夜班有负面的认知结果，白天小睡可能会减弱。神经内脏整合模型表明，静息迷走神经介导的心率变异性（vmHRV）与认知功能有关。本研究旨在探讨实习生倒班后小睡不同时间后静息时的vmHRV与认知功能的关系。共105名实习生被随机分配到三组（非午睡组，n = 35;午睡15分钟组，n = 35;午睡45分钟组，n = 35）中的一组，在12：00，15：00和18：00进行认知测试和静息vmHRV。评估信息处理（数字符号替代测试; DSST），运动速度（手指敲击测试; FTT），反应选择（选择反应时间; CRT）和注意转移（转移注意力测试; SAT）。在基线和各组的每个认知任务期间评估静息vmHRV。与非午睡对照组相比，15分钟和45分钟午睡改善了15：00时的所有结果指标（包括主观嗜睡和认知表现），18：00时仍有一些益处。小睡15分钟对午睡后15：00的FTT产生的益处显著大于小睡45分钟。静息vmHRV与DSST和SAT成绩显著相关。此外，FTT表现是不同午睡时间DSST表现的唯一重要预测因素。我们的研究结果表明白天小睡（特别是15分钟的小睡）和改善认知控制之间的联系，与实习生轮班工作后的自主活动有关。这些结果表明，清醒时的自主活动起着至关重要的作用，DSST和SAT性能，并促进了不同的午睡时间后的信息处理的神经认知机制的差异的理解。
Night shifts have adverse cognitive outcomes that might be attenuated by daytime napping. The neurovisceral integration model suggests that resting vagally mediated heart rate variability (vmHRV) is linked with cognitive function. This study investigated the relationship between resting vmHRV and cognitive function after different nap durations in interns after shift work. A total of 105 interns were randomly allocated to one of three groups (non-nap, n = 35; 15-min nap, n = 35; 45-min nap, n = 35) to perform cognitive tests and resting vmHRV at 12:00, 15:00 and 18:00. Information processing (digit symbol substitution test; DSST), motor speed (finger tapping test; FTT), response selection (choice reaction time; CRT), and attention shifts (shifting attention test; SAT) were assessed. Resting vmHRV was assessed at baseline and during each cognitive task across groups. Compared with the non-nap control, the 15-min and 45-min naps improved all outcome measures (including subjective sleepiness and cognitive performance) at 15:00, with some benefits maintained at 18:00. The 15-min nap produced significantly greater benefits on the FTT at 15:00 after napping than did the 45-min nap. Resting vmHRV was significantly correlated with DSST and SAT performance. In addition, FTT performance was the only significant predictor of DSST performance across different nap durations. Our results demonstrate links between daytime napping (in particular, a 15-min nap) and improved cognitive control in relation to autonomic activity after shift work in interns. These results indicated that autonomic activity when awake plays a crucial role in DSST and SAT performance and facilitated the understanding of differences in neurocognitive mechanisms underlying information processing after different nap durations.
