Gardening makes you happy thanks to bacteria

The taste for gardening already has its scientific explanation. The reason we are happy taking care of our plants is bacteria.

Despite the fact that we are increasingly away from it, contact with nature is vital for human happiness. Its benefits include the practice of exercise, socialization or exposure to natural light. There is a clear connection between good mental health and having grown up in a rural area, surrounded by green areas.

The scientific explanation

The University of Colorado discovered a bacteria that has effects in people with depression. His name isMycobacterium vaccae, a non-pathogenic bacteria that can be found in soil.

This bacterium markedly increased serotonin and norepinephrine levels in the brain of mice according to the study. The effect of the bacteria is equivalent to drugs such as Prozac, commonly used to control depression. Contact with the earth would be, in conclusion, a natural antidepressant.

The benefits of the bacteria also included anti-stress effects. Not only a higher tolerance, but also a slower response to it.

It has also been used in studies related to chemotherapy, improving the quality of life of patients. The bacteria fought nausea and pain, improving your immune system thanks to certain anti-inflammatory effects.

Lowry and his team have presented in their studio"Identification and characterization of a new anti-inflammatory lipid isolated from Mycobacterium vaccae, a soil-derived bacterium with immunoregulatory and stress resistance properties" confirmation of the qualities of the bacteria: a 10 (Z) -hexadecenoic fatty acid.

By isolating this fatty acid, it will be possible to use it as a vaccine to make the cells immune to inflammation.

"It seems that these bacteria, with which we coevolve, have a trick up their sleeve," Lowry said. "When they are absorbed by immune cells, they release these lipids that bind to this receptor and close the inflammatory cascade ...

This is just one strain of one species of a type of bacteria found on earth, but there are millions of different strains in soils. We are only just beginning to look at the tip of the iceberg, in terms of identifying the mechanisms by which they have evolved to keep us healthy. This should inspire us fear ”.
