Forest therapy involves visiting forests or conducting forest-based treatment activities to improve one's health. Studies have investigated the health benefits of forests, but consensus has not been reached. This study comprised a systematic review and meta-analysis to determine how forest therapy affects the physiological and psychological health of adults. The Cumulative Index to Nursing and Allied Health Literature, Embase, and Medline databases were searched on 31 August 2021. Systematic review and meta-analysis, risk evaluation, GRADE evaluation, and advertisement effect evaluation were performed for each article. The effect size was calculated by dividing blood pressure as a physiological indicator and depression as a psychological indicator. Of the 16,980 retrieved studies, 17 were selected based on the inclusion criteria. Of these, eight studies were included in the meta-analysis. The effect size of forest therapy on improving systolic and diastolic blood pressure was not significant; however, it significantly reduced depression. While the results have limited generalizability due to the inclusion of few studies, the effects of forest therapy on reducing depression have been confirmed. Since the application of forest therapy was heterogeneous in these studies, a moderator effect analysis or subgroup analysis in meta-analysis should be performed in the future.
森林疗法是指通过参观森林或进行基于森林的治疗活动来改善人们的健康。目前已有研究调查了森林对健康的益处，但尚未达成共识。本研究采用系统评价和荟萃分析，以确定森林疗法对成年人的生理和心理健康有何影响。于 2021 年 8 月 31 日检索了 Cumulative Index to Nursing and Allied Health Literature、Embase 和 Medline 数据库。对每篇文章进行了系统评价和荟萃分析、风险评估、GRADE 评估和广告效果评估。生理指标为血压，心理指标为抑郁，用血压除以抑郁来计算效应量。在检索到的 16980 篇研究中，根据纳入标准选择了 17 篇。其中，有 8 项研究纳入荟萃分析。森林疗法对改善收缩压和舒张压的效果不显著，但可显著降低抑郁程度。由于纳入的研究较少，结果的普遍性有限，但已证实森林疗法可降低抑郁程度。由于这些研究中森林疗法的应用存在异质性，未来的荟萃分析应进行调节效应分析或亚组分析。
