We must first understand that our biology is intrinsically in sync with nature. Any unnatural form of energy which is not congruent to our well-being and growth is considered harmful.

The body and brain require earth’s frequency of 7.83hz for the mental and physical body to be healthy. Dr. Herbert Konig showed the connection between 7.83hz and the brain rhythm. EEG recordings of the natural electromagnetic fields in the environment coincide with the alpha brainwave. This is the brain wave rhythm of all mammals in the rested, balanced state.
