Sarah, 51, is one of a growing band of people who claim to be experiencing extreme - and incapacitating - sensitivity to electrical appliances, as well as to certain frequencies of electromagnetic waves. [...] This may sound bizarre, but there is no doubt that Sarah's symptoms are real. To date, they include hair loss, sickness, high blood-pressure, digestive and memory problems, severe headaches and dizziness. They strike with such ferocity that, since diagnosing herself as "electrically sensitive" in May 2005, she has been marooned at home. [...] And she can venture into built-up areas only if she is swathed in a net-and-hat ensemble made from a special "shielding fabric" that makes her look like a bee-keeper. [...] Convinced that she had almost certainly found the cause of her illness, she ordered, from the internet, some special rolls of foil wallpaper and a fabric called Swiss bobbinet - a netting made from polyester filaments dipped in silver. [...] Both promised to "shield" her from any emissions from phone masts or wireless broadband systems. [...] Using an "electrosmog detector" - the name given to a device that can apparently register levels of electromagnetic activity - she checked her bedroom. "And there was radiation streaming in through the one wall that I thought I hadn't needed to protect. We have some new neighbours, and I think they must have installed wireless broadband." To ensure a good night's sleep, Sarah now takes the precaution of swathing herself in her special silver netting. |
