In addition, if the male driver is sedentary for a long time, the space is closed and the temperature is high, it will affect the fertility and reproductive ability, and it will also cause urinary system diseases because it is inconvenient to hold the urine for a long time. ...
The Fourth Affiliated Hospital of Harbin Medical University recently conducted a physical examination on more than 0/000 taxi drivers in Harbin, and found that nearly 60% of them suffered from different degrees of lumbar muscle strain, scapulohumeral periarthritis, stomach complicated with lung complicated with nephropathy, or were in sub-health state. This is the population with the worst health status among the professional population in this hospital in recent years.
The manifestations and causes of computer occupational diseases in this paragraph are edited and arranged. Computer workers often ignore computer occupational diseases in their work. This kind of "repeated tension injury" is mainly manifested as functional injuries of eyes, hands and wrists.
First, my eyes feel tired and uncomfortable. The main reason is that computer workers are prone to visual fatigue due to factors such as long-term focus on the screen, constant brightness of the computer screen, dense handwriting and inappropriate indoor lighting. In addition, we don't pay attention to adjusting our vision at work, which leads to eye fatigue and decreased vision.
The second is the functional injury of hands, wrists and arms. Because computer operators have been engaged in data input and keyboard printing for a long time, repeated single actions need considerable static support because of small amplitude change, which makes some neuromuscular tissues nervous. If the wrist is tense for a long time, it will cause tendon inflammation and pain in the hand, wrist, arm and even shoulder, and sometimes it may involve tendon sheath and muscle tissue.
Third, indoor environmental pollution endangers the health of computer workers.
Edit this paragraph 1, affected parts and symptoms of neck and back.
There is often noise when the neck rotates, which is easy to "stiff neck".
I feel a lump and tenderness.
There is a tingling sensation locally.
In severe cases, there will be nerve compression such as headache, blurred vision, decreased attention, paralysis and pain of upper limbs.
2, tenosynovitis
Using the keyboard or moving the mouse for a long time, fingers keep sliding or typing on the keyboard, which leads to repeated actions and friction for a long time, causing tendon sheath thickening and inflammation. This is tenosynovitis. The finger disc is compressed by the thickened tendon sheath, which causes severe pain and local swelling during activity.
3. Carpal tunnel syndrome
The design of the keyboard often allows users to lift their wrists up before use, but this will narrow the carpal tunnel. If it lasts for a long time, the flexor tendon of the hand keeps sliding in the carpal tunnel, which will easily cause carpal tunnel syndrome, compress the nerve lines and blood vessels of the hand, and lead to paralysis of the hand and even muscle atrophy.
4. Lower limbs
Most civil servants sit in office, but if they sit for too long, and the space under the table is too narrow, it is difficult to straighten their legs, which leads to blood circulation in lower limbs and paralysis of their feet. However, long-term overlapping of feet will lead to fatigue and strain of intervertebral disc ligament.
Edit this paragraph 1 to improve computer occupational diseases. Sit upright. Now it's not the computer itself that causes the problem, but the way we are used to sitting. How we sit depends entirely on ourselves. Office workers should beware of sedentary lifestyle disorder.
We can sit on a low chair or a square stool with no backrest, arms high and head low, and cross our legs under the table with difficulty. Working in this position for an hour will make you have a headache, backache, numbness in your neck and shoulders and inflexible arms. You can get double chins and stiff cervical joints by sitting for one to one and a half years. If the elbow is often lower than the wrist, and the hand is held high, the nerves and tendons are often compressed, the hand will begin to numb, the fingers will lose flexibility, and joint pain will often occur. There is another complication of incorrect posture-"occupational spasm". 100 years ago, the clerks of law firms got this disease after long-term copying-because of nervousness, their right hands would have severe pain when they started to finger. Now this disease often patronizes people whose wrists are lower than their hands and keep banging on the keyboard. Pain makes people restless, and musculoskeletal disorders have long plagued office workers, so be alert to "poor excretion"
The best way to solve the above problems is to buy a special computer chair and sit on it and follow the "three right angles": the first right angle is formed at the knee under the computer desk, the second right angle is formed between the thigh and the back, and the third right angle is formed at the elbow. shoulder pad
We should pay enough attention to the prevention of lumbar spondylosis and cervical spondylosis from an early age and maintain good living habits. You should choose a suitable posture for work and study, especially young white-collar workers, car owners and people who have been engaged in paperwork for a long time. Try to move as much as possible, walk more, climb stairs, stand up regularly to do exercises, exercise limbs, cervical vertebrae and waist, and develop good health care habits. Lean back, put down your shoulders and keep your chin away from your neck.

