The Vagus Nerve Miracle: 7 Simple Ways to Support Your Body’s Calm Superhighway

By Nisarga Eryk Dobosz · 21 July 2025

The vagus nerve, the longest cranial nerve in the body, is often called the “wandering nerve” because of its extensive reach, connecting the brain to nearly every major organ. But it is far more than a passive messenger. It is the main pathway of the parasympathetic nervous system, the branch responsible for rest, digestion and relaxation, and it plays a role in heart rate, digestion and emotional resilience. When it works well, it supports a state of calm, balance and well-being. Modern life, with its stress, poor posture and shallow breathing, can lower vagal tone. The good news: there are simple, everyday practices that support it.

What the vagus nerve does

The vagus nerve is the tenth cranial nerve (CN X) and a key part of the autonomic nervous system, which runs involuntary functions like heart rate, digestion and breathing rate. It is the primary pathway of the “rest and digest” system, which counterbalances the “fight or flight” response of the sympathetic nervous system.

Research links higher vagal tone, a measure of vagus nerve activity, with better emotional regulation, healthier inflammatory responses and better gut function, and even with feeling more socially connected. Lower vagal tone has been associated with anxiety, low mood and digestive complaints. The vagus nerve is also part of the gut-brain axis, carrying messages between the gut and the brain, which is why it is sometimes called the “gut-brain superhighway”.

One fascinating aspect is its use of acetylcholine, a neurotransmitter that helps calm the nervous system and is involved in regulating inflammation. This is one reason vagus nerve research is such an exciting field.

7 exercises to support your vagus nerve

These practices are simple, gentle and easy to fit into your day. Start slowly and listen to your body.

1. Deep diaphragmatic breathing. The vagus nerve is closely connected to the diaphragm, your main breathing muscle. Sit or lie down with one hand on your chest and one on your belly. Inhale through the nose for 4 counts so the belly rises, then exhale slowly through the mouth for 6. Repeat for 5–10 minutes. Studies show that slow, rhythmic breathing increases heart rate variability (HRV), a marker of vagal tone.
2. Humming or chanting. The vagus nerve passes by the vocal cords and the muscles at the back of the throat. Choose a simple sound like “Om” or “Ah”, close your eyes and hum or chant for 5–10 minutes, feeling the vibration in your throat and chest. Humming also lengthens the exhale, one of the simplest ways to invite calm.
3. Brief cold exposure. At the end of your shower, turn the water to cold for 30–60 seconds, slowing your breath and relaxing your body. Research suggests brief cold exposure can increase parasympathetic activity. Go gently, and skip it if you have a heart condition or are unsure, and check with your doctor first.
4. Yoga and gentle movement. Poses that combine gentle stretching with deep breathing, such as child’s pose, cat-cow and legs-up-the-wall, are a lovely way in. Spend 10–15 minutes a day, synchronising breath with movement. Studies show yoga can increase HRV.
5. Laughter and social connection. Laughter and warm social contact send powerful signals of safety. Spend time with loved ones, watch a funny film or do something that brings you joy.
6. Ear massage. The auricular branch of the vagus nerve reaches the outer ear. Use your fingers to gently massage the outer ear, focusing on the earlobe and the ridge behind it, for 2–3 minutes on each side.
7. Gentle touch and myofascial release on the neck. The vagus nerve travels through the neck, and tightness in the neck and shoulders is a common sign of stress. Use your fingers or a soft ball to apply gentle pressure to the sides and back of the neck and the base of the skull, holding tender spots for 20–30 seconds while you breathe deeply. Myofascial release can reduce muscle tension and invite relaxation. This kind of listening touch is at the heart of our MER® training.

The vagus nerve and emotional resilience

The vagus nerve is not just a physical pathway. It is deeply intertwined with our emotional life. Higher vagal tone is associated with greater emotional resilience, helping us recover more quickly from stress, and it is part of the system that settles the stress response and supports feelings of safety and connection.

The vagus nerve is truly a marvel of the human body, a bridge between the physical and the emotional, the mind and the body. By nurturing it with simple daily practices, you support your body’s own capacity for balance. Breath is one of the most direct ways in, and it is the foundation of our BBTRS® training.

Embrace the vagus nerve miracle

Whether through deep breathing, humming, a splash of cold water or a good laugh, each practice brings you a little closer to calm, connection and vitality. The vagus nerve reminds us that well-being is not only about treating symptoms but about nurturing the body’s innate wisdom. So take a deep breath, hum a tune or share a laugh. Your vagus nerve will thank you.
