我们调查了看喜剧和悲剧视频引起的笑和哭对情绪和自主神经功能的影响。10名健康的女性受试者自愿参加了这项实验。在观看喜剧或悲剧视频之前、之后和期间记录胸电和呼吸曲线。我们还要求他们填写情绪状态简档(POMS)，以评估他们在观看视频时的情绪状态。心率变异性(HRV)频谱分析评价自主神经功能。所有受试者在观看喜剧和悲剧视频时都或多或少地笑了或哭了。观看喜剧视频后，POMS的愤怒-敌意得分显著下降，活力得分显著上升，而抑郁-抑郁得分在观看悲剧视频后显著上升。虽然这两种成分都有增加心率变异性中低频成分与高频成分之比的趋势，但反应的时间进程不同。反映心脏交感迷走神经平衡的低频/高频比值在开始观看喜剧视频后立即升高，在停止观看后立即恢复到基础水平，而在观看悲剧视频时，低频/高频比值逐渐增加，幅度较小。相反，反映心脏副交感神经活动的高频成分在观看两个视频时逐渐减少，但在观看悲剧视频后并未恢复到基础水平。这些结果表明，笑对自主神经系统有强烈但短暂的影响，而哭泣或感到悲伤对其有中等但持续的影响。
We investigated the effects of laughing and weeping induced by watching comedy and tragedy videos on mood and autonomic nervous function. Ten healthy female subjects volunteered for the experiment. Chest electrocardiogram and respiration curve were recorded before, after, and during watching a comedy or a tragedy video. We also asked them to fill out profiles of mood states (POMS) to evaluate their mood states while watching videos. Autonomic nervous function was estimated by spectral analysis of heart rate variability (HRV). All subjects more or less laughed and wept while watching comedy and tragedy videos, respectively. Anger-hostility score of the POMS decreased and vigor score increased significantly after watching comedy videos, while depression-dejection score increased significantly after watching tragedy ones. Although both contents tended to increase a low to high frequency component ratio (LF/HF ratio) of HRV, the time course of responses was different. The LF/HF ratio which reflects cardiac sympathovagal balance increased immediately after they started watching comedy videos, and returned to the basal level right after they stopped watching, whereas the LF/HF ratio increased gradually to a lesser extent while watching tragedy videos. In contrast, the high-frequency component which reflects cardiac parasympathetic nerve activity gradually decreased while watching both videos but did not return to the basal level after watching tragedy ones. These results suggest that laughing has strong but transient effects on the autonomic nervous system, while weeping or feeling sad has moderate but sustained effects on it.
