Science is nowhere near convinced that “WiFi allergies” are legit. It’s one of the first times a court of law has recognized EHS, or “electromagnetic hypersensitivity syndrome” — which is incredible, given that actual, hard evidence linking adverse health affects and WiFi signals is pretty negligible. EHS is, essentially, a grab-bag of physical symptoms with no known cause. Sufferers of EHS, estimated as “several” per million people, tend to experience some combination of physical symptoms like nausea, headaches, palpitations, fatigue and rashes/other dermatological problems, often at the same time.
