SUMMARY
The analysis of professional literature proves that there are documented facts of the biological influence of electromagnetic fields on humans and animals. Moreover, the sensitivity of neuroendocrine and cardiovascular systems, blood system, gastrointestinal tract, etc., to such influence has been established.
The state of the autonomic nervous system (ANS) in people who have professional contact with ultrahigh frequency electromagnetic fields (UHF EMF) of non-thermal intensities plays a significant role in disclosing the essence of the microwave influence mechanisms and developing the corresponding preventive activities.
To solve the tasks some experimental research has been carried out when alongside with general clinical and biochemical blood tests, abdominal sonography, chest fluorography, electroencephalography (hyperventilation was used as a stimulant), the following functional tests were implemented for all patients: identification of dermatographic urticaria, Aschner-Dagnini oculocardiac reflex, Danielopolu clinostatic reflex or clinostatic hypertension, Prevel orthostatic reflex or orthostatic hypotension, Ortner’s syndrome. All the investigated individuals were divided into 5 groups based on the professional experience: people with professional experience of up to 5 years, those with 6-10, 11-15, 16-20, and above 21. The control group of 30 people consisted of individuals of the same age and sex, serving in the same conditions, but without any contact with the UHF EMP.
According to the functional tests, one can state that objective evidence of dysautonomia was more frequently observed with persons who had more than a 10-year professional experience. These dysfunctions corresponded to the threshold of functional disorders and had no specificity. One can assume that the mechanisms and directions of changes occurring in the ANS are of the same nature. This conclusion may become fundamental in determining the list of the most informative and accessible indicants for implementation in clinical practice. It seems that we are witnessing the phenomenon of chronic stress, when there is a dysautonomia of the ANS with a predominance of the sympathetic component due to the reserve capacities of the body, with a further depletion of its compensatory capacities.
