[Effect of geomagnetic activity on the human body in extreme conditions and correlation with data from laboratory observations].

It was hypothesized based on previous laboratory observations and theoretical concepts that astronauts working at the "Mir" station under zero gravity conditions exhibit enhanced sensitivity to geomagnetic disturbances. The result of studies made it possible to reveal the dynamics of changes in cardiovascular characteristics separately in the main phase and the phase of storm restoration. A similar dynamics of cardiac activity was observed in experimental rabbits during geomagnetic storms.

[Effect of geomagnetic activity on the functional status of the body].

A complicated nonlinear biological system should be in principal more sensitive to the external factors activity including geomagnetic disturbances. The complex of experimental studies based on this hypothesis were done simultaneously in two hospitals in Moscow as well as in condition of space orbital station, where just above-mentioned conditions are the case. This studies revealed that the reaction of astronauts to the geomagnetic storm involves a mobilization and activation of all centers of the sympathetic link, and as a result,--a significant increase and stabilization of pulse (heart rate), decrease of the heart rhythm variability and the power of respiratory waves. This nonspecific adaptation stress-reaction was accompanied by variations in the regulation of vascular tonus which is correspond to specific adaptation stress-reaction. The results of clinical examinations of healthy people and patients with the ischemic heart disease lead us to the conclusion that the reaction to the geomagnetic disturbances are mainly of one type and manifests themselves in deterioration of the physiological status, rheologic blood characteristics and the heart rate disturbances similar to ones observed in astronautes.
