Cause sleep disorders
Under normal circumstances, people's body temperature is high during the day and low at night. If the temperature difference between them is large, it is easy to enter deep sleep. If you use the computer before going to bed, the bright display screen and the activity of switching programs will strongly stimulate the eyes and nervous system, destroy the law of body temperature change, and make the body temperature that should have been lowered in a relatively high working state, thus affecting the quality of sleep and even causing sleep disorders such as insomnia and MUBI.
Therefore, you should stop using the computer 2 hours before going to bed, and don't put the computer, TV and mobile phone in the bedroom to create a pure sleeping environment. You can soak your feet with hot water or drink a cup of hot milk before going to bed to relieve the symptoms of poor sleep.
Radiation can easily induce cancer.
In addition, computer radiation pollution will affect the circulatory system, immunity, reproduction and metabolic functions of the human body, which will seriously induce cancer and accelerate the proliferation of cancer cells in the human body.
Affect the reproductive system
The human reproductive system is mainly affected by the decline of male sperm quality, spontaneous abortion of pregnant women and fetal malformation.
Affect the cardiovascular system
The cardiovascular system affecting people is characterized by palpitation, insomnia, menstrual disorder, bradycardia, decreased cardiac output, irregular sinus heart rate, leukopenia and decreased immune function of some women.
Affect the visual system
It has a bad influence on people's visual system. Because eyes belong to the sensitive organs of human body to electromagnetic radiation, too high electromagnetic radiation pollution will also affect the visual system. Mainly manifested as decreased vision, causing cataracts and so on.
Hu, who works as a typist in an office in Zhengzhou, has had a hard time recently. Her hands feel numb and hot, and her wrists are a little swollen. After diagnosis and treatment, experts said that she had "mouse hand" and the scientific name was "carpal tunnel syndrome".
According to Xinhua News Agency, experts in hand surgery in Henan Provincial People's Hospital said that carpal tunnel syndrome is a very common civilized disease at present, and its main symptoms are numbness, burning pain and swelling of wrist joints, and inflexibility and weakness of hand movements.
And so on, and the computer keyboard, especially the mouse, is the main "carpal tunnel killer". In addition, with the increase of drivers, the steering wheel has become one of the "killers".
Other professionals who often use their hands, such as teachers, editors, journalists, assemblers, etc. There is a high probability of becoming a patient with carpal tunnel syndrome. According to the survey, the incidence rate of women is three times higher than that of men, because women's wrists are usually smaller than men's, and the median nerve of the wrist is easily oppressed. In addition, pregnant women, patients with rheumatoid arthritis and people with diabetes, hypertension and thyroid dysfunction are more likely to get this disease than the general population.
According to experts, self-care is an effective way to prevent this disease. We should cultivate a good sitting posture at ordinary times, and pay attention to the posture of hands and wrists whether at work or at rest.
For patients with mild early symptoms, rest is the most important treatment. If necessary, the wrist can be fixed with gypsum board to make it straight. If it is serious, it needs surgery. If you don't pay attention for a long time, it may lead to nerve damage, palm blackening and muscle necrosis.
cerebrum
Although the potential of the brain has only been developed a little, it is often felt that the brain is overdrawn after a day's work.
Exposure to radiation in front of the computer every day, poor cardiopulmonary activity and lack of oxygen in the air-conditioned room make the brain work harder in a working environment where it is difficult to play its best, and fatigue will come more easily.
Countermeasures: Make good use of lunch break. Don't simply solve lunch in the canteen downstairs. Take two steps to leave the building. Don't go back to the office immediately after dinner. Find a quiet shade and close your eyes. The cicada singing in summer will completely relax your brain.
Cervical vertebrae
The computer desk that is too high holds up the screen. When you stare at the screen, your neck will stretch forward involuntarily. The cervical spine was originally a backward arc, but now it is twisted into an S-shape. It is easy to be stiff and deformed when it is dislocated for a long time.
Countermeasures: Reduce the height of the computer desk. The suitable height for women is 67 cm, which can ensure the natural bending of cervical spine and reduce the tension of neck muscles.
shoulder
Think about the posture when you use the computer. Do you arch your whole shoulder unconsciously? After muscle tension, the required nutrition increases, but blood vessels are compressed by muscles, reducing the amount of blood involved in transportation. In this way, the nutrition is reduced, the garbage made when the muscles are tense cannot be removed in time, and the shoulders are sore and stiff.
Countermeasure: Adjust the sitting posture. Lean your shoulder blades against the back of the chair, put down your shoulders and lift your chin away from your neck. Rest for 5 ~ 10 minutes every hour, do soft exercise or local massage, and at the same time develop regular exercise habits, and do stretching and muscle strength training for shoulders, neck and upper limbs to increase softness and muscle strength.
eye
I was too focused when using the computer, and the number of blinks dropped from the normal 20 times per minute to 4-5 times per minute. Then the eyes were deprived of oxygen, and the tears decreased, but the light stimulation and radiation entering the eyes doubled. Therefore, dry eyes, decreased vision and blocked lacrimal passages are commonly known as "dry eyes".
Countermeasures: Adjust the brightness of the screen to reduce the light entering the eyes. The ideal screen brightness should be 3 ~ 4 times higher than the surrounding area. In addition, prepare a bottle of tear-type eye drops to relieve dry eyes, but not more than 6 times a day.
stomach
Sitting in a chair for a long time, bending myself into a shrimp, my stomach is hard to move if I want to work hard, my digestion ability is greatly weakened, and my food is piled up in a narrow space, which finally becomes a burden.
Countermeasures: Standing for 20 minutes after a meal gives the stomach a broad space to move and can promote digestion. Moreover, the abdomen naturally contracts when standing, and it can also prevent gastroptosis and abdominal fat accumulation.
wrist
Wrist inexplicable tingling, numbness, weakness, computer family commonly known as "mouse hand." When using the computer, the upper limbs are in the elbow posture. This posture will make the nerves in the wrist bear too much repetitive work and weight, and then be oppressed, gradually forming paralysis and pain in the wrist joint.
Countermeasures: Choosing the right mouse depends on whether the buttons are too tight, whether the elasticity of the buttons is moderate, and whether the mouse size can make the whole palm evenly stressed when holding it.
lower limbs
Sitting in front of the computer for a long time, the idle lower limbs should also complain. If the chair is too high, the legs will be suspended, which will oppress the blood circulation and slow down the hemorheology, causing thrombosis; If the chair is too low, the legs will curl up, pressing the internal organs and affecting the gastrointestinal function.
Countermeasure: Buy a good chair. The ideal chair is: the backrest can be adjusted back and forth; The lumbar pad can move up and down with the inclination of the backrest to ensure that the lumbar support is in the best position in any posture; The chair seat is slightly hard, and the height should be that the knees can naturally bend 90 degrees or lean forward slightly, and the feet are flat on the ground.
skin
There is a lot of static electricity on the surface of computer screen, which can absorb a lot of dust. Your face is so close to it that tiny facial pores are blocked by dust particles. In order not to suffocate, the skin can only make the pores bigger and bigger. The facial skin is getting rougher and rougher, and what feels uneven is the dust particles wrapped in the oil secreted by the face.
Countermeasures: Rub some moisturizing cream on your face before using the computer, or put a cactus on the computer desk. The acupuncture of cactus can absorb dust.
