Schumann resonances (SR) are global electromagnetic resonances generated by lightning in the cavity between the Earth’s surface and the ionosphere. Their existence was predicted mathematically in 1952. However, it took another decade before they could be reliably measured and verified. Given that Schumann resonances occur in the same electromagnetic frequency spectrum as human brain waves, it has been suggested that extreme fluctuations in these resonances could affect human behavior and health.
