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 viewing effect because the brightness is too small, which is easy to cause eye fatigue.
When operating the computer, pay attention to 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 be 0.5M away from the screen. In addition, after operating the computer, many particles of electromagnetic radiation will be absorbed into the face. Washing your face with clean water in time will reduce radiation exposure by more than 70%.
How to avoid being polluted by electromagnetic radiation
With the rapid development of science and technology, various scientific and technological products and household appliances have entered people's lives, which have greatly improved people's work efficiency and improved people's lives. I can't imagine what people's life would be like without these live broadcast devices. However, with more and more high-voltage electricity and transmission towers around the city, there are more and more electrical equipment at home, which makes people feel convenient and hurt at the same time. At present, electromagnetic radiation pollution has become the fourth largest environmental pollution after water, air and noise. What would you do if one day, the house you live in was suddenly told that it was in serious electromagnetic radiation? Among the many household appliances, can you find out which ones have higher radiation? What is electromagnetic radiation? From a professional point of view, electromagnetic radiation is a phenomenon that energy propagates through space in the form of electromagnetic waves. Almost any electrical appliance in our home will produce electromagnetic radiation. Such as microwave oven, TV, computer, mobile phone and so on!
What is the difference between electromagnetic radiation and electromagnetic radiation pollution?
Actually, electromagnetic radiation and electromagnetic radiation pollution are two concepts. Any charged body has electromagnetic radiation. When the intensity of electromagnetic radiation exceeds the national standard, it will have negative effects and cause different diseases and harms to the human body. This part of radiation that exceeds the standard electromagnetic field strength is called electromagnetic radiation pollution.
What harm will electromagnetic radiation do to human body?
Because everyone's body resistance is different, everyone will have different degrees of symptoms. Generally, being polluted by electromagnetic radiation will cause central nervous system problems such as headache, insomnia and arrhythmia. At the same time, it may affect some people's eyes, such as decreased vision, skin diseases and even cancer. For pregnant women who may cause miscarriage, the elderly who have installed pacemakers should pay special attention. At the same time, different people or the same person have different tolerance to electromagnetic radiation at different ages. Even in an environment exceeding the standard, it does not mean that everyone will get sick, so there is no need to "be a soldier" for electromagnetic radiation. However, preventive measures should be taken for the elderly, children, pregnant women or patients with pacemakers, people who are sensitive to electromagnetic radiation, and people who work in excessive electromagnetic radiation for a long time.
What items produce electromagnetic radiation?
The household appliances used in our life all have a certain amount of radiation, but the brands produced by regular manufacturers generally meet the requirements, and the electromagnetic radiation will not exceed the standard and will not bring harm.
Professionals walked into a resident's home and conducted a field test on the electromagnetic radiation in this gentleman's home!
Mr. Zhang is a civil servant. Because of the need of work, he has many electrical appliances at home, including three optical computers, two televisions and two microwave ovens. In addition, other electrical equipment running at the same time will definitely release a lot of electromagnetic radiation. He heard from his friends that electromagnetic radiation pollution may cause harm. In order to ensure the health of his family, he specially invited professionals to conduct a comprehensive test at home.
Usually computers are used the most. From here on, the tester shows that it is around 0.03, and it seems to be higher around the TV, between 0. 1-0.08. Mobile phones are often used. The test result is 0.3, which is significantly higher than the other two items.
After testing, the microwave oven at home has the highest radiation. Is the radiation in the microwave oven exceeding the standard? According to the technical staff of the Indoor Environmental Testing Center, the radiation amount is qualified within the scope stipulated by the state, so it seems that Mr. Zhang's family need not worry.
What measures should we take to prevent electromagnetic radiation?
Although electromagnetic radiation is harmful, in this electrical age, these hazards can be greatly reduced as long as some active and effective protective measures are taken.
One of the most effective preventive measures is to buy some protective equipment, which is necessary for housewives, pregnant women and people who operate computers for a long time.
Protective clothing: including coats, vests, aprons and maternity clothes. Made of special fiber, it has good anti-electromagnetic radiation and anti-static effect. Especially for families with microwave ovens, it is best to equip them with protective aprons, which can effectively prevent electromagnetic radiation. For pregnant women, if they come into contact with electrical equipment, they must wear protective Chinese-style chest covering or protective clothing to ensure the healthy growth of the fetus.
Radiation shielding: it has many functions such as radiation protection, anti-static, anti-glare and so on, and it also plays a certain role in protecting eyesight.
Another way is to pay attention to time and distance.
