The harm to the body is as follows: Symptom 1: Electromagnetic radiation: insomnia, endocrine disorders. Reason: When the monitor is too hot, there will be a lot of electromagnetic radiation when it works, which will ionize the air, constantly produce positive charges (positive ions), and constantly neutralize the negative ions in the air, resulting in almost zero negative ion content.
The more beneficial negative ions, the more harmful positive ions. Being in an environment with too many positive ions for a long time, it enters the lungs through breathing, and then it is transported to various tissues of the human body with blood circulation, which makes people's blood and body fluids acidic, delays the normal metabolic function of the body and accumulates toxins in the body. Causes insomnia, decreased immunity, and female endocrine disorders.
Relief method: 1. Clean the office environment carefully. Because positive ions will be firmly adsorbed on dust particles, the more dust, the more positive ions.
2. Drink more tea. Tea polyphenols and other active substances contained in tea help to absorb radioactive substances.
3. Most of the radiation emitted by the display does not come from its front, but from its sides and back. So, don't point the back of the monitor at the back of your colleague's head or the side of your body.
4. Drink green tea often. Green tea is the most talked about health drink in recent years, because it contains powerful antioxidants catechol and vitamin C, which can not only eliminate free radicals in the body, but also make the accessory renal cortex secrete hormones against stress, greatly improving the mood.
But it is best to drink it during the day, so as not to affect sleep. 5. Mung beans can clear away heat and detoxify, induce diuresis and reduce swelling, and coix seed can strengthen the spleen and stop diarrhea, and lighten the body and replenish qi. Often need to work late or when fidgety, dry mouth, constipation, it is very helpful to eliminate fidgety.
6. Washing your face often can prevent radiation waves from harming your skin. 7. Put a pot of plants or water under the computer desk to absorb the electromagnetic waves emitted by the computer.
8. Try to use LCD monitors. 9. Wear a radiation-proof Chinese-style chest covering.
Count 2: Symptoms of dust field: Causes of skin allergy: When the monitor is turned on, an electrostatic field will be formed around it, which will almost suck the dust suspended in the air of the whole room into its own field, thus causing facial skin to suffer from * * *, resulting in allergic skin rash. Sitting in front of the computer, your surroundings are full of air containing a lot of dust particles, so the user's skin is very prone to allergic phenomena such as rash.
Relief method: 1. Don't put mountains of papers and documents around the computer, but put all the necessary documents in the cupboard in different categories, because the dust on papers and documents is usually difficult to clean up. 2. Wipe the surface of the computer desk with a wet cloth dipped in antistatic agent.
3. Always open the window for ventilation. 4. Rub some moisturizing cream on your face before using the computer, or soak the towel with chamomile extract (a simpler method is to use a wet chamomile tea bag) and apply it directly to your forehead and cheeks.
5. Put a cactus on the computer desk, because the acupuncture of cactus can absorb dust. 6. Clean the keyboard frequently. Wash your hands when and after using the keyboard and before eating. Cover the keyboard with a cloth when not in use.
Because the keyboard is uneven, it is very easy to accumulate dust, which will become a hiding place for skin diseases and cold germs. Count three: the picture flashes and heats up, causing the environment to be dry. Cause of dry eye: Although it is invisible to the naked eye, the picture on the monitor has been flashing.
When looking at the monitor, we often stare at a certain point for a long time and rarely blink, so the eye muscles are easy to get tired, the eye mucosa is dry, and the eyes are red, swollen and painful. Almost everyone's eyes will feel sore and trachoma after working in front of the computer for 4 hours without interruption.
The working environment of computer workers is closed, the humidity in the environment is low, and the computer keeps heating up. In a dry environment, the tear layer will evaporate in a few seconds, which has become an important cause of dry eye. Relief method: 1. It needs to be more than 70cm away from the display, slightly below the line of sight of both eyes, and try to reduce the area of the eyeball exposed to the air.
2. Adjust the brightness to a level that won't make your eyes tired. When working in front of the computer, the room should not be too dark or too bright.
The ideal office environment is that the brightness of the room is the same as that of the screen. 4. Because you want to avoid the images of your face, lights and objects on the screen (all light and shadow will double the fatigue of your eyes), you should avoid the direct illumination of indoor light on the screen to produce interference light.
The light source should preferably come from the left or right side of the computer user. If you wear glasses, you should buy yourself a pair of lenses with anti-reflective coating.
