VAGUS BABY!
The vagus nerve is the tenth cranial nerve and is the longest of the 12 cranial nerves serving as the bodyâs superhighway, carrying information between the brain and internal organs. It links the brainstem to the heart, lungs and gut.
The long wandering nerve has multiple branches that interact with the pharynx, larynx, heart, esophagus, stomach, small intestine and large intestine, liver, spleen, gallbladder, and kidneys. It plays a role in functions like heart rate, digestion, excretion and even plays a role in taste, swallowing and speech. Polyvagal theory (last post) recognizes that both branches of the vagus nerve calm the body but in different ways.
The ventral branch affects body functioning above the diaphragm. When we are in the ventral branch of the parasympathetic, we are socially engaged also referred to as ârest and digest.â In this state we feel grounded, safe, and able to connect with others.
The dorsal vagal branch affects the body below the diaphragm and is involved with digestive issues. When we are in dorsal vagal, we are in the freeze response and shut down, become immobile or dissociate. This might look like low energy, feeling depressed, not wanting to socialize, feeling numb and disconnected from our body.
Luckily, you can activate your vagus nerve. By stimulating the vagus nerve *regularly* you are increasing vagal tone by sending the message that itâs time to relax.
