Electromagnetic Fields
The effects of Electromagnetic Fields (EMF) on the human body have not been extensively studied, and any research that has been done has not been widely publicized. This is probably due to the fact that electronic gadgets are extremely useful, everybody has them, and people in general are afraid to look too closely for fear of what they might find.
For example, take the fascination and hype about 5G networks. This is a very promising technology (both in usefulness and profitability) that has had almost zero investigation into what possible effects (if any) having high-energy wavelengths in close proximity to the population one might expect.
In these pages, I will attempt to list serious investigations as I encounter them.
