There is growing evidence that computers can be harmful to human health. It's not just a matter of time, it's a matter of time, and it's a matter of time.
▲ Microwave hazards: the computer's low-energy X-rays and low-frequency electromagnetic radiation, which can cause central nervous disorders. A British study confirmed that the low-frequency radiation and magnetic fields emitted by the computer screen can lead to 7 to 19 kinds of diseases, including runny nose, itchy eyes, neck and back pain, transient memory loss, irritability and depression. For women, symptoms such as menstrual cramps and prolonged periods will also occur, and a few expectant mothers may also experience premature labor or miscarriage. In addition, long-term computer operations, mental stress, psychological pressure, easy general fatigue, coupled with electromagnetic radiation, the incidence of breast cancer in female operators is about 30% higher than the general population. Relevant studies have also found that electromagnetic radiation from computers can also cause cancer; and with the popularization of computers and the Internet, a new modern disease called "computer syndrome" will make those who are engaged in long-term computer operations, programming personnel due to central nervous disorders caused by headaches, insomnia, palpitations, anorexia, nausea, and depression, slow thinking, easily irritated, and often feel tired. The best way to protect against computer microwaves is to make sure that the computer is not exposed to the microwaves. The best way to protect the computer microwave is to maintain a distance from it, the safest way to place the computer is the "back of the head" against the wall, the distance between each computer in more than 1 meter. There is no position, people and computer "back of the head" distance should also be maintained at more than 1 meter. If the computer time is too long, every 1 to 2 hours to leave 15 to 30 minutes, stand up and take a break, look out the window, breathe fresh air. Drink more tea, tea polyphenols and other active substances in the tea is conducive to the absorption and resistance to radioactive substances.
▲ Visual hazards: the use of computers, the eyes are most likely to be violated, especially easy to cause myopia and ciliary spasm in young people. These are known as "computer vision syndrome" is a stress-type disease, the reason is that the eyes stare at a place for a long time, the number of blinks only one-third of the usual, thus reducing the secretion of lubricant in the eye. This reduces the production of lubricant in the eye. Long-term effects such as eye fatigue, double vision and blurred vision can also lead to other discomforts. You should blink more in front of the screen to increase the secretion of tear glands and moisturize your eyes. The most effective way is to rest properly, eat more food containing vitamin A, supplement the retina of the retinal retinal retinal purplish red matter, such as carrots, cabbage, bean sprouts, tofu, jujubes, oranges, milk, eggs, animal liver, lean meat and so on.
▲ Tissue damage: the repetitive and tense movements of operating a computer can damage certain parts of the muscles, nerves, joints, tendons and other tissues. In addition to low back pain, those who suffer from carpal tunnel syndrome, in addition to wrist pain or even paralysis, these symptoms will extend to the palm of the hand and fingers. More exercise is the most effective way to overcome this computer occupational disease. The amount of exercise does not need to be too large, walking, lifting dumbbells and light aerobic exercise, can receive good results. The important thing is to be persistent. Often change ***, avoid working in one position for a long time. Adjust the table and chair to their own height. The correct height should be: sitting in a chair, elbows and keyboard lines should be parallel to the ground, the computer fluorescent screen should be placed in your line of sight a little lower, to ensure that when you look at the fluorescent screen, the neck slightly tilted upward, do not look up; feet should be placed flat on the ground, the chair should be smooth, the back feels comfortable.
▲ Respiratory hazards: The gas emitted by the computer can harm the respiratory system. British Allergy Foundation researchers recently published a study that office equipment will be released harmful to human health ozone gas, the main culprit is the computer, laser printers and so on. These ozone gases are not only toxic, but can cause breathing problems for some people. For those with asthma and allergies, the situation is even more serious. In addition, staying in places with high concentrations of ozone gas for longer periods of time can lead to lesions in the lungs. Rooms with computers should be ventilated by opening windows and doors frequently and placing small air fresheners or green plants near their seats to improve indoor air quality. Printers also produce *** sexual gases, *** nose and airways, should try to avoid prolonged exposure.
