https://www.ncbi.nlm.nih.gov/pubmed/18568931/ This one pretty much, and thtat first link above... I did not realise that so much substantial research had been done. EMF from AC power raises blood glucose levels!
I want to live in a house with DC power now, and no radio transmitters of any kind inside.
Actually, that reminds me of something. In my little bit of reading I did in response to your reply, I read somewhere that certain types of tesla coils, that are tuned differently from the lightning machine type, that does not cause sparks, emits some kind of radiation, I think possibly it could be something in the range of cosmic rays, cause benefits to health. Also, there was mention that certain kinds of EMF exposure are therapeutic in one of the things there too...
Well, that settles it. God willing, I'll be living in a house with 12V electricity within a couple of years. And I should turn off my wifi, it is only for my phone, and I don't really use my phone. I should put it at a distance from where I spend my time when it's not in use also.
Big thanks for informing me :)