The degree of injury is proportional to time, that is to say, the longer the exposure to electromagnetic radiation, the greater the injury. Is inversely proportional to the distance, the distance is ten times larger, the radiation is one percent of the original, the distance is one hundred times larger, and the radiation is one ten thousandth.
Specific household electrical equipment protection is divided into:
First, the microwave oven
Vigilance index: ★★★★★★★
Microwave ovens use the thermal effects of microwaves to heat and cook food. Studies have shown that the strong electromagnetic waves generated by microwave ovens may cause diseases if they exceed the standard seriously.
Coping methods:
1. It is best to leave about one meter after the microwave oven is turned on.
2, often use the microwave oven to cook food, you can wear a shielded apron and a shielded jacket.
3. It is best to replace the microwave oven after 6 to 7 years of use.
Second, computers.
Warning index: ★★★★
Coping methods:
1. If you have to use the computer for a long time, you should pay attention to washing your face in time.
2. When using the computer, you should keep the correct posture, and the distance between people and the computer screen should be kept above 70CM.
3. The electromagnetic radiation intensity on the back and side of the computer is not less than the screen, and should be kept above 120CM.
4. Liquid crystal is less harmful to human body.
Third, TV sets.
Early warning index: ★
Coping methods:
1, TV sets should not be too concentrated with other electrical appliances, exposing themselves to the danger of excessive radiation.
2. The distance between TV and people should be at least 2 meters away and not too close to the screen.
It is best not to put TV and other electrical appliances in the bedroom.
In addition, it should be noted that reading books and newspapers in bed is a kind of life interest for many people. However, small household appliances such as radio, walkman and mobile phone are not suitable for bedside to avoid electromagnetic radiation.
Finally, if you are in the electromagnetic radiation source for a long time and feel unwell, you should find relevant departments for monitoring and testing as soon as possible to find out the radiation source. Avoid long-term injuries.

How to maintain your body?
Facial protection
Although surfing the Internet is not the enemy,
However, for severe electromagnetic radiation, we still need to do foot and face work.
Screen radiation produces static electricity, which is the easiest to absorb dust. Face to face for a long time is more likely to lead to spots and wrinkles. Therefore, before surfing the Internet, you may wish to apply skin care lotion and add a layer of calomel to slightly increase skin resistance.
Thoroughly clean the skin
The first task after surfing the Internet is to clean the skin, thoroughly clean the face with warm water and cleanser, wash away all the dirt adsorbed by static electricity, and apply mild skin care products. Long-term use can reduce injuries, moisturize and beautify. This is really a little trick and a big role for women who surf the Internet.
Step 3 keep your eyes bright
If you don't want to see a person with red eyes, dark circles and gaunt face the next day, don't fight continuously for a long time, especially don't stay up late surfing the Internet. Prepare a bottle of eye drops at ordinary times in case of emergency. It is also good to apply cucumber slices, potato chips or frozen milk and herbal tea after surfing the Internet. Its method: slice cucumber or potato, apply it on double eyelids, and close your eyes for a few minutes; Or use gauze to soak frozen milk herbal tea and apply it to eyes, which can relieve eye fatigue and nourish skin around eyes.
Increase nutrition
It is very important to increase nutrition for people who often surf the Internet. Vitamin B group is very beneficial to mental workers. If you go to bed late, the quality of your sleep is not good. You should eat more animal livers and fresh fruits and vegetables, which are rich in vitamin B group. Meat, fish and dairy products increase memory; Chocolate, wheat doughnuts, seafood and dried fruits can enhance the coordination of the nervous system and are the best snacks when surfing the Internet. In addition, drinking Lycium barbarum juice and carrot juice from time to time also has obvious effects on eye protection and skin care. If you care about your appearance, quit those carbonated drinks and drink carrot juice or other fresh juice instead.
5. Do gymnastics regularly
After surfing the Internet for a long time, you may feel dizzy, stiff fingers, backache, and even edema and varicose veins of lower limbs. Therefore, we should do gymnastics at ordinary times to maintain vigorous energy, such as lying flat on the bed before going to bed, relaxing the whole body, and putting our head back below the edge of the bed after use to alleviate the lack of blood supply and oxygen supply to the brain; Raise your feet and lie flat on the bed or sofa to reduce foot edema, help blood return and prevent varicose veins of lower limbs; Stretch from time to time during surfing the internet, stretch your muscles or lean on a chair, push your hands back, and stretch your tense and tired waist muscles; Shaking your fingers is the easiest way to completely relax your fingers. Remember, this kind of gymnastics does not exercise much, but it is far more effective than sleeping late.
