The vagus nerve is a major pathway that helps the body shift out of fight or flight. It plays a role in breathing, heart rate, digestion, and the ability to feel calm and grounded. When vagal input is reduced, the nervous system can stay stuck in high alert, even at rest.
One key area that influences the vagus nerve is the atlas, the uppermost bone of the spine. It sits just below the skull, near where the vagus nerve exits the brainstem. Gentle chiropractic support at this level can help improve nervous system communication and reduce constant tension.
Breath matters just as much. The vagus nerve is most active during the exhale, and the diaphragm plays a central role in that process. When the diaphragm is tight or restricted, breathing becomes shallow, the exhale shortens, and vagal stimulation decreases.
That’s why we combine chiropractic care and pelvic floor physical therapy.
Treatment may include:
• Gentle chiropractic support of the atlas, the top of the spine
• Diaphragm and rib work with pelvic floor PT to restore full breathing motion
• Breath cueing to encourage longer, unforced exhales
By supporting both the upper spine and the diaphragm, we help restore the physical pathways that allow the nervous system to move out of fight or flight and into regulation.
This isn’t about forcing calm.
It’s about helping the body feel safe again.
