Middle age, female sex and poor perceived health was found to be associated with electomagnetic hypersensitivity (EHS). Of a group of self-reporting EHS sufferers (n=91), more than half had EMF-related symptoms more often than once a week, and the mean number of years experiencing EHS was 10.5. More than half of the EHS group reported that their symptoms started after a high-dose or long-term EMF exposure, that they actively tried to avoid EMF sources and that they mostly could affect the EMF environment. A minority had sought medical attention, been diagnosed by a physician or received treatment. Exhaustion syndrome, anxiety disorder, back/joint/muscle disorder, depression, functional somatic syndrome and migraine were found to be comorbid with EHS.
