However, the brilliant minds of our world are still searching for the why of how: and how the Big Bang took place, and is there a life elsewhere in the universe …. Imagine that researchers have discovered in two stages (2007 and 2010) why working in the garden made you happier and, above all, smarter. Personal note: some politicians should garden a little more they would serve the country …
So according to these researchers, the credit goes to one of the smallest organisms living on earth, namely a bacterium. The latter is called mycobacterium vaccae and is best known for being the source of tuberculosis. It is found in the soil of your garden but no panic is a harmless strain.
Put your hands in the ground
Experiments in mice have shown that contact with the bacterium increases the brain’s production of serotonin, the latter being considered as the “happiness hormone”. Serotonin is actually a neurotransmitter, a chemical molecule that transmits information between neurons. Its weak presence in the brain is one of the symptoms of depression. This study was conducted by Dr. Chistopher Lowry in 2007.
But in 2010, Sage College in New York is back by publishing a study showing that M. vaccae improves learning while reducing anxiety. Professor Dorothy Matthews’ experiment, still on mice, found that the ingestion of the bacteria allowed them to get out of a labyrinth faster (2X faster) and less stressed than the control group (untreated).
The exact mechanism for these feats is not (yet) known but know that it is useless to eat the land because the mere breath of dust or wet particles from the soil is enough to bring the bacteria into the soil. ‘organization….
The funny conclusion is that too much hygiene (killing bacteria) makes you stupid and depressed !!!
