FORGET the spring-cleaning. A study has found evidence that bacteria common in soil and dirt could improve people's spirits.
According to the research, the action of Mycobacterium vaccae (M vaccae) on the brain is similar to that of some commonly used antidepressants.
The bacterium, which is related to the microbe that causes tuberculosis, appears to work by stimulating the body's immune system. This, in turn, prompts certain cells in the brain to produce more serotonin, a hormone associated with feelings of wellbeing.
“These studies help us to understand how the body communicates with the brain and why a healthy immune system is important for maintaining mental health,” said Dr Chris Lowry, a neuroscientist at Bristol University who carried out the research.
“They also leave us wondering if we shouldn't all spend more time playing in the dirt.”
Unless of course it is an April Fool . . .