In order to prevent conjunctival dryness, we should drop some eye drops with the same composition as our tears when using the computer. 6. When eyes are tired, apply a wet towel boiled with light black tea for a few minutes, which will quickly eliminate congestion and fatigue.
7. Stir-fry 500 grams of black beans, cool and grind into powder. 500 grams of walnut kernel, slightly fried, stripped, cooled and mashed into mud.
Take the above two foods 1 spoon, pour them into 1 cup of boiled milk, add 1 spoon of honey, and take them in the morning or after breakfast. It can strengthen the muscle strength in the eye, strengthen the regulation function and improve the symptoms of eye fatigue.
Count 4: Symptoms of long-term mouse use: Mouse hand (wrist joint syndrome) Reason: Long-term use of computer keyboard and mouse may be associated with a disease called wrist joint syndrome, resulting in pain and numbness of index finger or middle finger, muscle weakness of thumb, which may lead to nerve damage, and then hand muscle atrophy. The problem is that knocking on the keyboard or moving the mouse repeatedly every day leads to long-term, intensive, repetitive and excessive activity of the wrist joint, which leads to injury or oppression of peripheral nerves and blocks nerve conduction, thus causing sensory and motor disorders of the palm.
In addition, the elbow is often lower than the wrist, the hand is held high, the nerve and tendon are often compressed, the hand will start to numb, the fingers will lose flexibility, and joint pain often occurs. Frequent exertion of fingers will also damage the nerves and muscles of hands and related parts due to excessive fatigue, resulting in a series of symptoms such as ischemia, hypoxia and numbness.
The survey shows that women have more "mouse hands" than men, because women's wrists are usually smaller than men's, and the median nerve of the wrist is easily oppressed. Relief method: 1. Try to avoid the upper limbs being in a fixed, mechanical and frequent working state for a long time. When using the mouse or typing, get up and move your limbs and do something every hour of work.
2. What should I do if I play computer too much?
Matters needing attention in peacetime;
1, pay attention to develop good hygiene habits: when operating a computer, you should wash your hands after work because you have more contact with the computer keyboard to prevent infectious diseases.
2. Keep your skin clean: Always keep your face and hands clean, because there is a lot of static electricity on the surface of the computer screen, and the accumulated dust can be transferred to the skin of the operator's face and hands. If you don't pay attention to cleaning, after a long time, it is easy to appear ugly spots and pigmentation, and even cause skin lesions in serious cases, affecting beauty and physical and mental health.
3. Pay attention to nutritional supplement: computer operators working in front of the screen for too long will consume rhodopsin on the retina, which is mainly synthesized by vitamin A. Therefore, computer operators should eat more carrots, Chinese cabbage, bean sprouts, red dates, oranges, milk, eggs, animal livers, lean meat and other foods to supplement vitamin A and protein. You can drink more tea at ordinary times, because tea contains active substances such as tea polyphenols, which can absorb and antagonize radioactive substances and protect human cognitive function and heredity to some extent.
4. Pay attention to the correct posture: the seat should be straight and comfortable when operating. The center of the computer screen should be installed at the same height as the operator's chest, and the distance between the eyes and the screen should be 40-50 cm. It is best to use a chair with adjustable height. During the operation, you should blink or close your eyes for a while frequently to adjust and improve your vision and prevent it from declining.
5. Pay attention to the working environment: the light in the computer room should be suitable, neither too bright nor too dark, so as to avoid the interference of light caused by direct irradiation on the fluorescent screen. Regularly remove indoor dust and microorganisms. When cleaning, it is best to disinfect the air filter with a wet cloth or a warm mop, adjust the air volume reasonably and change the fresh air. If you are doing computer operations at home, you should also try to refer to your heart and use protective screens to minimize the harm of electronic radiation to the human body.
6. Pay attention to the combination of work and rest: Generally speaking, computer operators should rest for about 1 0 minutes after continuous work. Moreover, it is best to exercise your hands and feet and torso outside the operating room, take a walk, do radio exercises, take the initiative to rest, or do eye exercises, and exercise your head indoors (many people complain about cervical pain, and moving your head will help).
7, pay attention to protect your eyesight: protect your eyesight, in addition to regular rest, pay attention to supplement foods rich in vitamin A, it is best to pay attention to the distance, often do eye exercises to ensure adequate sleep time.
3. What effect does watching too much computer have on people?
This generally has no effect, mainly because it is too focused. 1-Rest after 2 hours.
I sent this to others, and now I will copy it directly to you.
