Like increasing numbers of people, Mary believes she suffers from electromagnetic hypersensitivity intolerance syndrome (EHS) – in other words, she thinks the electronic devices most of us rely on in our everyday lives are making her ill.
These range from mobile phones to television screens and even light bulbs. The waves are a form of non-ionising radiation, designed to be too low in frequency to affect people.
However, EHS sufferers believe this low-level radiation is capable of causing harm, and report symptoms ranging from headaches, lethargy and nausea to breathing difficulties and even paralysis. They also fear the radiation may cause cancer, autoimmune diseases and neurological disorders in the long-term.
‘Before I developed EHS in 2012, I wouldn’t have believed the condition existed,’ says Mary. ‘The idea of becoming ill because of the technology I’d used for years without previously having any problems is surreal.
