Electricity allergy

The Globe and Mail reports on electrosensitivity, basically an allergy to electricity that some people claim causes pain, headaches, lousy sleep, depression, rashes, and fatigue. Whether electrosensitivity exists or not is a topic of debate, but it's very real to those who say they're suffering from it. From the article:

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...

The change in power quality means more variable electromagnetic fields, and possibly more biologically active ones, are associated with electricity than there used to be. This is a possible explanation for the rise in electrosensitivity complaints in the view of Denis Henshaw, a professor at the University of Bristol in Britain, who is an international authority on the health effects of power transmission lines.

He says that if electricity were flowing in a constant way, most people's bodies would likely adapt, but with all the interference from modern devices, the resulting fields are too variable for people to get used to. "We just don't get to adapt to these because they don't have any special pattern to them," he said. "There is no proof of this, it's just an opinion."
