INFLUENCE OF ELECTROMAGNETIC EXPOSITION FROM INFORMATION AND COMMUNICATION TECHNOLOGIES MEANS ON PHYSIOLOGICAL INDICES OF THE HUMAN BODY
Introduction. Means for working with information - communication devices (personal computers, laptops, tablet computers, and smartphones) are leaders in the dynamics of modification and updating of the technical base. This is accompanied by a dynamic change in the electromagnetic characteristics of computer equipment. The amount of information faced by young people receiving education in the modern world is growing. In students, this is accompanied by long-time work with personal computers (PCs) not only in the classrooms but also at home, in the process of preparing for classes. It is important to study the effect of PCs' electromagnetic factors on the user's body, taking into account the exposure. Material and methods. The was studied memory, attention, non-specific adaptation reactions, the adaptation potential of the cardiovascular system (CVS), the vagosympathetic interaction index (VII), skin temperatures, and biological age in students - PC users. The PC determined the strength of the electrostatic, electric and magnetic fields of monitors, system units, laptops and tablet computers of various types and manufacturers. There was calculated the individual electromagnetic exposure (EMEi). Results. Measured values of electromagnetic fields (EMF) of the studied PCs were revealed to be below the maximum permissible levels. The determination of the number of indices for students - PC users showed that they were within physiological norms. Discussion. There is an impact of individual electromagnetic exposure on the studied indices among students - PC users. Conclusion. Correlation analysis by Pearson allowed identifying the most important relationships of electromagnetic exposure with investigation of memory (R=-0.383; p<0.001) and attention (R=0.326; p<0.001) and nonspecific adaptive responses (R=-0.325; p<0.01), VII (R=0.618, p<0.001), the adaptive capacity of the cardiovascular system (R=0,267; p<0.01) and amplitude difference of the skin temperatures ( R= -0,284; p < 0,01). Biological age was associated with a weak positive dependence (R = 0,231; p < 0,05).