Three fatal injuries to the skin caused by computers
Computer damage to the skin-
First: dry skin, fine lines and yellow complexion.
Second: there are spots.
Third: there are fine lines in the eyes and serious dark circles.
Many friends have been telling me that long-term computer work has caused the above three skin problems, hoping to solve them.
Let's talk about dry skin first
I think we all understand the truth, but we just want to get a solution. Let's talk about dry skin first, and computer rays invade the skin. So far, there are no preventive measures, but this does not mean that the skin dryness caused by computer work cannot be solved.
Authoritative experts believe that mental stress will lead to endocrine system disorder and persistent psychosomatic dysfunction, resulting in dry and loose skin, loss of luster and morbid skin color. This phenomenon is called "skin disorder syndrome", which will accelerate skin aging and hinder skin bodybuilding.
The blood circulation of the skin has nothing to do with biological functions such as secretion and excretion, but is controlled and regulated by autonomic nerves, which are governed by the central nervous system of the brain. Therefore, people's mental activities can affect the color of facial skin and are closely related to the occurrence of skin diseases. Based on the above statement, we can sum up that it is good for the skin to arrange some time to relax, go to clubs for leisure exercise, go to beauty salons for music therapy, or relax through exclusion.
In addition to liberating yourself spiritually, you need to work hard on skin care. I have repeatedly stressed that the skin should be thoroughly cleaned and maintained in different ways according to the condition of the skin that day. It is best to use products that can repair the skin, help the skin artificially, and quickly recover to a healthy state on the same day. Replenish water to make the stratum corneum drink enough water every day to eliminate the phenomenon of dry skin, whether it is skin collapse, peeling, temporary fine lines, or redness and sensitivity of the skin.
Pay attention to skin whitening
Pay attention to the maintenance of skin basement membrane, which is responsible for the transmission and communication between epidermal and dermal cells, and is of greater significance to skin maintenance.
Guerlain's day cream for softening and firming skin, CD's revitalizing essence and double anti-wrinkle lotion, Shiseido's vivid and shiny maintenance series and Estee Lauder's crystal whitening series can all improve skin tone.
These products not only use effective whitening ingredients and technologies, but also have a new understanding of skin whitening, so that whitening is not limited to inhibiting the production of melanin, but a three-pronged approach of prevention, repair and whitening, so that the skin is not only white, but also whiter, clearer, smoother, brighter and clearer.
Eye problems
Working on the computer for a long time not only makes my eyes sour, but also sometimes makes my eyes blurred and I can't see clearly. This is caused by my excessive use of my eyes. The skin problems of my eyes are dark circles, increased fine lines and bags under the eyes. These questions are really a headache So how can we prevent and solve these problems in my eyes?
Eye care, massage in the eye can improve blood circulation and help eliminate dark circles, but don't overdo it, otherwise it will make the eye muscles droop. Use eye gel containing chamomile, green tea and cucumber once a week.
Bags under the eyes do harm the appearance, and once they are formed, they are difficult to eliminate. Long-term computer work will make eyes overtired, blood vessels dilate and eye muscles swell. At this time, you can close your eyes and apply a cotton pad to your eyes with frozen aloe juice, and lie still for a few minutes to improve the swelling. Don't ignore this edema phenomenon, which eventually accumulates into serious bags under the eyes, so we have to solve it surgically.
Long-term use of eye fatigue, fine lines quickly climb to the eyes, you can tighten the water every day (eye-specific). Apply cotton to your eyes, or you can use eye mask. Sticking it once a day can quickly eliminate fine lines. If the fine lines become thick and deep wrinkles, it will be too difficult to maintain, so pay attention to the fine lines in the eyes and don't make them worse!
You can install a screensaver, or put more cream on your computer! This can reduce radiation!
If your monitor is relatively new, you should support a refresh rate of 85Hz, so that the displayed image will not flicker, shake or be unclear. This setting is usually enough. If the older one may only support 75Hz, it is also possible that the effect of 70Hz is slightly better than 75Hz, depending on the quality of your monitor.
The resolution usually uses the recommended values of 1024*768 and 17 inch monitors. If you do word work and your eyesight is not very good, you can adjust it to 800 * 600; If you want to make a Cad drawing, you'd better use 1024*768 to set the taskbar to hide automatically.
If you adjust the refresh frequency of the monitor to the above values respectively, you will see different display effects after careful observation, which may not be very different, which is related to your own eyes. Some people are sensitive to the flicker of light, while others feel nothing.
