When we sit in front of the computer for a long time, we need to get up and look far away to help us relieve visual fatigue.
3. When we are worried about our eyesight, we can help us protect our glasses through eye exercises, which should be done by most people.
4. If you don't have a plan to use the computer healthily, you can open Tencent Computer Manager and find the toolbox page.
5. Click to enter the health assistant function page, you can turn on the eye protection color matching function to protect our eyes when using the computer.
6. After opening, when we open WORD or other documents, there will be a very mixed background color.
How to use the computer 2 1 healthily and adjust the screen color;
Desktop-Right-Click-Properties-Appearance-Advanced-Item Selection (Window), Color 1(L) Select (Other) to change the color tone to: 85. Saturation: 123. Brightness: 205-"Add to custom color-"Confirm at the selected point of custom color-"Ensure that all documents are no longer dazzling with black words on white background, but very soft red bean paste green.
2, adjust the brightness of the display:
The brightness of the display is too dim, and the pupils are dilated, which is easy to cause eye fatigue. The brightness level of the display should be 3~4 times of the lighting brightness of the whole room. Secondly, the characters on the display should look clear and stable, and it is advisable to minimize flicker by adjusting the refresh frequency of the computer display.
In addition, it is necessary to adjust the bright contrast of handwriting, and the words on the fluorescent screen are 5~ 10 times brighter than the background color. Don't always use the same background color, because staring at the same color for a long time can also cause visual fatigue.
3, indoor lighting light should not be directly reflected to the screen, the brightness is darker than usual.
4. Place the document to be read at the same height and distance as the fluorescent screen, and don't move the focal length between two objects too frequently.
5. Blink at least once every one or two minutes 1 time. Every hour you work in front of the monitor, you should rest 10~ 15 minutes. Rest refers to looking at objects 6 meters away, especially those moving in the distance.
6. Some brightly colored fruits, such as oranges and carrots, and foods rich in vitamins and protein, such as lean meat and milk, are all helpful to the renewal of retinal pigment.
7. Place the computer 50~75 cm ahead, parallel to the eyes, and down about 30 degrees, so as to ensure that both feet touch the ground. If you use your laptop for a long time, you can add an extra mouse, keyboard and tiltable shelf so that you won't get tired of browsing the screen.
4. Keep a healthy distance from the computer screen. At least 50 cm in front of the computer screen, the screen height is slightly lower than the eye height. Don't point the screen at the window to avoid reflection.
5. Always ignore and blink. In order to prevent eye dryness and fatigue, the focal length of eyes should be changed frequently. Looking at the distance or blinking often helps to keep your eyes moist.
6. Keep office supplies such as keyboards clean. Office equipment such as keyboards and telephones are prone to bacteria. There are even more bacteria hidden in the desk than in the toilet seat. Sitting near it for a long time will hurt the respiratory tract.
7. Clear up the messy table. Too much clutter on the desk can make people lose their temper easily.
8. Breathing exercises. Take a deep breath. When the abdomen bulges, hold your breath for 3 seconds and then exhale, which can relieve fatigue.
9. Put some photos of your family. Putting photos of family or friends, a bonsai, favorite posters, oil paintings and souvenirs that bring happy memories can relax your mood.
How to use computers healthily? A remarkable sign of the information age is that computers have been closely linked with our lives. But we are praising it. At the same time, the computer is also gently hurting your health and my health, and computer syndrome is quietly coming into our lives.
Computer syndrome is muscle fatigue caused by people's long-term posture inseparable from computers and the damage of electromagnetic fields and various light radiation to the body, which leads to the disorder of the central nervous system and the decline of immunity, causing headaches, insomnia, palpitations, excessive sweating, anorexia, nausea, depression, mental retardation, irritability and frequent fatigue. Lesbians may also have irregular menstruation. Such as cervical spondylosis, scapulohumeral periarthritis, backache and stiff arm muscles.
Experts point out that if a child is obsessed with computers from the age of 8, 10 years later will become a computer syndrome patient.
