What the wellness community recommends for stimulating the vagus nerve—eye movements, meditation, massage, cold-water immersion, and singing and humming—, if it works, is likely to be beneficial through a very simple concept: relaxation.
Loud gargling with water or loud singing activates our vocal cords which in turn stimulates the vagus nerve. Foot massage: gentle or firm touch can assist in stimulation the vagus nerve. Cold water face immersion: immerse your forehead eyes and at least 2/3 of both cheeks into cold water.
Aim to get in five minutes a day, throughout the day of the below vagus nerve exercises.
Sleep on the right side
Lying on the back decreases Vagus Nerve activation, but sleeping on the right side shows greater Vagus Nerve stimulation compared to left side sleeping.
Eat foods rich in tryptophan.
Dietary tryptophan is metabolized in the gut and may help the astrocytes—cells in the brain and spinal cord—control inflammation, which may improve communication from the gut to the brain via the vagal messenger pathway. These foods include spinach, seeds, nuts, bananas, and poultry.
Drinking water is also a stimulus to the vagus nerve, and may immediately stop a run of supraventricular tachycardia. Not having enough fluid (what people think of as “dehydration”) is another stimulus for fast heart rates, so some additional fluid is a second reason that water may help, though not instantly.
The vagus nerve can become damaged for various reasons, including stomach or oesophagal surgery and type-2 diabetes. Symptoms of damage include hoarseness of voice, a deficient gag reflex and difficulty swallowing. Besides these symptoms, vagal damage can manifest itself through digestive issues.
There are two main causes of vagus nerve dysfunction: previous infection or inflammation and physical or psychological stress.
Singing, Humming, Chanting and Gargling
The vagus nerve is connected to your vocal cords and the muscles at the back of your throat. Singing, humming, chanting and gargling can activate these muscles and stimulate your vagus nerve. And this has been shown to increase heart-rate variability and vagal tone (12).
The left vagal nerve runs down the left side of your neck, and the right vagal nerve runs down your right side. This nerve extends all the way from your brain to the large intestines: down your neck, through your chest, around your heart, around your lungs, and through your abdomen and intestines.
Something calming and easy that's not vigorous, like taking a walk, is a great way to destress and also help your vagus nerve. People who engage in regular walks see a significant reduction in anxiety and perceived stress, as well as a better overall mood and physical health.
“You can do things like yoga and deep breathing exercises. Those indirectly stimulate the vagus nerve by stimulating other organs the vagus nerve innervates,” says Howell. “Another interesting one is loud gargling with water or singing, both of which stimulate the vocal cords, which then stimulate the vagus nerve.
There are a bunch of benefits of stimulating your vagus nerve: headache & migraine relief; reducing stress & anxiety; improving your digestion; reducing inflammation.
MASSAGE. You can manually stimulate the vagus nerve by massaging certain areas of the body. A neck massage along the carotid sinus, the right side of your throat, stimulates the vagus nerve. Foot massage can also increase vagal modulation, as well as help lower blood pressure.
This particular technique involves tapping different parts of the chest to stimulate the vagus nerve and balance our autonomic nervous system. There are a few YouTube videos that demonstrate how to perform vagus nerve tapping, but there is very little information regarding the science or evidence behind the technique.
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.
However, chronic stress can impact the vagus nerve in a negative way. 2 This can lead to problems such as anxiety and depression. It can also make the body more susceptible to infections and diseases. 3 Therefore, it is important to manage stress in order to maintain a healthy vagus nerve.
Your vagus nerve is connected to your vocal cords, the muscles at the back of your throat and passes through your inner ear. Try humming or singing or just listening to calm, soothing music. Those sounds and vibrations may stimulate your vagus nerve.
