Cellular structures such as humans act as antennas to microwaves. As the waves hit, small electrical currents are excited and go to ground through any possible path, with a magnitude in inverse proportion to the path's impedance. Hormones, antibodies, and neurotransmitters work along electrochemical pathways through ion exchanges, regulating synaptic voltage potentials and neuron firings. The grounding of extraneous microwavegenerated currents disrupt the 86 billion sites of such millivolt activity in the human body and accumulate as system noise.
