Using Coulomb deep field technology,a resonant energy wave with the same frequency as cellmovement is generated. lt is in contact with the human footthrough a pair of foot electrode plates. Through the acupoints,meridians, and blood vessels on the foot, a resonant energy wave with alternating magneticand electricfields is introduced into the human body fluids, blood, tissues, and eight major systems causing polarization and oscillation of the cells and bloodmolecules in the human tissue, generating deep autonomousheat.The whole body's capillaries expand and sweat as a whole.
