Heres one I bet no one added, lol



Twenty pages into What's Your Poo Telling You?, I came across a funny description of a type of bowel movement the authors called "Poo-phoria". This bowel movement causes a person to experience euphoria and ecstasy as they pass a very large stool. The authors explain that "poo-phoria" usually leads to a feeling of exhilaration, intense relaxation, and even goose bumps. It's generally a very safe way to feel "high." though some people can get addicted to the experience.

The authors further state that the "high" feeling comes from stimulation of the vagus nerve, which is the tenth of twelve cranial nerves. As a very large bowel movement passes through the rectum, the vagus nerve fires. When the vagus nerve is stimulated, it usually causes a sudden drop in blood pressure and heart rate. Mild stimulation of the vagus nerve produces that "high" Richman and Sheth write about in their description of "Poo-phoria". However, if the vagus nerve is more intensely stimulated during a bowel movement, it can lead to what's known as defecation syncope.