You can look at the bottom,
This can be cured, there is a way, it can be cured (including not affecting the birth of the child, etc.). ); Lose one's concentration, temper, etc. It is a precursor of obsessive-compulsive disorder, neurasthenia, anxiety, depression and schizophrenia. You can search online (what are obsessive-compulsive disorder, neurasthenia, anxiety, depression, schizophrenia and other mental diseases) and compare them:
I'll tell you a place.
See if there are any Wal-Mart or Carrefour supermarkets in your city, or supermarkets such as RT Mart, Yonghui, Lotus, CR Vanguard, Century Lianhua, Wu Mei, AEON, Auchan, Agriculture, Industry, Liansheng, Jiajiale, Yibaijia, spar, etc. These supermarkets are family-run supermarkets, which are self-produced and sold (that is, our own shampoos and soaps, such as Rejoice, toothpaste and other products, whether domestic or foreign. This one is not listed, but another one is listed, and our family holds a certain share of the shares of listed companies. To go shopping in the supermarket, you can bring your bank card and edible books (starting from 7000 yuan, divided into professional categories (according to the majors in the university; Classification of teaching materials), non-professional (novels, etc.). ), all kinds of languages), can quickly improve the performance (Life No.1 is also produced by this company, a box of 30 yuan is around, if you count it, 7,000 yuan /30 yuan = Life No.1, 200 boxes, one month 10 box of Life No.1, you can drink for about 20 months, and you can get the books you can eat quickly. This will not only improve memory, but also improve sleep and performance quickly. When you go to the supermarket, you can go directly to the manager of the supermarket (this is managed by your family, just like the brands of manufacturers and supermarkets, and this edible book is made by them). If you have a bank card and enough money, he will appear when you look for him. I tell you, there are three generations of drugs in the edible book, which can prevent and completely cure common mental problems (such as obsessive-compulsive disorder, neurasthenia, anxiety, depression, schizophrenia, adolescence (* * * will be addictive, and this can help you quit * * *). This medicine can help your brain to be normal and improve your natural performance. This kind of edible book is special. It is produced and sold by their own family, and it depends on the buyers. . . See if there is such a supermarket around you, please buy it nearby.
If you treat neurasthenia, anxiety, depression, schizophrenia, adolescence and other problems alone, you can go to the supermarket manager to buy drugs that can prevent and completely cure common mental problems (such as obsessive-compulsive disorder, neurasthenia, anxiety, depression, schizophrenia, adolescence and other problems). This is about a generation of RMB in 700 yuan (don't doubt this price, it's a fair price, just look at how many villages there are. Note: Drugs at this price are similar to hepatitis B vaccine and can be sold separately (if you have enough money, you will appear in front of them when you go to their supermarket).
If you are studying, you can choose to buy the book that you can eat instinctively, which can help you take the exam and test your professional title.
Note: If your illness is not common obsessive-compulsive disorder, neurasthenia, anxiety, depression, schizophrenia, etc. If you want to bring more money, take your parents' bank card to the supermarket I mentioned above and go directly to the manager of the supermarket. If it is not a common mental illness (such as corruption, etc. ), the price of this therapeutic lamp will start from RMB 10000 yuan. The starting price of drugs to prevent and treat mental problems and diseases is different (above what price, including edible books, other drugs unique to our family are given away free of charge).
Sometimes it's convenient to use at this time. Actually, they all belong to our family.
Go to our home for treatment early, and experience a good life and happy work early.
If the medicine you used to take had the same special packaging (that is, the shelf life of several years) as the medicine in ordinary pharmacies, it was all produced in our home (domestic/foreign). This is an emergency medicine (the term is strategic reserve).
Is there any way for people who play computer too much to keep healthy?
Washing your face after surfing the Internet can reduce radiation by 70%. Reminder: the biggest radiation of the computer is in the back. When the computer is not used on the screen, it is best to equip the monitor with a screen with better radiation protection effect. Pay attention to eat 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 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. 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 electromagnetic waves from being emitted again. 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 effect because of low brightness, which 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 best to stay half a meter away from the screen. After the computer is used, many particles of electromagnetic radiation will be adsorbed on the face. Washing your face with clean water in time will reduce radiation exposure by more than 70%. Cactus can attack bad people, and there is another advantage! It is said that putting a cactus in front of the computer desk can help reduce radiation. People who often use computers will feel uncomfortable with their eyes, their eyesight will drop, and they will get tired easily. People who often use computers should pay attention to the following aspects in their diet: eat some foods that are beneficial to their eyes, such as eggs, fish, cod liver oil, carrots, spinach, sweet potatoes, pumpkins, medlar, chrysanthemums, sesame seeds, radishes and animal livers. Eat more foods with high calcium content, such as bean products, bone soup, eggs, milk, lean meat and shrimp. Pay attention to vitamin supplementation: 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, citrus, jujube and so on. Eat some radiation-resistant food: although computers have little impact on human health, they should 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, 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 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. As long as you can see clearly, the distance should be at least 50 cm to 75 cm, which can reduce the harm of electromagnetic radiation. 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.