Drinking green tea can prevent computer radiation
Computer radiation is not only harmful to human health, but also affects the quality and efficiency of work. For people who live a stressful and busy life, the easiest way to ward off 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 not only can synthesize retinol, but also can make the eyes in the dark light to see things more clearly, so green tea can not only eliminate the hazards of computer radiation, but also to 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.
Help you reduce computer radiation
Technicians said that computer radiation is inevitable, but can be reduced. First of all, should be as far as possible to buy new computers, generally do not use the old computer, the old computer radiation is generally more powerful, in the same distance, the same type of conditions, generally 1-2 times the new computer. Operation of the computer is best in the display on a computer special color filter to reduce the harm of radiation, do not place indoor idle metal objects, so as not to form the re-emission of electromagnetic waves. When using the computer, to adjust the brightness of the screen, in general, the greater the brightness of the screen, the stronger the electromagnetic radiation, and vice versa, the smaller. However, can not be adjusted too dark, so as not to affect the effect of too little brightness, and easy to cause eye fatigue. Also note that the screen to maintain an appropriate distance. The closer the screen, the greater the electromagnetic radiation suffered by the human body, so the better is half a meter away from the screen.
Computer radiation damage to the skin, wash your face after the computer
Computers are becoming more and more essential supplies for work, dermatologists recently reminded the daily operation of the computer, be sure to wash your face after using the computer. The body and the computer screen should be as far as possible to maintain a distance of not less than 70 centimeters.
The amount of radiation generated by the computer screen is very small, but the accumulation of time will still damage the skin, easy to produce facial discoloration, the skin around the eyes appeared slack, crow's feet, bags and dark circles under the eyes. City dermatology hospital experts reminded frequent computer users, especially women, in the machine before it is best to apply some protective products, such as isolation cream or foundation. At the same time, it is best to use computer protection screen. After using the computer, it is best to wash your face often. Because long time in front of the screen, the skin is also prone to excessive oil secretion, dust accumulation. Before going to bed, after using the computer more need to clean the skin in time.
Computer radiation damage in the keyboard
Do you often feel heavy head or memory loss?
When you're sleeping on your stomach, remember to turn off your computer, not just your screen. It's not just about turning off the screen, it's about turning off the screen, it's about turning off the radiation, and it's about sleeping on your back with your head directly in front of the computer, so it's too late for Alzheimer's disease or a brain tumor.
You often sit at a computer desk, whether you sit for hours and hours and sit in an incorrect posture, always feel inexplicable shoulder and neck pain, and even distracted by work? Now please do a small test, please look to the left direction, and then head 45 degrees down slowly bent, action to do here, your neck, neck and shoulder whether you feel abnormal pain? If you have these symptoms, you should be careful, because you are likely to have a modern computer civilization disease - "thoracic outlet syndrome".
Do you know how much radiation a computer receives?
1, the keyboard 1000V / m
2, the mouse 450V / m
3, the screen 218V / m
4, the host 170V / m.
So, in your use of computers and enjoy the fun of surfing the Internet, please be more careful
Computer Radiation and Women's Health
Nowadays. Nowadays, a large number of professional women enter the management, business, finance, post and telecommunications, services and other organizations dealing with computers, according to relevant information, computer operators are mainly women, half of which are women of childbearing age. At the same time there are television, images, sound, computers, copiers, refrigerators, vacuum cleaners, microwave ovens, radio stations, cell phones, cordless phones, transmission lines and so on all electrical appliances produce electromagnetic radiation, and electromagnetic radiation has a very far-reaching harm to human health! The computer has changed women's lives in all aspects, and also affects women's fertility, beauty, physical and mental health in all aspects.
