A Pilot Study: Horticulture-related Activities Significantly Reduce Stress Levels and Salivary Cortisol Concentration of Maladjusted Elementary School Children
Summary
This study investigated whether horticulture-related activities (HRAs) could reduce stress in maladjusted elementary school children. Twenty children were divided into two groups: one group participated in floral arranging, planting, and flower pressing activities, while the other group engaged in their favorite indoor activities. Over nine weeks, the experimental group completed the HRAs, and their stress levels were measured using a stress scale and by analyzing their saliva for cortisol, a stress hormone.
The study found that the children participating in the HRAs experienced a decrease in stress related to interpersonal relationships, school life, personal problems, and home life. In particular, stress related to school life was significantly reduced. The analysis of saliva samples showed that floral arranging, planting, and flower pressing activities reduced cortisol levels by at least 37% compared to levels before the activities. The researchers concluded that HRAs can effectively reduce stress levels in maladjusted elementary school children.
