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 for 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.
