Show Notes
In this episode I explain how your vagus nerve—an extensive neural pathway linking your brain and body in both directions—powerfully regulates your mood, digestion, alertness and even certain food cravings, and I explain how you can activate certain vagus nerve pathways to improve your heart rate variability (HRV), a key marker of health and longevity. I also explain how to control vagal pathways to enhance your focus and alertness to improve learning and neuroplasticity. And I explain how your vagus nerve controls levels of serotonin in both your gut and brain, impacting your mood and emotional resilience and how to keep that pathway robust.
