Summary

The research involved 27 older adults who participated in four types of horticultural activities—Grass Doll (sowing seeds), Kokedama (plant wrapping), Rocky Leaf Prints (artistic creation), and Herb Tasting and Smelling (sensory engagement). Results showed that all activities reduced pulse rate and salivary amylase activity (SAA), indicators of stress, but the Rocky Leaf Prints and Herb Tasting activities had the strongest effects on relaxation and mood enhancement. Heart rate variability (HRV) analysis also confirmed that these activities lowered stress responses and promoted emotional well-being.

Psychologically, participants reported less tension, fatigue, and confusion after engaging in these horticultural tasks. Artistic and sensory-based activities had the most immediate effects, while cultivation-based tasks (such as sowing seeds) may require longer-term engagement to show benefits. The study highlights that horticultural activities can be tailored to maximize their physical and psychological benefits for older adults, particularly in community and elder care settings
