Specification AgeRangeDescription : Kid Brand : IUPPA BulletPoint1 : This product is a 7.83 Hz low frequency Schumann s featuring high accuracy and stability. BulletPoint2 : Schumann electromagnetic s are low frequency and can penetrate any material. BulletPoint3 : Each individual has a network of weak currents that will duce frequency resonances when excited by Schumann s. BulletPoint4 : The overall equilibrium of the human meridians is maintained by receiving the Schumann electromagnetic field and the cellular frequency resonance of the human body to reduce the damage caused to the human body by the EMF ionizing radiation. BulletPoint5 : Human frequency resonances can be induced, complementing natural geomagnetic and artificially attenuated electromagnetic field (EMF) interference, and equilibrating the membrane ential fitness.
