Dr. Erica Mallery-Blythe’s PDF on EHS.

Those with Electromagnetic Hypersensitivity (EHS) are another vulnerable group, and some children also have EHS making them additionally at risk. EHS is a multisystemic physical condition hallmarked by classical symptom constellations (such as headaches, insomnia, mood disturbance, palpitations etc), in response to anthropogenic (man made), electromagnetic fields of various types.

The condition has been documented in various forms since the birth of the use of electromagnetic fields by man, back in the early 1900s. Increased exposures associated with rapidly evolving emitting technologies, are leading to an ever-growing number of complaints from those who have identified electromagnetic fields as the source of their problems and also increases in reports of the cardinal symptoms in the general population, who may not realise that EMR may be the cause of their complaints.

Thank you to Santini et al 2003


Triggers for the symptoms can be any EMF exposure, but classically it is a reaction to the pulse modulated fields associated with mobile telephony and Wi-fi. Some individuals will also suffer symptoms from the lower household electrical (ELF) fields.

EHS can progress quickly in some individuals, rendering them incapacitated by their severe symptoms and unable to tolerate even minute exposures to certain frequencies. Unfortunately as very few doctors have been educated regarding the condition and internet sources are often factually inaccurate or subject to bias, it can be very difficult for individuals to receive appropriate support to improve their health. The mainstay of management is to avoid the EMR triggers, but this can prove extremely difficult given the ubiquitous nature of Wi-fi and mobile phone radiation now pervasive in society. As well as creating a general public health decline, this is also raising serious human rights concerns, and unsurprisingly, the condition appears to be rising in response to increased exposures. For more detail regarding Electromagnetic Hypersensitivity, please see the EHS section under the ‘resources’ tab above.
