225 — Control Your Vagus Nerve to Improve Your Mental and Physical Health With Dr. Kevin Tracey

What if improving your mental health and physical well-being could be as simple as understanding one nerve in your body? Research shows your vagus nerve plays a powerful role in your well-being.
 
This week, I’m joined by Dr. Kevin Tracey, a world-renowned neurosurgeon and pioneering researcher, to explore the vagus nerve and how improving your vagal tone can improve your health.
 
Some of the things we discuss are:
 

• What the vagus nerve is and why it’s crucial for your overall health.
• How vagus nerve stimulation is being used to treat conditions like depression and rheumatoid arthritis.
• Clear signs of vagus nerve dysfunction and how it connects to inflammation.
• Practical ways to improve your vagal tone, from exercise to breath work.
• Why heart rate variability might be a window into your health.
• The critical role the vagus nerve plays in building mental strength and resilience.

Key Takeaways:

• The vagus nerve is a critical communication pathway between the brain and various organs, influencing both physical and mental health.
• Understanding and improving vagal tone through activities like exercise and breath work can potentially reduce inflammation and improve mental resilience.
• There is a strong connection between lifestyle choices, vagal tone, and systemic inflammation, often elucidated by emerging research on vagus nerve function.
• Be wary of over-the-counter devices claiming to stimulate the vagus nerve as most aren’t based on evidence-based approaches.
• Activities like cold exposure and cardio workouts might enhance vagal function, offering potential benefits for both physical and mental health.
