INFLUENCE OF LOCAL GEOMAGNETIC VARIATIONS OF SOLAR ORIGIN ON PERSONS WITH A DIFFERENT BLOOD PRESSURE DEGREE

摘要

A group of 86 volunteers was examined on each working day in autumn 2001 and in spring 2002. Systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were registered. Pulse pressure (PP) was calculated. Data about subjective psycho-physiological complaints (SPPC) were also gathered. Altogether 2799 recordings were obtained. MANOVA was employed to check the significance of influence of the following factors on the physiological parameters: 1) local geomagnetic activity (GMA) divided into five levels; 2) gender - males and females; 3) blood pressure degree - persons were divided into hypotensive, normotensive and hypertensive. Post hoc analysis was performed to elicit the significance of differences in the factors' levels. Average values of SBP, DBP, PP and SPPC of the group were found to increase statistically significantly and biologically considerably with the increase of local GMA. Hypertensive persons were found to be the most sensitive persons to geomagnetic storms.
