Abstract

In the present study we investigated the influence of pulsed high-frequency electromagnetic fields of digital mobile radio telephones on sleep in healthy humans. Besides a hypnotic effect with shortening of sleep onset latency, a REM suppressive effect with reduction of duration and percentage of REM sleep was found. Moreover, spectral analysis revealed qualitative alterations of the EEG signal during REM sleep with an increased spectral power density. Knowing the relevance of REM sleep for adequate information processing in the brain, especially concerning mnestic functions and learning processes, the results emphasize the necessity to carry out further investigations on the interaction of this type of electromagnetic fields and the human organism.

Main findings

Pulsed high-frequency electromagnetic fields from digital mobile radio telephones were associated with shortened sleep onset latency and reduced REM sleep duration and percentage. EEG spectral analysis during REM sleep showed increased spectral power density, described as qualitative alterations of the EEG signal.
