Harm from computers
While working with your computer, you always sit comfortably during long periods of time, but the fact that you feel comfortably doesn't mean that this position is healthy. Constant sitting in one position leads to overload of one group of muscles and at the same time absence of any load of other muscle groups. Constant overload of your hands and arms causes pain in this area, absence of load for back muscles leads to their degradation, violation of metabolism and degradation of vertebral discs. All these negative factors can also provoke headache and pain in limbs. In case with children constant sitting before a computer leads to spinal curvature.
Recent researches established harmful impact of computers on children's growth. Besides, constant communication with computer prevents a child from developing communicative skills with its peers, which in turn can complicate its further life.
Total computerisation of the modern society has gone far beyond the mere upgrade of technological level of industry. Computers have penetrated all aspects of human life and they are no more associated with work, as they have replaced all leisure activities of people too.
People's contact with computers is of complex and many-sided character. When we sit at our computer, we see, here, process the given information and so on. As you see, computer attacks us from all sides. The most vulnerable sense body appears to be our eye-sight.
It is well-known that everything is good within reasonable limits, but in case with computers this limit is very hard to determine and control. Complex interaction of man and his computer means that any restrictions are very hard to establish. Computermania includes several types of addiction. Here we can mention internet addiction, which includes chat rooms visiting and cyber communication. One more type of computermania is even more serious and addictive – this is playing computer games or gaming. Experience shows that gaming doesn't disappear in the course of time. At first a child plays computer games and fails to attend lessons. Later a youngster who plays these games even more intensively and finally a grown-up, who goes on playing games, though it looks rather strange and infantile. Grown-up gamers often have family problems because of their addiction. They pay little or no attention to their families and become selfish and indifferent to other people's problems.
