The Effect of Synchronizing the Human Heart Rhythm with Geomagnetic Field Variations: Are There Particular Frequencies?

Abstract

Studies of the phenomenology of the effect of synchronization of heart rate fluctuations in a person at rest with variations of the geomagnetic field in the range of 3–40 min periods have been continued. During 2012–2023, 508 experiments (lasting 100–120 min each) were conducted to monitor minute heart rate indicators in three practically healthy women (55, 45 and 30 years old). Individual experimental samples comprised 328, 113, and 67 records, respectively. It was shown that for each of the three volunteers, in about 60% of the experiments, the wavelet spectrum of heart rates turned out to be very close to the spectrum of synchronous variations of at least one of the horizontal components of the geomagnetic field (X or Y). As well, within the studied frequency range of 3–40 min, three sub-ranges were identified in which the degree of synchronicity of oscillation occurrence was maximum: 3.5 min, 10–12 min, and 33–36 min. It can be concluded that the effect of biogeosynchronization apparently did not occur uniformly over the entire range of 3–40 min, but mainly in these sub-ranges.
