To investigate the effects of pulsed high-frequency electromagnetic fields emitted by digital cellular phones on sleep in healthy humans.
|ばく露時間||continuous for 8 h|
|Pulse width||580 µs|
|Repetition frequency||217 Hz|
|Distance between exposed object and exposure source||40 cm|
|ばく露装置の詳細||A cellular phone was installed at the top of the bed at a distance of 40 cm from the vertex of the subject.|
|Additional information||The subjects were exposed in one night and sham-exposed in another night (randomised, single-blind).|
Besides a hypnotic effect with shortening of sleep onset latency, a REM sleep suppressive effect with reduction of duration and percentage of REM sleep was found under radiation. Spectral analysis revealed an increased spectral power density of the EEG signal during REM sleep (especially in the alpha band).