In addition: 1. It is suggested to drink more green tea, which can reduce the radiation hazard of monitors.
2. Can you consider replacing CRT monitor with LCD to protect your eyes? Maybe you have no right?
It is harmful to the skin. Computers have radiation and static electricity, which easily attract harmful substances such as dust. It is recommended to use them for a long time.
In the face of computer needs, eat more fruits and wash your face frequently. Computer skin is actually a skin problem caused by modern people, especially the younger generation, who often contact computers.
Because computers have certain radiation sources, including keyboards, computer screens, mobile phones, etc., which are quite powerful radiation sources. These radiation sources will directly affect the stability of our endocrine system. So that the skin metabolism is irregular and so on. In addition, computers are magnetic and will accumulate some dust and unclean air. It will affect the quality of our skin and the aging degree of our skin.
You see, an unstable internal adjustment and an external environmental factor have caused various problems to our skin.
For each different type of skin, the performance is different:
Like oily skin, it will show that the oil situation is very serious, or at the same time the face begins to dry, that is, lack of water, acne, large pores and so on;
Dry skin is characterized by dry skin, fine lines, dullness and dark spots. Well, these are all the results of sitting in front of the computer for a long time and ignoring how to protect it ~
There is also mixed skin, which usually has the characteristics of dry and oily skin, usually T-zone oil and dry cheeks. Facing the computer, the characteristics of the two skin types are becoming more and more obvious.
Then there is the aging of eye skin and the blurring of eye optic nerve.
And computer skin has a lot to do with our environment. For example, friends sitting in office buildings usually work in an air-conditioned environment. Eight hours in front of the computer. And if the internal adjustment, radiation protection, hydration and moisturizing work are not in place, the skin will become dry, dull and oily, and more seriously it will show the characteristics of sensitive skin!
How to solve computer skin?
In terms of internal adjustment, try green tea and chrysanthemum tea, two weakly alkaline teas.
Everyone knows that green tea not only has anti-cancer effect, but also can scavenge free radicals in the body and has anti-radiation effect. Drinking some green tea every day is very beneficial to your health.
Chrysanthemum tea is a kind of fragrant tea. Its beauty lies in that when your eyes are tired, you can fumigate your eyes with the hot air of chrysanthemum tea for 1 minute, and your eyes will feel very comfortable immediately. You might as well try.
On the issue of internal adjustment, we should usually eat more foods that help to resist oxidation, such as foods containing vitamin A, vitamin C and vitamin E. Yang Fei often puts A, C and E together. Because they are really a super antioxidant combination! Rich vitamin C can be taken from various vegetables and fruits, especially fruits, because it is water-soluble;
Both A and E are fat-soluble, especially vitamin A, which is found in all kinds of yellow vegetables. It is recommended to fry in oil. Especially carrots, but I found that many friends don't like them. But in fact, carrots are rich in carotene, also known as beta carotene. Only by frying in oil can you really release carotene, otherwise you will only eat carrot precursors raw!
Carotene can not only help our skin to be refined, moisturized and hydrated, but also help to "naturally control oil". Balance water and oil secretion and make our eyes bright.
As we all know, there are two kinds of facial skin: sweat glands and sebaceous glands, while the skin around the eyes has only sweat glands and few sebaceous glands, which is one reason why the skin around the eyes will age before other facial skin. With so much vitamin A, our water and oil will be balanced and our skin will be tightened ~
Let's talk about vitamin e. It is also called reproductive alcohol, and it has many uses. For people with computer skins, it is very effective to eat some natural vitamin E, such as animal viscera and various beans, to help protect our cell walls. Thereby enhancing the antioxidant capacity of the skin.
Usually pay attention to drink more water every day, preferably 2500 ml. For example, 1 bottle of mineral water is 550ML, which is about 4 bottles. Keep the daily urine volume 1000 ml. Eat more weakly alkaline foods such as vegetables and fruits, keep your body weakly alkaline, and eat less acidic foods, so that your skin will gradually improve.
That's the internal tuning part. Now let's see how to make external improvements according to different environments and skin types:
1, for oily skin, you must do a good job of hydrating. No matter what kind of skin care products you choose, it is important to replenish fresh water without oil. Choose weakly acidic cleansing products, not alkaline ones. Because the alkaline ones will be washed very clean at that time, but after 1 2 hours, oily skin will become serious, especially in the T area and cheeks, which is also a point with large pores. Therefore, Yang Fei reminds everyone to remember to use weakly acidic cleansing products ~ How to distinguish the acidity and alkalinity of cleansing products? Go to the drugstore to find PH test paper.
