But while scientific evidence supporting the condition's existence is weak, some scientists say, the studies may not be definitive.
Dr. David O. Carpenter, director of the Institute for Health and the Environment at the University of Albany in New York, said that while science indicates that electromagnetic fields have a number of effects on the nervous system, the question surrounding electromagnetic hypersensitivity is debatable.
He said that because patients report such a wide range of symptoms, both in terms of how and when they manifest, more studies are needed that take that variation into account. Some people may respond immediately to electromagnetic waves, others may not experience the onset of symptoms until later.
"In my judgment, I think that there's so much anecdotal evidence for real human suffering in these people that have this EMF sensitivity," Carpenter said. "It seems unlikely to me that it is just a psychological thing. But I am also a scientist and expect that there should be good proof if it does exist."
