Struggling With Mystery Symptoms? An Expert Explains Why Your Vagus Nerve May Hold the Key and How to Fix It with Dr. Navaz Habib

This podcast interviews Dr. Navaz Habib about the vagus nerve, its function, and how to improve its health. The discussion covers the vagus nerve's role in bodily functions, common signs of dysfunction (digestive issues, inflammation, mental health challenges), and the four main stressors that damage it (daily, psychological, physical, and biochemical). Dr. Habib emphasizes using wearable technology to track heart rate variability (HRV), respiratory rate, and sleep architecture as proxies for vagus nerve health, illustrating with patient data. He suggests prioritizing sleep and implementing daily routines ("bookending the day") to improve vagus nerve function. Finally, he recommends nasal diaphragmatic breathing with longer exhales, practicing gratitude, and spending time with loved ones to enhance vagal tone.
