I've been dealing with poor sleep for quite awhile (over a year) and one of my suspicions is EMF interference in my room. I've tried unplugging everything at night, but didn't notice a significant difference, so I suspect it's coming from some other source, perhaps one I'm not aware of (e.g. the wifi router in the other room).
How should I go about testing my suspicion?
For example, is there a device you recommend that will give me useful readings? If you had similar issues, was there a strategy / product / solution that worked well for you?
That's the kind of information I hoped to find here more than in electronics.se. I beg to differ only because while the title mentions electronics (tools), the overall context / concern / application is around health.
I spoke to a specialist in EMF health and asked which of the devices are more useful and tend to help most in detecting potential health issues. The specialist said the voltmeter was less useful than the Gaussmeter, and that some ranges of radio frequencies impact human biology more than others.
