There are a small group of people existing in the world who are allergic to radio. When they are exposed themselves in radio, they will feel headache, arrhythmia, insomnia, even apoplexy. This ill is called EHS (Electromagnetic Hypersensitivity).

He says, “The room is completely insulated; the edges are sealed with aluminium tape and connected with conducting tape so I could ground the whole room. It’s a Faraday cage, effectively. Grounding helps with the low frequencies radiation, apparently. The high frequencies just bounce off the outside.”

Because of its vast size and sophisticated design, the GBT is exquisitely sensitive to even the faintest radio pulses coming from space. For the same reason, it is also extremely susceptible to electronic interference. Any device that generates electromagnetic radiation—a cell phone, a television, a wireless Internet router—can skew its data. And so the people who live in these parts must, by law, forego some of the gadgets that most of us take for granted.

Some people, even experts say that it is not a real disease, but just a mental disorder.

Dr. James Rubin from Kings College London did series of studies to prove it is a psychological condition.

Some experiments shoes that those who are self-described with EHS report adverse reactions to electromagnetic fields at intensities well below the maximum levels permitted by international radiation safety standards. The majority of provocation trials to date have found that such claimants are unable to distinguish between exposure and non-exposure to electromagnetic fields.

This new kind of disease is difficult for many people to understand, some patients are therefore isolated from their families, and even be treated as a mental patient.
