>>106020670 (OP)I think it's a meme.
So for example, you ever see that video where someone was able to pull am radio signals off of grounding wire in a house?
For one, you probably don't want that, which for efficacys sake would require you run a separate shielded ground wire in your house, which is not impossible, but very difficult by most people's standards.
One other thing which other anon mentioned is that you can basically make a very big antenna to sit on. Personally I find having my phone (5g) in my pocket/ sitting near a wifi extender far more irritating than not being grounded generally speaking. In short, a faraday shield would be useful. Silver fiber engineered fabric bed tents are expensive. If it matters, then it would be worth it buying the fabric yourself and making your own tent, it would cost about half as much, still hundreds of dollars. Once these problems are addressed then we can talk about hooking your bed up to ground.
It is important to note, that if you are emf sensitive, avoid bedsprings, or mattresses with internal springs, or metal bedframes. Protip, if you like firm mattresses, try a French mattress.
With all that said, the science is there, you don't want an accumulation of static electricity in the body, it causes inflammation.
