The vagus nerve is the longest cranial nerve in your body, running from your brainstem all the way down to your abdomen. It is the primary nerve of the parasympathetic nervous system, responsible for switching your body from "fight or flight" mode into "rest and digest" mode.
When your vagus nerve has good tone (also known as high vagal tone), your body can recover from stress faster, your heart rate is more stable, digestion improves, and inflammation is reduced. Low vagal tone is linked to chronic anxiety, depression, digestive issues, and poor stress resilience.
Research shows that you can strengthen vagal tone through targeted exercises:
NerveCalm puts all of these techniques into a guided, easy-to-follow app so you can build vagal tone in just a few minutes a day.
