### Earth's Magnetic Field and Schumann Resonance Frequencies: Origin and Essence
Thus, the human body, formed by electromagnetic structures, functions and lives thanks to the occurrence of magnetoelectrochemical processes within it. When considering the human body from the perspective of modern biophysical knowledge, it becomes obvious that man is integrated into the general system of life and into energy exchange on planet Earth. Therefore, from the position of the concepts of the magnetoelectrochemical theory of metabolism, the human body at all levels of its hierarchical structure can be susceptible to the influence of the Earth's electromagnetic field, since, in essence, it is formed by electromagnetic field structures at the micro level of its structure. The Concept of Synchronization of the Human Body and the Earth's Magnetic Field in the Schumann Resonance Frequency Spectrum  
If we consider all the existing and scientifically proven facts of the electromagnetic aspects of the structure and functioning of the human body, then ideas about its possible synchronization with the Earth's magnetic field appear quite logical. Should everything in nature have a biological meaning? What biological meaning could there be in synchronizing the human body with the Earth's magnetic field? It should be noted that the phenomenon of the synchronization of processes is a universal phenomenon in biology. Synchronization is observed in many living biological systems [63]. From a physical point of view, synchronization is a process of interconnection and mutual influence between objects/systems that fluctuate in time with a fixed phase relationship between them. That is, there must be some connection between objects leading to synchronization, as was, for example, established during the discovery of the phenomenon of synchronization in the 17 th century by [PERSON] (1629-1695) in an experiment with the pendulums of two clocks [64]. The oscillations of the pendulums of mechanical watches gradually became synchronized due to weak vibrations that were transmitted through a common support from one watch to another. The phenomenon of biological synchronization is an important mechanism of self-organization in complex systems. Due to interaction with the environment or the interaction of subsystems, this makes it possible to significantly reduce the degree of freedom of the biological system. The classical theory of synchronization uses the concept of the existence of an autonomous periodic generator. According to this scientific concept, if an external periodic force of the appropriate amplitude and frequency is applied to an autonomous generator, then this system will oscillate in phase with the external signal. Therefore, synchronization can be classified into frequency synchronization and phase synchronization [65; 66]. If we theoretically consider the interaction of the electromagnetic field structures/processes of the human body with the electromagnetic field of the Earth, then we can postulate that during evolution, the human body adapted to become phase synchronized with the background electric fields of the atmosphere, the frequency characteristics of which were predetermined by SRs. In other words, SRs should be the natural factor through which the mechanism of the electromagnetic influence of the planet Earth on the course of magnetoelectrochemical metabolic processes in the human body is realized. The logic of this conclusion is based on the following knowledge. Theoretically, the phenomenon of Schumann resonance has existed on planet Earth for billions of years, since the appearance of volcanic and thunderstorm activity. In the process of evolution, this maintained a natural background field of extremely low frequencies throughout the planet, with a certain maximum frequency with a fundamental mode around 8 Hz (as now proven and understood by science) [67]. The magnetic fields of the Earth are naturally conductive to the existence of biological life [68]. It is logical that during evolution, especially in its early stages, SRs were the only constant electromagnetic fields available for such synchronization.
