EMF from the earth/stray emf from return power?

In North America would you say there is EMF radiating out of the ground? For a bed canopy that is on ground level, would shielding be required over the floor, or is it likely that nothing is coming up out of the ground?

i havent measured a thing but ive been sitting/sleeping on a grounded copper mat since this crazy "outbreak" came about. i think it's helped immensely with inflammation issues. would be nice to figure out how the earth's natural field changes through time. it's not consistent.

That would be ground current.

Delta vs. Wye power distribution (since you asked about North America)

If you don't have an o-scope you can use a sensitive gauss meter to check for the presence of ground current in an area. Around 0.01mG would indicate very little ground current. You can compare readings indoors vs. outdoors since there are more potential sources of magnetic fields inside a home.

In my area there is a constant 0.3 - 0.4mG reading, whether in my home or walking around the neighborhood. When I tried sleeping under an EMF canopy I could not make it work for me. It would feel good initially bc I could feel the reduction of RF, but shortly after it would feel like it was concentrating other frequencies into my body. I even tried setting it up in the backyard because that was the only place where I could get 0 AC electric field, but it was just as bad. The real tip-off that the problem was ground current was when I attached the grounding cable to the canopy when it was setup outside. I was inundated with frequencies very quickly and I was kind of discombobulated the rest of the day. The cable isn't necessary when there are no AC electric fields to ground, but I wanted to see if it helped. It's a nice canopy too, made from the latest version of Blocsilver, but it won't work in this area for me. Might be willing to sell it if anyone here wants it. If you are sensitive to this the way I am then shielding the floor won't stop the canopy from catching the ground current frequencies.

so should we not be "earthing" or grounding ourselves?...or just not near high voltage equipment?

I think this is a good read. There's good discussion in the comments section as well.

I've tried grounding sheets and mats before I knew what ground current was. I always connected them to the earth outside and never the electrical ground in the house. I wanted to see what would happen if I stayed grounded as much as possible when at home. After a month I became very weak and fatigued. My joints would become noisy and my body felt heavy. I stopped grounding and everything returned to normal in 1-2 weeks. I repeated the experiment a couple more times in the following years, but it was always the same result. I wanted it to work because there is an initial positive calming and cooling effect on my body, but there were clear long term negative effects that were slower to manifest. Later on when I got a good gauss meter it made sense. I'll get an o-scope soon to see what's really going on in this area.

I still ground for shorter periods in the backyard while getting sun on my skin. This seems to be ok, but I'm always aware the earth isn't clean here. I wouldn't ground anymore than that unless I knew I had clean place to do it. Even if there are no high voltage lines nearby I think best practice is to measure what you can otherwise you don't know what you are conducting into your body.

Flux have you tried shielding with bio material.  I personally get a lot of benefit from sleeping with Twizzler 16-ounce packs taped together, 15 of them beneath my torso.  You can  interpose a mattres or foam topper. for best results, arc it over your torsoas well.

We have exactly the same problem where I live. There's a baseline ELF level of 0.4 mG in the entire neighborhood, and sleeping in a bed canopy only blocks higher frequencies (like AM/FM radio and GSM). I felt less burning but noticed other sensations more, and eventually i took it down.

I have read about "stray currents" killing dogs in the US. They are "barefoot" and makes them more susceptible it there is a problem with with stray currents. Owners were advised not to walk their dogs too near man holes, for instance, or make them wear small " boots" (!) Also, there has been problems on some farms where cows, who could not move away from their pen, got sick, and moved their legs in a strange way because of the discomfort.
