There is evidence that a bacteria in the soil called Mycobacterium vaccae may lift spirits. When fed to mice, these seemingly harmless bacteria stimulated their immune system and boosted the production of serotonin. Another study on an experimental treatment for lung cancer found patients who received inoculation of the bacteria had fewer symptoms and improved emotional health. Higher levels of serotonin improve mood. Long-term exposure to M. vaccae from childhood may help build a healthy immune system. It may just be that playing in the dirt does make us happy. theguardian/lifeandstyle/2013/jun/29/alys-fowler-gardening-makes-you-happy?CMP=twt_gu
