There’s no such thing as proof outside of mathematics and philosophy. The fact that a couple of studies found a link between phone placement and sperm counts is by no means “scientific proof,” because scientific proof doesn’t really exist, only increasing magnitudes of evidence. This is because of sampling and certainty and falsifiability of scientific hypotheses and a million other things.
A better way to word such statements would be “there is ample evidence to suggest that, for a man, keeping a cell phone in one’s pocket leads to a decrease in sperm count.” “Scientifically/clinically proven” may wash well in the pub, but it makes science philosophy-savvy types cringe. It’s usually a red flag for bullshit, and best avoided.
In any event, I’m interested in the legitimacy of “EMF toxicity.” I agree that it’s best to turn off routers at night, especially if you have kids in the house — there are lots of extant concerns about EM radiation causing protein misfolding, which could lead to all sorts of problems including those mentioned. But is there any evidence to suggest that within-standards exposure over the long-term causes tinnitus, for example?
The easier explanation for the headache/tinnitus/anxiety trifecta is that the anxiety could be causing prolonged muscle tension in the head and neck, leading to headaches and straining at the temporomandibular joint/accumulation of lactate and inflammatory mediators that might be producing the tinnitus.
Again, I’m not saying that EM hypersensitivity isn’t a thing or that there aren’t unaddressed problems with the ubiquity of these devices in our lives, but I’d like to see a plausible causal hypothesis before I impale my router and flee to the hills.
