How does the schumann resonance affect humans?
Schumann resonance is an extremely low-frequency electromagnetic wave existing between the Earth’s ionosphere and the surface. Its fundamental frequency is 7.83 Hertz, and the amplitude range is between 0.1 and 1 petesler. Since it was first theoretically predicted by the German physicist Winfried Schumann in 1952, it has become an important phenomenon in geophysics. According …
