--------------------. Ha ha! If you are a girl, it will do more harm, such as irregular menstruation, long spots, or future fertility problems. If you can, change jobs as soon as possible, otherwise it will be bad for you! Br/ To minimize the harm, you can: br/ 1 Avoid operating the computer continuously for a long time, and pay attention to taking a break. To maintain a most appropriate posture, the distance between the eyes and the screen should be 4~5 cm, so that the eyes can look down or look down at the screen slightly. Br/br/ 2 A good working environment should be maintained indoors, such as comfortable temperature, clean air, proper anion concentration and ozone concentration. Br/br/ 3 The light in the computer room should be suitable, not too bright or too dark, so as to avoid the interference of light caused by direct illumination on the fluorescent screen. The studio should be kept ventilated and dry. Br/br/ 4 Color filters should be used on the screen of the computer to reduce visual fatigue. It is best to use glass or high-quality plastic filters. Br/br/ 5 Install protective devices to reduce the intensity of electromagnetic radiation. Br/br/ 6 Keep your skin clean. There is a large amount 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. Br/br/ 7 Pay attention to supplementary nutrition. When computer operators work in front of the screen for too long, rhodopsin on the retina will be consumed, and rhodopsin is mainly synthesized by vitamin A. Therefore, computer operators should eat more carrots, Chinese cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat and other foods to supplement vitamin A and protein in human body. Drinking more tea, tea polyphenols and other active substances in tea will help absorb and resist radioactive substances. Computer radiation caused acne
------------------------------. Therefore, it is necessary to control the online time, and the computer radiation causes acne
--------------------------.
Generally speaking, radiation will promote acne on the face, so it is best to surf the Internet less, but you don't have to worry too much about surfing the Internet normally.
The following information is for your reference:
What is the harm of computer radiation to the human body?
The radiation waves emitted by computers are often ignored by people. According to the international MPRⅡ radiation safety regulations, the radiation exposure must be less than or equal to 25V/m within a distance of 5cm.
but do you know how much radiation the computer emits? Radiation of computer: 1. keyboard 1V/m2, mouse 45V/m3, screen 218V/m4, host 17V/m5, Notebook25V/m
In addition, Radiation electromagnetic waves have eight harms to human body:
1, the promotion of cell canceration
2, abnormal hormones
3, intense loss of calcium ions
4, dementia
5, abnormal pregnancy
6, hypertensive heart disease
7, electromagnetic wave allergy
8, and the increase of suicides. `
2. The reproductive system of people is mainly affected by the decrease of sperm quality of men, spontaneous abortion of pregnant women and fetal malformation.
3. The cardiovascular system that affects people is characterized by palpitation, insomnia, menstrual disorder, bradycardia, decreased cardiac output, irregular sinus heart rate, leukopenia and decreased immune function in some women.
4. It has a bad influence on people's visual system. Because the eyes belong to the sensitive organs of human body to electromagnetic radiation, excessive electromagnetic radiation pollution will also affect the visual system. Mainly manifested as decreased vision, causing cataracts and so on.
The results of the latest national supervision and spot check on the quality of computer products announced by the General Administration of Quality Supervision, Inspection and Quarantine yesterday show that the electromagnetic radiation in computers cannot be ignored.
The General Administration of Quality Supervision, Inspection and Quarantine randomly selected computer products from 14 provinces and cities, including Beijing, Shanghai, Tianjin, Chongqing, Zhejiang and Hubei, and the sampling pass rate was 72%. It is understood that the results of this spot check show that the computing speed, multimedia functions and software and hardware support of computer products in the domestic market have been greatly improved, but the product quality level of some enterprises is not stable enough. In this spot check, the computer products of Stone, Hewlett-Packard, Muze and other well-known enterprises were also identified as unqualified products.
It is understood that the main quality problems found in this national inspection and spot check of computer product quality are that the indicators of radiation disturbance and conduction disturbance in electromagnetic compatibility exceed the standard. Radiation disturbance is a kind of electromagnetic wave interference emitted into space when the computer is working, which will affect the normal work of other electrical appliances, especially high-sensitivity electrical appliances. Conducted interference will affect the normal work of other electrical appliances in the same power grid, such as the motherboard, display card, switching power supply, monitor, keyboard, mouse, etc., which constitute the whole system. If it is not well selected, it will cause excessive radiation interference. During the spot check, it was found that some enterprises did not understand the standards well enough, and the control of parts purchase and assembly quality of production lines was lax, lacking the necessary testing means, resulting in unqualified products.
