Have you ever noticed how, during a power out, suddenly there's suddenly a lack of ... "pressure" (lack of a better word) ? Context: I've experienced this and had a friend who experienced this as well. He told me and there was no power out yet that I could have used to ask other people about it. When I was digging for this through memory, it came up that this was always the case for me, during every power out. Addition: Contrary to what many people believe, electrosensibility is a real thing and when my mobile is too close to my head, down/uploading at high speeds (a few Mbit) I feel insane pressure in my head and trying this on other parts of my body the skin starts to feel like it's burning. I had a friend who didn't believe me, so I've offered him to do a test. He holds the phone, I close my eyes, he initiates a speedtest. I could tell him every time when he did. It baffled him.

This could be actual pressure, i.e. blood pressure related to the anxiety of your knowing your phone is emitting increased radiation.

  I am not sure how you meant it, but this radiation should abso-fking-lutely not be mixed up with nuclear radiation.

When the power goes out there's also a drop in background noise. Your fridge motor stops. Your fans turn off. You can hear the 60Hz (or 50Hz depending on where you live) line frequency hum from, for example, some light sources. In the olden days of CRTs, the flyback transformer could give a high-frequency sound. Normally your brain filters out that background noise. When it disappears, you can notice the change. As for your test with your friend, it's hard to know if you had good test conditions. It could be that the subtle sounds of motion to initiate the test gives a confounding signal. You should also measure the actual RF power generated by the phone during these tests. An FM transmitter can be at full power even when broadcasting silence. I don't know what phones are like ... do you?

  Also, don't forget infrasound - sound at frequencies too low to be audible. They are known to cause low levels of anxiety in sensitive individuals even though they can't be heard. > An FM transmitter can be at full power even when broadcasting silence. I don't know what phones are like ... do you? I dunno about 3G, 4G and 5G, but I know that a GSM phone (2G) after a data transfer continued to transmit, and at consecutively smaller levels before stopping. The time interval for each level was set by the telco, not the phone.

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?
