Natural PEMF comes from more than 7 million lightning bolts that strike the Earth every day.
These flashes of energy from above resonate and ring the proverbial bell of the ionosphere to an average note of 7.83 Hz, also known as the Schumann Resonance (and the first Chakra).
Our bodies have been exposed to and resonate at these natural low Earth frequencies since people have been around on planet Earth.
There are 7 Chakras that serve as convergence energy points (or Nodes) named the Crown, Brow (or Third Eye), Throat, Heart, Solar Plexus, Spleen, and Root that correspond exactly to the seven main nerve ganglia which emanate from the spinal column.
These Chakras are energized by the Schumann Resonance and its first 6 harmonics (multiples) to which our bodies are accustomed.
The sHEALy-Sorin Gamma PEMF device sweeps all those natural frequencies from 5.83 Hz through 56.83 Hz with Pulsed Electro Magnetic Field signals with other modes of operation (Gamma and Delta) selectable.
