Just my €0.02: Electromagnetic Hypersensitivity is real; it’s just that it is extremely unlikely that it has anything to do with RF/EM emissions of any kind.
That being said,
(1) Massive RF/EM do have effects on organic tissue, i.e. humans. Which is why MRTs work, or why radio towers are switched off before the technicians climb up, why you don’t stick your head into an active microwave, have strict sefety rules around x-ray machines, and so on. There even is stuff like that research in Canada in which magnetic fields were found to trigger religious epiphanies in test subjects.
But these are massive fields with a lot of energy, several orders of magnitude above anything you’d encounter with WiFi or your cellphone, or basically anything you can lay your hands on outside special, restricted equipment.
(2) Humans have organs that can sense EM radiation - the bit of the spectrum known as visible light.
Birds can sense the Earth’s magnetic field.
Fish can sense and/or generate electrical fields.
It is conceivable that some humans can sense RF/RM outside the usual spectrum.
(3) When people suffer from something, they suffer. Whether it’s from something “real”, i.e. measurable and quantifiable, or not. And a civilized society should at least try to alleviate suffering.
