Computer and health. The influence of the computer on human health.
However, with the correct mode of operation, their harmful effects can be minimized.
Harmful factors, or is it all so terrible in reality?
1. Electromagnetic radiation - this factor has long been "obsolete".The whole secret is that modern monitors are absolutely safe for the human body in this respect. An exception can only be made by owners of old monitors - but these are getting smaller.
2. Influence on vision - the screens of modern monitors almost do not flicker, and the load on the eyes is almost the same as when reading a book or watching TV.
3. Sitting position is really one of the most harmful aspects of working with a computer. Stagnation of blood in the pelvic region, load on the musculoskeletal system, deposition of salts, scoliosis and osteochondrosis, varicose veins, obesity is the incomplete list of what can lead to in the sitting position of .On the other hand, working at a computer is by no means the only one in this respect, it's no secret that the term "sedentary work" arose long before the advent of the miracle machine.
4. The load on the joints of the hands during work on the computer can lead to numbness and weakness of the pads of the fingers, as a consequence - to the disruption of the joints of the hand. However, secretaries-typists in the Soviet era lived even worse, because knocking on the rough keys of typewriters was much more difficult.
5. The impact of dust and dirt accumulated in the computer, on the keyboard and mouse. Scientists claim that the microbes on the keyboard are hundreds of times larger than on the lid of the toilet - hence the so-called "dirty hand disease".And the dust in the system block can lead to various allergic reactions( which is still not comparable, say, with an abundance of dust on the bookshelves, which daily have to face the workers of libraries).
6. Influence on the psyche and the nervous system is perhaps the most dangerous of all the negative factors behind computer work. Especially fraught with computer addiction for the unstable psyche of adolescents. Similar can be unless the dependence on gambling( slot machines, casinos).Igromaniya, Internet addiction can lead to disturbances in appetite, sleep, irritability, violation of attention, memory, increased fatigue, depression, stress. This, in turn, leads to the emergence of more serious diseases of the nervous and cardiovascular system, diabetes mellitus, gastritis, peptic ulcer, impotence.
As can be seen, the harmful effect of computer on human health is sometimes too exaggerated .The described risk factors are typical for many other types of work( except perhaps the last point).What is the secret of maintaining health while working on a computer for a long time? Surprisingly, but here all the recommendations are far from new.
We protect health by working on the computer
To protect yourself from the harmful effects of the eye, you need to periodically( every 15-20 minutes) look away from the screen: look through the window, for example. Good gymnastics for the eyes: rotation of the eyeballs, frequent blinking, focus on one point, etc.
Once a hour you need to break away from work in a sitting position: just walk around the room, do a few exercises to warm up the joints, prevent blood stagnation( very good sit-ups, torso torso).
Do not forget about diet and sleep. If you eat "fodder" food and sit at the computer until two in the morning, the body will immediately announce a "strike".Walking in the fresh air, rejection of bad habits also will not harm.
To avoid fatigue of the spine, you need to maintain proper posture. It's no secret that properly selected chair and table height - a guarantee of comfort while working at the computer.
The computer also needs proper care. At least occasionally you should remove the cover of the system unit and gently vacuum the parts on which the dust has accumulated. Special care is required by the keyboard - at least once a month, it must be disassembled and processed parts, preventing the accumulation of dirt( and therefore, all sorts of microbes, fungi, viruses).
Elementary compliance with these "safety rules" will minimize the harmful effects of the computer on the human body.
