There’s something ancient, primal, and deeply human about singing. Whether it’s belting out your favorite tune in the shower, chanting in a sacred circle, humming while cooking, or harmonizing with others under the stars—singing does something to us.
And neuroscience is catching up to what your soul already knows:
Singing is therapeutic. It’s medicine. It’s vagus nerve therapy in action.
Let’s dive into why. 💫
🎵 What is the Vagus Nerve?
The vagus nerve is the body’s longest cranial nerve. It connects your brainstem to your heart, lungs, digestive system, and more. It’s a key part of your parasympathetic nervous system, which governs rest, digestion, connection, and healing.
When trauma has dysregulated the nervous system—keeping us in chronic fight, flight, or freeze—the vagus nerve can become hypo- or hyperactive. That’s where vagal toning comes in.
And guess what? Singing is one of the most natural ways to tone your vagus nerve.
🎶 Why Singing Works for Nervous System Regulation
Singing stimulates the vagus nerve in several beautiful ways:
🌬️ Breath Control – Singing slows and deepens your breath, shifting you out of shallow, anxious breathing and into a more regulated, relaxed state. This stimulates the parasympathetic response.
🗣️ Vocal Cord Vibration – The act of using your voice—especially sustained vowel sounds, humming, or chanting—activates the vagus nerve through vibrations in your larynx and pharynx.
❤️ Heart Rate Variability (HRV) – Singing improves HRV, which is a key marker of vagal tone. A higher HRV is associated with greater emotional regulation, resilience, and overall well-being.
👂 Polyvagal Theory in Action – Dr. Stephen Porges’ groundbreaking work shows that the vagus nerve is tied to our social engagement system—facial expression, tone of voice, eye contact. Singing with others co-regulates our nervous systems and builds safe connection—something trauma survivors often deeply long for.
🌈 Singing: A Simple Daily Practice for Healing
Whether you’re healing from trauma, living with anxiety, or simply seeking deeper connection to your body and emotions, singing can be a profound anchor.
Try this:
- Morning Humming: Start your day with 5 minutes of gentle humming while placing a hand on your chest or belly.
- Vocal Toning: Chant “Om,” “Ah,” or “Ee”—slow, elongated sounds—for a few minutes. Notice the vibrations.
- Sing Freely: In the car, shower, or kitchen—anywhere! Let your voice rise without judgment.
- Sing in Community: Join a choir, sing with friends, or simply harmonize with others. Co-regulation is powerful medicine.
💚 Your Voice is a Path to Healing
So, if you’ve ever felt tears rise while singing…
If your chest opens up mid-song…
If a melody stirs something you thought you had lost…
That’s not just music. That’s your nervous system remembering safety.
Let yourself sing. Loud, soft, off-key, in harmony.
Let your voice be a signal to your body that you are alive, connected, and free to heal.
Your vagus nerve thanks you.
Your nervous system thanks you.
And your inner child? She’s probably singing too. 💖
