The designed desk and chair uses a special computer chair, which follows the "three right angles": the first right angle is formed under the computer desk in the west, the thigh and backup are the second instructions, and the arm forms the third right angle at the elbow joint. Lean your shoulder blades against the back of the chair, put your shoulders down and keep your chin away from your neck. Look straight at the center of the computer screen, preferably with a supported chair back and armrest, and the height can be adjusted. 2. The height of the computer should be appropriate. Install the center of the computer screen on the same horizontal line as the operator's chest. When using the computer, you should rest for 5- 10 minutes every hour and do soft exercises or local massage. 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, you should get up and move your limbs every hour of work, and do some actions such as clenching fists and pinching fingers to relax your fingers. When using the computer, the height of the keyboard and mouse on the computer desk should be lower than the elbow height when sitting, which is beneficial to reduce the damage to the tendon sheath of the wrist when operating the computer. 3. When using the mouse, don't suspend your arm to reduce the pressure on your wrist. When moving the mouse, don't use wrist strength, but try to rely on arm strength to reduce wrist gifts. Don't knock the keys of the keyboard and mouse too hard, and relax the force moderately. It is best to choose a mouse with a large arc and a wide contact surface, which is helpful for the dispersion of force. When using the mouse, use the "mouse wrist pad" to pad your wrist. Washing your face frequently can prevent the skin from being stimulated by radiation waves. Clean the office environment carefully. Because positive ions are firmly adsorbed on dust particles, the more dust there is, the more positive ions there are, and the greater the impact of computer radiation on human body. Drink more tea. Tea polyphenols and other active substances contained in tea help to absorb radioactive substances. 4. Drink green tea often. People talk about the most healthy drinks. Because it contains powerful antioxidants catechol and vitamin C, it can not only eliminate free radicals in the body, but also make the accessory renal cortex secrete hormones against stress, which greatly improves the mood. But it is best to drink it during the day, which will affect sleep. Most of the radiation emitted by the display does not come from its front, but from its sides and back. Therefore, don't point the back of the monitor at the back of your head or the side of your body. Placing a pot of plants or water under the computer desk can effectively absorb the electromagnetic waves released by the computer and reduce the adverse effects on human health.
Edit this paragraph to prevent
Improve the working environment 1. Low back health care: it is best to choose an office chair with backrest, oil pressure and roller design. This chair has a backrest. If the seat is too deep, a back pad can be added to support the back, so that the back can maintain normal curvature and reduce the pressure on the spine and muscles. The chair has an oil pressure design, which can adjust the height of the seat so that the feet can lie flat on the ground. The chair has a roller design, which can adjust the twisting angle of the body when sitting and reduce waist strain. 2. Mouse and keyboard: the height of the keyboard and mouse should be moderate, and the height of the keyboard is about 80 ~ 100 degrees when elbow is bent. The height of the mouse should be the same as that of the keyboard. For right-handed people, the mouse should be placed on the right side of the keyboard. Using keyboard and mouse for a long time is easy to induce tenosynovitis. At this time, you can add a wrist pad in front of the keyboard or use a towel to make a wrist pad, which can support the wrist and reduce the height of the wrist. The mouse position can also be padded with towels. 3. Computer screen: the screen should be adjusted to tilt upwards 15 degrees. When sitting, the first line of words on the screen will form a horizontal angle with the eyes. Don't face the window on the screen, at least make a 90-degree angle with the window to reduce the refraction of sunlight. A filter is added to the screen to reduce radiation and static electricity. In order to balance the line of sight with the screen and avoid frequent drooping of the head and repetitive movements of the neck, you can add a folder, but pay attention to the fact that the folder should be able to change its position at will to avoid muscle fatigue caused by twisting the head to one side for a long time. Setting up a computer does not mean that it is isolated from neck and shoulder pain. Bad habits of using computers can also bring pain. Develop good habits and stay away from pain: when using the computer, rest for 5 ~ 10 minutes every hour, do soft exercise or local massage, and at the same time develop regular exercise habits, and do stretching and muscle strength training for shoulders, neck and upper limbs to increase softness and muscle strength. 4. Relax the movement of neck and shoulder: When flying a kite, you can keep the muscle tension of cervical vertebra and spine, the elasticity of ligaments and the flexibility of spine joints, which is beneficial to enhance bone metabolism, enhance the compensatory function of cervical vertebra and spine, do not damage the vertebral body, and prevent the degeneration of vertebrae and ligaments. It is really a good prescription for preventing and treating cervical spondylosis left by our ancestors. Swimming: Because the head is always raised when swimming, the neck muscles and waist muscles are exercised, people do not have any burden in the water, and will not cause any damage to the intervertebral disc, which can be regarded as a relatively comfortable way of cervical spine exercise.
