Can you really be allergic to wi-fi? The condition is sometimes called electromagnetic hypersensitivity (EHS), and the symptoms range from fatigue and physical pain to rashes and eye discomfort.

The discussion of electromagnetic hypersensitivity came back into public consciousness after a 15 year old girl from the UK committed suicide, with her mother citing a rare wi-fi allergy as the cause. Though her family had taken wi-fi out of their home, the signals at school were keeping her ill, her mother says.

Electromagnetic hypersensitivity is disputed, though scientists don't question the reality of the sufferer's symptoms—the symptoms are just not that of a wi-fi allergy. Researches say that these symptoms are usually "very generalized, meaning they could have many causes," and the World Health Organization notes that "EHS is not a medical diagnosis."

“People who say they have EHS are clearly ill,” Dr. James Rubin, the author of a 2009 review on EHS, told Live Science. “But the science suggests that it isn’t [electromagnetic signaling] that is causing the illness."

Rubin's report concluded that the symptoms of EHS were unable to be replicated during controlled experiments, throughout multiple attempts.

In other wi-fi news, one waste management company in New York City has started installing garage cans that provide free wi-fi access.

Most definitly not a real thing. The symptoms are too general and not replicable. Probably stress or perhaps nocebo (but even this sounds like a strech, as it has been shown our brains cannot detect the presence of wife, so people would only have symptoms when they know the wife is there before hand, which could be easily tested).

Light is more unhealthy for the body than wifi signals, so no

I remember an incident, when people suddenly started complaining about EHS, Wifi allergies, etc when a big antenna and mobile phone array was placed on their appartment building. Made a real big fuss about it to.

Funny thing was, the array was not hooked up to anything at all during that time.
