Gardening has been found to have many health benefits and is beneficial in reducing symptoms of anxiety and depression.
So getting your hands dirty in the garden can increase your serotonin levels. This is due to a specific soil bacteria, Mycobacterium vaccae, that can trigger the release of serotonin in our brain. Serotonin is a natural anti-depressant that can make you happy. A lack of serotonin in the brain causes depression and anxiety.
