Keyboard hand, mouse hand, glaucoma, spinal disease... These rampant urban diseases are computer diseases! But they are trivial problems that don't attract your attention. Let me introduce these common computer diseases to you, so that users can know them and take preventive measures.
Let's take a case to show you:
These days, the news of "cervical vertebra deformation caused by 8-year-old boy's addiction to iPad" has spread wildly on the Internet, which has aroused the concern of parents. Aunt Bao learned from many hospitals in Zhengzhou that in recent years, more and more children with cervical spondylosis are getting younger and younger, and bowing their heads for a long time is the "culprit".
Children with cervical spondylosis are getting younger and younger
"8-year-old boy's cervical spine deformation caused by iPad addiction" sounds scary. Is this an example or a common phenomenon?
Let's take a look at this 8-year-old boy army first. According to Junjun's mother, Junjun began to play tablet computers at the age of 4, playing for two hours every day.
The attending doctor of the army concluded that the cervical vertebra had been strained at ordinary times, and the most recent time was too long. During the film examination, it was found that the cervical vertebra had been deformed.
Deputy director of neck, shoulder, waist and leg pain department of Luoyang bone setting hospital, Henan Province__ Qiang introduced that clinically, patients like the army are very common. They have to receive 200 or 300 cases a year, and they are getting younger and younger.
__ Qiang received a 10-year-old boy and said that he had neck pain, headache and vomit when he ate. "He is thin and small, and his height and weight are lower than his peers. After investigation, there was a problem with the child's cervical spine." As soon as I asked, I learned that the child's parents were busy with work and often locked him at home. "It was the child's long bow that caused cervical strain, and the parents didn't correct it in time."
Children's cervical spine problems affect their long body
__ Qiang treated the boy. Before long, the child could eat more, and the symptoms of headache and neck pain were relieved. A year later, when he treated the child again, the child was much taller than before.
"Cervical spine is very important for children's growth and development. I hope parents will pay more attention." He warned, "children in growth and development are still growing, and their bones are very fragile, which makes them more likely to have problems."
__ Qiang said that if there is a problem with the cervical spine, it will affect the whole body.
How to prevent the doctor to teach you
Summer vacation is coming, and it's time for children to have fun.
__ Qiang reminded parents that they must correct their children's bad sitting posture and habits. In principle, get up and move their cervical spine every half an hour.
Don't cross your head for too long, but hold your head back slowly, but you can improve the stability of each other. "Some children will have neck discomfort and keep turning their heads, so parents have to take their children to see a doctor as soon as possible."__ Qiang said.
Are you a high-risk group of "computer disease"?
"Computer disease", also known as video display terminal syndrome, is a series of adverse reactions caused by using the computer for too long, unscientific placement of the computer and poor computer space environment Many respondents said that using computers is a necessary part of work, and physical discomfort is difficult to avoid. According to survey data, white-collar workers, it personnel, media workers and other practitioners who have been accompanied by computers for a long time have become "high-risk groups" of computer diseases.
Although "computer disease" will not cause life danger, it should not be underestimated It can cause chain diseases in other aspects of the body and affect the quality of work and life At present, few people go to the hospital to see "computer disease", but the various damages caused by long-term use of computers deserve your attention!
What are the typical symptoms of "computer disease"
① Dry eye, visual fatigue: sore and dry eyes, blurred vision and decreased vision.
② Carpal tunnel syndrome: numbness of palm, swelling and pain of wrist and forearm, swelling and weakness of wrist joint.
③ Neck shoulder syndrome: neck and shoulder pain, periarthritis of shoulder, lumbar spine pain.
④ Computer dermatitis, skin and blood diseases: an electrostatic field will be formed around the power on state display to absorb dust suspended in the air and stimulate facial skin.
⑤ Central nervous system disorders: headache, dizziness, insomnia, anorexia, nausea, depression, mental retardation, forgetfulness, irritability, frequent fatigue, etc.
⑥ Computer depression: long time computer operation forms a "either or" thinking pattern, not used to reaching compromise and understanding with people, losing self-confidence and physical and mental fatigue.