1, pregnant women should pay attention to electromagnetic radiation
Last year, the World Health Organization in the latest revision of the computer screen and work health issues, pointed out that in the computer screen work environment, some factors may affect the outcome of pregnancy, the recent study pointed out that pregnant women use the computer more than 20 hours a week, the rate of miscarriages increased by 80%, and also increase the rate of malformed children! Births. Last year, Sweden became the first country in the world to officially recognize that low-frequency electromagnetic fields with an intensity of 0.2 microtesla or more are harmful to humans.
2, electromagnetic radiation on the impact of beauty
Interviews, many recent close contact with VDT personnel complained of increased facial brown spots. Prof. Jin Xi introduced, foreign data repeatedly mentioned that VDT operator skin can appear red small blood rash, in the form of a line string, sometimes manifested as a symptom similar to erythema or eczema, mainly in the face, women are more. 1998 International Journal of Epidemiology reported: electromagnetic radiation leads to endocrine disorders in women is the main reason for a large number of chloasma breeding.
3, electromagnetic radiation leads to psychological stress and social incompetence
At the same time, according to a recent authoritative study funded by IBM and several other large companies announced that the computer network staff are prone to become more withdrawn, irritable, difficult to approach and social incompetence. Professor Huang also pointed out that the emergence of miscarriage and brown spots are also closely related to mental factors.
Computer radiation on the human body more or less some impact, but there is no basis for the standard, but pay attention to the following points can effectively reduce radiation, some of the misconceptions can be avoided to spend a lot of money.
1, the view of the screen is simply psychological comfort, now CRT monitors have anti-radiation anti-static coating, you can use your hand in front of the screen touch, there is no crackling static electricity, but to be free of radiation or recommended to choose the LCD screen.
2, the host to choose a better brand, such as Lenovo, etc., the chassis with only relatively thick, the interface are radiation seal, tight seams, placed under the table.
3, hard to rest, wash your face is a good way.
4, isolation cream and sunscreen simply do not work, isolation cream is to prevent dust-like substances, sunscreen is to prevent ultraviolet rays, do not prevent radiation components, do not have to spend money, but indoors coated with some of the sunscreen or to prevent refraction of ultraviolet rays, can only play a role in sun protection.
5, today's society more and more electronic devices, do not have to live so scared, even if you do not use the computer to watch TV ah, a variety of radiation in the air is also a lot of people do not have to worry too much.
How harmful is cell phone radiation to the human body?
Many medical experts believe that cell phones to achieve communication functions must receive and send powerful radio waves, in the use of cell phones, the strongest signal antenna part of the brain precisely close to the head, so it will certainly have a negative impact on the human head.
Jing Yanling, deputy director of the Qingdao Municipal Psychological Counseling Center, is one of the first psychiatrists in the city to focus on cell phone dependence. She on the "if you go out and forget to take the phone, what kind of reaction you have" to the public survey, the results of 25% of the people are extremely uneasy, trying to find ways to go home to get it; 50% of the people feel very inconvenient, but in general will not go home to get it; 21% of the people a little worried about it, but feel that the problem is not too big; only 4% of the people do not matter, but instead of feeling relaxed. 75% of the respondents would feel that forgetting their cell phones would bring them extreme uneasiness and great inconvenience. This shows that at least 80% of the citizens are more or less dependent on their cell phones.
From the main hospitals in the island city of ear, nose and throat to understand that in the last year or two, often received to the business, media personnel, etc. because of the long time to receive phone calls induced tinnitus and even mild deafness and other ear disease patients, which in the past is rarely seen. It may also cause neurasthenia, cataracts, testicular degeneration, physical fatigue, headaches, decreased immune function and other problems.
Therefore, we use cell phones in our daily life, the phone should not be in the waist, to prevent microwave damage to human internal organs (such as ovaries, liver and other organs), people and cell phones need to maintain the "beauty of the distance"; children, pregnant women, breastfeeding women should not use cell phones, at the same time, cell phone users should eat a diet rich in high-quality protein, phospholipids, B-vitamins, vitamins and minerals. The first thing you need to do is to get your hands on a new cell phone, and you'll be able to get it to work.
