As societies industrialize and the technological revolution continues, the number and diversity of electromagnetic field source has been an unprecedented increase . These radiation sources including computers, mobile phones and their base stations video display units. While these devices have made our life richer , safer and more convenient , but they have been accompanied to their EMF emissions possible health risk concerns.

Many individuals have reported a period of time associated with EMF exposure they consider a variety of health problems. While some individuals report mild symptoms and react by avoiding the fields as much as possible , but others are so severely affected that they cease work and change their entire lifestyle . This reputed sensitivity to EMF generally termed "electromagnetic hypersensitivity ."

This fact sheet describes what is known about the condition and to provide information to help people with such symptoms . The information provided on a WHO Workshop on Electrical Hypersensitivity ( 2004 in Prague, Czech Republic ) , electromagnetic fields and non-specific health symptoms International Conference (COST244bis, 1998 ), the European Commission report (Bergqvist and Vogel, 1997 year) and recent reviews of the literature .

EHS is characterized by a variety of non-specific symptoms, can be attributed to exposure to EMF personal suffering. These common symptoms include dermatological symptoms (redness, tingling and burning sensations) as well as neurasthenic and vegetative symptoms (fatigue, tiredness, concentration difficulties, dizziness, nausea, heart palpitation, and digestive disturbances). Of symptoms is not part of any recognized syndrome.

EHS resembles multiple chemical allergies, and low-level environmental exposures to chemicals related to another disorder. Electromagnetic Hypersensitivity and multiple chemical allergies are characterized by a range of non-specific symptoms that lack apparent toxicological or physiological basis or independent verification. Sensitivity to environmental factors for the more common name for the IEI, which originated from WHO's International Programme on Chemical Safety held in Berlin in 1996, a workshop. IEI is a descriptor word, without any chemical etiology, immunological sensitivity or EMF susceptibility. IEI incorporates a number of diseases, they have an adverse impact on people's medicine can not explain the similar non-specific symptoms. However, given that the term EHS is in common usage will continue to use the term here.

For the general population, the prevalence of EHS There is a very wide range of estimates. An occupational medical centers estimated the prevalence of EHS to 30 people per million population. However, a self-help groups yielded much higher estimates. EHS is about 10% of reported cases were considered severe.

The prevalence of EHS and in the reported symptoms, there are considerable regional differences. In Sweden, Germany and Denmark reported incidence of hypersensitivity to electromagnetic radiation than the United Kingdom, Austria, and France. VDU-related symptoms in the Scandinavian countries is relatively common, and they are more common than elsewhere in Europe with skin disorders. EHS individuals with reported symptoms similar to the general population is common.

A number of studies have been carried out, where EHS individuals were exposed to them will be attributed to the cause of their symptoms to EMF similar. Aimed at controlling the symptoms induced under laboratory conditions.

Most studies indicate that EHS individuals than non-EHS individuals detect EMF exposure any more accurately. Well controlled and conducted double-blind studies have shown that symptoms associated with EMF exposure.

It was said that some EHS
