|Tim Hallam, 36, sleeps in a custom-made silver-coated|
sleeping bag that helps block out electromagnetic fields.
Is modern life making us ill? Yes, say those who suffer from electrosensitivity. Are they cranks, or should we all be throwing away our mobile phones?
Tim Hallam is just tall enough to seem gangly. His height makes the bedroom feel even smaller than it is. Muddy sunlight filters through the grey gauze hung over his window. His narrow bed appears to be covered with a glistening silver mosquito net. The door and the ceiling are lined with tinfoil. Tim tells me there is also a layer of foil beneath the wallpaper and under the wood-effect flooring. He says, "The room is completely insulated; the edges are sealed with aluminium tape and connected with conducting tape so I could ground the whole room. It's a Faraday cage, effectively. Grounding helps with the low frequencies radiation, apparently. The high frequencies just bounce off the outside."