Modern medical theory holds that massage can regulate the inhibition and excitement of the central nervous system, thus achieving the effect of analgesia and sedation. Massage can also improve microcirculation disturbance, increase CO2 excretion of tired muscles, and accelerate blood and lymphatic circulation. Regulate the function of the five internal organs, make nutrition, health and qi and blood flourish; Make people refreshed and happy, and relieve psychological and physical fatigue caused by psychological tension; Relieve symptoms such as cervical spondylosis, scapulohumeral periarthritis and low back pain, and make people conscious and energetic.
Therefore, when we enjoy the convenience brought by computers, we must do a good job in self-psychological adjustment, strengthen our awareness of self-psychological health care, and take necessary preventive measures. In addition, don't forget to use massage therapy to protect yourself from the adverse effects of computers on your body.
With the popularization of computer application, some people began to go to the hospital for treatment because of visual fatigue, dry eyes and decreased vision. How to relieve visual fatigue? Experts remind that exercise is the best way to relieve visual fatigue.
Sun He, a professor at the School of Clinical Medicine of Heilongjiang University of Traditional Chinese Medicine, said that sitting at a desk for a long time, working at close range and overusing the eye's adjustment ability will aggravate visual fatigue. Long-term eye users should attach great importance to eye care. The best way to relieve visual fatigue is to exercise, do eye exercises, overlook and drop anti-fatigue eye drops.
According to Professor Sun He, when you feel dizzy, gently close your eyes, do eye exercises, and then look far away for a while, and your visual fatigue will be relieved immediately. It is more ideal to do outdoor sports if conditions permit.
In addition, it is also very useful to ask doctors to choose eye protection points for ear pressure in hospitals. When you are tired from work, it is also useful to close your eyes and press the ear points. Moreover, in traditional Chinese medicine, drugs that tonify liver and kidney, clear liver and improve eyesight also have the effect of resisting visual fatigue.
The survey shows that journalists, editors, network designers, typists and white-collar workers are the high-risk groups of "computer diseases"
In modern society, computer has become an indispensable tool in people's life and work, but it has also become a "double-edged sword" more and more: it brings convenience and speed to people's life and work, but it also quietly harms people's health, causing people's vision decline, joint injury, radiation injury and head and shoulder pain. According to the survey, 83% of the people who often use computers feel eye fatigue, 63.9% suffer from shoulder pain and low back pain, 56. 1% and 54.4% suffer from headache and loss of appetite, as well as autonomic nervous disorder, depression and arteriosclerosis psychosis.
■ Excessive use of computers can easily lead to "computer disease"
Zhang Xinli, director and chief physician of the special needs clinic of the 302 Hospital of the People's Liberation Army, told reporters that many people who use computers excessively are prone to this kind of "computer disease".
Director Zhang said that if you don't pay attention to using the computer for a long time, your eyes are the most vulnerable, your eyesight is not good, your eyes are dry and jealous. Secondly, skin diseases are caused by static electricity generated by computers. Static electricity will absorb a lot of suspended dust, stimulate facial skin and cause allergic skin rash. At the same time, dealing with the computer keyboard for a long time, typing or moving the mouse repeatedly on the keyboard every day, the wrist joint is long-term, dense, repeated and excessive, and gradually forms wrist joint injury, which is easy to get wrist joint syndrome, commonly known as "mouse hand", which is characterized by pain and numbness of the index finger or middle finger and muscle weakness of the thumb, which may lead to nerve injury and muscle atrophy of the hand. Moreover, women are more likely to get it than men, because women's wrists are smaller than men's, and the median nerve of the wrist is more vulnerable to oppression.
In addition, sitting in front of the computer for a long time, if the sitting posture is incorrect, is prone to neck, shoulder, back pain, computer bow syndrome, computer dizziness and so on. However, computers are more harmful to human beings, such as multiple personality disorders, psychopathy and brain advanced cognitive dysfunction, and can also show some so-called psychosomatic diseases with both physiological and psychological characteristics, such as gastrointestinal dyspepsia, autonomic nervous dysfunction and obesity.
