We know that just by being in nature there is a restorative benefit however now research have also found that the direct contact that we have with the soil when we make garden work can actually also benefit us. It is described liked this at the blog: “It’s in the dirt. Or to be a little more specific, a strain of bacterium in soil, Mycobacterium vaccae, has been found to trigger the release of seratonin, which in turn elevates mood and decreases anxiety. And on top of that, this little bacterium has been found to improve cognitive function and possibly even treat cancer and other diseases. Which means that contact with soil, through gardening or other means, is beneficial.”
I guess you are curious to know more about how and why so I recommend that you read the rest of the article at the Therapeutic Landscape Network blog. It is really well written and easy to understand.
The research is also discussed in The Economist.
At the image you see 3 of my classmates on a Summer camp in sixth grade, many years ago. No doubt that they were happy.
