I’ve been reading up a lot about the vagus nerve in the last few years and it does seem to be critically important for wellness. One reason that is so, is because it is the longest nerve in the body, running from the brain down to and wrapping around the various digestive organs. (This nerve lives up to its name. ‘Vagus’ is Latin for ‘wandering’.) Just from its location, we can surmise that the vagus nerve influences a number of bodily functions.
I found the article entitled How to Control Inflammation with Your Brain to be a simple and straightforward explanation of how to unlock the power of the vagus nerve for your own self-healing.
To the suggestions cited in the article, I would add reflexology. There is a reflex for the vagus nerve on both of the feet and one that smart reflexologists will want to give a little more attention to during their sessions.
