The passage discusses how exposure to Mycobacterium Vacce, a type of bacteria in soil, can increase serotonin levels in the body, boost mood, decrease anxiety, and potentially enhance cognitive ability. The presence of certain microbes in our bodies is also essential to our health, assisting in digestion, nutrient production, protection from pathogenic microbes, and immune functioning.
The passage discusses the properties and effects of a type of bacteria called Mycobacterium Vaccae. This bacteria, which exists in soils, can evidently increase the levels of serotonin, a brain chemical that positively affects mood and decreases anxiety. Some studies showed that the bacteria improved cognitive ability and reduced anxiety in mice, suggesting that it could have similar impacts on humans. The information also indicates that the presence or absence of certain microbes can affect the proper functioning and health of our bodies.
It's fascinating to learn that bacteria can increase the fertility of soils, transform plant substances into humus, and produce substances such as antibiotics. An interesting point is that low levels of these antibiotics in the environment can cause bacteria to mutate and become antibiotic-resistant.
Our bodies also host microbes that assist in digestion, nutrient production, protection from pathogenic microbes, and immune training. The equilibrium of these microbes is essential for our health, and the disruption of this balance can lead to illnesses and other health complications. Therefore, exposure to beneficial bacteria like Mycobacterium Vaccae may be crucial for maintaining a healthy internal ecosystem.
