Humans seem to be more sensitive to be more sensitive to weak very high frequency field than what I have believed. According to research presented in academic dissertationSpontaneous movements of hands in gradients of weak VHF electromagnetic fields concludes that spontaneous hand movement reactions occurred as a response of the human body to the gradients of the VHF field intensity.
The reaction generally occurred in interference patterns of multipath propagation or standing waves originating from the radiation of FM radio and TV broadcasting transmitters and radiation reflected from the walls of buildings or from other objects. This non-thermal reaction was clearly observable as spontaneous arm movements by 39 percent of the 85 tested students. The most evident results were recorded near the buildings, where the radio waves reflected from the wall and patterns of standing waves were clear.
Experiments in a slow moving wagon and in a moving car showed a correlation between the test subjects’ hand movements and the intensity of below 1 mV/m radio and TV signals measured in the vicinity of the test subject.
