The healing nature of a garden is actually an ancient concept. The famous Hanging Gardens of Babylon were built by King Nebuchadnezzar to comfort his homesick wife, Amyitis. From Japanese Zen gardens to medieval monastic gardens to modern therapy gardens, the healing power of nature has long been recognized in the form of gardening.
What is it about gardening that makes it so effective at lifting the spirits? What form does gardening take today?
Good Dirt
There is bacteria that lives in soil called mycobacterium vaccae. Interestingly, exposure to this bacteria has been shown to enhance cognitive function, perhaps by stimulating brain cells to produce serotonin. It is the brain level of this chemical that determines mood and mental function. In fact, low levels of serotonin are present in people with Obsessive-Compulsive Disorder (OCD), depression, bipolar disorder, and other emotional and mental disorders. Getting your hands in the dirt exposes you to this beneficial microbe, and may play a part in the happy effects of gardening.