2. In terms of emulsion, alcohol-free emulsion and moisturizing emulsion are used. In fact, oily skin is the most in need of hydration. Instead of controlling oil. Only replenishing water can help control the oil stain on the surface. The more oil, the less water is secreted, which is why people with oily skin are prone to dehydration.
3. Ok, now the third one is acne. People with oily skin are either internal or external. When they are not careful, pimples take the opportunity to enter ~ from your beautiful skin, people break out of the cocoon and we break out of the skin.
For acne, we should adopt the method of internal and external attack. In essence, in addition to strengthening the amount of drinking water and maintaining the daily breakfast, it is necessary to eat more fruits and vegetables and less meat, greasy food and sweets. Many friends don't know, in fact, sweets are the most prone to acne. Because sweets will slow down the metabolism of vitamin B group in the body and grow blackheads, because T area is the most abundant place of sebaceous glands, and the metabolism of B group will slow down, then T area will be more oily. So it is also important to put an end to sweets!
For external use, use a fresh, fat-free and weakly acidic basic nursing suit with internal adjustment. You know, 80% internal care plus 20% external care, as well as your good mood every day, will really improve your skin.
4, oily skin, another point is to do exfoliation work every week and clean the mask. At the same time, don't forget to replenish fresh water to your skin:) Replenishing water will also make your pores converge.
Now talk about dry skin, sitting in front of the computer how to improve it?
For dry skin, pay attention to the ingredients containing long-lasting moisturizing factors when choosing the basic suit. For example, Sandi often shares some moisturizing star ingredients with friends, such as mucopolysaccharide, collagen, hyaluronic acid and so on. Ah, this hyaluronic acid should be regarded as a new moisturizing star:) Now many kinds of skin care products contain it ~ The moisturizing effect is also good for me!
In addition to moisturizing, it is hydrating. Moreover, hydrating and moisturizing are two completely different concepts. The skin should be hydrated first to help cells drink enough water, and then moisturized to help water retain water for a long time.
With sufficient moisture, the skin should first avoid being sensitive. And ready to moisturize. At the same time, the work of skin hydration is very good, and dry skin is not easy to cause fat particles!
Speaking of fat particles, in fact, one of the reasons for its formation is that the skin is dry and there are small wounds. When we use it again to maintain the skin, it will cause hair follicle keratinization, which is fat particles.
Besides moisturizing, choose long-acting moisturizing factors, such as hyaluronic acid and allantoin. Although the name allantoin is not pleasant to hear, it is the savior of dry and sensitive skin and can play a very good soothing role! And chamomile, a chrysanthemum substance, is also anti-allergic.
Why put dry and sensitive skin together? It is because dryness is very easy to become sensitive skin:)
Here, external maintenance should pay attention to hydrating and moisturizing.
In terms of internal adjustment, it is good to supplement collagen, whether you take it from pectin of fruit, bone soup or skin. Help skin shine and moisturize:)
And mixed skin, oily, refer to oily practices, pay attention to replenish refreshing water; For dryness, refer to the method of dry skin and pay attention to long-term moisturizing:)
Now let's pay attention to sensitive skin. This kind of skin can't stand the dry and air-conditioned environment. The skin will be dry and prone to cold and hot facial flushing. There are spots and acne. The most important thing to deal with such skin is to hydrate and moisturize. Because sensitive skin has thin cutin, it is not recommended to use exfoliating things, but pay attention to hydrating and moisturizing to help cells enhance their resistance, so that they are not afraid even in the face of high altitude and computers ~
With a spray:) the soothing and moisturizing type is very good. No matter what skin type you are, a spray can release your nervous mood.
Don't forget to use eye cream for the above four different skin types:) Because the aging degree of eye skin is also very fast. You can use alcohol-free, essence-free and non-irritating moisturizing toner as a base to help moisturize your eyes. The effect will be very good
Pay attention to these points:)
In fact, some of them are also crucial. For example, you can buy some cactus and put it next to the radiation source to help us absorb some radiation. Using sunscreen every day can help the skin create a good environment, isolate dirty air and make-up; There is also eating some seafood, such as kelp and spirulina, which are very good anti-radiation foods.
Usually the food is mainly green, so I have a good habit of eating more weakly alkaline food:)
It is suggested to move the chassis farther away and turn down the brightness of the notebook. You might as well close your notebook. Usually, the desktop is much more radiant than the notebook.
