The Wandering Nerve

There is an interesting article about the vagus nerve in the June 2 NY Times. It tells how studies continue to show that “good vagal tone” can help treat a range of problems including depression, anxiety, epilepsy, diabetes, PTSD, as well as inflammatory autoimmune issues like rheumatoid arthritis, and maybe even long-haul Covid.

The vagus nerve is a long bundle of nerves that runs from the cranium down, and picks up information from the heart as well as the other internal organs, including the digestive system. Its name comes from the Latin word for “wander” because it wanders and connects to so many different body parts.  When toned, the vagus nerve produces acetylcholine, the chief neurotransmitter of the parasympathetic (rest, digest, heal) nervous system. It dilates blood vessels, increases bodily secretions, and slows heart rate.

The Times article discusses a new electric device that can, for a very steep price, be implanted in one’s neck, stimulating the vagus nerve. The article then mentions, almost as a casual aside, how “mindfulness, exercise and paced breathing” also tone the vagus nerve. In fact (this from Psychology Today magazine) “Deep diaphragmatic breathing—with a long, slow exhale—is key to stimulating the vagus nerve and slowing heart rate and blood pressure, especially in times of performance anxiety.” No buzzing electronic neck implants necessary!

Qigong is rooted in the practice of deep, relaxed breathing. Mindful, slow breathing smooths the connections between brain and body, and supports the work of the vagus nerve. I will incorporate into our classes several simple, relaxing, and energizing breathing practices that are particularly good for toning this important nerve. Please join me!
