What preventive measures should be taken in view of the harm to computer work for a long time every day?

1. You should 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.

2. 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.

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.

4. Don't put metal objects indoors to avoid electromagnetic waves from being emitted again.

When operating a computer, it is best to install a computer-specific color filter on the display screen to reduce the harm of radiation.

6. Adjust the brightness of the screen 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.

7. When using the computer, keep a proper distance from the screen. The closer you are to the screen, the greater the electromagnetic radiation the human body receives, so it is best to stay half a meter away from the screen.

8. After using the computer, many particles of electromagnetic radiation will be adsorbed on the face. Therefore, washing your face with clean water in time will reduce radiation exposure by more than 70%.

9. You can put a cactus in front of the computer desk to help reduce radiation.

10. Pay attention to your diet. 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.

The first trick: when using the computer, 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 to avoid eye fatigue.

The second measure: try to avoid the face being too close to the monitor, and keep an appropriate distance from the screen, at least 0.5 meters away from the screen.

The third trick: the location of the computer is also very important. Try not to let the back of the screen face people, because the radiation on the left and right sides and the back of the computer monitor is much stronger than that on the front of the screen.

The fourth measure: when copying documents, if the copy volume is large, set up the program and put it aside.

The fifth measure: don't put household appliances too concentrated.

The sixth measure: to protect computer radiation, in addition to improving the working environment and paying attention to the use method, you can also take measures such as providing radiation protection clothing, radiation protection screens and radiation protection glasses for computer operators (especially pregnant women) to reduce injuries.

Create a healthy menu to reduce radiation damage.

At 9 o'clock in the morning, Amanda, who works in a bank, turned on her computer to get ready for work. At five o'clock in the afternoon, Amanda is waiting at her desk to confirm that the computer is turned off. Are you like her every day? The answer is mostly yes.

As we all know, your close contact with the computer for a whole day has not only brought you neck pain and shoulder pain, but also quietly buried hidden dangers for your health.

It's not just computer radiation. The progress of science and technology makes household appliances an indispensable helper in our lives. But have we ever paid attention to the harm of electromagnetic radiation it emits to human body? Some experts believe that electromagnetic radiation comes from computers, televisions, mobile phones, microwave ovens, induction cookers, electric blankets, refrigerators and air conditioners. Because of its short wave length, high frequency, high energy and strong biological effect, it will cause different degrees of harm to human nerves, endocrine, cardiovascular system, blood, immunity and vision, such as headache, insomnia, arrhythmia and decreased vision.

At present, electromagnetic radiation has become a new pollution source after air pollution, water pollution and noise pollution.

Create a healthy menu to reduce radiation damage.

Scientific research shows that the harm of electromagnetic radiation to human body is related to its peroxidation, so to prevent electromagnetic radiation, in addition to avoiding "close contact" with electromagnetic waves, eating food with antioxidant effect can also reduce the harm of electromagnetic radiation to human body.

"First of all, we should pay attention to the intake of trace element selenium," Ji Changhai, deputy director of the physical examination department of the new group of health professionals, told reporters. "Selenium has antioxidant effect. Antioxidants can reduce the harm of radiation to human body, because they can remove free radicals that lead to human peroxidation. Selenium-enriched foods are mainly sesame, malt and Chinese herbal medicine Astragalus, followed by yeast, eggs, beer and seafood. "

Pay attention to the balanced supplement of vitamins can also fight against free radicals. In this regard, Dr. Ji Changhai also told reporters: "Vitamins A, C and E are good antioxidant combinations. Vitamin C is a water-soluble vitamin, which is rich in various fruits and vegetables, so eating more fruits and vegetables can enhance the resistance to electromagnetic radiation, while vitamins A and E are fat-soluble. Foods rich in vitamins A and E are recommended to be fried, which is beneficial to their dissolution in oil and easy for human body to ingest and absorb. Cruciferous vegetables such as beans, rape, mustard, cabbage, radish and animal offal are rich in vitamin E, which is very effective in helping to protect cell membranes from free radical attacks. "

Miss Xia, a financial supervisor in a foreign company, often feels sour eyes after working in front of the computer for a day. Eye drops have become her routine choice to relieve visual fatigue. "Computer people can't rely too much on eye drops to relieve visual fatigue. Frequent use will destroy your own function. First, they should spend less time using computers. Secondly, I suggest that they eat more foods that are good for their eyes, such as fish, carrots, spinach, sweet potatoes, medlar, sesame seeds, animal liver and so on. " Dr. Ji Changhai suggested.

In addition, for urbanites who often use computers, pepper and green tea should also be two essential items in the menu. Eating pepper can not only mobilize the whole immune system, but also protect the DNA of cells from radiation damage. Tea polyphenols, the most essential and effective component in tea, has anti-radiation effect and can reduce the adverse effects of various radiation on human body.

Get out of the misunderstanding of radiation protection

At present, many businesses are making a big fuss about the topic of "radiation protection", and constantly promoting technology-leading radiation protection products to consumers, such as glasses, gloves, masks and even maternity suits. Cosmetics merchants have not missed this opportunity, and various "radiation-proof cosmetics" have also appeared in black and pink. In this regard, some experts believe that the key to "radiation protection" is not to rely entirely on these "radiation protection" commodities, but to reduce the contact time with radiation sources and reduce the radiation intensity of electronic products.

It is understood that at present, China has strict regulations on the radiation of electronic products, such as compulsory 3C certification. But from the actual situation, it is unrealistic to completely eliminate radiation in computer design. Therefore, as a user, you can buy a display that has been certified by TCO (TCO series electromagnetic radiation restriction environmental protection specification), and choose the chassis of a big brand manufacturer or some special professional radiation protection products to avoid electromagnetic radiation problems.

In addition, Dr. Ji Changhai told reporters: "There is dust on TV sets and computers, and it is generally considered that this is just a health problem. However, the fact is not so simple. Dust is an important carrier of electromagnetic radiation. Even after the power is turned off, electromagnetic radiation remains in the dust. With the diffusion of dust in indoor air, it is easy to be absorbed by human skin and even enter the body with the respiratory tract. Over time, it will have a negative impact on health. So pay attention to wiping the TV and computer in time. "

Regarding the skin problems that may be caused by computer radiation, Miss Xiao, a beauty consultant, told female friends who often use computers, "Isolation cream may not be able to isolate computer radiation, because most of computer radiation belongs to low-frequency radiation, which is different from ultraviolet rays with a wavelength of 0.0 1~0.40 micron targeted by isolation cream and sunscreen. But the electrostatic effect of computer screen will absorb a lot of dust in the air. In the process of using the computer, the skin is in a dirty environment. Applying cream when using a computer can reduce the harm of dust to the skin. And wash your face with water in time after using the computer, which will reduce radiation exposure by more than half. "
