I am subscribed to a great channel on YT- the host is a health writer and researcher, a true renegade in the field.
I have come to really value and trust his opinions and advice over the last year.
His most recent video is about compact fluorescent light bulbs and the problems they can pose to our health- namely the high level of electromacgnetic frequencies that they emit, which apparently can damage our reproductive health. (Yeah, like we need more of THAT in this day and age!)
Also, obviously having many sources of electromagnetics (computers, light bulbs, tv, etc) creates a compounding effect too. He talks about an alternative to CFL's also.
