It might just be that I’m adjacent to Weird Health Twitter, but I keep coming across the idea that exposure to artificial electromagnetic fields (EMFs) may be harmful to health, or at least that they interact more with our bodies than we generally believe. I’m not going to write about whether or not I think this is true, because that would require a literature review and a refresh of some key concepts from my physics degree1, but I’m curious about my response to the idea itself.
