https://www.sciencedirect.com/science/ar... Here's the actual article. The RF is what would come from your wifi, ELF-MF is what would come from the AC current in your walls. Good-ish news on the RF side of things is that it seems that it's just the tablets (with or without internet connectivity) that are shown to be dangerous devices (by this study, at least); cell phones showed no increased risks. I'm also a bit curious about why ELF-MF is so much higher in Mexico City (where the study was conducted) than global average. Interestingly, wifi and Bluetooth headphones are never mentioned.

It's actually both, although the biological effects are different. The higher frequency RF has resonant effects at the molecular level. That's the concern with 5G as it has resonant frequency influences on water molecules (like a microwave oven). The low frequency EF influences higher level biological processes.

earth loops. earth loops (ie, more than one earth inside a house circuit) dramatically increases the ambient EMF. that EMF penetrates easily inside your body and reduces sleep depth. there is the main cause of the problem: retarding your immune system. i inadvertently caused this situation for myself in a house in rural Madeira 6 months ago. on top of difficult housemates my stress levels got so high i was ready to just plop myself down in belgrade and see what i can see. fortunately, a friend with property in croatia suggested i go there. i've been rebuilding myself ever since. oscillating magnetic fields are toxic to life no matter what. the reason why the big screen is a problem is because it's a giant high frequency radio that at operating distance is doing the same thing. one of the occupational hazards of being a computer programmer...
