This question already has an answer here:
Recently, a coworker brought up electro sensitivity as something to consider when developing new communications technology.
What little I have researched so far
The WHO claims that the majority of studies suggest it is a psychological disorder, with self proclaimed "sensitive" individuals being consistently unable to predict exposure.
Powerwatch UK claims it is still little understood and compares it to Photosensitive epilepsy.
Maybe a professional from a related field could clear up whether there is still reasonable doubt about the effects of EMF on health. Or in more simple terms: Is it a thing?
