"Nervous system regulation." You've heard it everywhere lately. But before your eyes glaze over — what if the secret to actually feeling calmer, more grounded, and more like yourself was already wired into your body?
We spend a lot of time trying to think our way out of stress. Reframe the thought! Change your mindset! But here's something brilliant that your body has been trying to tell you: most of the conversation isn't happening in your head at all. It's happening from the neck down.
Enter the vagus nerve. Possibly the most fascinating thing about you that you've never given a second thought to.
So, what actually is it?
The vagus nerve is the longest cranial nerve in your body. It starts at the base of your brain, winds down through your neck, passes through your chest, and travels all the way into your gut — connecting your brain to your heart, lungs, and digestive system along the way. The name literally comes from the Latin word for wandering, which feels very appropriate.
Think of it as a two-way motorway between your brain and your body. Information zips up and down constantly. But here's the bit that might surprise you: roughly 80% of the signals travel upward — from body to brain, not the other way around. Your body is doing most of the talking.
It's not "mind over matter." It's actually "body before brain." Your nervous system is constantly scanning for signals from your physical self — and making decisions about your safety, mood, and stress levels based on what it finds.
Why should you care?
When your vagus nerve is functioning well, your system can bounce back from stress more easily. You go from wound up to settled without it taking all day. When it's not functioning so well, you might notice things like:
→ Feeling wired but exhausted — like you can't quite switch off → Digestive issues that seem to flare up when you're stressed → Anxiety that seems to come from nowhere → Poor sleep even when you're completely knackered → A vague sense of being "on edge" that you can't quite explain
And it's not just about how you feel in the moment. Your vagus nerve is also involved in immune function, inflammation levels, digestion, heart rate, and how well you recover from illness or exertion. It really is a big deal.
The body-brain loop (and how to use it)
Here's where it gets exciting. Because so much of the information flows upward, you can actually influence how your brain feels by changing what your body is doing. You don't have to fix your thoughts — you can start with your physical state.
When your body is tense — jaw clenched, shoulders around your ears, breathing shallow — your nervous system reads that as "something is wrong, stay alert." When your body feels steady, open, and supported, it signals the opposite: you're safe, you can relax.
This is one of the reasons that slow, intentional movement like Pilates is so powerful for your nervous system — not just your body. It teaches a new pattern: effort, then breath, then release. And your brain takes notes. Over time, your body learns that it can be under load without going into stress. You build strength, yes — but you also build trust.
Posture plays into this too. A slumped, collapsed posture restricts your breath and compresses your chest — physically signalling to your nervous system that something is wrong. Opening the chest, lengthening the spine, breathing fully — these aren't just aesthetic corrections. They are nervous system corrections.
Small things that genuinely help
You don't need a complete lifestyle overhaul. Your vagus nerve responds to consistent, gentle inputs — the everyday stuff matters more than you'd think.
Slow your breath — A long exhale activates the parasympathetic system. Even three slow breaths can shift something.
Move with intention — Rhythmic, controlled movement sends a "you're safe" signal to your nervous system. It's nourishment, not just fitness.
Eat with some rhythm — Your gut is in constant conversation with your brain via the vagus nerve. Regular, nourishing meals create stability. Chaotic eating patterns can do the opposite.
Protect your sleep — Deep sleep sends one of the clearest signals of all: we're safe. When your days have rhythm, your nights tend to follow.
Move with other people — There's something real that happens when people move in sync. Shared rhythm and shared breath actually regulate your nervous system without you even trying.
Take tiny pauses — Even 30 seconds interrupts the cycle of rushing and gripping. It reminds your system there is time.
How this connects to everything we do at Claire's Amazeballs
When I understood what the vagus nerve actually does, it reframed everything about why I teach the way I do — and why I make the energy balls the way I make them.
In every Pilates and posture class, we move slowly and deliberately. We breathe with intention. We work on posture that opens rather than collapses. None of that is accidental. It's exactly the kind of movement that sends your nervous system a "you're safe" signal — and over time, your body starts to carry that feeling into the rest of your day.
And the balls? Your gut and your brain are in constant conversation via the vagus nerve. What you eat is literally information your nervous system acts on. Real ingredients, balanced nourishment, nothing your body has to fight through — that's not just good nutrition. That's supporting the whole system.
Move well. Eat well. Feel well. It genuinely is that connected.
The bottom line
Instead of trying to outthink your stress, try supporting your body first. Create a bit of rhythm. A bit of steadiness. Small, consistent moments of calm.
Your body is always sending signals — through how you move, how you breathe, how you eat, how you rest. And your brain is always listening. Give it good information to work with, and over time, your whole system starts to learn: this is what safety feels like.
And honestly? That's pretty amazeballs.
Try this now: sit tall, drop your shoulders, and take five slow breaths where your exhale is longer than your inhale. That's your vagus nerve you're talking to. And it's listening.
