I've been to Death Valley years ago & took a drive out into the remotest areas. it was fascinating experience, probably the quietest place I have ever been in the USA. There was nothing electrical anywhere near I was visiting.
Based on 1,000 of home evaluations -- we find that the internal sources of EMF are much higher than the external sources (uncontrollable) ones. I suggest you try turning off the electricity to your home at night -- or at least for a while during the day -- and feel the difference. Unless you live in a high-rise in an urban area, this simple task will make a huge difference.
In addition, the lower the floor the less exposure -- if you have a basement or at least the first floor will have less external sources.
