Neighbors faces: Give them a few links where they can study on their own. Don't be surprised if people behave narrow mindedly.
Make sure all your other EMF concerns are fixed (switchmode circuitry in LED/fluorescent bulbs, fans, monitors, power cables, wireless stuff, etc)
Look at all your nearby smart meters. Which direction are they pointing? If away from you, then they should have a metal box or plate between you and the meter. But still the entire house is resonating somewhat.
Meters are rated to communicate wirelessly in worst case scenarios at 600 feet, which means they can send an unintelligible carrier signal 3000 ft -- to be skeptical or safe -- the signals are strong.
Living in a remote area off-grid is best, but then you can get cabin fever :)
Shielding can be tested with a Faraday cage. Foil can be placed between you and the smartmeter, but don't reflect another meeter from another angle! Pre shielding analysis is difficult.

A meter 100 ft away can have an impact, and usually there are several. I noticed anger, anxiety and slight vertigo, before I shielded, yet luckily the related house was bought and the new owner moved the meter to the opposite side of his house facing away from me. Still I cannot sleep without a shielding cocoon. I plan on much more shielding with copper foil and aluminum foil. I appear completely un-PC, and work to conceal that -- but sound sleep, sanity and health is an ever present need.
There is a study online (forgot the source) that experiments with a small Faraday cage of aluminum foil. The slightest separation in the seams, causes EMF to enter the cage via resonance through the seams. So I have noticed over more than a year of observations, that my cocoon must reach over my head by two feet so that I can flop that extension together as a pillow and completely seal the cocoon, otherwise, I get nervous leg syndrome. I have a small breathing vent area, but plan on a metal mesh there.
Even without those seam concerns, and used roughly, however, the Faraday cocoon is a blessing.
