In this podcast episode, James Maskell interviews Dr. Navaz Habib about the importance of the vagus nerve in healing and overall health. Dr. Habib explains that the vagus nerve plays a critical role in shifting the body from a sympathetic (fight or flight) state to a parasympathetic (rest and digest) state, which is necessary for healing. He emphasizes the importance of creating a safe and supportive environment for patients to feel connected and reduce stress. Dr. Habib also discusses the role of physical trauma, such as head injuries or spinal misalignments, in affecting vagus nerve function. He recommends various strategies to improve vagus nerve tone, including diaphragmatic breathing, gargling, humming and physical exercise. Dr. Habib's new book, Upgrade Your Vagus Nerve, provides further information on these strategies and their impact on overall health. Listen to the full conversation to learn how: The vagus nerve is the organ of unity, connecting all organs and systems in the body. Chronic diseases are diseases of disconnection, both internally and externally. Breathing exercises, such as slow, nasal and diaphragmatic breathing, can help regulate the breath and shift the body into a parasympathetic state. Gargling, humming and vocalization can stimulate the vagus nerve and activate the parasympathetic system. The vagus nerve is a unifying topic for health professionals and can be beneficial for patients of all ages and conditions.
