By studying the impact of solar activity on humans, Russian scientists have discovered that changes in the intensity of the geomagnetic field may be related to human gender formation. When the magnetic field strength weakens, the birth rate of boys is higher than the birth rate of girls, and vice versa. Scientists speculate that this may be related to changes in blood components, but further experimental confirmation is needed. This study reveals potential links between the geomagnetic field and biological processes, providing new directions for future research.
