The vagus nerve may be one of the most important and least understood parts of the human body. As a pioneer of vagus nerve research, Dr. Kevin Tracey joins Dan Harris to unpack the cutting-edge science behind how this remarkable nerve regulates our physical and emotional health, and what we can actually do about it.
Key takeaways include:
- Vagal Tone and Why It Matters: Higher vagal tone is associated with better heart health, greater emotional resilience, and a stronger ability to recover from stress. It is a measurable marker of how well our nervous system is functioning.
- Inflammation as a Key Target: Dr. Tracey’s research reveals how the vagus nerve directly influences the body’s inflammatory response, opening new possibilities for treating chronic illness and improving long-term health.
- Practical Ways to Strengthen the Vagus Nerve: The conversation explores evidence-based strategies for increasing vagal tone through everyday practices that support nervous system regulation.
