Former exploratory investigations of sleep alterations due to global system for mobile communications (GSM) signals have shown a hypnotic and REM-suppressive effect under field exposure. This effect was observed in a first study using a power flux density of 0.5 W/m(2), and the same trend occurred in a second study with a power flux density of 0.2 W/m(2). For the present study, we applied a submaximal power flux density of 50 W/m(2). To investigate putative effects of radio frequency electromagnetic fields (EMFs) of cellular GSM phones on human sleep EEG pattern, all-night polysomnographies of 20 healthy male subjects both with and without exposure to a circularly polarized EMF (900 MHz, pulsed with a frequency of 217 Hz, pulse duration 577 microseconds) were recorded. The results showed no significant effect of the field application either on conventional sleep parameters or on sleep EEG power spectra.
先前对全球移动通信系统（GSM）信号导致睡眠改变的探索性研究表明，在实地暴露条件下，GSM信号具有催眠和抑制快速眼动睡眠的作用。在第一项研究中，当功率通量密度为0.5W/m²时观察到了这种效应，而在第二项功率通量密度为0.2W/m²的研究中也出现了相同的趋势。在本研究中，我们应用了50W/m²的次最大功率通量密度。为了研究蜂窝式GSM手机的射频电磁场（EMF）对人类睡眠脑电图模式的假定影响，我们记录了20名健康男性受试者在暴露于圆极化EMF（900MHz，频率为217Hz脉冲，脉冲持续时间577微秒）和未暴露于该EMF两种情况下的整夜多导睡眠图。结果表明，施加该电磁场对传统睡眠参数或睡眠脑电图功率谱均无显著影响。
