There is a dedicated group of people who believe any electromagnetic emission is affecting them negatively. Searching on "electromagnetic free zones" is quite the rabbit hole. And there's way more to them than the "5G is mind control forced on us by the Illuminati for the New World Order" crowd.
They definitely should not own one of these then: https://somasynths.com/ether/. But it is lots of fun for me.
I met a new age architecture consultant (not an actual architect) back in the 90s that was convinced his bag of Epsom salts and a copper spring was protecting him from the cancer causing electromagnetic fields produced by house wiring.
The Parkes radio telescope had issues with fast radio bursts that they couldn't attribute to what they were tracking. Turned out to be a microwave oven in a nearby building where the door was opened before it had stopped.
While I wouldn't subscribe to standing in front will cook you idea, opening the door prematurely does give off radiation. Standing in front of a microwave beam dish may be a different story - knew an ex-Telecom tech who told a possibly tall tale of cooking chicken.

The Telecom guy might have been pulling your leg, but microwave dishes are known to be dangerous if you're in the wrong spot in front of them. (The traditional story is that Percy Spencer noticed a chocolate bar in his pocket get melted by the radar set he was working on. However, the effect had been demonstrated at least a decade earlier.)
What's funny is that you can make a defensible argument that COVID caused 5G.
(Basically, everyone was even more chronically online during the lockdowns, so there was extra money to be made and extra urgency in rolling out telecommunications infrastructure.)