5. What effect does watching too much computer have on people's face?
Hello! Watching more computers can lead to dull skin, large pores, decreased vision and other symptoms. It is understood that the American Visual Research Association recently conducted a survey on computer operators, and the results showed that as many as 75% people suffered from "computer vision syndrome" in different degrees, which was manifested in four aspects: 1. Temporary myopia. After using the computer for a few minutes or hours, objects in the distance will be blurred. 2. Eye fatigue. I feel pain in my eyelids and forehead when operating the computer. 3. Look at the outline of the object is not clear, there are ghosts. Sometimes the image of an object remains in the eyes after the line of sight is diverted. 4. Dry eyes or tears. One of the most common "occupational diseases" of people who use computers for a long time is caused by the posture of operating computers. The main symptoms are sweating, neck and shoulder pain, and intermittent numbness in the scapula, shoulders and upper arms.
Satisfied, please adopt.
6. Watching the computer for a long time makes me sick. What should I do?
Don't look at the computer, go out for some air and look at the distance.
solution
1. It is best to turn your back to the window or sideways to avoid screen reflection;
2. The computer screen is lower than the eyes, that is, the eyes are slightly higher than the computer screen;
3. The computer screen is more than 60 cm away from the eyes, which is too close to cause eye fatigue and induce myopia;
4. The light in the computer operation room should not be too weak or too strong (12 square meter room can achieve the required illumination with a 40 watt fluorescent lamp);
5. Keep watching the computer for about 50 minutes, and rest for 10 minutes. You can rest with your eyes closed, and imagine seeing distant objects, or look straight into the distance. It is the key to prevent myopia. It will be better if you can cover your eyes. Relieve visual fatigue;
6. Blink more, keep your eyes moist, blink more than 20 times per minute, consciously control and get used to it;
7. Put a glass of water next to the computer to increase the surrounding humidity;
8. Don't rely on eye drops for a long time. It is ok to use them occasionally. After a long time, it will inhibit the secretion regulation function of the eye itself, resulting in dry eye.
9。 If you have already worn nearsighted glasses, it is recommended not to wear them when using your eyes at close range, such as watching a computer, or wearing a pair of glasses with low degree, which will help relieve eye fatigue.
7. What should I do if the computer sees too many eyes and is nearsighted?
Add a video screen, so that the light emitted by the display will be softer after being absorbed by the video screen.
But the quality of the video screen is also very important. Update the graphics driver to the latest version.
Set the refresh rate to 85HZ. Setting method: Right-click on the blank space of the desktop-Properties-Settings-Advanced-Adapter-List all modes-Choose from ordinary computers 1024x768 32-bit true color 85Hz. Always observe how computers protect your eyes. Do you often watch computer? Drink more chrysanthemum tea! ! Chrysanthemum tea is a good drink to protect your eyes! Chrysanthemum tea can eliminate eye edema and fatigue. If you drink too much water before going to bed, your eyes will swell like pandas when you get up the next morning. There is a folk method that can effectively relieve it, that is, apply the tea juice of cotton dipped in chrysanthemum tea around the eyes, which will soon eliminate this edema. Chrysanthemum is very effective in treating eye fatigue and blurred vision. China has known since ancient times that chrysanthemums can protect eye health. In addition to smearing eyes can eliminate edema, you can usually soak a cup of chrysanthemum tea to drink, which can eliminate the symptoms of eye fatigue. If you drink three or four cups of chrysanthemum tea every day, it will also help to restore your vision.
There are many kinds of chrysanthemums, and people who don't know the doorways will choose chrysanthemums with white flowers and big flowers. In fact, small, ugly and yellow chrysanthemums are the best choice.
In fact, chrysanthemum tea does not add tea, just soak dried chrysanthemums in water or boil them. Hot drinks in winter and iced drinks in summer are all good drinks. Juqi tea is a good eye protection drink! Lycium barbarum is added to chrysanthemum tea, both of which are Chinese herbal medicines for eye protection. The brewed tea is the famous "Chrysanthemum Qi Tea". In particular, students often get tired after reviewing their lessons on sunny nights. People with myopia often feel dry eyes. Drinking chrysanthemum tea often can improve their eye discomfort.
