1. How big is the computer radiation
1. Keyboard 1000V/m
2. Mouse 450V/m
3 , Screen 218V/m
4. Host 170V/m.
The keyboard is a “junkyard”. In the course of daily work, many people may not realize that the keyboard that is used frequently may cause illness. First, the keyboard is a “junkyard” with dust, hair, fine hair, eyelashes, and more. According to statistics, this kind of dirt accumulates at an average rate of 2 grams per month. In addition, the keyboard surface is also covered with a large number of bacteria, such as Streptococcus, Staphylococcus aureus, Aspergillus fumigatus and so on.
I remind: The strongest radiation of the computer is the back. The second is the left and right sides, and the front of the screen has the weakest radiation. So try not to let the back of the screen face where there are people. The distance is based on the ability to read the characters clearly, at least 50 cm to 75 cm. Hazards
1. Excessive exposure to radiation may cause vision loss, cataracts and so on.
2. Computer radiation will affect men’s low sperm quality, women’s menstrual disorders, and may also cause fetal malformations or spontaneous abortions in pregnant women, seriously affecting the reproductive system of both men and women.
3. It will cause insomnia, palpitation, or leukopenia, decreased immune function and other cardiovascular manifestations.
4. When the computer radiation is serious, it will induce some cancers, and it will cause the cancer cells to multiply faster and affect our circulatory system.
Third, how to prevent computer radiation
1. Avoid operating the computer continuously for a long time , pay attention to the rest in between. To maintain a most appropriate posture, the distance between the eyes and the screen should be 40 to 50 cm, so that the eyes are looking flat or slightly down on the screen.
2. Maintain a good working environment indoors, such as comfortable temperature, clean air, appropriate anion concentration and ozone concentration.
3. The light in the computer room should be suitable, not too bright or too dark, to avoid the light directly shining on the fluorescent screen and causing interference light. The studio should be kept ventilated and dry.
4. Use a color filter on the computer screen to reduce visual fatigue. Glass or high-quality plastic filters are best.
5. Install protective devices to weaken the intensity of electromagnetic radiation.
6, pay attention to keep the skin clean. There is a lot of static electricity on the surface of the computer screen, and the accumulated dust can be transferred to the exposed skin of the face and hands. After a long time, it is prone to rash, pigmentation, and even skin lesions in severe cases.
7. Pay attention to nutritional supplements. When computer operators work too long in front of a fluorescent screen, the retinal rhodopsin is consumed, and rhodopsin is mainly synthesized by vitamin A. Therefore, computer operators should eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat and other foods to supplement vitamin A and protein in the human body. And drinking more tea, tea polyphenols and other active substances in tea will help absorb and resist radioactive substances.
4. The harm of playing computer frequently
1, memory loss
Not only the elderly, but many young people in their 20s today are also facing memory loss. This is due to the brain becoming saturated with too much secondary information, the culprit of which is the computer. A survey in Japan shows that more and more young people between the ages of 16 and 30 are increasingly dependent on information technology, which can lead to migraines, memory loss, confusion and concentration in addition to physical damage. Barriers to concentration.
2, writing amnesia
For people who use computers for a long time, especially those who are used to the Pinyin input method, It is often found that after getting used to the computer, when writing with a pen, I often cannot remember how to write some words. Experts believe that this is suffering from “writing amnesia”.
At present, computers are becoming more and more popular in our daily life, and writing with a pen seems to have become a thing of the last century. Writing can easily lead to a decline in writing ability, and feel unfamiliar with some commonly used words, not only the level of calligraphy is regressed, but the phenomenon of spelling and writing is becoming more and more common.
3, sympathetic nervous system disorders
Dizziness, insomnia, body aches, dry mouth… Long-term computer use This happens to everyone. In modern society, the computer has become an indispensable tool for people’s life and work, but it has increasingly become a “double-edged sword”: it brings people a lot of convenience, but also brings some pain, the above-mentioned The symptoms belong to the typical “stress syndrome” of the computer family.
5. What should children do if they like to play with computers
1, parents should lead by example and avoid computers
We all know that children are very curious, they are always full of interest in new and untouched things, and always want to try, so if parents often Playing on the computer and surfing the Internet in front of the child will definitely ask the child to try it. Once the child touches the computer, because the child is still young and has poor self-control, it is very likely to cause the child to become addicted to playing with the computer.
2, Control the time children play with the computer
Under normal circumstances, children of all ages play with the computer in moderation The time is as follows: children aged 3-6 in kindergarten should not spend more than 30 minutes a day in contact with computers; children aged 6-12 in primary school should not spend more than 1 hour a day in contact with computers, as long as they are in Time control can prevent the child from being addicted.
3Participate in more group activities
Mawang Encyclopedia reminds parents not to let computer games replace children’s normal growth Games in life, children should be integrated into real life, parents should encourage children to play and play games with their peers of the same age. If parents have time, they can also play more games with their children, which can not only improve intelligence and brain, but also enhance the relationship between children and parents.
4. Participate in outdoor sports
In today’s family, if both parents are at work, they usually It seems that there is no time to accompany the children. In many families, parents and mothers start watching TV or surfing the Internet after having dinner after get off work. When the time is almost up, they go to bed. On Saturdays and Sundays, they take a good rest and stop going out. But in fact, this is very bad for children. In such a life, children cannot feel the joy and warmth of being with their parents. From if children often play with computers alone, they will His growth caused a psychological shadow.
Six. What should I do if I work in front of the computer every day
1. Improve the working environment and purify the sundries next to the computer.
2. Take a break after working for a period of time, it is best to find a spacious area to stretch out a mood.
3. Put some green plants next to the computer, which can mainly ease the mood.
4. Drink plenty of water and eat foods rich in vitamins A, C and protein.
5. During the work period, protective measures should be strengthened. Pregnant women should wear shielding clothing, shielding caps and shielding glasses to reduce the stay time in the strong field area to prevent the damage of microwave radiation to the eyes.
6. For people who live a busy 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. Green tea can not only eliminate the harm of computer radiation, but also protect and improve eyesight. 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.
7. Before surfing the Internet, do a good job of skin care isolation, you can use some anti-radiation skin care products, which can effectively prevent the pollution and radiation of the environment; secondly, after the computer is used, a lot of electromagnetic radiation will be absorbed on the face. If there are particles, wash your face with water in time, which will reduce the radiation exposure by more than 70%!
8. Pay attention to indoor ventilation. Scientific research has confirmed that the computer screen can produce a carcinogen called brominated dibenzofuran. Therefore, it is best to install a ventilation fan in the room where the computer is placed. If not, pay special attention to ventilation when surfing the Internet.
