Your gut and its brain connection, ....good article. Happy gut = happy brain. Many lacking brain "calmness" have some gut issue, coincidence?, not.
I did see an article once that noted many people in the dark winter northern states have more gut issues in the winter. Well, they also get less serotonin (happy gut-brain hormone) in the winter. Even though some serotonin is made in the gut, it also needs some from your brain, ..............sunlight.
Now that I think of it, my gut was always best in the summer extended day light.
This self hacked guy puts a lot of body mystery together, sometimes with flaws (candida is yeast, not bacteria), but its rare to see this all written together.https://www.selfhacked.com/blog/causes-ibs-general-gut-dysfunction/