There is also a kind of cassia seed like black rice, which is boiled into tea juice and is also a good eye-care drink. Miso is stained with the material. Computer people should use you who often need to use computers at work, or you who often play computers. Please pay attention.
Do you touch the computer for at least six hours every day? Remember to drink at least one bowl of miso soup every day! Miso is fermented from soybean and rice and is rich in B 12, which is an important source of B 12 for vegetarians. Miso also contains a special enzyme that can excrete radiation. People who have received chemotherapy or used computers for a long time should eat them regularly.
In order not to destroy the enzyme of miso, it is best to add it before turning off the fire when cooking, which can replace salt and soy sauce. Mix a tablespoon of miso, lemon juice and molasses to make a delicious natural seasoning. It is most suitable for scalded vegetables such as okra, kale, bamboo shoots or broccoli.
Put a cup of hot water next to the computer. Do friends also have dry eyes and blurred vision? This is a common problem of many "computer families"! Internet addicts who like to stay up all night surfing the Internet do more harm to their eyes. Doctors suggest that people who often use computers should investigate the screen until their eyes are lower than the eye level 10 to 20 cm, which can reduce the chance of eyelid lifting. In addition to giving your eyes more rest, you should also blink frequently to moisten your eyes, because the average computer worker blinks 22 to 7 times a minute when focusing on the screen, which will make the tears on the surface of the eyeball unconsciously evaporate too much, so dry eye will be aggravated.
Put a cup of hot water next to the computer to increase the surrounding humidity to relieve eye discomfort. One more maintenance is one more health! Cactus, the bane of computer radiation, has another advantage besides attacking bad people! I heard that putting a cactus in front of the computer desk can help reduce radiation; Because cactus grows in a place with strong sunlight, its ability to absorb radiation is particularly good. Those computer students who are sedentary should find a cactus to protect their eyes.
As for how big you want, it depends on your needs! The brighter the computer light, the greater the damage to the eyes. The brighter the computer environment, the better. The doctor pointed out that when using the computer, the surrounding environment should not be too bright, and do not rely on the window to hit the computer, otherwise glare and reflection problems will easily occur, causing eye fatigue and soreness.
This kind of "computer vision syndrome" and wrist and back injuries caused by long-term use of computers have jumped to the first place among occupational diseases in the United States and must be paid attention to. You Zhihao, an ophthalmologist at Xiao Traditional Chinese Medicine Hospital in Taipei, suggested that the brightness of the surrounding environment should not exceed three times that of the screen. The office and home environment can be measured by photometer, and it is best to choose a direct light source on the head.
Generally speaking, when using a computer, it is better to turn up the "contrast" of the screen and turn down the "brightness" of the screen, which is unlikely to hurt your eyes. When choosing a computer screen, it is best to use a flat screen with high resolution (the screen is better to be recessed inward) and goggles; People who wear glasses should wear lenses with "anti-reflective coating" to prevent light reflection.
People who have been engaged in computer work for a long time may wish to have a pair of glasses dedicated to playing computer. People who use desktop computers will reduce 150 degrees, and those who use portable computers will reduce it by about 200 degrees, which can avoid the increase of myopia caused by long-term observation of close objects. Presbyopic users must wear multifocal glasses and expand the range of fancy distance to see more clearly.
As the saying goes, "prevention is more important than cure". Besides doing eye exercises to eliminate fatigue and eye relaxation, what other methods can prevent "computer vision syndrome"? 1. Proper eye rest: In natural state, pupils dilate, while pupils contract to indicate exertion. But if the light source is too strong, if you look at things at close range, your pupils will shrink and your eyes need to exert strength. Therefore, Dr. Zhang suggested taking a break of at least 5 minutes every 30 minutes while watching the computer. During the rest, you can roll your eyes or look at the distance. In short, you should stop staring at the computer so that your eyes can relax properly.
2. Suitable computer working environment: adjust the lighting to make your eyes comfortable, but because the computer itself is a luminous body, don't let the light source shine directly on the screen to avoid reflection. 3. Correct posture: keep your body and feet vertical. It is best to place the computer screen about 10 ~ 15cm below the eye level, that is, let your eyes look down at the computer.
For 14 inch screen, the distance between the screen and the eyes should be at least 60 cm, and for 15 inch screen, it should be 70 cm. 4. Wear appropriate glasses: dr. zhang thinks that having enough degrees is enough.
