When computers serve us, they are also competing with our health. In addition to mouse hand, cervical spondylosis, myopia, agraphia, etc., a new round of computer diseases has also begun to spread everywhere, so I would like to remind everyone to be vigilant and pay attention to disease prevention.
eye trouble
Sitting in front of the computer for a long time, because the visual object is close, the ciliary muscle of the eye is forced to be in a state of contraction and tension, thus making the lens bulge to adapt to the near object. If the eyes are in a state of tension for a long time without rest, it will lead to myopia. Excessive visual fatigue can also lead to the obstruction of aqueous humor operation, leading to glaucoma. Therefore, when operating the computer, you should always move your eyes and do eye exercises regularly.
cervical spondylopathy
Computer operation makes people's head lack of activity and keep the same posture for a long time. If it takes too long, compensatory hyperplasia of cervical vertebrae will occur. Cervical hyperplasia can compress nerve roots, cause scapulohumeral periarthritis, limit the activity of upper limbs, and in severe cases, people cannot take care of themselves. Cervical hyperplasia can also lead to compression of vertebral artery supplying occipital part of the brain, causing abnormal blood supply to occipital part of the brain, and symptoms such as headache, dizziness and memory loss.
protrusion of the lumbar intervertebral disc
Long-term tilt posture combined with lack of activity can easily lead to lumbar hyperplasia of computer operators, and make the posterior longitudinal ligament tense and inelastic, causing lumbar disc herniation and compressing nerve roots. If the sciatic nerve is compressed, it can lead to radicular sciatica, low back pain, lower limb pain and dyskinesia.
varicosity of lower limbs
Due to lack of activity, the venous pressure of lower limbs, which depends on skeletal muscle contraction and reflux, will increase, and long-term venous cavity expansion will cause venous valve insufficiency, which will eventually develop into organic sexual dysfunction and lead to varicose veins of lower limbs.
neurosism
People who use computers for a long time may have serious neurasthenia symptoms, such as emotional instability, irritability, dizziness, headache, insomnia, forgetfulness and so on.
fat
People who sit in front of the computer for a long time will have abnormal distribution of gravitational adipose tissue due to lack of exercise.
Fat accumulates in the lower abdomen and back, which easily leads to centripetal obesity.
Hemorrhoid disease
Increased abdominal pressure and insufficient activity can make the perianal venous return not smooth, leading to tortuous rectal venous plexus, and dry stool is easy to cause hemorrhoids.
Computer dependence syndrome
Patients are like addicts, they can't live without computers. Too long will lead to abnormal personality, such as withdrawn, eccentric, indifferent to colleagues around, what happened at home and abroad, abnormal interpersonal relationship, and even lead to abnormal personality.
In addition, long-term computer operation can also induce or aggravate the following diseases: urinary calculi, varicocele, arthritis, inguinal hernia, lower digestive tract tumors, spinal stenosis and so on.
Reduce computer damage six attention.
People pay more and more attention to the negative effects of computers on human physiology and psychology. How can we reduce the harm?
Enhance self-care awareness: pay attention to proper rest during work. Generally speaking, computer operators should rest for about 1 0 minutes after continuous work. And it is best to move your hands, feet and torso outside the operating room. At ordinary times, we should strengthen physical exercise and strengthen our physique.
Pay attention to the working environment: the light in the computer room should be suitable, neither too bright nor too dark, so as to avoid interference caused by direct light irradiation on the fluorescent screen. The studio should be kept ventilated and dry, so that those harmful gases can be discharged as soon as possible, and the noise should be reduced as much as possible with a non-impact printer.
Pay attention to the correct operating posture: the center of the computer screen should be installed at the same height as the operator's chest, and it is best to use a chair with adjustable height. When sitting, you should have enough space to stretch your feet and don't cross your legs, so as not to affect blood circulation.
Pay attention to protect your eyesight: avoid continuous computer operation for a long time and pay attention to rest. To maintain a most suitable posture, the distance between the eyes and the 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 exposed area of the eyeball.
Pay attention to supplement nutrition: computer operators work too long in front of the screen, and rhodopsin on the retina will be consumed, and rhodopsin is mainly synthesized by vitamin A.
Therefore, computer operators should eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs and other foods, and supplement vitamin A and protein. Drink more tea, tea polyphenols and other active substances in tea can help absorb and resist radioactive substances.
Pay attention to keep the skin clean: there is a lot of static electricity on the surface of computer screen, and the dust accumulated for a long time can be transferred to the exposed skin of face and hands, which is easy to cause macula and pigmentation, and even cause skin lesions in severe cases.
