Schumann wave Generator 1. wave electromagnetic wave is extremely low frequency, can penetrate any substance, is non- radiation.2. wave is a natural energy source, and it is inexhaustible. Anyone who is easy to resonate with wave is always obtain energy, and the natural spirit is full and healthy.3. Through the resonance of the accepted wave electromagnetic field and the cell frequency of the human body, the overall balance of the human meridian is maintained, thereby reducing the damage caused by EMF radiation.4. When the natural regenerative magnetic field is simulated by electronic means, such as using a square wave generator to generate an artificial 7.83 Hz wave frequency instead of a natural wave.5. The generator can induce human body frequency resonance, supplement natural geomagnetism and artificially weaken electromagnetic field EMF interference, and make cell membrane potential balance health. 1. wave electromagnetic wave is extremely low frequency, can penetrate any substance, is non- radiation. 2. wave is a natural energy source, and it is inexhaustible.
