Discover how humming boosts nitric oxide, calms the vagus nerve and supports expression.
Have you ever swallowed your words in a meeting, bitten your tongue to keep the peace or wished you’d spoken your truth but stayed silent instead? We’ve all been there. And it leaves more than frustration, it creates tension, especially in the throat and chest.
That’s because the Throat is about much more than just speaking. It’s about courage, expression and authenticity. When it’s blocked, we feel silenced, small or unsure. When it’s balanced, we feel clear, confident and free to express who we really are.
And the key to unlocking it? Your breath.
Breath and voice are inseparable. You literally ride your breath every time you speak. No breath = no voice.
Singers know this better than anyone. To sustain a note, you need control of the exhale. To project with resonance, you need the lungs, diaphragm and voice box to work together in harmony. Breath sets the rhythm and voice gives it expression.
This is why ancient traditions across the world have always paired breath and sound... from chanting mantras in yoga to reciting prayers like the Ave Maria. Fascinatingly, research has found that both practices naturally slow the breath to around 6 breaths per minute, the same “resonance frequency” modern science identifies as the most beneficial for heart and nervous system coherence (read more in this post). Long before physiology labs existed, spiritual rituals were guiding us into balance.
Here’s where it gets even more exciting. Research shows that humming can increase nitric oxide production in the nasal passages by up to 15 times compared to quiet breathing.
Why does that matter? Nitric oxide is a tiny but mighty molecule that:
So when you hum, you’re not only soothing yourself, you’re also giving your biology a natural boost. But there is more!
Enter the vagus nerve, the main “rest-and-digest” pathway of your nervous system. Vibrations from humming, chanting or even gargling stimulate this nerve, sending a signal of safety to the brain. That’s why a simple hum can shift anxiety so quickly: your throat isn’t just making sound, it’s sending calm through your whole body.
When the Throat is out of balance, it often looks like:
When the Throat is balanced, you feel:
The throat is where breath becomes voice. When you reclaim that space, you reclaim your power to be heard.
Finding your voice doesn’t require making a speech or singing on a stage. It starts with simple practices: a hum, a breath, a ritual that reminds you: “My voice matters.”
To celebrate the Throat archetype, I love this cooling recipe. It’s packed with blue and purple foods that nourish the body and symbolically honour the energy of expression.

Throat Pro Tip
Humming through the nose has been shown to increase nitric oxide production by up to 15x. Try humming for one minute and not only will your sinuses thank you, but your nervous system will too.
