The vagus nerve is a primary carrier of information describing the state of the body to the brain, and transmitting information from the brain back to the body. It’s a feedback mechanism which is responsible for maintaining homeostasis for many of our vital organs and brain/body functions. Research over the past few decades shows that the vagus plays a key role in managing our levels of stress as well as our body’s inflammation; in this age of stress- and inflammation-related disease, it is perhaps the most important nerve in the body for us to be paying attention to.
