Have you ever wondered why some people seem to bounce back from stress more easily than others? The answer may lie in the strength of their vagus nerve.   In today’s episode of the Longevity Podcast, I chat with Dr. Navaz Habib about the importance of the vagus nerve and its impact on heart rate variability (HRV). He explains that the vagus nerve is a unique nerve that connects the brain to all organs in the thorax and abdomen, allowing for communication and signaling. Vagal tone, which refers to the strength of the signals sent through the vagus nerve, is crucial for optimal health.    Dr. Habib identifies four types of stressors that can affect vagal tone: emotional, physical, biochemical, and psychological. He emphasizes the importance of proper breathing techniques, such as slow, diaphragmatic breathing, to improve vagal tone. We also discuss the role of nitric oxide in supporting vagus nerve function and how to supplement it for overall health.    Dr. Navaz Habib, is a Doctor of Chiropractic and Functional Medicine Practitioner who empowers his clients to dig deeper and find the answers to what is holding back their health, affecting their energy and productivity. He is also the host of The Health Upgrade Podcast and speaks on various topics related to Vagus Nerve and its impact on optimal health.   Thank you to our sponsors for making this episode possible: Fatty15: Visit http://fatty15.com/NAT  and use promo code NAT to save.
