NASA and the Schumann Resonance
The Schumann Resonance is the Earth’s natural electromagnetic frequency—about 7.83 Hz—and our bodies are wired to it. This gentle rhythm helps regulate our stress response, mood, sleep, and overall sense of balance.
​
When astronauts left Earth’s magnetic environment, NASA discovered they experienced fatigue and disorientation without this stabilizing frequency. To keep them healthy, NASA now replicates the Schumann Resonance in spacecraft. PEMF mats use similar Earth-like frequencies to help the body feel grounded, calm, and better regulated in our modern, high-stress world.
PEMF Frequencies:
