Dr. Navaz Habib | How to Activate Your Vagus Nerve and Heal Inflammation

June 18, 2025

In this episode of the Smarter Not Harder Podcast, Dr. Navaz Habib gives us one-cent solutions to life’s $64,000 questions that include:

  • What is the physiological role of the vagus nerve in regulating inflammation and autonomic balance?

  • How can vagal tone be measured, and what does it reveal about an individual's resilience and health status?

  • What is the relationship between HRV, respiratory rate, and tools like the BOLT score in assessing nervous system function?

  • How do interventions such as nutraceuticals, peptides, psychedelics, and breathing techniques support vagus nerve activation and neuroplasticity?

Who is Dr. Navaz Habib?

After years of watching patients cycle through his practice, Dr. Navaz Habib noticed a pattern. While his patients struggled with a wide range of conditions, they all suffered from the same core problem: they were unable to control inflammation.

When we think about health, we tend to think about diseases and diagnoses, but in reality, it comes down to inflammatory control. As the body’s most unique nerve, the vagus nerve actually determines everything about the trajectory of health and disease. Many of the conditions Dr. Habib’s patients were experiencing were actually due to the lack of vagus nerve signaling to control inflammation.

Now, Dr. Habib offers an easy-to-follow nutrition, lifestyle, and self-care program anchored in evidence and pioneering research that teaches you how to optimize vagus nerve function, no matter your age or health background.
