the vagus nerve and why it matters in yoga?
Have you ever had a “gut feeling” about something and followed it, even though you couldn’t explain why?
That phrase may be more literal than you think.
When we talk about the vagus nerve, we’re talking about one of the body’s main communication pathways, a kind of internal superhighway that connects your brain to many of your most important bodily systems.
The vagus nerve is the longest cranial nerve in the body. It plays a key role in regulating functions such as digestion, heart rate, breathing, immune response, and stress recovery. It connects your brain to your heart, lungs, reproductive organs, and yes…your gut.
This is one of the reasons yoga can feel so powerful. Yoga doesn’t just stretch muscles. It helps regulate your nervous system, support stress recovery, and improve your body’s ability to shift out of survival mode.
Understanding Your Nervous System
Before we dive deeper into the vagus nerve, it helps to understand the nervous system as a whole.
Your nervous system includes your brain, spinal cord, sensory organs, and the network of nerves that send signals throughout your body. One of its most important parts is the autonomic nervous system (ANS), which controls the automatic functions you don’t consciously think about, things like breathing, digestion, blood pressure, and heart rate.
The autonomic nervous system has two main branches:
The sympathetic nervous system (SNS)
The parasympathetic nervous system (PNS)
The Sympathetic Nervous System: Fight, Flight, freeze
The sympathetic nervous system is your body’s stress response system.
When your brain perceives danger or pressure, the SNS is boosted to help you survive. Your heart rate increases, your breathing quickens, and blood flow is redirected away from non-essential systems like digestion and reproduction.
This response is incredibly useful in short bursts. The problem is that modern life often keeps us stuck here. Constant notifications, long working hours, financial stress, emotional overload, doomscrolling, and always being “on.”
Many of us are living with a nervous system that rarely gets the signal that it’s safe to slow down. Over time, chronic stress can contribute to exhaustion, sleep disruption, anxiety, burnout, digestive issues, and increased inflammation in the body.
Imagine traffic lights permanently stuck on green. Eventually, there would be chaos.
The Parasympathetic Nervous System: Rest and Digest
The parasympathetic nervous system does the opposite.
This is your body’s “rest and digest” response, the state associated with restoration, healing, digestion, relaxation, and recovery.
When the parasympathetic nervous system is boosted:
Your heart rate slows
Your breathing deepens
Digestion improves
Your body begins repairing and restoring itself
And this is where the vagus nerve becomes incredibly important.
What Is the Vagus Nerve?
The vagus nerve is the main nerve of the parasympathetic nervous system.
It begins at the base of the skull and “wanders” throughout the body, which is actually where its name comes from. The word vagus is derived from the Latin word for “wandering.”
The vagus nerve constantly gathers information from your organs and sends messages between your body and brain. It helps regulate how you respond to stress and how easily you can return to a calm, balanced state afterward.
This ability is often referred to as vagal tone.
What Is Vagal Tone?
Vagal tone refers to how well your vagus nerve functions and how effectively your body can move between states of stress and relaxation.
Higher vagal tone is associated with:
Better stress resilience
Improved digestion
Emotional regulation
Better sleep
Improved heart health
Greater ability to recover after stress
In simple terms: the stronger your vagal tone, the easier it becomes for your body to return to a state of calm after stress.
How Yoga Supports the Vagus Nerve
This is where yoga becomes more than movement.
Research suggests that yoga may help regulate the nervous system and improve vagal tone through practices that activate the parasympathetic nervous system.
Yoga supports the vagus nerve through practices such as:
Breathwork (Pranayama)
Meditation
Chanting and humming
Restorative yoga
Yoga Nidra
Mindful movement
These practices help signal safety to the body.
Over time, repeated activation of the parasympathetic nervous system can help create new neural pathways and healthier stress responses. In other words, yoga helps teach your body how to rest again.
Why Some People Struggle to Relax in Yoga
If you’ve ever felt uncomfortable during Savasana or struggled to slow down in a yoga class, you’re not alone.
I see this all the time. For many people, stillness can feel unfamiliar, even unsafe. When we stop distracting ourselves, uncomfortable thoughts, emotions, or tension often rise to the surface. But the nervous system learns through repetition.
Every time you consciously pause, breathe deeply, or rest in stillness, you send a message to your body that it is safe to soften. Over time, that response becomes more accessible.
Burnout, Stress, and the Need for Rest
Over the past few years, conversations around burnout and nervous system regulation have become increasingly common, and for good reason. Many people are exhausted.
We’ve normalised overworking, constant productivity, and being emotionally available 24/7. Even rest can feel something we need to “earn.” But your nervous system was never designed to operate under constant pressure. Rest isn’t laziness. It’s a biological need.
When we don’t allow ourselves proper recovery, stress starts showing up everywhere, in our sleep, digestion, focus, mood, relationships, and physical health. Sometimes the most productive thing you can do is pause.
Simple Ways to Stimulate the Vagus Nerve
You don’t need an hour-long yoga practice to support your nervous system.
Small, consistent practices can make a huge difference.
1. Breathwork (Pranayama)
Your breath is one of the quickest ways to influence your nervous system.
Try this:
Take a slow inhale through your nose
Exhale slowly and fully
Repeat for 3–5 breaths
Simple, but effective.
This is one of the reasons yoga classes often begin with conscious breathing. It helps shift your body into a more grounded state.
2. Humming, Chanting, and Singing
The vagus nerve is connected to the vocal cords and throat. Humming, chanting, singing, or even gentle vocal toning can help stimulate the vagus nerve and create a calming effect in the body.
Next time you’re stressed, try softly humming on your exhale for a few breaths and notice how you feel afterward.
3. Meditation and Stillness
Meditation doesn’t have to mean sitting perfectly still on a cushion.
Meditation can be:
Walking slowly in nature
Listening to calming music
Lying on the floor and focusing on your breath
Practising Yoga Nidra
Simply noticing the sensations in your body
Meditation is less about “emptying your mind” and more about learning how to return your attention to the present moment.
Yoga Nidra and Deep Rest
One of the most effective practices for nervous system regulation is Yoga Nidra.
Yoga Nidra, sometimes called “yogic sleep,” is a guided meditation practice designed to bring the body into deep rest while maintaining awareness.
Many people find Yoga Nidra helpful for:
Anxiety
Stress management
Sleep difficulties
Burnout recovery
Nervous system regulation
It’s one of the most accessible ways to experience deep rest, especially for people who struggle to switch off.
Final Thoughts: Why the Vagus Nerve Matters in Yoga
The vagus nerve plays a huge role in your overall wellbeing.
When you practise yoga, breathwork, meditation, restorative yoga, or Yoga Nidra, you’re not just “relaxing.” You’re actively supporting your nervous system and helping your body build resilience to stress. Yoga teaches self-awareness, regulation, and recovery. In a world that constantly encourages speed, stimulation, and overworking, learning how to slow down may be one of the most important skills we can cultivate.
If you struggle to rest, you’re not failing at relaxation. Your nervous system may simply need support, safety, and practice. That practice can begin with something as simple as one deep breath.
