5 Signs Your Nervous System Is Dysregulated (And What To Do About It)
I was in a meeting. An ordinary one — nothing on fire, nobody upset with me. And yet something in my chest was braced. My jaw was tight. I kept waiting for something bad to happen.
Nothing happened. The meeting ended. I sat at my desk and couldn’t understand why my body was still in it — still coiled, still scanning. I’d eaten. I’d slept. By every external measure, everything was fine.
That’s the thing about a nervous system that won’t settle. It doesn’t care about your calendar. It doesn’t respond to your reasoning. You can know, intellectually, that you’re safe — and your body will carry on as if it received no such memo.
I’ve spent a long time learning to read my body’s signals. Not to fix them. Just to understand them — to recognise what they’re trying to tell me before they have to shout. Here are five I kept missing for years.
Sign one
You’re waiting for something to go wrong
Not in a visible, obvious way. You’re not catastrophising out loud. You’re just… braced. There’s a low-level hum of anticipation beneath everything you do. You finish one thing and immediately start scanning for the next problem. You reach the end of a good day and feel vaguely suspicious of it.
I used to think this was just my personality. That some people were simply wired for vigilance. And maybe there’s some truth in that — but I’ve also learned that this particular flavour of always-waiting is what a nervous system that has been on alert for a long time looks like. It’s not pessimism. It’s an old protection that hasn’t gotten the message that things are different now.
“I used to think this was just my personality. Now I think it was my body keeping watch — because once, it had to.”
Sign two
Small things land too hard
The tone of a text message. A plan that changed at the last minute. Someone not saying hello when they usually do. Things that, on a different day, would wash over you — but today, they drop in like stones.
The reaction feels disproportionate, and that’s the part that’s the most destabilising. You know it’s a small thing. You can see that it’s a small thing. And still your body responded as though it wasn’t. And then you add shame on top of the original feeling, which is its own particular kind of exhausting.
What I’ve come to understand — slowly, imperfectly — is that the reaction isn’t about the thing itself. The reaction is the size of everything that came before it. The text message is just the last straw. The nervous system was already full.
Sign three
You’re tired in a way that sleep doesn’t fix
This one took me the longest to recognise because I kept looking for a physical explanation. Iron levels. Thyroid. Sleep quality. Hours. And while those things matter, what I was experiencing wasn’t the tired that comes from not enough rest. It was the tired that comes from carrying something at a cellular level — from a body that has been working hard to hold you together.
A regulated nervous system can restore itself through rest. A dysregulated one keeps working even when you’re still. Even when you’re asleep. That’s why you can wake up after eight hours and feel like you didn’t sleep at all. Your body was busy. It just wasn’t busy with anything you’d chosen.
“It wasn’t the tired that comes from not enough sleep. It was the tired that comes from a body that hasn’t known how to stop.”
Sign four
You find it hard to be fully present anywhere
You’re at dinner with someone you love, and a part of you is somewhere else. You’re in your body but not quite in your life. There’s a pane of glass between you and the moment — you can see everything clearly, but you can’t quite get to it.
Sometimes people call this dissociation. Sometimes it’s just called feeling flat, or checked out, or like you’re going through the motions. Whatever word fits, the feeling underneath is the same: your system is managing by keeping you at a slight remove from things, because being fully in them feels like too much.
I noticed this most in good moments — moments I wanted to be present for. It wasn’t numbness, exactly. It was more like my capacity for arrival had gotten very small. I could be there. I just couldn’t quite land.
Sign five
Your body is braced even when nothing is happening
Shoulders up near your ears. Breath shallow in your chest. Stomach knotted on an ordinary Tuesday with nowhere to be. You’re not doing anything stressful. You’re just existing — and your body is in a low-level state of readiness that nobody asked for.
This one I now think of as the baseline that I confused for normal for a very long time. I thought everyone felt this way. The quiet hum of physical tension as a constant companion. It wasn’t until I experienced what it felt like without it — briefly, unexpectedly, after a particularly slow weekend — that I understood that it wasn’t inevitable. It was a habit. A very understandable one. But a habit.
None of this is about fixing anything quickly. I’m not going to tell you that one breathing practice will resolve it, because that hasn’t been my experience — and I don’t think it will be yours.
What I can tell you is that recognising these signs for what they are — not character flaws, not proof that something is wrong with you, but signals from a system that’s been working overtime — has been the beginning of something. Not an arrival. Just a different kind of attention.
Your body has been trying to tell you something. It’s been trying for a while. It doesn’t need you to fix it today. It needs you to start listening.
“Your body isn’t against you. It’s been doing its best with what it was given — in the only language it knows.”
If any of this landed for you — if you read one of those signs and felt that small, strange relief of being seen — then you’re probably someone whose body has been carrying more than it’s been allowed to put down.
There’s no rush. Come back when you’re ready.
