Can you really be allergic to Wi-Fi?

Would be quite something if more people became allergic to Wi-Fi. It would mean people would actually be forced to talk to each other again.

Recently there have been multiple reports of people having recurring headaches, nausea, dizziness and skin irritation as a result of a sensitivity to electromagnetic field sources, a condition otherwise knowns as electromagnetic hypersensitivity (EHS). Whenever people who suffer from EHS are around devices that emit electromagnetic signals (such as cellphones, computers, or Wi-Fi stations). According to a survey people's symptoms were lessened when they weren't around such devices. Yet, could this be a real thing?

Symptoms are often the same as with other diseases

Several people in scientific community are highly sceptical of EHS. A review of multiple scientifically controlled studies states that people who were asked to determine when a Wi-Fi signal was turned on (perhaps unsurprisingly) were unable to to tell the difference.
One of the authors of the review, Dr. James Rubin said that the people who say they have EHS really are ill, but the science has strongly suggested that it isn't electromagnetic signalling which is causing the symptoms. The symptoms of EHS are of a wide variety, but a very generalised. Headaches could be a symptom of a cold or that you've had too much sugar. Nausea could be a sign that you're coming down with the flu or perhaps even a(n) (allergic) reaction to something you ate. As of yet EHS is not recognised as an official medical condition.

People could be reacting to the 'nocebo' effect

In a paper by Dr. Rubin the symptoms of EHS patients and their possible triggers were analysed. Rubin stated that "repeated experiments have been unable to replicate this phenomenon under controlled conditions." According to Rubin it could be that Wi-Fi is the reason for the patients' suffering, but that it's very possibly something else entirely as well. Things such as influences on a person's health and their environment could be responsible.

Another reason could be that people are reacting to a "nocebo effect" where the person believes that electromagnetic frequencies are causing their symptoms, making them appear. It's the same as how certain people can think themselves sick, I used to be really good at that when I was a kid. Whatever the outcome of the past studies, the suffering of the patients is real, and it is vital that we learn more about what is causing their pain.
