The VAGUS nerve, the “Commander and Chief” of the autonomic nervous system–promotes your fertility, gut, and health!

August 19, 2018

The Vagus nerve is the largest cranial nerve and one of the most powerful nerves in the body. It is a bundle of sensory and motor fibers that power the parasympathetic nervous system. It connects the brain to the heart, lungs, spleen and intestines. It also has branches that travels to the Female Fertility Organs (the uterus, cervix and vagina) besides to the neck, kidney and liver. This parasympathetic nervous system controls our unconscious body functions like breathing, heart rate, digestion, etc.


Sometimes we “feel things” in our gut (good or bad) and it’s because of this vagus nerve–when it is sending messages from the brain to the gut! This is why our “gut instincts” are good to follow. The gut is called the “second brain” because of the vagus nerve. The enteric nervous system (ENS) governs function of the G.I. tract. The ENS connects to the brain via the vagus nerve.


How does the vagus nerve get damaged or stressed? There are a lot of reasons but the most common ones are injuries to the head or neck, accidents, stress, and even diet can interfere with firing of the vagus nerve. The vagus nerve uses the neurotransmitter, acetylcholine (chemical messenger), to communicate with the brain. Studies have shown acetylcholine can be negatively affected by stress and diet.



One of the main purposes of the vagus nerve is to calm down the body. It also helps with the growth and repair of nervous system. Researchers at Oregon University report that daily meditation activates the vagus nerve to create a relaxation respond. Research also points out that auricular (ear) Acupuncture creates a relaxation response and stimulates the hypothalamic pituitary ovarian axis to help with balancing hormones for fertility. Once you know the importance of the vagus nerve below are some exercise and things you can do to keep your vague nerve healthy.
