Sleep quality in subjects living in the vicinity of mobile phone basestations - pilot study


Indications exist that the sleep parameters, the brain waves (EEG) and the processing of intellectual information are influenced by exposures to mobile phone fields, i.e. at field intensities below accepted limit values. Whether this also applies to the weak fields emitted from base stations has not been studied yet. Epidemiological studies of the influence of high frequency electromagnetic fields on the quality of sleep and well-being have shown contradictory results. The main focus of this project is to study diverse sleep parameters in population groups living near mobile telecommunication base stations (500 m). The quality of sleep at home will be studied using two methods, survey and registration of physiological parameters (sleep EEG). This will be done in a double-blind study in cross-over design. The evaluation of subjective and objective data should provide information about the influence of high frequency electromagnetic fields on the quality of sleep. The possible influence of psychological components will be taken into account and evaluated. Results of a feasibility study are available. The objective is to examine the influence of high frequency electromagnetic fields of mobile telecommunication base stations on residents' quality of sleep in a double-blind study.
