“Deep breathing is one way you can voluntarily stimulate your own vagus nerve. Try it now. Take a deep diaphragmatic breath by imagining you are inflating the lower portion of your lungs near your belly button like a balloon, followed by a gradual exhalation as you pull in your belly button. Aim to inhale through your nose this way for a count of three, then exhale slowly through your mouth for a count of 7. .......You are on your way to enhancing the quality of your life.” Deep BreathVagus NerveEnhance Your Quality Of Life Book:The Great Nerve: The New Science of the Vagus Nerve and How to Harness Its Healing Reflexes Source: The Great Nerve: The New Science of the Vagus Nerve and How to Harness Its Healing Reflexes
