Schumann Resonance 7.83Hz: Harmonic Resonance "It has long been suspected that human consciousness can impact the magnetic field of the earth. As far back as we know, the Earth’s electromagnetic field has been protecting all living things with this natural frequency pulsation of 7.83 Hz. You can think of this as the earth’s heartbeat. The ancient Indian Rishis referred to this as OHM, or the incarnation of pure sound. Whether by coincidence or not, the frequency of 7.83 Hz also happens to be a very powerful frequency used with brain wave entrainment as it’s associated with low levels of alpha and the upper range of theta brain wave states. This frequency has also been associated with high levels of hypnotizability, suggestibility, meditation, and increased HGH (human growth hormone) levels, in addition to increased cerebral blood-flow levels while this frequency is being stimulated. It would seem then that our nervous system can be influenced by the earth’s electromagnetic field. Maybe that’s why being in nature has always been so restorative and healing. Disconnecting from a typical city setting by reducing our exposure to crowds, traffic, work, and routine life—and instead getting out in natural surroundings—can slow our brain waves down from the aggressive, vigilant, anxious, and impatient states that are seen in higher ranges of beta brain waves to more restorative alpha waves."
