Congrats, Your Nervous System Thinks You're Being Cornered By A Bear (The Fight Response)

You know that feeling when somebody cuts you off on the highway — no turn signal, nothing — and suddenly your heart's pounding, blood's rushing in your ears, and you're yelling at a car that can't even hear you?

Or maybe it's smaller than that. Your kid still hasn't done the dishes for the umpteenth time. There are socks on the floor, right next to the laundry basket. Someone's walking painfully slowly in front of you in the grocery store, and you're standing there seething, muttering "excuse me" through gritted teeth.

Sound familiar? Well, honey — that's your fight response. And your nervous system just interpreted all of that as "oh fuck, I'm being cornered by a bear." Then it made an executive decision: actually, I think I'm gonna fight this motherfucker.

This post kicks off a brand new series I'm doing all about the nervous system — the 4 States, the Window of Tolerance, the Polyvagal Ladder, and how it all fits together, plus real tools you can actually use. We're starting here, with Fight.

It's Not Always Loud

We all know the obvious version of fight — yelling, explosive anger, physical aggression. It's in the name. But fight response shows up in a lot of quieter, sneakier ways too, and chances are you've been doing at least one of these without ever clocking it as "fight":

• Passive-aggression — loudly washing dishes, slamming cabinets, instead of just asking for help

• Micromanaging — hovering over your kid folding laundry, correcting them because it's "not right," even though it's none of your business

• Defensiveness — someone gives you feedback and you're already loading up comebacks before they've finished the sentence

• Stubbornness — staying combative just to stay combative, even when you know you've got no leg to stand on

• The silent treatment — yeah, I see you. You may not be saying anything out loud, but what's happening in your boy and in your head while you're ignoring them? Be honest.

Sometimes there's no one around to aim it at, so it turns inward instead:

• Hyper-criticism — picking apart everything and everyone, nothing's ever quite right

• Intellectualizing — winning the argument with logic so you don't have to feel whatever's actually underneath it

Or it just shows up in your body — a clenched jaw, a hard stare, the kind of look that says "I could kill you" without a single word

I'll be honest — I've lived a lot of these. I grew up with an angry father, and I've known for a long time that anger has been my thing to work through too. Working with my own nervous system is what's given me the ability to actually pause instead of just reacting — but I'm not gonna pretend I've got it all figured out. When I'm stressed and skipping self-care, my triggers still come faster and hotter than I'd like. A few days before I recorded the episode this post is based on, I snapped at my husband over video chat because he asked me to repeat myself. That's it. That's all it took.

And that's actually worth naming: usually the thing that sets you off isn't really the thing you're mad at. It's just the extra bit of stimulation on a system that was already maxed out, and suddenly your body's screaming danger, danger.

What's Actually Happening In Your Brain

Here's the mechanism behind that cornered-by-a-bear feeling. Your amygdala — your brain's alarm system — senses a threat before you've even consciously clocked what set it off. It hijacks the show, and your prefrontal cortex (the rational, reasonable, impulse-controlling version of you) gets dialed way down. Not off, but definitely shoved into the back seat.

What takes over instead is your lower brain — your limbic system and brainstem, also known as your reptilian brain. It's the oldest part of your brain, evolutionarily speaking, wired purely for survival, not making judgment calls. It doesn't know the difference between an actual bear and a dish in the sink.

At the same time, your sympathetic nervous system floods your body with adrenaline and cortisol. Blood moves from your gut into your limbs, your heart rate spikes, your breath goes short and fast, your muscles tense — your whole body prepping for a physical fight. And all of this happens in milliseconds, before your thinking brain even gets a vote.

The problem is that everything your body just mobilized — the adrenaline, the tension, the readiness — was built for something way bigger than what actually triggered it. Your body geared up to fight a bear over a dirty dish. But there's no bear. It's your kid. Your partner. So you end up tearing into someone you love over nothing, and left holding all the guilt afterward.

And if that energy doesn't get released outward at all — if it just stays inside — it doesn't disappear. It gets stuck, with nowhere to exit, and that's what causes problems down the line.

You're Not Broken

This is the part I really want you to sit with: this response isn't a defect. It's not evidence that something's wrong with you. Your body is being incredibly wise here — it's doing exactly the job it was designed to do, it just misfired on what counted as a threat. This system kept our ancestors alive against actual predators. It's ancient, and it's really good at its one job: keeping you alive right now, at all costs, no time to fact-check first.

The problem isn't that you have this system. The problem is the system can't tell a bear from a dish in the sink — all it knows is that energy needs to mobilize, right now.

What you're actually carrying in these moments is charge — built-up energy that mobilized for a threat that never physically showed up. It's not "you're an angry person." It's not "something's wrong with you." It's unspent energy with nowhere to go yet. You are not an asshole. You are not too much. You are not broken. You're a person whose body took its job of protecting you extremely seriously — maybe a little too seriously for a slow walker in the grocery store, but seriously nonetheless.

And I know how fast the shame spiral kicks in after. That voice that shows up right after you snap, telling you what a failure you are, that you're going to drive everyone away, that you're incapable of getting it together — I know that voice. It sucks you in like a whirlpool. But here's the thing: that shame doesn't discharge any of the energy. It just adds another layer of activation on top of the first wave, and spirals you further down.

So if the energy is the actual problem — not you, not your character — then the fix isn't "be a better person." It's giving the energy somewhere to go.

Give It Somewhere To Go

Your body prepared for a fight that never physically happened. When it doesn't get to do the thing it geared up for, that energy gets stored instead of released. So we have to move it out on purpose, since it didn't get the chance to move itself out the way it was supposed to.

One simple way to do this: press your palms together, hard, in front of your chest, and hold it. This is called isometric resistance — muscle engagement against resistance, with no actual movement — and that engagement itself is what discharges the energy. Push as hard as you can, then release and shake your hands out.

You can apply the same principle almost anywhere:

• Push against a wall with your whole body

• Grip the steering wheel of your car and press into it

• Press your palms hard into your thighs

• Press your feet hard into the floor

• Shrug your shoulders up to your ears, hold tight, then drop

• Clench your fists, then release

If there are words about to come out of your mouth that you know will hurt someone, go scream into a pillow instead. It's genuinely cathartic.

And if you've got the space and privacy for it, a full-body release works even better — shake your whole body out, do some heel stomps, punch the air. It feels ridiculous and it feels really good.

None of this is about performing calm when you're not. Pretending to be calm doesn't actually make you calmer. These practices are about actually letting the charge move through and out — so it doesn't end up in your jaw, in your kid's face, or in two days of silent treatment you didn't mean to give.

Where This Goes From Here

So next time you feel that heat rising — you'll know exactly what's happening. Your body's not broken. It's just ready to fight a bear that isn't there. And now, you've got somewhere to put that energy besides your kid's face.

If this is the first time you've actually had a real tool for this — welcome. There's more where that came from. If you're the type who's ready to get to the actual root of this instead of just managing it moment to moment, that's the work I do inside The Relief Container, my 12-week 1:1 coaching program for people who are done white-knuckling their nervous system and want it actually regulated.

But fight isn't the only way your body handles a threat that isn't real. Sometimes, instead of squaring up, your body decides the smartest move is to get the hell out — and that one's just as sneaky. That's next time.
