A woman we shall call Sarah first came to see me as a patient with something of an unusual complaint. Several years earlier she started developing an array of unusual symptoms: amongst other things, her heart rate had increased to around 120 beats per minute, her body temperature had increased, she began to lose weight and her hair started flattening out. What was curious was the fact that she could pinpoint the day when her symptoms began to appear and this led her to explore what could have changed around that time. It led her to discover that this was the day that the store underneath her apartment had installed a Wifi network. Her sensitivities to these manmade electromagnetic frequencies (EMF) although not ‘typical’, are certainly not unique either. In my own practice, I have come across a number of people with similar complaints and there are entire communities in remote parts of the country established as EMF free zones for just such people.
