Got the house WiFi on a timer to go off from 1-6 AM. Gonna see how long it takes my parents to notice

The EMF-phobes have plausible arguments and I'm down to entertain the ideas

But everything I've tested I can't tell a difference at all.

Wired/bluetooth headphones

Grounded bed

Cellphone near balls

No perceived difference. Maybe there is an effect but it's on a longer timescale and a subtler effect than I can observe

But at that effect size your time is better spent elsewhere (even NGAF would probably be better BC not stressing over it)
