It's not a new phenomenon. People have been discovering that they are elecromagnetically sensitive more and more. It's becoming a well-known phenomenon.
Everyone is effected by electromagnetic radiation, but most people will be able to overcome this stress. However, a sizable minority, say like 40% of the population, will exibit harmful health effects.
Try this experiment: Turn off all wifi, radiation emitting devices at night (cell phone, laptops, tablets, TVs, routers etc), in your house and cut all of the electricity to your bedroom at the breakers for a night or two. See if you don't sleep harder than you ever have in your entire life. If the answer is yes, you may be one of the "sizable minority" of us who could be EMF sensitive.
If you realize that you are, you might want to investigate whether or not you have a smart meter anywhere near your domicile and do something about it if you can.
