3 Ways to Calm Your Nervous System and Use Your Body’s Reset Button

I don’t remember the robbery in Bogotá, but I’ll never forget the weeks that followed, a slow drowning in red tape, blocked accounts, and a body that stayed frozen in a crisis it didn’t have the memory to process.

I’d wake up at 4 AM with my jaw clenched. A door slamming would make my heart spike. I couldn’t walk past someone on the street without my shoulders tensing. My mind knew the danger was over. My body didn’t believe it.

I teach people how to work with their nervous systems. But knowing the theory doesn’t make you immune. So I went back to basics by focusing on the vagus nerve.

What the Vagus Nerve Actually Does

The vagus nerve is the longest nerve in your body. It runs from your brainstem down through your chest and into your abdomen, connecting your brain to your heart, lungs, and digestive system.

It’s the main highway between your brain and your body. When it’s functioning well, you recover from stress quickly. You sleep better. You feel grounded. When it’s not, your body stays stuck in high alert, even when there’s nothing to be alert about.

This nerve controls your parasympathetic nervous system (your “rest and digest” mode). The problem? Modern life, chronic stress, and trauma can all dysregulate it. Your body forgets how to turn off the alarm.

You can stimulate it directly. And it doesn’t take long.

Three Ways to Activate Your Vagus Nerve (Right Now)

These are quick, physical interventions you can do anywhere. No 30-minute meditation required.

1. Cold Water on the Face

I splash cold water on my face or hold a cold pack against my forehead for 30 seconds. This triggers the “diving reflex,” an evolutionary response that slows your heart rate and signals to your vagus nerve that you’re safe. Your body interprets the cold as a signal to conserve energy, which shifts you out of fight-or-flight mode. It is an ideal circuit breaker to use when you feel panic rising or when your thoughts start spiraling.

2. The power of the extended exhale

I breathe in for 4 counts, then out for 6 or 8, and continue this for 3 to 5 minutes. Your vagus nerve is activated on the exhale, so making your exhale longer than your inhale tells your nervous system that you’re safe enough to slow down. This isn’t theory. It is a measurable process where your heart rate variability, a marker of nervous system flexibility, increases with every long breath. This practice is especially effective before bed, after a stressful conversation, or whenever you notice your breath is shallow and high in your chest.

3. Humming as a biological signal

I hum a simple “OM,” sing in the shower, or just hum my favorite song. Because the vagus nerve passes through your vocal cords, creating vibrations in your throat directly stimulates the nerve. This is why chanting is a core part of yoga and meditative traditions. It is not mystical but anatomical. This is a quick way to ground yourself when you feel disconnected from your body or need to find focus before a difficult situation.

Why This Matters (For Anyone in Transition)

When you’re living through constant change, whether that’s moving between countries, switching careers, ending a relationship, or recovering from trauma, your nervous system is perpetually recalibrating. You’re asking your body to adapt to new stimuli, often without giving it time to process what just happened.

For me, that change comes from living location-independently. But the principle is the same whether you’re a parent juggling work and home, someone recovering from a breakup, or anyone whose life feels like it’s moving faster than your body can handle.

The hardest part isn’t the external logistics. It’s the internal instability. If your nervous system is dysregulated, you’re not fully present anywhere. You’re just surviving in whichever environment you find yourself.

Your nervous system isn’t broken. It’s just stuck in a pattern.

After Bogotá, I had to relearn how to feel safe in my own body. These practices were my entry point. They didn’t fix everything overnight, but they gave me a way to intervene when the panic hit.

If you’ve been through something that left your nervous system on high alert, or if you’re moving through any kind of major life transition, these tools won’t solve everything. But they’ll give you a reset button when you need it most.

The Deeper Work

These are entry-level practices. They work, but they’re not the full picture.

I wrote more about how trauma stays in the body after the threat is gone in my article Erased in Bogotá (And How My Bank Erased Me Twice). That piece goes deeper into the aftermath of acute stress and the tools I used to reclaim my sense of safety.

Want to go deeper? I use a 15-minute somatic practice that combines breathwork, body scanning, and nervous system regulation when I need a full reset. You can read about it here: The 15-Minute Practice That Keeps Me Sane.

Try One Today

You don’t need to do all three. Pick the one that feels most accessible right now and try it once. Notice what shifts and what doesn’t. Which one are you trying first? Let me know in the comments.
