, similar models of conditions, generally 1-2 times the new computer. Computer placement is very important, try not to let the back of the screen toward someone’s place, because the strongest computer radiation is the back, followed by the left and right sides, the front of the screen but the weakest radiation. When operating a computer, it is best to put a special computer color filter on the display to reduce the harm of radiation, do not place idle metal objects indoors to avoid the formation of electromagnetic waves re-emission. When using a computer, to adjust the screen brightness, in general, the greater the screen brightness, the stronger the electromagnetic radiation, and vice versa, the smaller. However, it can not be adjusted too dark, so as not to affect the effect of too little brightness, and easy to cause eye fatigue. Also pay attention to maintain an appropriate distance from the screen. The closer to the screen, the greater the electromagnetic radiation suffered by the human body, so it is better to be half a meter away from the screen. To be able to see the word clearly, at least 50 cm to 75 cm distance, which can reduce the damage of electromagnetic radiation. Also pay attention to indoor ventilation: scientific research has confirmed that the computer screen can produce a carcinogenic material called brominated dibenzofuran. Therefore, it is best to install a ventilation fan in the room where the computer is placed, and if not, pay particular attention to ventilation when using the computer. In addition, after the use of computers, the face will absorb a lot of electromagnetic radiation particles, to wash your face with water in time, so that the radiation will be reduced by more than 70%. Second, do a good job of facial protection, strengthen the whole body nutrition. 1, facial protection. Screen radiation generates static electricity, the most easily adsorbed dust, long time face to face, more likely to lead to spots and wrinkles. Therefore, before using the computer may wish to apply skin care lotion after adding a layer of light powder to slightly increase skin resistance. 2, thorough skin cleansing. After the end of computer use, the first task is to cleanse the skin, with warm water plus cleansing solution to thoroughly clean the face pang, the electrostatic adsorption of dust and dirt through the wash off, coated with mild skin care products. A long time can reduce the damage, moisturize the skin and skin. This is really a small move for women on the Internet can be described as a big effect. 3, maintenance of bright eyes. If you do not want to see people the next day when the eyes are red and swollen, dark circles plus a haggard face, do not fight for a long time continuously, especially do not stay up late online. Usually prepare a bottle of eye drops in case you need them. Computer use after a compress of cucumber slices, potato slices or frozen milk, herbal tea is also good. The method: cucumber or potato slices, put on the eyelids, close your eyes for a few minutes; or frozen milk, herbal tea with gauze moistened compress eyes, can relieve eye fatigue, nutrition around the eye skin. 4, increase nutrition. For people who often use computers, it is important to increase nutrition. Vitamin B complex is beneficial to brain workers, if you sleep late, the quality of sleep is also bad, should eat more animal liver, fresh fruits and vegetables, they are rich in vitamin B; meat, fish, dairy products to increase memory; chocolate, wheat doughnut, seafood, dried fruit can enhance the coordination of the nervous system, is the best small snacks when surfing the Internet. In addition, from time to time, drink some wolfberry juice and carrot juice, on the eye, skin care effectiveness is remarkable. If you care about your appearance, drink less carbonated drinks and drink carrot juice or other fresh juices instead. For people who live a stressful and busy life, the easiest way to resist computer radiation is to drink 2 to 3 cups of green tea and eat an orange every morning. Tea is rich in vitamin A original, it is absorbed by the body, can be quickly converted into vitamin A. Vitamin A can not only synthesize retinol, but also make the eyes in the dark light to see things more clearly, therefore, green tea can not only eliminate the harm of computer radiation, but also protect and improve vision. If you are not used to drinking green tea, chrysanthemum tea can also play a role in resisting computer radiation and regulating body functions. In addition, in the diet should also pay attention to the following aspects: ① eat more food beneficial to the eyes, such as eggs, fish, cod liver oil, carrots, spinach, groundnuts, pumpkins, wolfberries, chrysanthemums, sesame, radish, animal liver, etc.. ② Eat more foods with high calcium content, such as soy products, bone broth, eggs, milk, lean meat, shrimp, etc. ③Pay attention to vitamin supplementation: eat more fresh fruits and vegetables containing vitamins, etc. ④Pay attention to strengthening resistance: eat more foods that enhance the body’s ability to resist diseases, such as shiitake mushrooms, honey, fungus, kelp, mandarin oranges, dates, etc. ⑤ Eat some anti-radiation food: green vegetables, kelp, pig’s blood, mung beans, black fungus, etc. are all good choices in this regard. Drinking tea can reduce the harm of radiation, and the lipopolysaccharide in tea has an anti-radiation effect. Spirulina, sea buckthorn oil also has the effect of anti-radiation. 5, often do gymnastics. Long time use of computers, you may feel dizziness, stiff fingers, back pain, and even lower limb edema, varicose veins. Therefore, usually do gymnastics to maintain vigorous energy, such as lying flat in bed before going to bed, the whole body relaxed, the head back on the edge of the bed below, to relieve the brain after the lack of blood and oxygen supply; pad high feet, lying flat on the bed or sofa, to reduce the edema of the feet, and help blood flow back to prevent varicose veins in the lower limbs; in the process of computer use from time to time to stretch, stretching muscles or lean back on the chair, hands force to Back, to stretch the tension and fatigue of the lumbar muscles; do shaking finger exercise, which is the easiest way to completely relax the fingers. Remember, this kind of gymnastic exercise is not much, but far more effective than sleeping a lazy day. In addition, usually should also pay attention to exercise to enhance resistance. Computers and other household appliances brought about by electromagnetic ionizing radiation, although not completely removed and isolated, but there is no need to “like the enemy”, as long as scientific and reasonable to use, do the necessary protection, especially good skin care and maintenance, all problems can be prevented and controlled, you can enjoy them in the convenience brought about by You can enjoy the convenience they bring at the same time always stay young and beautiful.
