In order to investigate the effects of on-call duty on sleep and wakefulness, five male ships' engineers were studied using electroencephalogram (EEG) and electrocardiogram (ECG) recordings and subjective ratings. Sleep during on-call nights (two alarms) was shortened and contained less slow wave sleep (SWS) and rapid eye movement (REM) sleep, lower spectral power density, and a higher heart rate. Many of the effects were observable before any alarms had occurred. Rated sleep quality was lower, and sleepiness was higher during the subsequent day. It was suggested that the effects were due to apprehension/uneasiness induced by the prospect of being awakened by an alarm.
为了研究待命值班对睡眠与清醒状态的影响，对五名男性船舶工程师进行了研究，采用脑电图（EEG）和心电图（ECG）记录以及主观评分。待命值班当晚（两次警报）的睡眠时间缩短，慢波睡眠（SWS）和快速眼动（REM）睡眠减少，频谱功率密度降低，心率加快。许多影响在任何警报发出之前就已显现。随后一天的睡眠质量评分较低，困倦程度较高。研究表明，这些影响是由被警报唤醒的可能性所引发的忧虑/不安所致。
