Cardiac vagal control (CVC) has been linked to both physical and mental health. One critical aspect of health, that has not received much attention, is sleep. We hypothesized that adults with higher CVC--operationalized by high-frequency heart rate variability (HF-HRV)--will exhibit better sleep quality assessed both subjectively (i.e., with Pittsburgh Sleep Quality Index) and objectively (i.e., with polysomnography). HF-HRV was measured in 29 healthy young women during an extended neutral film clip. Participants then underwent full polysomnography to obtain objective measures of sleep quality and HF-HRV during a night of sleep. As expected, higher resting HF-HRV was associated with higher subjective and objective sleep quality (i.e., shorter sleep latency and fewer arousals). HF-HRV during sleep (overall or separated by sleep phases) showed less consistent relationships with sleep quality. These findings indicate that high waking CVC may be a key predictor of healthy sleep.
心脏迷走神经控制（CVC）与身心健康都有关联。睡眠作为健康的一个关键方面，却未得到太多关注。我们假设，通过高频心率变异性（HF-HRV）来衡量的CVC较高的成年人，在主观（即使用匹兹堡睡眠质量指数）和客观（即使用多导睡眠图）评估中都将表现出更好的睡眠质量。在观看一段较长的中性电影片段期间，对29名健康年轻女性的HF-HRV进行了测量。参与者随后接受了全夜多导睡眠图检查，以获取睡眠质量和睡眠期间HF-HRV的客观测量值。正如预期的那样，较高的静息HF-HRV与较高的主观和客观睡眠质量相关（即较短的睡眠潜伏期和较少的觉醒次数）。睡眠期间的HF-HRV（总体或按睡眠阶段分开）与睡眠质量的关系不太一致。这些发现表明，较高的清醒时CVC可能是健康睡眠的关键预测指标。