What is the harm that computer radiation does to the human body?
You have to pay attention to the four major hazards of computer radiation as follows:
1, computer radiation pollution will affect the human circulatory system, immune, reproductive and metabolic functions.
2, affecting people's reproductive system is mainly manifested in men *** lower quality, pregnant women occur spontaneous abortion and fetal malformation.
3, affecting people's cardiovascular system manifested as palpitations, insomnia, some women's menstrual disorders, bradycardia, decreased blood flow, sinus arrhythmia, leukopenia, decreased immune function.
4, the people's visual system has a negative impact on the eyes because the eyes belong to the human body on the sensitive organ of electromagnetic radiation, excessive electromagnetic radiation pollution will also have an impact on the visual system. The main manifestation of vision loss, causing cataracts and so on.
How harmful is cell phone radiation to the human body?
There are hazards for sure, but the consequences of the damage are related to many factors! You can refer to the following URL.
How much harm does computer radiation do to the human bodyThere are two aspects of health, one is physical health, the other is mental health. The most talked about computer harm is electromagnetic radiation. The use of computers during pregnancy can affect the normal development of the fetus. Women should pay attention to less contact with computers in early pregnancy, especially keeping a distance from the back and sides of the computer! Also, there are quite a few computer-related disorders nowadays, what "carpal tunnel syndrome", "computer vision syndrome", "computer rage", "Internet Dependence Disorder" ...... In short, both women and men should pay attention to protection when using computers. The vast majority of computer classrooms don't have CRT monitors placed properly! The first is to use a computer to monitor the computer, and the second is to use a computer to monitor the computer, and the third is to use a computer to monitor the computer, and the third is to use a computer to monitor the computer!
How big is cell phone radiation, and what are the hazards to the human body
I read a related report, and I'll pass it on to you
A thousand people have a thousand Hamlets. A few days ago, this newspaper forwarded a picture of Xinhua News Agency. The picture shows a four- or five-year-old boy talking on a cell phone, and its original intention was to show that cell phones are close to universal in Shanghai. But Mr. Xie Yichen, a physics professor from Jiamusi University, rushed to the newspaper for this purpose. Professor Xie said, beware of cell phone radiation, especially children.
Prof. Xie believes that the current controversy about the harm of cell phone radiation is only a discussion of the amount, not the question of whether there is. According to Prof. Xie, some media outlets have reported one-sidedly that "cell phone calls are not harmful to health", which is irresponsible.
Professor Xie analyzed the harm of cell phone radiation on the human body, can be understood from the well-known law of conservation of energy. Cell phones radiate microwaves outward, the nature of this radiation is the spread of energy, these microwave energy has a strong penetrating force, when they enter the human organ, according to the law of conservation of energy it will not be eliminated, it will be passed on to the human body organs, the conversion of these energies to other forms of energy: to produce thermogenic and non-thermogenic effects.
Prof. Xie explained some of the ambiguities.
People invented the microwave oven based on the thermogenic effect of microwaves. Some people would justifiably say, "I don't see anyone's brain being cooked by microwaves from a cell phone!"
Professor Xie explained that this is due to the difference in power, however, due to the use of cell phones in the use of close to the head, the emission of microwaves is very concentrated, so repeated prolonged use of cell phones, will certainly cause local lesions. About the cell phone radiation triggered eye cancer, brain cancer reports are common, it is worth mentioning that the latest issue of the European Journal of Cancer Prevention published an expert study of 1,617 brain cancer patients, long-term use of cell phones people suffering from eye cancer than those who do not use the chances of brain cancer 80% higher.
