Are Wi-Fi Allergies Real?

For some time now, people with unexplained and recurring headaches, dizziness and skin irritation have been blaming their often severe discomfort on sensitivity to electromagnetic field sources, a condition sometimes called electromagnetic hypersensitivity (EHS), according to the World Health Organization (WHO). In a recent case, the family of a 15-year-old girl in the United Kingdom who died by suicide said the girl had suffered from an allergy to Wi-Fi signals. The signals at her school made her nauseated, gave her blinding headaches and made it difficult for her to concentrate, the teen's mother said in a U.K. court on Nov. 19, according to a news story about the case in the U.K. newspaper The Daily Mirror. Participants in a survey of people claiming to be suffering from EHS described physical symptoms such as headache and fatigue that appeared whenever they were close to devices that emit electromagnetic signals, such as Wi-Fi stations, cellphones and computer screens. Removing or insulating themselves from the signals alleviated their symptoms, according to the survey findings. However, scientifically controlled tests in which people were exposed to electromagnetic signals but were not told when the signals were turned on or off overwhelmingly showed that study participants were unable to determine when the signals were present, according to a 2009 review of 46 such studies published in the journal Bioelectromagnetics. What about the symptoms? "People who say t...
