The existence of an organism is possible solely due to the close connection and coordinated functioning of the tissues of its organs and the systems of the whole organism. It is important to understand that this consistency is realized thanks to numerous oscillatory processes that occur at different levels of the structure of the body's vital systems [3; 6; 7; 53; 54; 55; 59]. The body is a self-oscillating nonlinear system. Various types of vibrations occur simultaneously in the human body: mechanical, electrical, acoustic, etc. In this case, the excitation of one type of vibration can cause the excitation of others. For example, the propagation of a nerve impulse leads to the mechanical contraction of muscle cells. Oscillatory processes in the human body can have an informational component and be part of systemic information processes. Thanks to this, the human body can transmit one signal to another, perceive vibration information of all types and react and adapt to changes in the external environment. An example is heart rate, the variability in which conveys information about the functional state of the body [137; 138; 142; 143]. This idea implies the presence in the human body of a reaction system based on the principle of resonance with a nonlinear limitation of the increase in oscillations and with feedback between the energy source and the resonator. This requires continued research and is still under debate. Almost all cells of the human body's organs come into contact with blood. Blood is a magnetically saturated medium that exhibits magnetic properties [122]. Blood contains red blood cells and hemoglobin, which contains iron atoms with non-zero magnetic moments. Therefore, Schumann resonances can affect the blood, changing the transport and distribution of ions and their membrane transport [122]. Accordingly, this will change the processes of electromagnetic generation in the membrane structures of cells, influence the depolarization of membranes and change the electrical potential of cells. It was found that in erythrocytes with membranes exposed to an electromagnetic field, changes in the transport of potassium and sodium ions occurred, and a decrease in electrical mobility and an increase in membrane permeability were recorded. In this case, their aggregation was activated. It has been proven that, due to the parallel orientation of the magnetic moments, the spontaneous magnetization of an array of particles causes the appearance of groups of particles with an ordered packing. Such a group, when moving in the vascular bed, can exhibit the behavior of a soliton-like object [144; 145; 146]. The observation of the reversible aggregation of erythrocytes can be explained by the formation of similar objects in the bloodstream. Blood plasma contains a large number of ions and has the property of electrical conductivity. Electrical currents that are induced by moving red blood cells can cause increased plasma circulation around them and around each red blood cell. It is important that when red blood cells move, the magnetic field changes, and, in accordance with the law of electromagnetic induction, electric currents arise that tend to compensate for changes in the magnetic flux. The functions of many organs of the human body involve the passage of significant amounts of blood. Therefore, theoretically, this mechanism can influence their general electromagnetic state and responses to influences. Studies [147; 148] have confirmed the existence of the human magnetic sense, which is supposedly based on the quantum mechanical mechanism of magnetoreception. It has been proven that light-dependent magnetic orientation in humans occurs due to the resonant mechanism of the magnetic field. In one study, participants' magnetic orientation varied depending on the wavelength of incident light and was found to be dependent on blue light. It was concluded that these reactions could be mediated by a mechanism that is determined by the resonance of the magnetic field.
