Playing dirty
Digging, weeding and planting may lift your mood in more ways than you know, say scientists
Friendly bacteria found in soil may have the same mood-boosting effects as common antidepressants, according to new research carried out at Bristol University. The findings, published in the journal Neuroscience, found that mice treated with the soil bacteria appeared more relaxed.
The study revealed that the bacteria, Mycobacterium vaccae, stimulated the immune system and activated brain cells to produce more serotonin, the mood-enhancing brain chemical. A lack of serotonin is associated with depression. Some types of antidepressants work by increasing amounts of serotonin in the brain.
The scientists became interested in the project when they heard that cancer patients treated with the bacterium Mycobacterium vaccae reported increases in their quality of life. They speculated this could be because the bacteria were activating brain cells to release more serotonin
Dr Chris Lowry, lead author said "These studies help us understand how the body communicates with the brain and why a healthy immune system is important for maintaining mental health. They also leave us wondering if we shouldn't all spend more time playing in the dirt."
