### Earth's Magnetic Field and Schumann Resonance Frequencies: Origin and Essence
After performing numerous additional studies, it was experimentally determined that the exact frequency of the Earth is 7.83 Hz. Waves of this frequency are called Schumann waves. Schumann waves are standing electromagnetic waves of extremely low frequency in the atmosphere, the length of which approximately corresponds to the circumference of the Earth and is 38 thousand kilometers. They may have some variations in frequency (\(\pm\)0.2 Hz) and amplitude depending on the time of day, season and geography of the Earth's surface [43; 44]. Schumann waves propagate at the speed of light in the spherical layer between the Earth's surface and the lower ionosphere and circle the Earth approximately eight times per second. Therefore, in science, the frequency of 7.83 Hz was called the fundamental frequency of SRs, and a number of scientists began to call it the \"heartbeat frequency of the Earth\". In addition to the fundamental Schumann frequency, the plasmasphere has other resonant frequencies, which are also referred to as SRs. Today, eight ultra-low-frequency Schumann waves are known. Their rounded frequency values are 8 Hz, 14 Hz, 20 Hz, 26 Hz, 32 Hz, 39 Hz, 45 Hz and 50 Hz [38; 45]. The main source of waves for resonance and the occurrence of Schumann waves are various radio frequency bands that are formed as a result of lightning discharges in the Earth's atmosphere. At a given time, about two thousand thunderstorms occur on Earth: from 50 to 100 lightning strikes per second. The physical process of the formation of SRs can be described as follows. Lightning generates powerful electromagnetic radiation in almost the entire frequency range. But the \"Earth-ionosphere\" resonator from this \"white noise\" absorbs energy mainly at resonant frequencies due to the characteristics of its size. The plasmasphere receives constant energy pumping from lightning and converts all radiation into standing waves/solitons with Schumann resonance frequencies. Ultra-low-frequency waves (300 Hz-3 kHz) are received from the magnetosphere and ionosphere of the Earth's atmosphere in the form of so-called geomagnetic pulsations or ionospheric Alfven resonances that have no further influence along the geomagnetic field lines [35; 43; 44; 46; 47; 48; 49]. Thus, the Earth's magnetic field is formed through electromagnetic interactions between the Earth's surface and cosmic radiation. At the same time, the Earth's surface is under the constant influence of local atmospheric sources of electrical variations in lightning discharges and their result--SRs, which determine the contribution of the atmosphere to the local electrical landscape of the surface of planet Earth and influence living biological systems, including humans. Magnetoelectrochemical Theory of Metabolism as a Fundamental Theoretical Basis for Justifying the Interaction of the Human Body with the Magnetic Field of the Earth  
On planet Earth, the transfer of energy and information is also carried out using a magnetic field. But can the Earth's magnetic field affect the human body? What fundamental knowledge can justify the possibility of an influence of the Earth's magnetic field on the human body?The theoretical biophysical justification for the validity of this concept for the human body is the magnetoelectrochemical theory of metabolism (2019-2025) [3; 6; 7; 50]. This theory systematizes and extrapolates existing biophysical knowledge to the functioning of the human body at all hierarchical levels of its structure (from the subcellular level to the organismal level). The basic postulates were formulated [3; 6; 7; 50], which became the final substantiation of the fact that the human body, at the micro level of its structure, is formed by electromagnetic field structures. Data from the standard model were extrapolated to ideas about the structure of the human body, and it became obvious that the human body, like all atoms on planet Earth, is also formed by fermions, bosons, etc. [51].
