(STUDY FINDS) -- DALLAS — Positivity isn’t always easily achieved, but a new study provides yet another reason we should all do our best to inject a bit of optimism into our mindsets. Researchers from the UT Southwestern Medical Center have found evidence that serotonin, the brain chemical responsible for feelings of happiness and well being, may be able to stop harmful intestinal pathogens from causing deadly infections.
Essentially, the study indicates that happiness can protect against serious gut infections.
Serotonin is almost always thought of as a brain chemical, but about 90% of it is actually produced in the gastrointestinal tract. There’s also trillions of bacteria living in the stomach as well, and while the vast majority of those bacteria are good and beneficial, some pathogenic bacteria also make their way to the gastrointestinal tract. When this happens, it can lead to serious and sometimes fatal gut infections.
