Nikola Tesla, the world number one inventor in field of electricity, who discovered both alternative current practical potential and wireless communication principles, seems to be also the first ever victim of electrosensitivity (electrohypersensitivity, electromagnetic hypersensitivity).
This medical condition, when people suffer due to electromagnetic exposure has been described in details by Dr. Olle Johansson from Karolinska Institute, Sweden [1]. Typically people have skin and mucosa related symptoms (itching, smarting, pain, heat sensation), or heart and nervous system disorders after exposure to computer monitors, cell phones and other electromagnetic devices. Also, fatigue, irritation, headache, sleep disorders, hormonal imbalances and even low sex drive were detected in people living in increased levels of radiofrequency radiation, e.g. nearby cell phone base transceiver stations [2, 3]. By the way, in Sweden electrosensitivity is officially recognized medical condition.
In the case of Nikola Tesla, as it was described in his biography written by his friend John O’Neill, he suffered hypersensitivity greatly in his later years: ” One of the symptoms of the illness was an acute sensitivity of all the sense-organs. His senses had always been extremely keen, but this sensitivity was now so tremendously exaggerated that the effects were a form of torture. The ticking of a watch three rooms away sounded like the beat of hammers on an anvil. The vibration of ordinary city traffic, when transmitted through a chair or bench, pounded through his body. It was necessary to place the legs of his bed on rubber pads to eliminate the vibrations. Ordinary speech sounded like thunderous pandemonium. The slightest touch had the mental effect of a tremendous blow. A beam of sunlight shining on him produced the effect of an internal explosion. The strange manifestations he exhibited attracted the attention of a renowned physician, who declared that medical science could do nothing to aid him.”
