This confirms the improvement or decrease in the ability to navigate using radiofrequency magnetic fields at the Larmor frequency and the dependence of these effects on the angle between geomagnetic fields and radiofrequency magnetic fields [147; 148; 149; 150]. One study [121] put forward a hypothesis that may also explain the different degrees of response of different tissues in the human body to the influence of SRs. Tissue cells of different organs have fundamentally different atomic compositions. When interacting with external magnetic fields, an atom of each substance has individual biophysical characteristics of changes in the magnetic moments of electrons and nuclear atoms, which are predetermined by its quantum mechanical characteristics. Depending on what class of magnets the atoms of different chemical elements belong to, they will interact with the external magnetic field in different ways. Depending on the type of magnetic reactions, substances are classified as paramagnetic, diamagnetic or ferromagnetic. The atoms of sodium (Na), potassium (K), calcium (Ca), magnesium (Mg) and oxygen (O) have paramagnetic properties. They are magnetized in the direction of an external magnetic field. Carbon (C), silicon (Si), hydrogen (H), sulfur (S), phosphorus (P), chlorine (Cl), iodine (J), bromine (Br) and copper (Cu) are diamagnetic substances that can be magnetized by an external magnetic field. It is important to note that 99% of the molecules in the human body are formed precisely by carbon, hydrogen and oxygen, which have the properties of diamagnetic materials. Therefore, it is believed that hydrogen is of great importance in responding to changes in external electromagnetic fields [3]. With an increase in the strength of the external magnetic field, an increase will occur in the oppositely directed magnetic moments of the elements of the paramagnetic and diamagnetic groups. Because of this, there will be an increase in the precessional effect of vibrations in the electronic orbits of individual atoms. The structures of the tissues of different organs contain different microelements and have different specific atomic compositions. Therefore, the total reactions of the moments of atoms forming molecules and cellular structures in different tissues and organs will be different. This may cause different functional responses of organs to changes in SRs. As an important response mechanism in the magnetobiology of the human body, it is necessary to consider the secondary reactions of organs and systems to external electromagnetic influence by SRs. Therefore, as an option to explain the possible pathogenetic influence of the low-frequency (gamma) components of SRs, we can consider precisely the secondary reaction of the body's organ systems. This can be described as follows: Fluctuations in the frequencies and periods of the plasmaspheric resonator cause changes in the electron concentration in the plasmasphere. This synchronizes the body's rhythms and causes stochastic resonance. For example, resonance phenomena in the neurons of the brain cause an increase in frequencies in the gamma range. In response to this, a stress-adaptivereaction of the body occurs with the activation of the hypothalamic-pituitary-adrenal axis. There is an increase in the production of glucocorticoids and catecholamines. The body's stress response is realized, which causes the activation of blood coagulation factors and increases the aggregation activity of blood cellular elements. All this leads to spasms of the microcirculatory vessels and a complete cessation of blood flow, which may occur in the capillaries. This can cause the development of ischemic lesions in the tissues of the brain and heart. This mechanism may explain the existence of a correlation between the increase in cases of acute myocardial infarction and periods of increases in low-frequency components of SRs [119]. Is There a Cause-And-Effect Relationship Between the Human Body and the Electromagnetic Field of the Earth at Schumann Resonance Frequencies?
