Acupuncture and The Vagus Nerve
The vagus nerve, which is the longest cranial nerve in the body, plays an important role in regulating various bodily functions including heart rate, digestion, and respiration. It is also involved in the regulation of emotional and psychological responses. It also controls certain reflex actions like gagging, swallowing, coughing, and vomiting.
Acupuncture helps to balance the nervous system, which in turn leads to better health. A regulated nervous system can reduce pain and inflammation, and improve things like sleep and digestion.
Acupuncture has been shown to have a beneficial effect on the vagus nerve, and can be used as a complementary therapy to enhance its function. In this article, we will explore the connection between acupuncture and the vagus nerve, and how acupuncture can be used to stimulate and regulate its activity.
About the Vagus Nerve
The vagus nerve (not vegas nerve, although it is pronounced like vegas from Las Vegas), also known as the 10th cranial nerve, is the longest nerve in the body, running from the brainstem all the way down to the colon. It is composed of both sensory and motor fibers, and has multiple branches that innervate various organs throughout the body.
The vagus nerve plays a crucial role in regulating many bodily functions, including digestion, heart rate, breathing, and immune function. It is a major component of the parasympathetic nervous system, which is responsible for the body's "rest and digest" response, as opposed to the "fight or flight" response of the sympathetic nervous system.
Activation of the vagus nerve can promote relaxation, decrease heart rate, increase digestion and nutrient absorption, and improve immune function. Dysfunction or damage to the vagus nerve can lead to a variety of symptoms, including digestive issues, heart problems, and immune system dysfunction.
According to the Journal of Clinical Medicine, research has linked reduced vagus nerve activity to non-communicable conditions like cardiovascular diseases, cancer and chronic obstructive pulmonary disease.
"Vagal nerve activity is related to frontal brain activity which regulates unhealthy lifestyle behaviors. Epidemiologically, high vagal activity, indexed by greater heart rate variability (HRV), independently predicts reduced risk of GBD (global burden of diseases) and better prognosis in GBD. Biologically, the vagus nerve inhibits oxidative stress, inflammation and sympathetic activity (and associated hypoxia)."
The vagus nerve has been found to help modulate communication between the brain and gastrointestinal tract ( the “brain-gut axis”). It helps activate the parasympathetic nervous system, the “rest and digest” part of the nervous system. This balances the sympathetic, or “fight or flight” part of the nervous system.
Vagus Nerve Stimulation
The vagus nerve can be stimulated through various methods, including electrical and manual stimulation. Electrical vagus nerve Stimulation (VNS) is a medical treatment that uses a device implanted in the body to send electrical impulses to the vagus nerve. This treatment is commonly used for epilepsy, depression, and other neurological disorders.
Manual vagus nerve Stimulation techniques can also be used to stimulate the nerve. These techniques include breathing exercises, meditation, and acupuncture. Acupuncture is a form of Traditional Chinese Medicine that involves the insertion of fine needles into specific points on the body to stimulate the flow of energy and promote healing.
Vagus nerve Stimulation can also be done at home through techniques such as deep breathing, gargling, humming, and cold exposure. These techniques have been shown to activate the vagus nerve and promote relaxation, reduce inflammation, and improve mood.
While VNS is a medical treatment that should be administered by a healthcare professional, manual and at-home vagus nerve stimulation techniques can be done safely and easily on your own. However, it is important to consult with a healthcare provider before trying any new therapies.
Vagus Nerve Reset with Acupuncture
How does acupuncture stimulate the vagus nerve?
Acupuncture involves the insertion of thin needles into specific points on the body, which can stimulate the vagus nerve. By activating these specific points, acupuncture can regulate the activity of the vagus nerve, promoting its function and increasing its activity. Acupuncture also promotes the release of neurotransmitters and hormones, which can further enhance vagus nerve function. This can help to to promote vagus nerve reset and nervous system balancing.
One study showed that acupuncture can stimulate the vagus nerve to promote anti-inflammatory effects on the body.
“The present study provides evidence that AS (acupuncture stimulation) transmits signals into the vagus nerve and mediates anti-inflammatory responses in the spleen. Using an animal model of acute inflammation, we found that AS attenuated inflammatory responses as measured by TNF-α productions in the serum and the spleen. Removal of vagal and splenic nerves significantly abrogated the anti-inflammatory effects mediated by AS.”
Auricular acupuncture (ear acupuncture) is a form of acupuncture that involves needling specific points on the ear, and several of these points are believed to stimulate the vagus nerve. One study found that auricular acupuncture can provide vagal regulation through the auricular branch of the vagus nerve to affect both the autonomic and central nervous systems. It also concluded that auricular acupuncture may have potential in preventing neurodegenerative diseases by regulating the vagal system.
Acupuncture Points for Vagus Nerve Stimulation
Several acupuncture points can be used to stimulate the vagus nerve:
Conception Vessel 12 (CV 12) – Located on the midline of the abdomen, CV 12 is used to stimulate the vagus nerve, promoting digestion and relaxation.
Conception Vessel 17 (CV 17) – Located in the center of the chest, CV 17 can help regulate the vagus nerve, improving respiratory function and reducing stress.
Heart 7 (HT 7) – Located on the wrist, HT 7 is a powerful point for stimulating the vagus nerve, promoting relaxation and reducing anxiety.
Stomach 36 (ST 36) – Located on the leg, ST 36 can help regulate the vagus nerve, promoting digestion and reducing stress.
Pericardium 6 (PC 6) - located on the inner wrist, this point has been found to activate the parasympathetic nervous system and increase vagal activity.
Lung 7 (LU7) - located on the wrist, this point is said to have a calming effect on the mind and stimulate the vagus nerve.
Governing Vessel 20 (GV 20) - located on the top of the head, this point is believed to help regulate the autonomic nervous system and promote relaxation.
Stomach 9 (ST 9) located on the neck, below the Adam's apple and between the two carotid arteries. this point can help to calm the mind, alleviate pain, and benefit the throat.
Auricular points – The ear has a number of points that can stimulate the vagus nerve, including the cymba conchae, the tragus, and the cavum conchae.
The effects of these acupuncture points in relation to the vagus nerve include regulating the autonomic nervous system, reducing inflammation, improving digestion and immune function, promoting relaxation, and reducing anxiety and stress.
It's important to note that while these points are commonly used in acupuncture for vagus nerve stimulation, the effectiveness may vary depending on the individual and the specific condition being treated. It's always best to consult with a licensed acupuncturist for a personalized treatment plan.
