Harm of computer virus and preventive measures

Are you a high-risk group for "computer sickness"? Computer disease "also called Video display terminal syndrome, is the use of computer time is too long, computer location is not scientific and computer space environment caused by a series of adverse reactions. Many respondents said that the use of computers is a necessary part of work, physical discomfort is difficult to avoid, and the survey data show that the company white-collar, it people, Media workers, such as long-term computer-related practitioners, has become a computer disease "high-risk groups."

"Computer disease", although not a life-threatening, but not to be underestimated. It can cause a chain of diseases in other parts of the body that affect the quality of work and life. At present, few people specifically to the hospital to see "computer disease", but the long-term use of computer damage caused by your attention!

What are the typical symptoms of "computer sickness"?

① Dry eye disease, visual fatigue: eye ache dry, blurred vision, vision loss.

② carpal tunnel syndrome: Palm numbness, wrist and forearm pain, swollen wrist joint weakness.

③ Neck and shoulder syndrome: neck and shoulder soreness, shoulder inflammation, lumbar spine pain.

④ computer dermatitis, skin blood disease: The power-on status of the display around will form an electrostatic field, absorbing air suspended dust, stimulating facial skin.

⑤ Central nervous disorder: headache, dizziness, insomnia, anorexia, nausea, low mood, slow thinking, forgetful, irritability, often feel tired.

⑥ Computer depression: Long time computer operation to form an "either or" mode of thinking, not accustomed to reach a compromise and understanding, loss of self-confidence, physical and mental exhaustion.

The harm of computer disease

The damage to the eye is not negligible. According to a World Health Organization statistic, a person watching a computer for a day lasts more than 4 hours, lasts more than 4 days a week, lasts a year, and 90% of people have varying degrees of visual fatigue syndrome. There are surveys that read paper books and operate computers at the same time, The latter appears to be 4-6 times more likely to see fatigue than the former. 3% of the people who use the computer have a cornea dot dye, and the computer 2-4 hours later will reach 60.3%.

In the normal state of the unconscious blink is 15-25 times per minute, but looking at the computer, due to focus on the screen, the physiological blink will be reduced to 5-10 times, coupled with the eyes of the computer when the eyelids open to increase the area of corneal exposure, tear evaporation will also accelerate.

Frequency blink careful is dry eye disease if the eye dryness, pain, photophobia, tears, foreign body sense and other symptoms, this is a typical dry eye disease, need to use artificial tears to moisten alleviate, the best time to hospital, lest cause corneal damage and chronic conjunctivitis and a series of ocular diseases.

In addition, to avoid a long time to watch the screen, every 40 minutes to rest for 5-10 minutes, look away, close your eyes, do a group of eye exercises, so that the muscles of the eye tension relief and relaxation.

Sedentary chair to become a spinal killer in addition to visual fatigue, dry eye disease, computer-induced another major hazard is the impact on the lumbar spine and cervical spine.

In the use of computers, the cervical spine most of the time in the buckling state, the long-term same posture easily lead to cervical degeneration. In addition to cervical spondylosis, the long-term use of computers for the harm of the lumbar spine can not be ignored.

When people lie flat or lying on their side, the force of lumbar intervertebral disc is relatively small; when standing, the stress of the lumbar spine increases, the force will increase further when standing forward flexion, and the force will be increased further when the seat is bent forward. And usually use the computer, most will use the posture of sitting forward flexion, which will make the lumbar intervertebral discs and other structures of the lumbar spine significantly higher pressure.

Adjust posture to save the disease spinal medicine experts introduced to ensure that the normal spine of the physiological flexion has a principle, called "neck pillow, back with, elbow braces, waist cushion." The height of the table and the height of the screen should be adjusted to ensure that the eyes can look at the screen. In addition, keep upright seat, avoid leaning side to ensure spinal balance.

Most of the pain is localized, there is no radiation pain, the pain can be adjusted by posture, exercise, physiotherapy, or use topical anti-inflammatory pain medication to alleviate.

Beware of "keyboard hand" and "Mouse Hand" "Mouse hand" study called carpal tunnel syndrome, long-term use of the mouse will cause carpal ligament hyperplasia, resulting in effective volume of wrist canal reduction, compression carpal tunnel nerves. "Keyboard Hand" is the sheath inflammation, long-term percussion keyboard, tendon in the tendon sheath constantly moving back and forth, wear tendons, long time will lead to tendinitis.

"Keyboard Hand", "mouse hand" patients often feel little finger even full hand pain and burning, even the hand muscle atrophy weak, the finger cannot separate, the ring finger and the little finger are chicken claw shape. This kind of injury is directly related to the posture of using the mouse keyboard, and it can not be cured immediately after injury, so it is necessary to make long-term adjustment, so we should take prevention as the most serious.

Do some "little tricks" in your spare-parts work. Rest is the most important means of treatment, when necessary, gypsum or low temperature plastic splint can be used to wrist, palm, finger fixed to straighten or functional position, local injection of drugs or physical therapy to eliminate inflammation, repair damage. But if the symptom is heavier, must not use the hyperthermia, The application of ice and other cold treatment methods, otherwise it will aggravate the symptoms.

For a variety of "computer disease", in the interview, many people also said that as long as the time allowed to take the initiative to adjust the rest.

Many people also give their own ease of "computer disease" tips:

① more stroll around, moving shoulders;

② change the posture with the mouse;

③ to do gymnastics, stretched stretched arms stretched legs son;

④ put the water cup far away, thirsty to walk a few steps to drink water, play the role of exercise.

PostScript language: With the popularization of computer and network, the traditional paper and pen record of the work of the way gradually replaced by computers, but in recent years, more and more computer families in the enjoyment of computer to bring high-speed and convenient at the same time, frequently encountered "computer disease" of the troubled.
