In this episode, I’m joined by Dr. Navaz Habib, often known as The Vagus Nerve Doc, to talk about why the vagus nerve has become such an important part of the modern health conversation. We get into what the vagus nerve actually is, where it runs in the body, and why it matters so much when it comes to stress, inflammation, recovery, sleep, gut health and overall nervous system balance. Dr. Habib shares how his own early health struggles led him into functional medicine and eventually to a much deeper understanding of the vagus nerve and its role in helping the body regulate and recover. We talk about what low vagal tone can look like in real life, from poor sleep and digestive issues to anxiety, low HRV and feeling like your body is stuck in overdrive. We also explore the connection between the vagus nerve and HRV, how age and perimenopause can affect the nervous system, and why simple daily practices like breathwork can be one of the most effective places to start if you want to improve resilience and recovery. Dr. Habib also shares his VAGUS Protocol and explains how he approaches supporting the nervous system through validation, activation, gut brain immune support, reducing stress burden and building habits that are actually sustainable. This is a really helpful episode if you are interested in nervous system regulation, stress resilience, better sleep, gut health, recovery, HRV, menopause, or practical tools that can help you feel calmer and more regulated in everyday life. In this episode, we cover what the vagus nerve is and why it matters, the signs of vagus nerve dysfunction, the link between vagal tone and HRV, how stress, trauma, toxins and physical strain can affect the nervous system, the connection between the vagus nerve, gut health, inflammation and immunity, why low vagal tone may be linked to anxiety and poor sleep, and how breathwork, humming, cold exposure, sauna and movement can all support vagus nerve function. One of the biggest takeaways from this conversation is that stress itself is not always the problem. The bigger issue is often our capacity to respond to it. Dr. Habib explains how improving vagal tone may help the body shift out of a chronic fight or flight state and into a more restorative state where healing and recovery can actually happen. His biggest recommendation for anyone wanting to get started is simple. Start with the breath.
