Computer and health

A computer . The controversy around this, so necessary for today is the subject of household did not abate for a long time. Radiation, flicker … blurred vision, dry skin …

Those who are "lucky" to work for lamp monitors, you know that after a day spent at the monitor, my eyes feel very uncomfortable. Itching, burning, whites turn red and the eyelids are closed just tired. All these feelings are obvious symptoms of the disease called "dry eye syndrome," and if one is not paying attention to them, can then give a lot of trouble. The culprit of the disease appears, incidentally, is not just a computer – and make their contribution too dry conditioned air and dust in the street, and even an unbalanced diet, which leads to a lack of vitamins in the body. If individually these factors may not be sufficient for the development of dry eye, so together they are the most unfavorable way.

 

 The most advanced technology in the world can be considered monitors the implementation of thin-film monitor TFT (Thin Film Transistor). Thanks to the active-matrix can significantly improve such characteristics tft monitors, as speed contrast and clarity. In addition, it is believed that the tft monitors are absolutely harmless to human health, in contrast to the conventional tube displays. Although, I think time will tell. Flat-panel monitors naturally save the workspace at the office or at home, and a variety of design solutions will contribute to the creation of the style of the room. Of course, today, any self-respecting and caring for their employees the firm is staffed by LCD monitors.

One way or another, but for the monitors we spend considerable hours of their time working as well as home …

Smarting and pain in the eyes, tearing, redness of the eyelids and eyeballs, pain in the forehead, fatigue

    All these obvious signs of the so-called "display" of the disease, the cause of which is the duration of continuous monitoring of the screen. The first signs of asthenopia (eye fatigue) are observed after 45 minutes of continuous operation of the screen.Visual function decreased abruptly after two hours. When using a short break after every 1-2 hours of work, significantly reduced rates of fatigue. At the same time, long, longer than 4 hours stay behind the screen can lead to accumulation (accumulation) of fatigue. Should comply with the required distance from the eye to the monitor – The monitor should be 70 cm, stand so that it does not fall bright light bulb or sunlight.Here is what requirements must comply with the correct monitor if the computer is used for design and layout, the monitor should be at least 17 inches, the refresh rate of at least 85 Hz, the smaller the grain of the monitor, the sharper the image and is easier on the eyes. The grain size should not exceed 0.28 mm.; To exclude all sorts of glare on the screen. You should also avoid large contrast between the brightness of the screen and the surrounding area. In no case should not operate a computer in a dark or dimly lit room. Evening illumination workroom desirable bluish color with brightness is approximately equal to the brightness of the screen. Daylight is also recommended that the display around a blue background – at the expense of painting the walls. Every 40 – 45 minutes to conduct a brief physical training mikropauzu: eye rotation in a clockwise direction and back, light gymnastic exercises for the whole body (all of it within a few seconds.)

 Those who spend at the screen for more than 8 hours a day, have a much greater chance of becoming a victim of blepharitis – inflammatory diseases of the century.Symptoms of a rather disappointing: first, you feel an itch and a constant eye strain, and then his eyelids redden and swell, then the same along the ciliary edge may appear small flakes like dandruff. Needless to say, that blepharitis is not only cause a lot of discomfort, but also adversely affect the visual appeal. Even the best eye makeup does not help the situation, the more so in this case s abolevanii painted eyes and is not recommended.

Decrease in visual acuity – another very common problem, which, according to experts, could face each of us. Even kids too carried away playing computer games, get to risk, and that really there to talk about office workers! The main problem of the perception of our eyes from the screen of information is that the image is composed of many separate points, constantly flickering. Meanwhile, the human vision poorly adapted to the perception of such images and text. If the solid lines on the paper we read, "easily", then to detect information from the monitor to our eyes need to expend much more effort. As a result of excessive stress is constant, there are functional failures and, consequently, the vision begins to decline steadily.

If we had a long, stooping, sitting in one position, the muscles of the back there is tension, congestion, and as a result – swelling and inflammation. And all this low back pain and muscle blockade. Why blockade? Because these muscles compress the nerves that extend from the spinal cord in the spine, causing pain and sensitivity of the violation. If the compression of the nerves were coming out of the cervical spine, the sick and numb are the neck, shoulders, arms, and if – in the lumbosacral, then, accordingly, the focus will be trouble loins and legs.

 Skin allergies, hair loss, lack of oxygen

    Computer as the other electrical equipment, a source of electromagnetic radiation.The electrostatic field contributes to the fact that the particles of fine dust deposited on the hands of the face and neck, causing allergic reactions, dry skin and hair. In the room where computers work, should be a good ventilation system. The minimum area for a video monitor 9.10 m 2. Highly undesirable visual contact with other monitors employee or TV screens. Do not be redundant and ionizers (such as a chandelier Chizhevskogo) and humidifiers.

 Nervousness, high blood pressure, memory loss and sleep

    These are all signs of stress, which can not be avoided at any job. However, the level of stress depends on the quality of your computer. The machine, which "freezes" loses essential information, slowing the pace of work is not conducive to peace of mind. So that the computer is more powerful justify itself in the best way.

