Abstract

Background: The geomagnetic environment is very sensitive to changes in “Space weather” (SW) and its manifestations on the Earth. The human body is adapted evolutionarily to the slight alterations of the geomagnetic field (GMF). Objective: The aim of this work is to test the hypothesis on whether different levels of GMF causing specific stress-reactions in humans' autonomic nervous system (ANS) depending on the levels of GMF. Subjects & method: This is a randomized control study, in which took part n=62, 18-24 years old healthy male volunteers. We measured their ANS responses via heart rate variability (HRV) and stress index (SI) to compare them with the K index of GMF (the magnitude of GMF during geomagnetic storms (GMS)). Experiments were performed as in natural as well as in the lab conditions by simulation of different geomagnetic activity (GMA) using the pilot device of GMS compensation/simulation. Results: In comparison with quiet magnetic days (K=1-3), the initial values of HRV significantly shifted towards intensification of the sympathetic part (SP) of the ANS during days of GMSs (K=5-7). Significantly shifts in both parts of ANS (sympathetic/parasympathetic) were observed during short-term exposure to simulated GMSs (K=7, the magnetic induction B=200nT) in comparison with conditions during compensated GMSs (K=0, B=0-5nT). Conclusion: The results indicate an intensification of the ANS as a stress reaction in healthy humans when it is exposed to high levels of GMF in both natural or simulated conditions, however, the initial regulation types of the ANS (balanced/parasympathetic) results in different dynamics in its variation as a function of the GMF level.
