There was a literature report: 1998 The World Health Organization listed five major effects of electromagnetic radiation on human body:
First, electromagnetic radiation is the main cause of cardiovascular disease, diabetes and cancer mutation;
Second, electromagnetic radiation does harm to human reproductive system, nervous system and immune system;
Thirdly, electromagnetic radiation is the inducing factor of pregnancy abortion, infertility, teratoma and other diseases;
Fourth, electromagnetic radiation directly affects children's development and bone development, leading to decreased vision, retinal detachment and decreased liver hematopoietic function;
5. Although electromagnetic radiation will reduce physiological function and make women's endocrine disorders and menstrual disorders, many media confuse "magnetic pollution" with the normal "magnetic effect". It should be recognized that these problems that are harmful to human body stem from excessive "pollution" of electromagnetic shielding materials. According to the data provided by many environmental protection materials, when the computer is running, the electromagnetic waves emitted by the chassis main body and the display will
Computer radiation
The research institute tested the electromagnetic field intensity of the computer. The results show that the electromagnetic field intensity near the screen is 0.9, while the electromagnetic field intensity about 5 cm away from the screen is less than 0. 1, which is almost impossible to measure at a distance of 30 cm (this is the customary distance between the computer operator's body and the screen).
Computer radiation avoidance method
1. Avoid operating the computer continuously for a long time and pay attention to rest. To maintain a most suitable posture, the distance between the eyes and the screen should be 40~50 cm, so that the eyes can look down or slightly down at the screen.
2. Maintain a good indoor working environment, such as comfortable temperature, clean air, proper negative ion concentration and ozone concentration.
3. The light in the computer room should be suitable, neither too bright nor too dark, so as to avoid the interference of light caused by direct irradiation on the fluorescent screen. The studio should be kept ventilated and dry. 4. Color filters should be used on the computer screen to reduce visual fatigue. It is best to use glass or high-quality plastic filters.
5. Install protective devices to reduce the intensity of electromagnetic radiation.
6. Pay attention to keep your skin clean. There is a lot of static electricity on the surface of computer screen, and the accumulated dust can be transferred to the exposed parts of face and hand skin for a long time, which is prone to macula and pigmentation, and even cause skin lesions in severe cases.
7. Pay attention to supplementary nutrition. Computer operators working in front of the screen for too long will consume rhodopsin on the retina, which is mainly synthesized by vitamin A. Therefore, computer operators should eat more foods such as carrots, Chinese cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal livers and lean meat to supplement vitamin A and protein in the human body. Drink more tea, tea polyphenols and other active substances in tea can help absorb and resist radioactive substances.
8. Try to buy a new computer and generally don't use an old one. The radiation of old computers is generally severe, which is generally 1-2 times that of new computers at the same distance and similar models.
9. Computer placement is very important. Try not to let the back of the screen face people, because the back of the computer has the strongest radiation, followed by the left and right sides, and the front of the screen has the weakest radiation.
10. Adjust the screen brightness when using the computer. Generally speaking, the brighter the screen, the stronger the electromagnetic radiation, and vice versa. But it can't be too dark, so as not to affect the effect because of low brightness, which is easy to cause eye fatigue.

Protection strategy
The first trick: For busy people, the easiest way to resist computer radiation is to drink 2-3 cups of green tea and eat an orange every morning. Tea is rich in provitamin A, which can be quickly converted into vitamin A after being absorbed by human body. Vitamin A can not only synthesize rhodopsin, but also make eyes see things more clearly in dark light. 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. Spirulina and sea buckthorn oil also have anti-radiation effects.
The second measure: do skin care isolation before surfing the internet. For example, the use of pearl membrane, the unique "South Pearl Cui Membrane" forms a layer of 0.00 1mm pearl membrane on the skin, which can effectively prevent environmental pollution and radiation; Secondly, after the computer is used, many particles of electromagnetic radiation will be adsorbed on the face. Wash your face with clear water in time, which will reduce radiation by more than 70%!
The third measure: when operating a computer, it is best to install a computer-specific color filter on the display screen to reduce the harm of radiation, and do not place miscellaneous metal objects indoors to avoid the re-emission of electromagnetic waves. When using a computer, you need to adjust the brightness of the screen. Generally speaking, the brighter the screen, the stronger the electromagnetic radiation, and vice versa. But it can't be too dark, so as not to affect the effect because of low brightness, which is easy to cause eye fatigue.
The fourth measure: you should try to buy a new computer, and generally don't use an old computer. The radiation of old computers is generally severe. In the case of the same distance and similar models, it is generally 1-2 times that of the new computer.
The fifth measure: the location of the computer is very important. Try not to let the back of the screen face people, because the back of the computer has the strongest radiation, followed by the left and right sides, and the front of the screen has the weakest radiation. As long as you can see clearly, the distance should be at least 50 cm to 75 cm, which can reduce the harm of electromagnetic radiation.
The sixth measure: pay attention to indoor ventilation: scientific research has confirmed that computer screens will produce a carcinogen called dibenzofuran bromide. Therefore, it is best to install a ventilator in the room where the computer is placed. If not, pay special attention to ventilation when surfing the internet.
Seventh measure: Pay attention to eat more foods rich in vitamins A, C and protein, such as carrots, bean sprouts, tomatoes, lean meat and animal livers, and often drink some green tea.
Eighth trick: People who often work in front of the computer often feel dry eyes and pain, so it is necessary to put some bananas on the computer desk. The potassium in banana can help the human body to discharge excess salt, make the body reach the balance of potassium and sodium, and relieve the discomfort of eyes. In addition, bananas contain a lot of beta carotene. When the human body lacks this substance, the eyes will become painful, dry, dull and dehydrated. Eating more bananas can not only relieve these symptoms, but also relieve eye fatigue to some extent and avoid premature eye aging.
The ninth trick: put a few pots of cactus next to the computer, which can effectively absorb radiation.
I hope I can help you ... Have a nice life!
