Research highlights various health advantages associated with gardening, spanning both psychological and physical domains.

From a mental health perspective, contact with nature and soil exposure can reduce stress and improve mood. Specifically, exposure to the bacterium Mycobacterium vaccae may activate brain neurons that synthesize serotonin and lower cortisol levels. The practice also offers psychological gratification through the direct connection between a gardener’s actions and their results.

Physically, gardening serves as a form of moderate activity that engages multiple muscle groups, including the core, back, and limbs. Using the Metabolic Equivalent of Task (MET) to measure energy expenditure, scientists note that while light tasks like watering plants fall below the World Health Organization’s recommended moderate intensity threshold, more strenuous activities such as digging garden beds provide significant physical effort.
