There are people who attribute such symptoms to exposure to low-intensity electromagnetic fields. This was termed electromagnetic hypersensitivity. In October 2004, the World Health Organisation held a conference in Prague on this topic. The conclusion was that there is no scientific basis for attributing these symptoms to low-intensity electromagnetic waves and that electromagnetic hypersensitivity is not a medical diagnosis. There are many other factors which influence the organism and can cause the same effects. In December 2005, the World Health Organisation published Report 294 – Electromagnetic Hypersensitivity (www.who.int/mediacentre/factsheets/fs296/en/index.html), which reiterates the conclusions of the conference and presents the results of laboratory studies which establish the fact that these individuals cannot detect the presence of an electromagnetic field more easily than regular people.
