4 layers of Aluminium foil :-)) https://youtu.be/tVFJJEiJ1C0

During school some friends and I lived above our landlord who prohibited Wi-Fi, saying it gave him headaches. One time I accidentally used the Wi-Fi adapter for my Xbox 360, and he came up a half hour later with a sniffer demanding us to shut off the source. Never figured out if it actually caused him headaches, or if he just didn't want any sources on around him. He later moved to the middle of nowhere in West Virgina, and I remember reading a few months later about a community out there that surrounded themselves with a Faraday Cage.

Wonder if anyone ever told him about radio waves...or light in general.

EHS (electromagnetic hypersensitivity) has no scientific basis whatsoever. There have been blind studies that show no correlation between such exposure and supposed symptoms[0], so anyone with symptoms might only have a subconscious psychological response to knowledge of being around EMF.

There is the National Radio Quiet Zone [0] around the Green Bank Radio Observatory in West Virginia. But there isn't a giant Faraday Cage. That would be stupidly expensive to build. I met a few people who willingly moved to the area to get away from perceived RF radiation for health reasons. Transmitters aren't banned but they are highly regulated to run at limited power.

The same area is also popular with pot growers so you get an interesting mix of hippies, potheads, preppers, and people like your landlord.

Oh my the comments for that video are fun

I think that to efficiently block signals, the aluminum needs to be grounded? IE: Like a Faraday cage