Some people may even say, "I've been using my cell phone for so many years, and nothing has happened." In this regard, the University of London research on human brain nerve cells of the scientists Gabriel pointed out that the cell phone cancer has a long latency period, it is difficult for people to see its harm, resulting in the use of cell phones, many people ignore the harm.
A large number of scientific studies have shown that microwave energy is transformed into a non-thermal effect of that part of the energy on the human body more serious harm. Experiments in the UK have reported that rats exposed to microwaves from a cell phone for five minutes can produce DNA lesions, which can be harmful to humans.
In view of the harm caused by cell phone radiation on the human body *** knowledge, countries around the world have developed safety standards for cell phone radiation, the United Kingdom *** expressly prohibit the use of cell phones by minors under 16 years of age; Japan *** stipulates that the sale of cell phones must be sold together with the cell phone radiation protection devices, and so on.
China's cell phone users have nearly 200 million, a considerable number of cell phone radiation is serious. In order to protect the health of hundreds of millions of nationals, Prof. Xie called on *** the relevant departments to promulgate our cell phone radiation safety standards as soon as possible and seriously implemented.
Cabinets with marble radiation in the end will be how big, what is the harm to the human body?
Any stone has radiation, artificial marble is also unprocessed from the stone powder, so there is also radiation, the size of the radiation specifically depends on the amount of radiation of the raw materials used in the manufacture of
What is the harm of cell phone radiation in the end on the human body?It is very clear to tell you that there is! This undoubtedly American researchers say that cell phone radiation can change human genes, although this report can not prove that cell phone radiation can damage DNA, but some experiments show that these radiations can lead to genetic changes in human blood cells; a British expert has also warned that the cell phone may release poisonous mercury gas, causing damage to the brain; induced Alzheimer's disease, Parkinson's disease, multiple sclerosis, harm fertility, aging and memory loss, and more and more frightening possibilities are being confirmed by scientists. Under the support of various standards, cell phone manufacturers and telecommunication experts believe that the use of cell phones will not be harmful to human health, and people in this camp insist that the electromagnetic radiation energy produced by cell phones is different from the strong electromagnetic wave energy produced by X-ray and nuclear radiation that destroys human cells and DNA molecular structure, destroys white blood cells in the human body, and induces cancer, and that the cell phone will heat up due to the electromagnetic wave that will be produced by the *** vibration during phone calls. warming phenomenon is also quite small and safe. However, many biology, medicine, environmental protection experts believe that playing the cell phone is harmful to health, their point of view is that the cell phone to achieve the function of communication must be uninterrupted with the transmitter base station to contact, and must need to receive and send strong communication radio waves, radio waves is the strongest place is the top part of the cell phone antenna. In the process of using a cell phone, the antenna is exactly the closest to the brain, so it must have a negative impact on the human brain.
How is computer radiation harmful to the human body?
As the saying goes, there is no such thing as gold. Computer, as a modern high-tech products and electrical equipment, in the life of people to bring more convenience, efficiency and joy at the same time, there are some harmful to human health unfavorable factors. Computer is radiation, to eat more food containing protein and carbohydrates, can be effectively prevented. Wish you health
What is the harm of computer radiation on the human bodyAnalysis: , computer radiation pollution will affect the human body's circulatory system, immunity, reproduction and metabolic function, serious will also induce cancer, and will accelerate the human body's cancer cell proliferation. ` 2, affecting people's reproductive system is mainly manifested in men *** lower quality, pregnant women spontaneous abortion and fetal malformation, etc. 2.}N 3, affecting people's cardiovascular system is manifested in palpitations, insomnia, part of the female menstrual disorders, bradycardia, cardiac blood flow, sinus irregularities, leukocyte reduction, decreased immune function, etc. 5S 4, the people's visual system has a negative impact on the eyes due to the eye belongs to the human body to electromagnetic radiation sensitive organs, excessive electromagnetic radiation pollution will also have an impact on the visual system. The main manifestation of vision loss, causing cataracts and so on.
