The Dysfunctional Stress Response: Why Your Body Can't Seem to Switch Off

Jan 7 / Flourishing With Fibromyalgia

It's 11:47pm and you are lying perfectly still in a dark room, doing everything "right." No screens, no caffeine since noon, a warm bath an hour ago. And yet your heart is thudding just a little too fast, your muscles won't quite unclench, and your mind is running through tomorrow's to-do list like it's being graded. You are exhausted. You are also, somehow, wide awake.

If that sounds familiar, I want you to know something before we go any further: this is not you failing at relaxation. This is your body's stress response, and if you have fibromyalgia, there's a good chance yours has forgotten how to switch off.

Understanding the dysfunctional stress response is, in my experience working with hundreds of people living with fibromyalgia, the single biggest turning point in how they come to understand what's happening in their bodies. It's not the whole picture, but it is the foundation everything else gets built on. So let's start here.

You're Not Imagining This (and You're Not Broken)

I want to name something a lot of you are carrying, quietly. You've likely had bloodwork come back "normal." Maybe more than once. You've been told your labs look fine, your imaging looks fine, and yet you feel anything but fine. Some of you have been handed a look that says "maybe this is in your head" without anyone actually saying the words.

I've heard some version of this story more times than I can count from the people I work with. It's disorienting to feel this unwell in a body that keeps testing "normal." It can make you start to wonder if you're the problem, if you're not trying hard enough, or if you've simply lost the ability to relax like other people seem to.

You haven't. What's actually happening is that your body's stress response, the very same system every human has, is stuck in a phase it was never designed to stay in for long. And once you understand that system, a lot of your symptoms stop feeling random and start feeling explainable.

What the Stress Response Is Actually Doing

Every human body has a built in alarm system. When you're exposed to a stressor (physical, mental, or emotional), your body responds the same way every time. Your brain sends a message down what's called the HPA axis (hypothalamic-pituitary-adrenal axis, in case you ever want to impress someone at a dinner party) straight to your adrenal glands, and they release hormones like adrenaline and cortisol to help you survive whatever is in front of you.

In plain English, this means your heart beats faster, your breathing quickens, your muscles tense up and get ready to move, and blood gets rerouted away from "non-essential" functions like digestion, toward your muscles and brain instead. This is often called fight or flight, though researchers now also talk about freeze and fawn as part of the same family of responses. Maybe you don't fight or flee, maybe you freeze up, or maybe you find yourself smoothing things over to keep the peace even when it costs you. All of these are your nervous system doing exactly what it was built to do.

Here's the part that matters most for our purposes: this response has three phases. There's the alarm phase, which is short and sharp, the initial jolt. If the stressor sticks around, you move into the resistance phase, where cortisol stays elevated and your body keeps mobilizing resources to cope. And if that stressor never really goes away, you eventually land in the exhaustion phase, sometimes called burnout, where your body simply can't sustain the effort anymore.

In a healthy, well regulated system, once the stressor passes, the alarm turns off. Your body shifts back into what's called rest and digest mode, repairs the damage, rebalances your hormones, and gets on with things. That's how it's supposed to work.

That switch is what seems to malfunction in fibromyalgia.

Why Your Body Can't Find the Off Switch

Here's the piece that changed everything for me: to your body, a stressor is a stressor. It doesn't distinguish between an argument with your spouse, a stack of unpaid bills, a poor night's sleep, inflammation from something you ate, or a genuinely dangerous situation. Physical, mental, and emotional stressors all get funneled into the exact same physiological response.

Which means if you're dealing with chronic pain (a physical stressor), disrupted sleep (another physical stressor), the emotional weight of feeling unwell and misunderstood, financial pressure from missed work, and the everyday mental load of parenting or a demanding job, your body isn't experiencing "a bit of stress here and there." It's fielding a nearly constant barrage of stressors from every direction, and it never quite gets the all clear signal to stand down.

Research into fibromyalgia has found a number of physical changes that line up with a stress response that's stuck in overdrive, including changes in muscle tissue, low level muscle tension that never fully releases, and disrupted cortisol patterns. We don't have every answer yet (I'll always be honest with you about that), but a dysfunctional stress response is looking more and more like a genuine root contributor to fibromyalgia, not just a side effect of it.

This is why "just relax" has probably never worked for you. Your body isn't choosing to stay activated out of stubbornness or a bad attitude. It's stuck in a genuine physiological state, one that took a long time to develop and will take some patience to shift.

This is exactly the kind of thing I dig into more deeply inside the Flourishing With Fibromyalgia Academy, where we work through, step by step, how to actually calm this system down.

So What Do You Actually Do With This Information?

I'm not going to hand you a ten step plan and pretend that's going to undo years of a dysregulated stress response overnight. That wouldn't be honest, and it wouldn't be fair to you. What I want to offer instead is a shift in how you think about your symptoms, plus one small, doable starting point.

The shift is this: instead of asking "how do I manage my pain," start asking "what is keeping my body's stress response switched on, and how can I help it find the off switch." That reframe alone tends to open up a lot more options than chasing symptoms one by one.

As for a starting point, here's my rule of one. Don't try to overhaul your entire life this week. Just pick one thing.

Notice how you personally experience stress. For the next few days, simply pay attention. Does your jaw clench? Do your shoulders creep up toward your ears? Do you feel wired and unable to sit still, or do you go quiet and shut down instead? There's no right answer here, everyone's stress response shows up a little differently, but you can't work with a system you don't yet recognize in yourself.

Choose one calming practice and do it daily. This doesn't need to be complicated or take an hour. A few minutes of slow, deep breathing, a short guided meditation, or even sitting quietly with a cup of tea before the day gets moving all count. The goal isn't to eliminate stress from your life (good luck to any of us trying that), it's to give your nervous system regular, repeated practice at shifting into a calmer state. The more often you do this, the better your body gets at finding its way back down when things get activated.

That's genuinely it for now. One thing to notice, one small practice to build in. You'll get more from that consistency over the next few weeks than you would from any dramatic overhaul you abandon by Thursday.

And please, if you're working through significant symptoms or considering any new treatment approach, bring these questions to your doctor. I can help you understand what may be going on and what's worked for others, but your own healthcare provider knows your full picture and should always be part of your decisions.

You're Not Starting From Broken

If there's one thing I want you to walk away with today, it's this: your symptoms make sense. Your body isn't malfunctioning randomly, it's responding, in a very predictable and explainable way, to a stress response that's been switched on for far too long. That's not a life sentence. It's a starting point.

Over the next couple of posts, we're going to dig further into how this dysfunctional stress response actually drives day to day fibromyalgia flares, and how you can start working with your nervous system instead of feeling at war with it.

If you want the fuller roadmap, the one that takes you from "okay, now I understand what's happening" to a clear, step-by-step path for calming your stress response, protecting your energy, and understanding what may be keeping your body activated, you'll find it inside the Flourishing With Fibromyalgia Academy. It's the next step for a lot of people living with fibromyalgia who are ready to stop guessing and start following a structured approach.
