The affect is caused by capacitive coupling from element to recumbent target and from there via body contact to ground. The magnitude of the tingle depends on the coupling capacitance. When measuring with a meter the meter forms the lower leg of an impedance divider from element via Ccoupling to body and then via meter to ground. A higher impedance meter will give a value closer to mains voltage than a lower impedance meter. Blanket instructions (which most ignore) say not to have blanket powered on when a person is in bed. Leaving a blanket on high while sleeping will convince you that you NEVER want to do it again. HOT!!!.
