There may be magnetic particles present in our bodies.
According to one theory, nanocrystals of magnetite (Fe3O4) are present in some tissues of the human body, including the brain, which are believed to have been used by our ancestors as a kind of 'internal compass.'
Changes in the magnetic field affect these particles, causing irritation of receptors and brain structures, which leads to a state similar to stress.
Another theory emphasizes that many processes in the body, such as the generation and transmission of nerve impulses, are, from a physical standpoint, electrical currents that interact with the Earth's magnetic field.