Harm of computer diseases
The damage to eyes should not be underestimated
According to the statistics of the World Health Organization, 90% of people will have different degrees of visual fatigue syndrome if they watch the computer for more than 4 hours a day and more than 4 days a week for a year A survey shows that the proportion of visual fatigue in the latter is 4-6 times that in the former Before using the computer, 3% of people have corneal punctate staining, while after using the computer for 2-4 hours, it will reach 60.3%.
Under normal conditions, people blink unconsciously 15-25 times per minute, but when looking at the computer, due to focusing on the screen, this physiological blink will be reduced to 5-10 times. In addition, when looking at the computer, the eyelid opening will increase the exposed area of the cornea and accelerate the evaporation of tears.
Blink frequently. Be careful. It's dry eye
If there are dry eyes, itching, photophobia, tears, foreign body sensation and other symptoms, this is a typical dry eye disease, which needs to be moistened and relieved with artificial tears. It is best to go to the hospital in time to avoid causing a series of eye diseases such as corneal damage and chronic conjunctivitis.
In addition, to avoid staring at the screen for a long time, rest for 5 to 10 minutes every 40 minutes, look up, close your eyes and do a group of eye exercises, so as to relieve and relax the tense muscles of the eyes.
Sedentary chair becomes spinal killer
In addition to visual fatigue and dry eye, another major harm caused by computer is the impact on lumbar spine and cervical spine.
When using the computer, the cervical spine is in flexion most of the time, and the same posture for a long time is easy to cause cervical degeneration In addition to cervical spondylosis, the harm of long-term use of computer to lumbar spine can not be ignored.
When people lie on their back or side, the force on the lumbar intervertebral disc is relatively small; When standing, the stress of lumbar spine increases; When standing and bending forward, the force will further increase; When sitting forward, the force will be further increased When using the computer at ordinary times, most of them will adopt the posture of sitting forward bending, which will significantly increase the pressure of lumbar intervertebral disc and other structures of lumbar spine.
Adjust the sitting posture to save the diseased spine
According to medical experts, there is a principle to ensure the physiological flexion of the normal spine, which is called "neck pillow, back support, elbow support and waist pad". The height of tables and chairs and the height of the screen shall be adjusted to ensure that the eyes can look down at the screen In addition, keep sitting upright and avoid leaning to one side to ensure spinal balance.
Most of the pain is localized and there is no radioactive pain. This pain can be relieved by posture adjustment, exercise, physiotherapy, or the use of topical anti-inflammatory painkillers.
Beware of "keyboard hand" and "mouse hand"
The scientific name of "mouse hand" is carpal tunnel syndrome. Long term use of the mouse will cause hyperplasia of the transverse carpal ligament, reduce the effective volume of the carpal tunnel and compress the nerves in the carpal tunnel. "Keyboard player" is tenosynovitis. If you tap the keyboard for a long time, the tendon will move back and forth in the tendon sheath and wear the tendon. Over time, it will lead to tenosynovitis
Patients with "keyboard hand" and "mouse hand" often feel swelling, pain and burning of the little finger or even the whole hand, and even hand muscle atrophy and weakness. The fingers cannot be separated, and the ring finger and little finger are chicken claws This kind of injury is directly related to the posture of using the mouse and keyboard, and can not be cured immediately after the injury. It needs long-term adjustment, so prevention should be the most important.
Do more "small actions" after work
Once hand diseases occur, rest is the most important treatment. If necessary, plaster or low-temperature thermoplastic splint can be used to fix the wrist, palm and fingers in the straight or functional position, local injection of drugs or physical therapy can eliminate inflammation and repair damage However, if the symptoms are serious, do not use hyperthermia, but apply ice compress and other cold treatment methods, otherwise the symptoms will be aggravated.
For all kinds of "computer diseases", in the interview, many people also said that they would take the initiative to adjust their rest as long as time permits.
Many people have also given their own tips to alleviate "computer disease":
① Walk more and move your shoulders;
② Change the posture of using the mouse;
③ Do broadcast gymnastics, stretch your arms and legs;
④ Put the water cup away. If you are thirsty, take a few steps to drink water to exercise.
Editor's note: with the popularity of computers and networks, the traditional working method of recording with paper and pen has been gradually replaced by computers. However, in recent years, more and more computer families have frequently encountered the trouble of "computer disease" while enjoying the high-speed and convenience brought by computers.
