Sensitivity to the environment is one of the pleasures of life. Unfortunately, for certain individuals this gets out of control. They become hypersensitive to something around them: pollens, moulds, man-made chemicals or to certain foods or drinks. If this is allowed to develop, sensitivity to the electrical environment may also appear as a part of the overall package of sensitivities. The same symptoms will then appear when the individual is in proximity to computers, televisions, telephones, supermarket check-outs, fluorescent lighting and even weather fronts and sunlight. The author has been involved in the diagnosis and treatment of electromagnetic sensitivities with complementary therapy since 1982, and considers here the nursing problems these patients present.
