I don’t think that’s biology. Old CRT style TVs used to emit a really high pitch frequency, and from the ground floor, I could hear if the basement TV was on. With laptops, if it’s an older one or you have a bad power supply, you may be smelling ozone and that’d your queue, or if your room is small with little to no circulation, you may just be sensitive to the heat coming off it. As for the microwave, it may be faulty or ungrounded. If you were getting shocked by a running microwave, I do not think it would be like a static shock where you just get a little crack. They don’t deal with low power or voltage, it would be a concerning shock that you receive.
Is it just the slight vibration-type shock? I had a laundry dryer with a bad fuse be “live” one time, where if you touched it, you’d be getting shocked, but it was low voltage. But with the regular machine vibration and due to it not being a really powerful shock, it was hard to notice, plus like a microwave, when you pop the door, it largely turns off. The machine vibration coupled with the low power shock, I legitimately didn’t know it was shocking me for like…a few weeks. Because it was such a quick interaction with the machine, if you even touched it while it was on in the first place, it’d be hard to notice.


Concerning shock would be that you find it hard to let go; the current causes muscles to contract and your hand to close, and you actively have to make yourself let go. Appliances and household voltage can do so, but there is no mistaking it when it happens, and it’s not something you just brush off, especially if it happens repeatedly. And then why would you be the only one experiencing it?
I’d be having people recreate your conditions; if you open it early, length of time, close time proximity to when it occurs. What would you think the cause is, if not something similar to faulty appliance?