First-aid

All the identified problems have solutions, the main thing – do not let them "take its course." Ophthalmologists have long developed a host of recommendations, and to avoid dry eye syndrome, and reduced visual acuity, and blepharitis. Let's say even more – all of these recommendations are well known to us, but many follow them for some reason not in a hurry.

 Mode of operation. Of course, ideally, the computer should be no more than 4-5 hours a day, but under present conditions it is not always possible. In this case, try to do at least a 10-minute breaks after each hour of work. If possible, move to fresh air or just to look out the window. The eyes are very tired? Blinked 20-30 seconds, paint with pupils in the air "eight", leaving the head still. These simple exercises will help you feel better. In the extreme case please have the preparations of artificial tears – they do not treat dry eye syndrome, but effectively relieve fatigue and sore eyes.

If possible, it is worth to buy LCD monitor, since its radiation is much less common than CRT (cathode-tube monitor).

 Comfortable workplace. The table height should be 75 – 85 centimeters. It is better to sit on a rotating chair with armrests and lumbar supports. Need to adjust the keyboard to the wrist were not suspended. The most comfortable mouse – big enough, with a light body and a heavy ball.

For the prevention and treatment of carpal tunnel syndrome should take care of the ergonomics of the workplace, as often as possible to interrupt the work and perform a small set of exercises for arms, which can be found below.

 The correct hand position.

    1. When you use the keyboard, the angle of bend your elbows should be straight (90 degrees)

    2. When working with a mouse wrist should be straight and lie on the table as far as possible from the edge.

    3. Stool or chair with armrests should be, as is desirable for the special convexity wrist (mouse pad, keyboard, or a special form of a computer desk with bulges).

Power. Yes, what you eat, not only reflected in the figure, but in his eyes. For the prevention and reduction of age is necessary to enrich your diet products with vitamins A, B2, E, C. Useful for cheese, containing calcium, lean meats and fish, blueberries and other fresh fruit. In the cold season, when beriberi is a familiar phenomenon, drink special vitamin and mineral complexes – they help you stay in shape even in the harshest winter.

 Hygiene. According to statistics, women are more likely to suffer from diseases of the age than men, and this is solely due to hygiene issues. When applying makeup you will inevitably come in contact with eyelids and eyelashes, so if on your fingers or cosmetic brushes bacteria, increases the risk of infection delicate eye area. To avoid this happening, do not forget at least once a week, wash all brushes and sponge with warm soapy water, without much need to avoid touching the eyes, hands, do not use other people's shadows or mascara. In addition, experts recommend a daily basis to carry out hygiene century – to make a gentle massage and apply blefarogeli in the evening do not forget about warm compresses to blefarolosonom or independently prepared decoctions of herbs (chamomile, gammamelisa, etc.). All these procedures will take you 10 minutes of strength, but what benefit will bring invaluable.

 Themselves with the mustache …

When the disease can be managed independently, but when you need to run an ophthalmologist? In general, an appeal to the specialist does not hurt in any way.However, if a burning sensation in the eye and redness occur only from time to time, and then, after many hours in front of the monitor, you can do on their own. Memorize all of the above advice and try to adhere strictly to them, paying particular attention to hygiene century. Even if you are very tired and fall to the ground, do not skimp on nightly ritual – your eyes will tell you "thank you".

In those cases, when the eyelids always look swollen, reddened, itchy eyes or not is slowly but surely declining to go to reception to an ophthalmologist is necessary, and the sooner you do, the better. You know, treat the disease should be professional, you're gonna do better than their prevention.

But it's all about us … I suggest you a few recommendations for your kids, because as you know, health must be cared for in his youth … Of course, your baby has increased pressure on the brain, the eyes, the mind. And in your abilities to make sure that this load was not excessive. Today, the main "threat" – from the computer screen and TV.About them and will be discussed.

- If the child is often long and there is one on one with the screen of the virtual world, it has inhibited the development of independence and activity. And no wonder: he sits for hours without showing little or no physical activity, and if they take certain decisions, it is only given in the framework of a computer game.

- Do not get the proper development of creative thinking. Indeed, the child does not need to be as the birds were sitting on the branch and flew many, it has everything on the screen, it only operates with ready-made images.

- Do not be surprised if your child has a habit linger in front of TV or computer, and begin to develop overweight or myopia, if it is bad to sleep at night and by day become lethargic and apathetic .- Computer and TV produce a constant flow of information. If he is seen without a break for a long time, it does not receive the development of critical thinking ability, evaluate, synthesize what they saw and heard. This means that information is absorbed without the "filters", without discarding unnecessary.Especially in childhood, these mechanisms are only just emerging. Hence the congestion, and fatigue, that sooner or later affect learning.

- And yet another delay, triggered by the virtual world: the so-called artificial socialization. Passive acceptance screen life is not conducive to the development of adequate communication skills with others.

- Try to discuss with your child what he saw, ask questions, "How do you think, can it really be?" "Was the hero?" "What do you think about this?"

- And, of course, limiting the time sitting in front of the screen, try to keep the child's activity was varied: games, sports, walking, socializing with peers.

Well, I hope you will gather from this article and for myself that something important ..Suppose we can not live without a computer, but forget about their health is not worth .
