There is debate as to whether this is true, but if so, then it lends much weight to my theories below on just how much Schumann Resonance and electromagnetics have an effect on the human body and mind.
In 1962, the National Bureau of Standards division' of Radio Propagation reported the actual physical detection and instrumental recordings of these signals; and as predicted, tracings were indistinguishable from human brain waves.
Unfortunately, very little is publicly known about this biological signal, although NASA has been using this knowledge to protect astronauts while they are outside the earth's natural source. The physical condition of early astronauts deteriorated severely while in outer space, away from the Schumann Resonance. The problem was solved by introducing the 'Schumann Simulator' into all space shuttles, a magnetic pulse generator mimicking the Earth's frequency. This demonstrates the simple fact that we cannot be healthy if disconnected from the "natural biological frequency." Mike Korell
How is that for interesting? This familiar resonance pattern works at affecting our moods and well-being. I found it very interesting that NASA actually created a device that can mimic the Earth's frequency to keep astronauts in a good state of mind.