The seven companies, trademarks and models found in this spot check are:
Beijing Sitong Computer Technology Co., Ltd., Sitong, shocking JS1；;
Chongqing Xinbo Information Technology Development Co., Ltd., Xinbo, Freedom Village 111;
Nanning Shengli Technology Co., Ltd., Shengli, Leaping Ⅰ;
Shanghai botai computer technology co., ltd., botai, Bt-SMC-i3298;
Wuhan juxing computer co., ltd., Shennaotong, JXSD53L；;
Beijing Heyuan muze technology development co., ltd., muze, e fashion 51D；;
Shanghai hewlett-packard co., ltd., HP, P7281—L2325.
Uncover the X-files of computer radiation
As the saying goes, gold is not enough. Computer, as a modern high-tech product and electrical equipment, brings more convenience, efficiency and joy to people's lives, but there are also some unfavorable factors that are harmful to human health.
From the perspective of radiation types, the hidden dangers of computers to human health mainly include electromagnetic radiation (various electromagnetic rays and electromagnetic waves, etc.), sound (noise), light (ultraviolet rays, infrared radiation and visible light, etc.) and other radiation "pollution".
from the perspective of radiation sources, they include CRT monitor radiation sources, chassis radiation sources and peripheral equipment radiation sources such as speakers, printers and photocopiers. Among them, the imaging principle of CRT (cathode ray tube) display determines that it is difficult to completely eliminate harmful radiation during its use. Because when it is working, its internal high-frequency electron gun, deflection coil, high-voltage bag and peripheral circuits will produce many kinds of rays and electromagnetic waves, such as ionizing radiation (low-energy X-rays), non-ionizing radiation (low-frequency and high-frequency radiation), electrostatic field, optical radiation (including ultraviolet radiation, infrared radiation and visible light, etc.). Liquid crystal display, on the other hand, uses the physical characteristics of liquid crystal, and its working principle is completely different from CRT display. It is a "healthy" display with no radiation (negligible) and environmental protection. Various components inside the chassis, including CPU with high frequency and high power consumption, various boards with main chips with a large number of transistors integrated inside, optical drives, floppy drives and hard disks with high-speed DC servo motors, several cooling fans and transformers inside the power supply, etc., will emit radiation and noise interference such as low-frequency electromagnetic waves when working. In addition, external speakers, photocopiers and other peripheral equipment radiation sources are also a "source" that cannot be ignored.
judging from the degree of harm, electromagnetic radiation is undoubtedly the most harmful. Research by medical experts at home and abroad shows that long-term and excessive electromagnetic radiation will directly harm human reproductive system, nervous system and immune system, and it is the main inducement of cardiovascular disease, diabetes and cancer mutation, and the inducing factor of abortion, infertility and teratogenesis in pregnant women, and it can directly affect the development of body tissues and bones of minors, resulting in decreased vision, memory and liver hematopoietic function, and even lead to retinal detachment in severe cases. In addition, electromagnetic radiation also poses a hidden danger to information security, which can be received and decoded by special signal receiving equipment, leading to information leakage and unnecessary losses. Excessive electromagnetic radiation will also interfere with other electronic devices around and affect their normal operation, resulting in electromagnetic compatibility (EMC) problems.
Therefore, electromagnetic radiation has been listed by the World Health Organization as the fourth largest environmental pollution source after water, atmosphere and noise, and it has become an invisible "killer" that harms human health. Therefore, it is imperative to protect electromagnetic radiation.
There are clever ways to prevent computer radiation
When using a computer, it is best to equip a good-quality radiation screen in front of the monitor. Pay attention to eat more carrots, bean sprouts, tomatoes, lean meat, animal liver and other foods rich in vitamins A, C and protein, and often drink some green tea.
