In a short time, from the appearance of the first computer to their mass application, computer technology has conquered the whole world. Today it is impossible to imagine an engineer, an economist or a doctor without the use of computers. Personal computer (PC) has become an indispensable assistant in solving a wide variety of tasks. Using a computer allows you to organize the educational process in a new way: it is much easier and faster to develop memory, attention, spatial imagination, the ability to find dependencies, patterns, classify and systematize the material, the ability to predict the results of your actions.
The information environment – along with natural, spatial-geographic, social, cultural, landscape-architectural, etc. – plays an increasingly important role in professional activities and in the daily life of modern man. The information environment, often referred to as the noosphere, is not homogeneous: it has recently been customary to single out the Internet environment or “cyberspace” within which specific forms of human behavior are manifested.
Despite all the advantages provided by computer technology, it is the source of a number of unfavorable physical factors affecting the functional state and health of users. In case of improper operation and placement, especially in unsuitable premises, the computer modifies the conditions and nature of the work of users of different profiles, sometimes not for the better.
The consequences of the adverse effects of physical factors that accompany the operation of the computer on the health of users are described in numerous research papers by Russian and foreign scientists. In these works, the following possible consequences of the impact of computer systems on the human body were found: eye diseases and visual discomfort, changes in the musculoskeletal system, stress-related disorders, skin diseases, adverse pregnancy outcomes. According to the “Hygienic criteria for assessing and classifying working conditions for indicators of harmfulness and the hazards of factors in the work environment, the severity and intensity of the labor process,” the working conditions of users of personal computers can be classified as hazard class 3 of hazard class 1.
The main diseases of the spine, which develop due to a long time at the computer, are osteochondrosis and curvature of the spine. If the possibility of developing the curvature of the spine is great at an early age, then osteochondrosis and its consequences are dangerous for people of all ages.
