It looks like there is a rise world wide of people who suffer from, what is being called "Electromagnetic Sensitivity". The symptoms are headache, fatigue and problems sleeping. While both the industry and doctors are still unable to say for certain that this condition exists they do have this to say.
"Power quality is a well-known problem in the utility business, caused by the proliferation of computers, lighting dimmer switches, energy efficient bulbs, and other modern electronic gadgets. These new devices cause a more complicated use pattern for electricity than old-fashioned items such as incandescent bulbs, producing negative feedback involving high-frequency peaks, harmonics and other noise on electric wiring."
However one industry leader has this to say about the phenomenon, which generally is fixed by installing $1000 USD to install filtering.
"The utility industry's Mr. Sahl is skeptical about efforts to improve power quality, which generally cost about $1,000 to handle one home, and calls them a "waste of money."
He agrees that the action may make some people feel better, but only because they're affected by the power of suggestion and not by the power of electricity. "I hate to be blunt about it, but there is this well-established effect in science and we've studied it over and over and it's called the placebo effect."
Personally I don't think that people can be this sensitive to EM radiation. Maybe sharks and other highly sensitive animals, but I'm not sure. Bunk or fact?
