EMF from wifi sees like a sus root cause for the claimed issues. It’s very low energy. I’ll have to dive into it.. 2.4GHz is nicely tuned to interact with water, so not the DNA directly. Are there any bonds in DNA that respond strongly to 2.4GHz? Or maybe the idea is that hot water molecules collide with DNA and damage it?
