The vagus nerve does not get much attention, but it plays a central role in how your body functions day to day. It helps regulate digestion, inflammation, heart rate, mood, and your ability to shift out of stress. When it is working well, the nervous system feels more flexible and resilient. When it is not, symptoms often feel scattered, persistent, and hard to connect.
That is why we put together a clear, research-grounded guide to help you understand what the vagus nerve does and how to recognize signs it may need support.
