Summary
The research involved 30 allotment gardeners who completed a stress-inducing Stroop task before being randomly assigned to 30 minutes of gardening or indoor reading. Salivary cortisol levels and mood assessments were taken at multiple points. Results showed that both activities reduced stress, but gardening led to a significantly greater decrease in cortisol and a full restoration of positive mood, while mood deteriorated in the reading group.
These findings provide strong experimental evidence that gardening promotes physiological and emotional recovery from stress. The study supports gardening as a therapeutic activity, reinforcing its role in mental health interventions and stress management programs​
