Abstract

Physiological effects of 40 times weakened geomagnetic field achieved by shielding were studied on rats (st. Wistar). Systolic arterial pressure and intersystolic gap were recorded and spectrum analysis for heart beat variability was performed. It was shown that already during two first days of shielding one could watch an essential decrease in heart beat rate and increase in high-frequency (parasympathetic) component of its spectra variation. Increased parasympathetic nervous system activity was registered. Adaptation of animals to the conditions of weakened geomagnetic field during a 2-week period was recorded.

Keywords:
