Aim of study (acc. to author)

The article gives an extended overview over the situation of the electromagnetic hypersensitivity issue in relation to electromagnetic field research in the international scientific community.

Background/further details

The first part of the article deals with the biophysical fundamental knowledge of interactions between electromagnetic fields and biological systems including threshold values. Then hypothetical mechanisms of action of electromagnetic fields are demonstrated, with a special focus on the melatonin hypothesis. Additionally, in the context of biomedical research into disorders of well-being an analysis of written and telephone questions about the electromagnetic field issue which are sent to the centre of electropahtology was conducted (Witten/Herdecke, Germany). Results of an experimental approach are presented (20 women and 9 men participated).