Director Zhang introduced that journalists, editors, network designers, typists and white-collar workers who stay in the company all day and use computers as their main tools belong to the high-risk group of "computer disease", mainly because their work cannot be separated from computers. In addition, some women and children, especially teenagers addicted to internet cafes, are also high-risk groups of computer diseases, because their resistance is relatively low, and they are more likely to get computer diseases when facing computers for a long time, which is very unfavorable for their healthy growth.
■ Long-term use of computers requires health protection.
Director Zhang pointed out that the emergence of "computer disease" is mainly related to people's sitting posture in front of the computer, the way they use it and the length of time they use it. Therefore, for people who use computers for a long time, it is very important to do a good job of protection.
First, sit correctly. When operating the computer, try to keep a natural sitting posture, with your back straight and your neck straight. The shoulders droop naturally, the upper arms cling to the body, and the elbows bend 90 degrees. Operate the keyboard or mouse to keep the wrist as horizontal as possible.
Second, the height of the computer should be appropriate. Install the center of the computer screen at the same height as the operator's chest, and it is best to use a chair with adjustable height. There should be enough space to stretch your feet, your knees naturally bend 90 degrees, and your feet will not leave the ground. Don't cross your feet to avoid affecting blood circulation.
Third, keep a proper distance from the screen. The distance between the eyes and the computer screen should be 40-50 cm, so that the eyes can look down at the screen horizontally or slightly, which can relax the neck muscles and minimize the area of the eyeball exposed to the air.
Fourth, the combination of work and rest. Avoid operating the computer continuously for a long time. You'd better have a rest after using the computer for 30 minutes. You can take a walk outdoors, or look up at the sky, or overlook it, or do 10 to 20 neck stretching and chest expanding exercises.
Five, keep the skin clean. There is a lot of static electricity on the surface of computer screen, and the accumulated dust will be transferred to the exposed skin of face and hands. After a long time, it is easy to cause macula and pigmentation, and even cause skin lesions in severe cases. In order to reduce radiation, the office should be kept ventilated and dry, so that those harmful substances can be discharged as soon as possible. Putting a pot of water or a pot of flowers under the computer desk can also reduce radiation, and washing your face frequently can also prevent your skin from being stimulated by radiation waves.
Sixth, a reasonable diet. Usually eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat and other foods, and eat less greasy, sweet and spicy foods to supplement vitamin A and protein in the human body. You can drink more tea at ordinary times. Tea contains active substances such as tea polyphenols, which is beneficial to absorb and resist radioactive substances.
Finally, don't forget to wash your hands after using the computer. There are many bacteria and viruses attached to the keyboard, which can also bring harm to people.
The best place to use the computer healthily is to place the center of the fluorescent screen about 20 degrees below the horizontal line of sight, and the distance from the eyes should be 36-4 1 cm, not too close.
In order to avoid the reflection and unclear of the fluorescent screen, the computer should not be placed on the opposite or back of the window, and try to avoid or reduce the dazzling light on the fluorescent screen.
Don't operate the computer in the dark, because the contrast between black and white is harmful to your eyes.
The place to sit should be as comfortable as possible. If possible, try to use an adjustable armchair.
People who wear glasses should have a pair of glasses to use in front of the computer. If it is bifocal glasses, it is necessary to change it into a zoom lens, so as to ensure that the contents displayed on the screen can be seen clearly at different distances.
Develop good operating habits. The position of the keyboard and the position of the monitor should be coordinated with the sitting posture. When operating, the posture should be correct, and you should not bend over or operate near the computer.
You should relax your eyes after using the computer for about an hour. You shouldn't use the computer for a long time. It's best to prepare some eye care drugs when your eyes are uncomfortable.
When using the computer, don't turn it on and off frequently, which will damage the computer's monitor, hard disk and other equipment and affect its service life. Usually turn it off for 30 seconds before turning it on.
Put the computer in a safe place, not in a place where it is easy to bump, especially the hard disk. Pay attention to moistureproof, antistatic, anti-collision and shockproof.
Pay attention to the maintenance of the computer after using it for a period of time. If you know the hardware, you can open the chassis for internal maintenance.
Nowadays, CD-ROM drive has become a kind of "consumable". Therefore, apart from installing software, it is rarely used to watch VCD, because the format and software of VCD are different, and many of them are poor quality pirated. Long-term use of this disk will greatly affect the service life of the CD-ROM drive.
