I found your response interesting. I surely don't expect to find Faraday cage air bnb listings.
I tolerate lower levels of electro magnetic radiation and personally limit use of wireless computers and cell phones.
Prior to the installation of a smart meter on my home of 20 years by Duke Energy, I did not in my wildest imagination think I could be so harmed and that a permanent condition would be created. In North Carolina, I had no rights as a property owner to have this meter removed; the utility company had the right to do whatever they wished. I had no choice but to sell my home and began the search for a safe low emf place to live. There are states which offer protection to persons with EMS by allowing us the right to opt-out of smart meters on our homes.

The development of this condition may be complex. Dr. Martin Pall in Portland, Oregon has done extensive research in this field and believes that there may be a 'genetic predisposition' to developing this. This may be a single allele dominant gene which when switched on creates an 'L gated calcium channel defect'. There is no treatment, only avoidance of the stimuli. If this holds to be true and you have a relative who is affected, you may wish to stock up on foil if that works for you.
