The Role of the Vagus Nerve in Yoga Practice

When you read the word "wanderer," what comes to mind? Perhaps a traveler, moving freely from place to place. But did you know that the word vagus in Latin means "wanderer"? It’s a perfect name for the vagus nerve, which winds its way from the brainstem through the body, connecting to vital organs like the heart, lungs, and digestive system. This nerve does more than just wander—it’s essential for regulating your body’s relaxation response.

Our body’s “wanderer” works hand-in-hand with the parasympathetic nervous system, often referred to as the “rest and digest” system. The vagus nerve plays a crucial role in calming the body after stress and returning it to a state of balance.

This is where yoga comes in. For thousands of years, the practice of yoga has harnessed this ancient wisdom to stimulate the vagus nerve and promote relaxation. Today, our science is finally catching up to what these traditions have known all along: yoga is a powerful ways to activate the vagus nerve and support overall well-being.

What is the Vagus Nerve?

Is the Vagus Nerve Only for Relaxing?

The vagus nerve is best known for its role in activating the parasympathetic nervous system, which helps calm the body through the "rest and digest" response. However, it plays a more complex role than just promoting relaxation. The vagus nerve helps maintain homeostasis—the body’s internal balance—so it can also influence upregulation when needed, allowing you to feel energized and focused.

Here’s how this works:

• Relaxation and Downregulation: Most commonly, the vagus nerve helps the body downregulate after stress by lowering the heart rate, reducing blood pressure, and promoting digestion. This is particularly helpful when you’re feeling overwhelmed or anxious, as it brings the body into a state of calm.
• Energizing and Upregulation: While the vagus nerve primarily aids in relaxation, proper vagal tone can also help with upregulation. By maintaining balance in the body, it enhances your ability to switch between states of relaxation and alertness. When your vagus nerve is toned, it allows you to recover from stress more easily, leading to improved energy and focus.

In some cases, techniques like cold exposure or breath-holding have been shown to briefly engage the sympathetic nervous system (the "fight or flight" response), offering a temporary boost in alertness and energy. However, breath-holding should never be practiced in water, as this can be dangerous. These techniques, when practiced safely, may activate a short-term stress response, followed by the vagus nerve's calming effect to bring the body back to balance.

Although the vagus nerve doesn't directly energize you, stimulating it through yoga, breathwork, and even cold exposure helps improve your overall energy balance. This creates a more flexible system, allowing you to access both relaxation and alertness as needed, based on your body's demands.

What is Vagal Toning?

Toning the vagus nerve means strengthening and enhancing its function, which helps the body manage stress and maintain internal balance more effectively. A toned vagus nerve can better regulate the parasympathetic nervous system, leading to improved relaxation, a lowered heart rate, better digestion, and faster recovery from stress.When we talk about vagal tone, we’re referring to the activity level of the parasympathetic nervous system. Higher vagal tone is linked to improved physical and mental health, including:

• Reduced inflammation: A well-toned vagus nerve helps decrease inflammation, boosting the immune system.
• Better emotional regulation: It supports better management of stress and anxiety.
• Improved heart health: Higher vagal tone is connected to heart rate variability (HRV), which is a key indicator of heart health.
• Enhanced digestion: A well-functioning vagus nerve improves digestion by helping regulate gut function.

The more you engage in practices that stimulate the vagus nerve—like yoga, breathwork, and meditation—the stronger your vagal tone becomes, allowing your body to shift between relaxation and action more efficiently.

The Vagus Nerve and Mental Health

Now, we can’t talk about the vagus nerve without talking about mental heatth, as tehre is a strong connection between them. Stimulating the vagus nerve can help reduce symptoms of anxiety and depression by lowering cortisol levels and bringing balance to the nervous system. Yoga provides a natural and accessible way to activate this nerve, making it a powerful tool for supporting mental well-being.

By regularly practicing yoga, you help tone the vagus nerve, making it more efficient at regulating the body’s response to stress. Over time, this creates greater emotional resilience, allowing you to bounce back from stress more easily.

How to Incorporate Vagus Nerve Yoga Into Your Practice

Incorporating yoga that stimulates the vagus nerve doesn’t require a specific style or set of poses. The good news is that any yoga practice can offer benefits, as long as it encourages mindful movement and breathwork. Whether you're doing a flow class, restorative yoga, or focusing on breathwork, yoga in general is effective for vagal stimulation. At Heart and Bones online yoga, you can hit play on any class that suits your mood or needs, and still experience the calming, stress-relieving effects.

Daily Practices

You don’t need to overcomplicate your routine. Simply spending a few minutes focusing on breathwork or moving through your favourite yoga poses can help calm the nervous system and support vagal tone. Remember, it's the combination of consistency and mindfulness that really counts.

Consistency is Key

As with any aspect of yoga, consistency is crucial. The more regularly you stimulate the vagus nerve, the better your body becomes at managing stress. Small, daily practices add up over time, bringing long-term benefits that help you feel calmer, more balanced, and resilient.
