Abstract: Geomagnetic variations of
solar origin correlate with appearance of physiological problems, enhanced
anxiety, sleep disturbances, altered moods, and greater incidences of
psychiatric admissions. We have studied the influence of changes in geomagnetic
activity (GMA) on human
physiological, psycho-physiological parameters and behaviour reactions. In this
article we looked for influence of changes in geomagnetic activity on the
systolic, diastolic blood pressure, pulse-rate and subjective complaints and we
examined 54 working volunteers. Four-way analysis of variance (MANOVA method)
with factors: GMA, day, sex (males/females) and medicaments has been performed.
When we employed four-way analysis of variance, the influence of some of the
factors on the physiological parameters examined turned out to be statistically
significant (p<0.05). Our investigations indicate that most of the persons
examined irrespectively to their status could be sensitive to the geomagnetic
disturbances and the results impose the necessity of systematic investigations
in this field.
