I mean...no? I sometimes even sleep in my very very very EM noisy homelab (don't ask why, I'm just bad at managing my time haha) and never experienced any change from even when I'm in the woods. And when I say noisy, it's everything from radios, chunky power ICs under heavy load, inverters for my 36U server rack and the custom powerwall UPS back up they have... Well the 1-2U servers sound like jet engines and can sound like a nightmare, so the rack/enclosure is soundproofed but that shouldn't have any effect on RF emissions. The only pressure difference I feel when power is out is from the fear that my huge battery backup could fail to take over correctly. But that's mostly because it was a hand made, learn as you go type of system and I have very little confidence in my electronics skills. :'). I'd think that what you describe would be very easy to measure if it was more than a placebo effect. And there is a big corpus of research on the effects of EM noise. Wouldn't there be some sort of data on what you described by now?
