Here now is Leah:
At the base of our skull exists the longest and most complex cranial nerve, called the vagus nerve. Picture this nerve like a beautiful climbing rose bush on a fragile bone trellis. It first reaches its delicate tendrils around the face, throat, vocal chords, and neck, then extends down to the heart, lungs, diaphragm, stomach, and intestines. For those of you with more sensitive stomachs, the vagus nerve is like a highway of communication sending signals from the brain, to the gut, and back to the brain— the cause of what we call “gut feelings.” A healthy functioning vagus nerve is said to have a strong “vagal tone.”
Through indirect stimulation of the nerve, vagal tone can be increased by:
- singing or humming,
- slow deep diaphragmatic breathing,
- cold showers or splashing the face with ice water,
- and soothing connection (long hugs are like kale for the nervous system).
How the Vagus rules
...the prime component of the parasympathetic nervous system which regulates the ‘rest-and-digest’ or ‘tend-and-befriend’ responses (while) the sympathetic nervous system drives the ‘fight-or-flight’ response. - Christopher Bergland, Psychology Today
...work in a rhythmic alternation that supports healthy digestion, sleep, and immune system functioning. - Dr. Arielle Shwartz.Additionally, the vagus nerve decreases inflammation and lowers blood pressure. A special note on inflammation: many scientists are beginning to consider conditions like anxiety, depression, and PTSD as forms and byproducts of inflammation. Other inflammatory diseases and conditions that could benefit from stimulation of the vagus nerve include: rheumatoid arthritis, inflammatory bowel syndrome, Crohn’s disease, Parkinson's, and epilepsy.
In 2005, the FDA approved the use of vagus nerve stimulation as a treatment for depression. It has also been found to help with the following conditions: rapid cycling bipolar disorder, anxiety disorders, and Alzheimers Disease” - Stacy Sampson, DO, Medical News Today
The Vagus nerve's impact on the Voice
By focusing on what my body needs physiologically to calm its “wild animal” and shift from the sympathetic to parasympathetic nervous system, I am more able to remove myself from the emotional storm caused by anxiety, and tame the physical manifestations of fear that inhibit my ability to simply sing. - Leah Grams Johnson
Bottom line:Not only does the vagus nerve affect the voice by physically touching the vocal chords, throat, lungs, and diaphragm, it also has a heavy hand in directing the autonomic nervous system. Conversely, the vibration of the vocal chords through singing greatly nourishes this wandering nerve and strengthens vagal tone.
