It brings feelings of calm, optimism, trust and self-esteem. This is due to its effect on our brains, the central nervous system. But Dr. Michael Gershon, author of The Second Brain, explains how oxytocin has a similar effect on the intestinal tract. This is because oxytocin and its receptors are found in the gut, much like another neurotransmitter, serotonin. Thus, supporting digestive and intestinal health is vital to emotional and mental health, and vice versa.
Oxytocin has been found to reduce gastrointestinal inflammation and improve gut motility. It also reduces cortisol levels (the stress hormone) and decreases blood pressure. We know that touch, physical affection, kindness and emotional support raises the level of oxytocin in the body. What this means is that love really is an integral part of healing the physical body.
