Why is it that when we’re excited or scared, we can desperately need the toilet? Is it some sort of evolutionary defence mechanism?
In: Biology
Stressful situations release adrenaline and other hormones, which prep the body for fight or flight as has been said. When looking at our human species evolution as a whole, for most of history, people didn’t eat every day, and certainly not 3 times a day. Digestion is really low on the priority list when we’re talking about pre-historic humans that were being hunted by predators and fighting with other tribes constantly. So when you have to fight or run, blood is pulled away from things like digestion and your stomach and other non-essential things to give more energy and blood to your muscles and heart so you can run or fight.
