Existing research on the effects of nature exposure on the mental health of adults indicates that spending time in nature reduces depressive symptoms and stress, increases quality of life and mood and improves mental health. This meta-analysis aimed to answer the question: what are the effects of nature exposure on the social, mental and physical health of adults with symptoms of mental illness? The meta-analysis included all studies relevant to the study research questions which collected quantitative data on nature exposure using validated instruments for at least two time points on each participant and which were published between 1990 and 2020. Regarding the impact of nature exposure on adults with symptoms of mental illness, analyses showed significant, moderate effect sizes for all studies and smaller, but significant, effect sizes for studies with control groups Analyses also yielded critical information regarding the effect size of the type of nature dosage, nature setting, nature-based activity, key mental health outcomes and other factors. These findings from the present study results have important implications regarding the potential benefits of nature exposure for adults and its role in healthcare.
现有研究表明，接触自然对成年人的心理健康有积极影响，能减轻抑郁症状和压力，提高生活质量和情绪，改善心理健康。本荟萃分析旨在回答以下问题：接触自然对有心理健康问题症状的成年人的社会、心理和身体健康有什么影响？荟萃分析纳入了所有与研究问题相关的研究，这些研究使用经过验证的工具收集了参与者在至少两个时间点的自然暴露数据，并在 1990 年至 2020 年期间发表。关于接触自然对有心理健康问题症状的成年人的影响，分析显示所有研究的效应量均有显著的中等效应，而有对照组的研究的效应量较小，但仍具有显著意义。分析还提供了有关自然剂量类型、自然环境、基于自然的活动、主要心理健康结果和其他因素的效应量的关键信息。本研究结果的这些发现对于接触自然对成年人的潜在益处及其在医疗保健中的作用具有重要意义。
