It's a recognised condition, yes. But not in any way linked to electromagnetic fields. That is proven by the fact that the symptoms depend not on how much the sufferer is exposed to EM fields but on how much the sufferer believes they're exposed to EM fields. If they're told they're exposed and they believe it, they show symptoms. Even when they're not being exposed at all. Here, for example, is the WHO position: https://www.who.int/peh-emf/publications/facts/fs296/en/ I'll quote the most relevant part so you don't have to read it: I think that the first one is being generous because it doesn't account for the studies in which the conditions were identical and the symptoms of EHS depended solely on what the sufferer believed regarding the presence of EM fields. Not only is there no evidence of causation between EM fields expsure and EHS symptoms and no possible explanation of how causation could occur, there isn't even correlation. It's not just that it isn't proven true. It's proven false.
