The increasing use of mobile devices transmitting and receiving information between people, poses an important problem in the field of social hygiene, arising from the ever-growing level of «global electromagnetic pollution». This term officially introduced in 1995, by the World Health Organization, which included this issue in the list of priority scientific and technical problems of mankind. Biophysical and biomedical research shows that electromagnetic radiation in the microwave range possess the greatest impact on the psycho-physiological state of a person. One of the most informative method for the assessment of the processes of regulation of psychophysiological functions and human health is the analysis of heart rate variability (HRV). As indicated above, the purpose of the study was to analyze changes in heart rate variability while exposing electromagnetic fields from microwave range on human using the developed hardware and software package that includes a mobile phone simulator for GSM band (890 - 915 MHz), and microwave radiation dosimetry recorder and analyzer of intervalograms. Investigations were carried out on 10 men aged 22 to 46 years, who gave informed consent, apparently healthy, using mobile phones routinely. Each man was exposed to the microwave radiation using 6 types of influence patterns within 30 minutes of HRV analysis. Each protocol of a single exposure included 3 minutes of registration of background HRV, 1 minute when exposed to microwave and 1 minute after turning off the microwave source. The study revealed changes in cardiac rhythm during microwave exposure, that were manifested in the form the increase of heart rate variability with an increase of fashion and with decrease in the amplitude of fashion the distribution histograms pulsointervalogramm subjects, or expressed the opposite effect. These two types of effects of microwave exposures were reflected in the shifting of the balance between central, vagotonic and sympathetic functioning regulation of the cardiovascular system of man. This was expressed in increase the spectral power in the respective frequency bands (Fig.1). By repeating the microwave effects began to dominate enhanced activity the sympathetic component of autonomic cardiovascular regulation.
