目的积极影响（PA）与更好的健康有关。然而，这种联系背后的生物学途径还没有得到很好的理解。PA的不同方面（如低激活与高激活）和状态和特质PA可能有不同的生理效应。（即状态）和聚合（即，性状样）PA至心脏迷走神经张力（心率变异性; HRV）在日常生活中（N= 122，连续记录3天）。结果聚集激活PA与较高的动态HRV相关，而瞬时PA激活时伴有较低的HRV。此外，瞬时失活的PA伴随着较高的HRV，但聚集失活的PA不伴随。调查结果是独立的负面影响和其他各种人口和行为confounds.ConclusionsTogether的研究结果表明，PA的健康相关的影响更复杂的图片。虽然PA的状态相关波动似乎对心脏产生激活和失活作用，但激活的PA在聚合水平上似乎抑制心脏唤醒，从而表明对健康有益。（PsycInfo数据库记录（c）2020阿帕，保留所有权利）
ObjectivePositive affect (PA) has been related to better health. However, the biological pathways underlying this link are not well understood. Different facets of PA (eg, low activated vs. high activated) and both state and trait PA might have different effects on physiology.MethodThis study aimed to relate low-and high-activated facets of momentary assessed (ie, state) and aggregated (ie, trait-like) PA to cardiac vagal tone (heart rate variability; HRV) in everyday life (N= 122, with 3 successive recording days).ResultsAggregated activated PA was associated with higher ambulatory HRV, whereas activated momentary PA was accompanied by lower HRV. Moreover, momentary deactivated PA was accompanied by higher HRV, but aggregated deactivated PA was not. Findings were independent of negative affect and various other demographic and behavioral confounds.ConclusionsTogether the findings suggest a more complex picture of the health-related effects of PA. Whereas state-related fluctuations in PA seem to exert both activating and deactivating effects on the heart, activated PA on an aggregated level seems to dampen cardiac arousal, thus suggesting beneficial effects for health.(PsycInfo Database Record (c) 2020 APA, all rights reserved)