Edit this paragraph "Prevention and treatment of computer diseases"
At present, computers have become a necessity in the office. It is common for people to work overtime in front of computers, but all kinds of "computer diseases" also follow. For people who often use computers to work, medical experts introduced some methods to prevent diseases: 1, and pay attention to the combination of work and rest to prevent tendon strain. Operating the computer for a long time will cause pain in the knuckles, wrists, arm muscles, shoulders, neck and back. 2. Pay attention to eye hygiene. The distance between the eyes and the manuscript, the eyes and the screen should be kept above 50 cm, and it is best to use a 20-degree viewing angle in light. 3. Pregnant women should not be exposed to computers for more than 20 hours per week. To prevent pelvic congestion caused by sitting for a long time, we should pay attention to the coordination between the computer and the sitting position of the chair, so as to make the fetus develop healthily. 4. Long-term computer operators should eat more fresh vegetables and fruits and increase the intake of vitamins A, B 1, C and E ... 5. Make some green tea every day. Lipopolysaccharides in tea can improve the hematopoietic function of the body. Injecting lipopolysaccharide into human body can enhance the nonspecific immunity of human body in a short time. Tea can also prevent radiation damage. 6, in order to avoid the screen reflection or unclear, the computer should not be placed on the opposite or back of the window; Ambient lighting should be soft. If there is a window behind the operator, the curtain should be closed to avoid bright light directly shining on the screen, reflecting bright images and causing eye fatigue. 7. The computer room should be ventilated frequently, and ventilation fans or air conditioners should be installed indoors to reduce the impact of bromine on the body. The dust density of computer accessories is hundreds of times higher than that of other spaces in the computer room. They are attached to human skin for a long time, which will lead to various skin diseases. The computer room should be kept clean and sanitary, and the computer should be scrubbed regularly. [ 1]

Edit the tips for this paragraph.
Tip 1: the environment should be comfortable.
Before using the computer, we must first find a suitable location and surrounding environment for the computer. This is the first step and the most basic preparation for long-term work. It should be mentioned here that the adjustment of light is very important. Indoor light should be soft and the brightness should be similar to that of the screen. Don't operate the computer in too dark or too bright environment, because black and white contrast is harmful to your eyes. 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.
Tip 2: Express scientifically.
Put it scientifically. In order to adapt to the normal diopter of human eyes, the screen position of the display should be below the line of sight 10-20 degrees, and the distance from people should be 0.6-0.7 meters. The space behind the display should be as large as possible so that the user's eyes can rest off the screen.
Tip 3: Sit up straight.
Comfortable seats are also a guarantee for healthy use of computers. The height and inclination angle of the seat should be adjusted according to different people. You know, according to experts, incorrect sitting posture is the chief culprit that causes white-collar workers to suffer from wrist, neck and lumbar diseases frequently. It is very important to maintain a correct sitting posture when using a computer. Let's take a look at the standard sitting posture: sit up straight, the upper arm is naturally straight, the forearm is perpendicular to the upper arm or slightly upward 10-20 degrees, the wrist is flush with the forearm, the shoulder blade rests on the back of the chair, the shoulder is put down, and the chin is not close to the neck. The thighs should be flush with the chair surface, and the calves should be at 90 degrees with the thighs. Don't cross your legs
Tip 4: Get used to it.
To develop good operating habits, the position of the keyboard and the position of the monitor should be coordinated with the sitting posture, and the posture should be correct when operating, and you should not bend over to operate or stick to the computer. Be careful not to let your eyes get too close to the screen. Some people who don't wear glasses at ordinary times should also consider using corrective glasses at work after consulting a doctor.
