Summary

The effectiveness of horticultural therapy (HT) in reducing stress is analyzed in this systematic review. 31 studies were examined focusing on both psychological and physiological indicators of stress. Results showed that HT significantly improved psychological indicators of stress compared to control groups, but had insignificant effects on physiological indicators. Subgroup analysis revealed that the stress-reducing effects of HT were related to the population characteristics and were most effective in indoor and virtual settings, with a total duration of 100–500 minutes showing better results. The authors proposed a theoretical framework based on “Participants-Settings-Interventions” to guide future HT activities for stress reduction.
