Abstract
The temporal organization of the sleep of night workers was compared to that of day workers. The seven night workers had all worked the night shift for at least 1 month, and most had worked many months on a night shift. These subjects tended to return at least partially to night time sleep on their days off from work. A control group of nine day workers/night sleepers was used for comparison purposes. There were 89 day sleep sessions and 81 night sleep sessions for analysis in terms of the period and amplitude of the intra sleep rapid eye movement (REM)/non rapid eye movement (NREM) ultradian sleep cycle. Electroencephalogram and eye movements during sleep were recorded by standard techniques. Significant differences in terms of the period and amplitude of the intra sleep REM/NREM ultradian sleep cycle were not detected between the two groups. The temporal organization within individual day sleep sessions was not disrupted enough to discriminate them from night sleep. However, the day sleepers did have considerably more atypical sleep sessions when there were only two REM periods of awakenings of over 10 minutes duration. The authors conclude that circadian modulation of ultradian oscillations during sleep are impaired in night workers.