Tip5: Rest in time.
When using the computer for a long time, you should ensure proper rest. Generally speaking, after using the computer for one hour, it takes about 15 minutes to rest. Don't use the computer continuously for more than four hours. When resting, it's best to do some activities, such as walking, abdomen and chest, wrist shaking and so on. Eye protection can do eye exercises or look at the distance. Or you can take a few deep breaths in place, or turn your shoulders and move your waist. A few simple and light tricks can rejuvenate you and keep working hard.
Edit this paragraph and use the computer healthily.
Now, almost all office workers use computers at work. After working in front of the computer all day, many people will feel pain here or there at night, or cause some diseases. Russian clinical medical experts put forward many effective suggestions on how to arrange the work in front of the computer reasonably and avoid health problems. ◆ 1. Working in front of the computer is a sitting lifestyle, which means that the muscles are not exercised at work. This sitting lifestyle is most likely to lead to neck and back injuries. If office workers don't arrange their work properly, the situation will be even worse. It is very important that office workers should install adjustable monitors. This kind of display can be adjusted to suit everyone's different physiological characteristics. It can also rotate in any direction, and its height and curvature of the display can be adjusted at will. ◆2. If the monitor is slightly to the left, the left neck muscles will be tight, while the right muscles will be stretched. This imbalance will lead to the right deviation of the head. Therefore, the computer monitors in the office must be placed according to the center line. In other words, the monitor must be placed directly behind the keyboard, because the midline of the keyboard must be consistent with the midline of the monitor and the human body. ◆3. It is also very important that the monitor should not be installed too high or too low. The starting line on the monitor must be on the same level as your eyes. If the user must always look at the paper on the keyboard or desk, the starting line of the display should be lowered. ◆4. To check whether the monitor is installed correctly, you only need to do a simple test. Remember the points on the monitor that you should look at frequently, and then close your eyes. Do some head movements up and down slowly. When your head moves to a comfortable position, stop and open your eyes. If the monitor is installed correctly, your eyes will be fixed on the point you wrote down before. ◆5. The paper used in work must be placed at the same distance, height and angle as the computer monitor. To do this, you can use a stand, but the stand must be fixed near the monitor and at the same level as your eyes. If you want to type the whole article on paper on the computer, put the paper in the right position in front of you, or put it on the bench between the monitor and the keyboard, this method will bring you a lot of convenience. ◆6. Usually, at work, you must frequently look at the monitor first, then at the keyboard, and then back to the monitor. Repeatedly, at the end of the day, you will feel a terrible pain in your neck. In order to avoid this situation, you can install a keyboard that suits you. Recently, many new models about information output and input have been patented worldwide. Among them, there is a vertical keyboard and a conical keyboard beside the display, and the keys on the keyboard are all designed vertically. Even without these technological innovations, everyone who uses computers can find a way to avoid this situation. The keyboard is placed at an angle that the front end is lower than the back end. Moreover, the keyboard must be lower than the user's elbow, so the elbow folding angle must be 90 degrees or slightly larger. Teach you a few tricks to use the computer healthily. For people who use computers, experts have listed the following five points for attention: ◇ 1. Don't put the monitor too low, keep it in a horizontal line with your eyes. ◇2. Don't lower your elbow than the desktop. ◇3. Don't put the keyboard too far away from your hands. It is important to keep elbows and shoulders level. ◇4. The seat should not be too low and cannot be pressed below the knee. People who use computers should not bend their knees and put their feet under the seat. It's best to put your whole foot flat on the ground. There are many conditions that can help to avoid the pain and illness caused by using computers. One of the most important conditions is that users should rest as much as possible during the day's work. Here are some simple suggestions to take a break at work. For example, put your mobile phone on a nearby table at a distance from you, and you can stand up and move when you need to answer the phone; Move the printer away from the desk, and you can also stand up and move when you need to take the printed materials; You can also put the folder away from the computer; When you have to restart your computer, you can also leave your seat and have a rest. Also, every 45 minutes, do some simple neck exercises: stretch your neck forward, then turn your head left and right, and then bow your head left and right several times. If you arrange your work reasonably, you will have a chance to rest and exercise at work, so that you won't feel so tired at the end of the day. [2]