How to use computers healthily With the progress of science and technology, computers have provided us with a lot of convenience in our work and life. For office workers, they have to be accompanied by computers every day, and sometimes they use computers for more than ten hours a day.
Although computers can greatly improve the work efficiency of office workers, long-term use of computers will also bring great harm to the health of office workers. So how should office workers use computers healthily?
First, put a pot of plants next to the computer
The biggest harm of computer to human body is radiation. Office workers use computers for a long time every day, and their health will be hurt by long-term computer radiation. Although it will be normal for the time being, after a long time, the radiation of the computer will accumulate day by day, and the harm will become more and more serious.
Many office workers will put a pot of plants next to the computer, because one of the characteristics of plants is that they can absorb the radiation of the computer, so that the radiation damage of the computer will be greatly reduced when facing the computer for a long time.
Put a pot of cactus or green radish next to the computer, which can absorb the radiation of the computer. These plants also have the benefit of relieving visual fatigue.
Second, try to use laptops.
For office workers, considering the composition factors, the computers used in office are basically desktops, which are not only troublesome to assemble, but also have great radiation.
Therefore, office workers might as well use laptops instead of desktops, because the research found that the radiation of laptops is much smaller than that of desktops, and the use of laptops can effectively control the radiation of computers.
Moreover, everyone who knows computers knows that the current notebook computer runs at the same speed as a desktop computer, which is very convenient to carry and use and will not affect the daily office of office workers.
However, it should be noted here that using a laptop is just like using a mobile phone, that is, charging the laptop before unplugging it, because if the laptop is plugged in, the electrified transformer is the main source of computer radiation, which is why the desktop computer radiates so much.
Therefore, when the laptop is unplugged for use, its radiation will be further reduced.
Third, often wipe the computer screen.
For office workers who love cleanliness, they will wipe the computer screen every day, because the electrostatic effect of the computer screen will absorb a lot of dust and affect the beauty of the computer screen.
But what they didn't expect was that wiping the computer screen often is also a good way to reduce radiation, because the dust adsorbed on the computer screen will increase the radiation of the computer, and wiping off these dust will reduce the radiation emitted by the computer, thus reducing the harm of computer radiation to the human body.
Fourth, turn down the brightness of the computer screen.
The transformer mentioned above is the main source of computer radiation, and the desktop must be plugged in before it can be used, which is also the reason for the large radiation of the desktop.
In addition, the brightness of the computer screen is actually a radiation source. The brighter the computer screen, the greater the radiation, so office workers can lower the brightness of the computer screen when using the computer, which can not only reduce the radiation hazard, but also protect their eyes, killing two birds with one stone.
If you don't use the computer, you can turn it off or stand by, or turn off the computer monitor, which can also effectively reduce computer radiation.
Five, often stand up and exercise.
Office workers usually sit there when using computers. After using the computer for a long time, their eyes will be very sour, because staring at the computer screen for a long time will make them tired and uncomfortable. More importantly, sitting and using computers for a long time is also very harmful to their health.
Sitting in front of the computer for a long time without exercise will not only affect the blood circulation and lymphatic circulation of the whole body, but also slow down metabolism, accumulate metabolic waste in the body, make the lower body stout, aggravate the symptoms of eye discomfort and make the brain tired.
Therefore, office workers must often get up and exercise for a period of time. They can stretch themselves in activities, which not only can exercise their muscles and bones, but also can rest the whole body, relieve the fatigue of the brain and eyes, and is also very helpful to improve work efficiency.
6. Wash your face every once in a while
To say that our body is closest to the computer is the face, because when using the computer, our eyes are always staring at the computer screen, and our face is always affected by computer radiation, so many office workers always complain that their skin is getting worse and worse, which is actually the influence of computer radiation.
The radiation of the computer will make the dust particles around the computer gather together and block the facial pores. In order to breathe, the skin will make the pores bigger and bigger, which will make the facial skin more and more rough and the skin quality will be greatly reduced.
Therefore, after using the computer for a period of time, you should wash your face and clean your skin, and also let your brain and eyes rest and relax.
