The purpose of this study is to explore physiological and psychological changes immediately after a short-term visit to urban parks in an uncontrolled condition. Sixty park visitors completed a short questionnaire evaluating their subjective well-being (SWB) and donated a saliva sample immediately before and after their park visit. In addition, participants wore a pedometer to track their physical activity level during the park visit. Results indicated the levels of all biomarkers (cortisol, dehydroepiandrosterone [DHEA], and cortisol/DHEA ratio) decreased while SWB scores increased after the park visit. The duration of park visit was identified as a key variable significantly associated with cortisol reduction, and changes in SWB scores after the park visit were significantly associated with changes in cortisol level. A park visit duration of 21.8 min has the predictive ability to discriminate park visitors who exhibit reductions in cortisol levels after the park visit from those who do not.
本研究的目的是在非受控条件下，探究短期参观城市公园后立即出现的生理和心理变化。60名公园游客完成了一份简短问卷，评估他们的主观幸福感（SWB），并在参观公园前后立即捐献了唾液样本。此外，参与者佩戴了计步器，以追踪他们在公园参观期间的身体活动水平。结果表明，参观公园后，所有生物标志物（皮质醇、脱氢表雄酮[DHEA]和皮质醇/DHEA比值）水平均下降，而SWB得分增加。公园参观时长被确定为与皮质醇降低显著相关的关键变量，参观公园后SWB得分的变化与皮质醇水平的变化显著相关。21.8分钟的公园参观时长具有预测能力，能够区分参观公园后皮质醇水平降低的游客和未降低的游客。
