Impact of computer on human health
The life of a modern man is closely connected to computers. Adults and children use personal computers and laptops, as well as complementary devices such as printers, scanners, and modems, for personal, professional and educational purposes.
With the advent of the Internet, it has also become the best way to find information, business communication, and recreation. In general, many of us find it difficult to imagine life without a computer. But in addition to numerous advantages, the computer has its disadvantages. This is its impact on human health. The computer has become a source of many diseases associated with exposure to electromagnetic radiation, with the load on the organs of vision, respiratory organs, muscles, and joints. Let us consider each of these risk factors in more detail.
Influence of the computer on a backbone
How computer use affects the spine and surrounding muscles: A fixed posture. This weakens the muscular corset of the spine. Some muscles are switched off and others are constantly tense, which can result in the myofascial pain syndrome. Prolonged static stress causes premature wear of the vertebrae and intervertebral disks. Bent back. If the monitor is too low, a person has to lean forward, bend his back with a wheel while working on the computer. This increases the load on the front edges of the intervertebral discs and can lead to protrusions (protrusions outside the vertebrae) and hernia. Inactive lifestyle and poor nutrition. Many people who have to work long hours at the computer stop watching their physical fitness and diet. This hurts the spine and all joints.
Each device that consumes or generates electricity creates electromagnetic radiation. This radiation is concentrated around the device as an electromagnetic field. Electromagnetic radiation cannot be seen, heard, smelled or touched, but it is present everywhere. There is no conclusive evidence that the electromagnetic field created by the computer is dangerous. But the information available on this issue is not yet sufficient to provide a definitive answer. So it is better to be careful. So how do you protect yourself from potential health risks? It is necessary for this:
- Purchase an LCD monitor, because its radiation is much lower than that of a CE-electron beam monitor;
- The system unit and monitor should be as far away from you as possible, it is safest to install the computer in the corner of the room so that the radiation is absorbed by the walls; special attention should be paid to the placement of monitors in the offices;
- Do not leave your computer on for long periods if you are not using it; although this will speed up the wear and tear of your computer, your health is more expensive;
Respiratory diseases, which develop due to long-term work with computers, are mainly allergic. This is because, during the computer's operation, the monitor case and the board in the system unit are heated up and emit harmful substances into the air. Also, the electrostatic field of the computer attracts dust, which settles in our lungs. At the same time, a running computer dries the environment and reduces air humidity. Each of these factors has a detrimental effect on the lungs as well as on the body as a whole.
To reduce their impact it is necessary: as often as possible to do wet cleaning of the room and air it; to increase the humidity to put an open container of water (such as an aquarium or a decorative waterfall).
Try to listen to the recommendations, which have become increasingly apparent in the press and other sources of information, and your communication with the computer will not harm your health.
Load on your eyesight
The most important factor is the load on your eyesight. It is precisely because of the short-term visual load that a child (or other users) experiences headaches and dizziness. If you work on a computer for a long time, visual fatigue can lead to a steady decrease in visual acuity. However, it is not the computer that is the main cause of myopia in a child. A huge role in this plays heredity, television, reading in the dark. When the case is properly set up, the load on the computer's vision can be significantly reduced.
- First of all, jerking off the image is harmful because of the low frequency of vertical refresh or because of the poor quality of the monitor.
- The second most important factor in eye fatigue is the content of the image.
- the eye can best perceive a static, large color image accompanied by sound. Therefore, it is safe enough for a child's or adult's eye to view pictures or photos accompanied by narration.
- And, finally, the real killers of the eyes - it's games. Moving images, small elements - all this leads to such fatigue, which is removed very soon.
