The presence of biogenic magnetite in vivo in cells is a possible explanation for their sensitivity to weak magnetic fields and SRs. Therefore, the mechanism of ferromagnetism is a scientifically proven method of sensory transduction, which most scientists take into account in studies of human magnetoreception [68; 123; 131]. The connection between the regulation of the activity of the central nervous system and the activity of the cardiovascular system has been studied, scientifically proven and is generally known. Therefore, the possibility of the pathological activation of vascular reactions by an increasing level of frequencies in the low range (gamma) of the Earth's magnetic field was hypothesized. Similar reactions to an increase in low frequencies in the atmosphere can occur in patients with NCDs who have depleted the adaptation resources of the body against the background of pathological metabolic and morphological changes in the heart and blood vessels. This may explain the reason why an increase in the low-frequency contribution of the SRs was significantly associated with an increase in the number of myocardial infarctions [119]. A similar mechanism is confirmed by a theory regarding the existence of sensitivity in the nerve centers of cardiovascular regulation to changes in the electromagnetic field of the Earth [68; 132]. This theory received experimental confirmation. The study revealed a significant negative correlation between baroreflex sensitivity, heart rate variability, blood pressure and increased geomagnetic field disturbances. In this study, baroreflex sensitivity was assessed by the response of blood pressure and heart rate to the intravenous administration of pharmacological agents--phenylephrine and nitroprus \begin{table}

The clinical confirmation of this theory is the fact that an increase in mortality from myocardial infarction is associated with a decrease in baroreflex sensitivity [133]. The most reasonable mechanisms for realizing the interaction of the human body with the frequencies of the Earth's magnetic field should be considered reactions at the quantum level. Since all micro-level processes (nano level and deeper, <1 nm), subatomic structures, atoms, molecules, cell components and tissues are the result of electromagnetic interactions and exhibit the properties of frequency-wave duality, each atom, ion and molecule has a full individual spectrum of nuclear transitions, electronic transitions, rotations and vibrations. Therefore, they can have resonant responses to the same atmospheric frequency. The existence of bioeffective frequencies, which in the range of 0.3-30 Hz cause the resonance of bound ions, has been scientifically proven. In this concept, ions can be considered in the model of isotropic oscillators that have a charge. This mechanism may explain ion resonances that regulate the rate of biochemical reactions in the cells of biological organisms, which is known as cyclotron resonance [134; 135; 136; 137; 138; 139; 140]. The results of laboratory studies confirmed the role of ion cyclotron resonance mechanisms in the regulation of isolated myocardial cells [141]. The human body is a complex, multi-hierarchical system in which many micro- and macroscopic processes occur simultaneously.
