Aim: In recent years in Japan, forest therapies have been implemented in various places. While the effects of such therapies have been reported in previous research papers, those of artificial gardens have not been clarified. At the 2018 Yamaguchi Yume Flower Expo, the Yamaguchi University Faculty of Medicine had the opportunity to provide a "Well-being Garden" in collaboration with the Japan Landscape Contractors Association Yamaguchi Prefecture Branch. We examined the physical and mental responses of older people who strolled in the Well-being Garden.
Methods: Participants were 158 people ≥ 65 years old. Pre-and post-stroll interviews were conducted, and the heart rate, blood pressure, and autonomic nervous activities were measured.
Results: After strolling in the garden, the heart rate significantly decreased from 76.1±12.9 to 73.9±11.8/min (p<0.01), and both the systolic and diastolic blood pressure significantly decreased from 142.5±24.4 to 139.4±24.1 mmHg and from 83.7±12.0 to 81.5±11.9 mmHg, respectively (p<0.01). The ralue of low frequency/high frequency (LF/HF) after strolling in the garden came closer to the standard one than before, both in the participants with much tension and with less tension. In the post-stroll interview, 74 reported feeling very good, and 84 felt good.
Conclusions: These results suggested that strolling in the Well-being Garden positively influenced the physical and mental condition of the participants.
