Electromagnetic hypersensitivity is an illness in which exposure to electromagnetic radiation can produce a variety of physical symptoms. In most towns and cities, current levels of this radiation are more than a million times higher than previous levels under which life has evolved. People who are chronically exposed or have some other inciting event, or both, may become severely electrosensitive, thus becoming deprived of safe access to much of their surroundings. The immediate physical consequences of this malady can be devastating, and the secondary psychological challenges often are just as dire. This N = 1 study by a physician with severe electromagnetic hypersensitivity describes the "underworld journey" of a person suffering from this illness.