2. Do a local massage at rest, starting from the fingertips and massaging all the way to the forearm. Raise your tired arm and shake your fingers from time to time to help venous blood return better. Women with PMS and those who are prone to spasms should not fasten their belts and sit in front of the computer in tight jeans-this can easily lead to severe abdominal pain. Other women had better loosen the tight belt on their trousers or skirts from time to time.
3. Pay attention to the problem of electromagnetic radiation at work mainly on the display. However, unlike what you think, like the nuclear radiation emitted by the atomic bomb explosion, the electrified display has no nuclear radiation. But when the monitor is working, there will be quite a lot of electromagnetic radiation, which will ionize the air: we are surrounded by positive charges (positive ions), so don't confuse them with negative charges formed on the beach or on the mountain after a storm.
The more beneficial the negative charge is, the more harmful the positive charge is-they enter the lungs through breathing and then are transported to various tissues of the human body with blood circulation, thus changing the charge of cells. Therefore, we will suffer from insomnia, nervousness, irritability, increased palpitations and decreased immunity.
In fact, the harm caused by electromagnetic radiation is far more than that: high electromagnetic radiation affects health. Experts said that four types of people should be careful about girls suffering from Parkinson's disease, which is suspected to be related to environmental pollution. Electromagnetic radiation from household appliances is an important cause of asthma in children.
In addition to electromagnetic radiation, there will be electrostatic field around the turned-on display, which will almost suck the dust of the whole room into its own field. Sitting in front of the computer, breathing air containing dust particles makes the mucosa dry and easy to cause allergies. Therefore, you may have a stuffy nose, an itchy throat, and even dermatitis-erythema and rash from time to time.
It is impossible to completely avoid electromagnetic radiation, but it is very simple to weaken its harmful effects-when using the monitors produced after 1996, the office environment should be carefully cleaned, because positive ions will be firmly adsorbed on dust particles. Don't pile up mountains of papers and documents around the computer, put all the necessary documents in the cupboard in different categories. Wipe the surface of the computer desk with a wet cloth dipped in antistatic agent. Always open the window for ventilation.
Don't forget to put some moisturizing cream on your face before going to work. It's best to prevent nervousness. At night, soak the towel with chamomile extract (a simpler method is to use a wet chamomile tea bag) and apply it directly to the forehead and cheeks.
4. Learn to rest. All women who work in front of the computer should rest their eyes for 2-3 minutes every half hour and do 10 minutes of exercise in other parts every hour. However, it is impossible to "rest" so often when the work is tense. What should you do?
Let our muscles rest and relax for 2-3 minutes. Therefore, you should always change your sitting posture, lean back in the chair, tilt your head back and look at the ceiling, stretching beautifully.
Learn to turn your eyes from the computer screen to the window when thinking. In some offices, there are fish tanks for this purpose: watching water and fish will relax you without affecting your concentration. If you can have more than 20 minutes' rest every two hours, I suggest you take a walk outside your workplace.
5. Keep your distance. The picture on the monitor is dazzling and keeps flashing. When we look at the monitor, we stare 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, inflamed and painful. After working in front of the computer for four hours, almost everyone's eyes will feel sore and trachoma.
If you are close to the monitor, sometimes your eyesight will decline: your eyes are used to focusing on the tip of your nose, so you won't relax for a long time. Sometimes after working face-to-face with the "computer" for a few hours, your eyes begin to get bigger and it is difficult to see the objects outside the computer desk.
In order to avoid your vision damage, the distance between the monitor and the face needs to be 70-80 cm, slightly lower than the line of sight of the eyes. 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.
Don't ignore the harm of the monitor to your body. The monitor is ruining your beauty.
You can't display images of your face, lights and bright objects on the screen (all light and shadow will double your eyes). If you wear glasses, give yourself a pair of lenses with anti-reflective coating. In order to prevent conjunctival dryness, we can drop some drops with the same composition as our tears in the morning. You can apply a few minutes of wet wipes cooked with light black tea at night, which will quickly eliminate congestion and fatigue.
