More woo. https://en.wikipedia.org/wiki/Electromagnetic_hypersensitivity

Whether it is imaginary or not is debatable at best. It is not particularly accepted as a diagnosis, and there are some humorous examples of people who cannot demonstrate their sensitivity. i.e. they can be isolated from exposure and they don't know it. In one case, a town complained about the effects from a nearby cell tower, even though it had been turned off for 6 weeks.

There may be other conditions yielding the professed symptoms, but "electromagnetic sensitivity" is utter garbage.

who have done things like sue their neighbors because of neighbors' cell phones. They keep on getting far too much consideration from the courts.

I read something recently that named famous people with electrosensitivity, and Ben Franklin was one names. Really? In an era before we had all these electrical things in the air?

This is right up there with Mogollon's disease. People who are nutty try to convince others they have some real-world disease.