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.
computer radiation is inevitable, but it can be reduced. First of all, you should buy new computers as much as possible, and generally don't use old computers. The radiation of old computers is generally severe, which is generally 1-2 times that of new computers under the condition of the same distance and similar models. 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, it is necessary to adjust the brightness of the screen. Generally speaking, the greater the brightness of the screen, the stronger the electromagnetic radiation, and vice versa. However, it should not be too dark, so as not to affect the effect because the brightness is too small, and it is easy to cause eye fatigue. Also pay attention to keeping 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 better to be half a meter away from the screen.
After using the computer, many particles of electromagnetic radiation will be absorbed on the face. Wash your face with clean water in time, which will reduce the radiation exposure by more than 7%.
besides attacking bad people, cactus has another advantage! It is said that placing a cactus in front of the computer desk helps to reduce radiation.
People who often use computers will feel uncomfortable with their eyes, their eyesight will drop, and they will feel tired easily. People who often use computers should pay attention to the following aspects in their diet:
Eat some foods that are good for their eyes, such as eggs, fish, cod liver oil, carrots, spinach, sweet potatoes, pumpkins, medlar, chrysanthemums, sesame seeds, radishes, animal livers and so on.
Eat more foods with high calcium content, such as bean products, bone soup, eggs, milk, lean meat and shrimp.
Pay attention to vitamin supplement: eat more fresh fruits and vegetables containing vitamins.
Pay attention to enhancing resistance: eat more foods that enhance the body's disease resistance, such as mushrooms, honey, fungus, kelp, oranges and jujubes.
eat some anti-radiation food: although computers have little impact on human health, they should also be prevented. Drinking tea can reduce the harm of radiation, and lipopolysaccharide in tea has anti-radiation effect. Spirulina and sea buckthorn oil also have anti-radiation effects.
In addition, you should wash your face after using the computer, and pay attention to exercise at ordinary times.
the location of the computer is very important. Try not to let the back of the screen face people, because the computer has the strongest radiation on the back, followed by the left and right sides, and the front of the screen has the weakest radiation. As long as you can read clearly, the distance should be at least 5 cm to 75 cm, which can reduce the harm of electromagnetic radiation.
Pay attention to indoor ventilation: Scientific research has confirmed that the computer screen can 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.
it's not good to face the computer for a long time, so what should I do? In fact, four cups of tea a day can not only fight against radiation, but also protect your eyes.
1 a cup of green tea in the morning:
Green tea contains powerful antioxidants and vitamin C, which can not only remove free radicals in the body, but also secrete hormones against stress. A small amount of caffeine contained in green tea can stimulate the central nervous system and cheer up the spirit. However, it is best to drink it during the day to avoid affecting sleep.
2 a cup of chrysanthemum tea in the afternoon:
Chrysanthemum has the function of improving eyesight and clearing liver. Some people simply soak chrysanthemum and medlar together, or add honey to chrysanthemum tea, which is helpful to relieve depression.
3 Tired of a cup of Lycium barbarum tea:
Lycium barbarum L. is rich in beta carotene, vitamin B1, vitamin C, calcium and iron, and has the functions of nourishing liver, kidney and improving eyesight. It is sweet in itself, and can be used as tea or as a snack like raisins, which is effective in solving the problem of "computer family" eye astringency and fatigue.
4 a cup of cassia tora tea in the evening:
Cassia seed has the functions of clearing away heat, improving eyesight, nourishing brain marrow, calming liver qi and benefiting bones and muscles. People with constipation can also drink it after dinner, which is very effective in treating constipation.
There are also some teas or snacks that are most suitable for computer families, which can not only help you fight against radiation, but also protect your eyes and resist irritability.
mung bean and coix seed soup
mung bean and coix seed can clear away heat and toxic materials, induce diuresis and reduce swelling, while coix seed can strengthen the spleen and stop diarrhea, lighten the body and replenish qi. For workers who often need to stay up late or are upset, thirsty, constipated and have acne, in addition to eating more fruits and vegetables and supplementing water, eating mung bean and coix seed soup as a snack is very helpful for relieving summer heat and removing annoyance.
Eucommia ulmoides Oliv.
Eucommia ulmoides Oliv. has the functions of enriching blood and strengthening bones and muscles. It is very helpful for sedentary people with low back pain. It can be drunk by both men and women.
