摘要: Abstract In order to study the effects of short daytime sleep on sleepiness, 6 healthy male subjects were exposed 3 experimental conditions — long night (23.00–07.00 h), (03.00–07.00 h) and day (07.00–11.00 h). Sleepiness was measured in 2 h intervals by EEG-based multiple latency test (MSLT) self-ratings. The results showed a pronounced circadian rhythmicity with peak length (lowest sleepiness) evening (19.00–23.00 minimum (highest early morning (05.00 Around 15.00 secondary (temporary) found for all conditions. shortened began have sleepiness (shorter latencies) afternoon, around 19.00 h. This effect had character delay normal rise (alertness). similar effects. MSLT covaried moderately rectal temperature rated (negatively). It concluded that loss influences combined sleepiness.
