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.Read the episode show notes at hubermanlab.com.Thank you to our sponsorsAG1: https://drinkag1.com/hubermanLMNT: https://drinklmnt.com/hubermanJoovv: https://joovv.com/hubermanROKA: https://roka.com/hubermanFunction: https://functionhealth.com/hubermanTimestampsDisclaimer & Disclosures Learn more about your ad choices.
