Man of Honour
EMS is a recognised condition in some jurisdictions, including at law, and for insurance risk assessment, and wrt actions to be taken by employers to mitigate risk.
German medical research suggests - If I recall correctly - the problematic wave frequency is in the beta band.
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:
Well controlled and conducted double-blind studies have shown that symptoms were not correlated with EMF exposure.
It has been suggested that symptoms experienced by some EHS individuals might arise from environmental factors unrelated to EMF. Examples may include “flicker” from fluorescent lights, glare and other visual problems with VDUs, and poor ergonomic design of computer workstations. Other factors that may play a role include poor indoor air quality or stress in the workplace or living environment.
There are also some indications that these symptoms may be due to pre-existing psychiatric conditions as well as stress reactions as a result of worrying about EMF health effects, rather than the EMF exposure itself.
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.
