4. Regulates Heart, Breath and Degestion

It slows the heart by releasing acetylcholine, which signals the sinoatrial (SA) node to reduce heart rate, preventing excessive strain. It regulates breathing by adjusting diaphragm contractions, ensuring optimal oxygen exchange and preventing shallow breathing patterns linked to anxiety. In the gut, it enhances motility by stimulating peristalsis, coordinating muscle contractions to move food efficiently, improving nutrient absorption, and preventing issues like bloating or constipation.
