I find the EHS definition on wikipedia outdated:
https://en.wikipedia.org/wiki/Electromagnetic_hypersensitivityIf anyone has info, I think we should collaborate to find evidence based information to improve this page. All it says is the condition is entirely in the mind.
Sweden has recognized this condition already, and that's not mentioned there at all. I am sure other advances in testing have been done too. I have found research by Dr. Magda Havas that has found an immediate reaction to wireless radiation. I'm not sure if it qualifies, and if it's double blind etc. But at least a small start with Sweden would be nice.
This Popular Science article
http://www.popsci.com/science/article/2010-02/disconnectedtalks about an engineer at Ericsson that literally falls to the ground if a phone rings next to him. Does this not qualify for showing that there are indeed people who can 'feel' something?
