Public health by computer techniques big

Many people can not imagine if there was no computer in their life would be what some people are sitting in front of the computer all day, which will have a question: "I sit in front of the computer 10 hours, non-stop typing, in How can such a situation so that health is not impaired? " ■ carefully cation Mainly in the display. However, not as you imagine, as in the case when the atomic bombing of nuclear radiation, electricity did not display any nuclear radiation. However, the display at work would be a lot of electromagnetic radiation, which will air ionization occurs: all around us in positive charge (positive ions), not to them and after a storm in the sea or mountains formed by engaging in negative charge mixed. Negative charge and more useful, positive charge on the more harmful - they enter the lungs through breathing, and then be transported with the blood circulation to the body's various organizations, in order to change the cell's charge. We have, in insomnia, nervousness, irritability, palpitations strengthened immune system decline. In addition to electromagnetic radiation, the display is switched on around there will be a static electric field, it will almost respirable dust the entire room in their own field. Sitting in front of the computer, so you breathe in such a dry mucosa, easily lead to allergies in the air containing dust particles. Therefore, you may from time to time to a stuffy nose, itchy throat, or even dermatitis - red spots and rash. Completely avoid electromagnetic radiation is impossible, however, weaken the harmful effects of it is very simple - the use of the production of 1996 display to be careful when cleaning the office environment, since positive ions will be firmly adsorbed on dust particles. Do not place the computer around the mountains of paper and documents, to all necessary documents into the cabinet categories. Computer desk surface with wet cloth dipped in anti-static agent. Regular fenestration ventilation. In the work do not forget to rub some moisturizing cream face, it is best to prevent the function of tension. Chamomile extract the evening with wet towels (more simplest way is to use wet chamomile tea) directly deposited in the forehead and cheeks. ■ keep a distance from Dazzling display on the screen and has been in the flash. We look at the display time to stare at that little blink of an eye, so eye muscle fatigue, mucous membrane-fat dry eye, eye redness, inflammation, pain. In front of the computer after 4 hours of uninterrupted work, almost everyone's eyes will have the feeling of pain and trachoma. If you close the distance from the monitor, some time you will reduce the visual impression: the eyes have become accustomed to the sharp focus in the nose, so that will not relax for a long time. Sometimes you with "computer" work face-to-face for several hours after starting to see things eye shadow, computer desk it is very difficult to see objects outside. To avoid their own visual impairment, monitors from the distance you need to face 70-80 cm, slightly lower than the binocular vision, the brightness was adjusted to not to the degree of eye fatigue. Work in front of the computer room is not too dark, not too bright. Is an ideal office environment - the room's brightness and the brightness of the same screen. On the screen can not show your face, lights, bright objects in the images (all of the lighting will be doubly so eyestrain). If you wear glasses, with an allocation to their own anti-reflective lens coating. In order to prevent dry conjunctiva, you can drop in the morning when some of the same ingredients with our tears the drops. Light at night can be enough tea cooked a few minutes of wet tissue, will soon eliminate the congestive and fatigue. ■ seated to the right Now that is not about the problems caused by the computer itself, but we are used to the sitting position. How can we sit and take the consequences of this depends entirely on our own. Can sit on low chairs or a small square stools without back, mounted high arm, head, and under the table跷着二郎腿difficult. This position you will work one hour headache, back pain, neck and shoulder numbness, arm flexibility. Such a posture to maintain one to one and a half years you will receive double chin, cervical stiffness. If the elbow often lower than the wrist, and hand carried high, nerves and tendons are often oppression, will begin to numb the hands, the fingers lose their flexibility, frequent joint pain. There is also a complication of incorrect posture - "occupational cramps." 100 years ago, the Registry law firm in a long-term after copying the disease - as a result of nervous activities of the right hand fingers when in pain. The disease is now frequented by the hands of those wrist below the keyboard non-stop beating people. The above problems is the best solution - to buy a dedicated computer chair, and sat on it to follow the "three right-angle": computer desk formed under the knees at right angles to the first, the thigh and the back is the second right-angle, arm in the formation of a third right-angle elbow. Scapula against the back, shoulders down, chin not go near the neck. What to do in the rest of local massage: Massage fingertips from the beginning up to the forearm massage. Tired from time to time raised his arms up, fingers vibrate to help venous return of blood better. Suffering from premenstrual syndrome, spasm of the women and the women do not easily tighten the belt line, wearing a tight pair of jeans sitting in front of the computer - this can easily lead to severe abdominal pain. While other women are not the best song from time to time, a loose skirt or pants with the belt tension. ■ Institute of rest All the women in front of the computer work the best half an hour every 2-3 minutes to rest the eyes, every hour 10 minutes to do what the other parts of the保健操. However, when tension in the workplace can not be so regular "rest", then how to do? Let us rest and relax the muscles enough for 2-3 minutes. Therefore, frequent changes in posture, back on to the back, head back, eyes looking at the ceiling, the United States and the United States to伸个懒腰. Reflections on the Institute side by side to look out the window shifted to the computer screen. In some offices in order to achieve this objective have put fish tanks: watching the water and fish will make you relax and at the same time without affecting your concentration. Every two hours if you can have more than 20 minutes of rest, I suggest you to work a walk outside. ■ For a few misunderstood computer Mentioned that there is a risk of cactus can absorb electromagnetic radiation, which will be issued by the gill anion, and the harmful effects of positive ions. In fact on a computer monitor near the cactus needle aspiration can only gray. However, it does like this radiation, in the vicinity of radiation sources will grow well, especially in a time when the sun shines. The second misunderstanding, the computer screen would undermine the protection of electromagnetic radiation. In fact if you work using the old computer screen on the protection of good eyesight, and the grounding line of computers local to avoid static electric field. In other words: the old and the new display monitors mainly from the radiation is not positive, but the side and behind the display. Therefore, if the love of your colleagues, not to the back of the display is directed at their colleagues in the back of the head or the side of the body. Computer will not result in any neurological disease, however, will cause a few cases of relapse in patients with these diseases. Often the screen flashes the brain cells provoke sympathy, pulse epilepsy patients make these resonate more brain cells to the regional extension. Thus, the beginning of convulsions. Women often make an issue of tension is that the computer on during pregnancy have an adverse impact on women. This problem, many scientists are still carefully studied, but so far no harmful factors are not found.
