In short: Nervous system dysregulation means the autonomic system is stuck in chronic activation or shutdown rather than cycling naturally, and in driven women it’s often mistaken for stress or personality because high performance can mask the underlying state.

The Morning You Didn’t Notice

Dalia’s alarm went off at 5:15 AM, the same time it goes off every morning. She lay there for seven seconds. She knows it was seven seconds because she counted, the way she counts everything, the way counting is the invisible scaffolding that holds her day together. And then she reached for her phone. Before her feet touched the cold hardwood floor, before she’d taken a full breath, before her eyes had fully adjusted to the blue light of the screen, she was already reading emails. Three from her COO. Two from legal. One from a board member with a subject line that made her stomach clench.

She stood up. The room tilted slightly. Not vertically, more a soft lateral drift, like the room was on a boat in a mild swell. This had been happening for months. She’d seen her primary care physician, who ordered bloodwork and found nothing. She’d seen an ENT, who found nothing. She’d stopped mentioning it. The dizziness was just there now, another item in the long inventory of things her body did that she managed around.

She brushed her teeth. Her jaw ached. The nightguard her dentist prescribed sat untouched on the bathroom shelf because wearing it made her feel claustrophobic. She dressed in the dark, because her husband was still sleeping and she’d learned to move through the bedroom without making a sound. A skill she’d had since childhood, when making noise in the early morning was dangerous in her family home. She didn’t think about this connection. She just did it.

By 6:00 AM she was at her desk. By 6:45 she’d had her first moment of chest tightness. The one that comes when she thinks about the day ahead and something in her body says too much before her mind has even calculated the actual demands. By 7:30 she’d pushed past it. By noon she’d forgotten it entirely, because by noon she was deep in the current of her day and the current doesn’t allow for noticing anything except the next thing.

If you’d asked Dalia whether her nervous system was dysregulated, she would have looked at you blankly. She didn’t have the language. She didn’t have the framework. She had a successful career, a “normal” amount of stress, and a body that did annoying things she’d learned to work around. She was, in her own words, “fine.”

She was not fine. She was living in a state of chronic nervous system dysregulation that had become so normalized, so woven into the fabric of her daily existence, that it had become invisible to her. The way you stop hearing the hum of a refrigerator that’s been running your entire life.

In my clinical experience, this is the most dangerous form of dysregulation: the kind you don’t know you have. The kind that has been present for so long that it doesn’t register as a symptom. It registers as identity. “I’m just a tense person.” “I’ve always been a light sleeper.” “I’m not great at relaxing.” These aren’t personality traits. They’re signs that your nervous system has been operating in survival mode for so long that survival mode has become your baseline.

What Is Nervous System Dysregulation?

To understand dysregulation, we first need to understand what regulation looks like. Because for many people, especially those with chronic trauma histories, regulation is a theoretical concept rather than a lived experience.

A regulated nervous system is one that can move flexibly between states of activation and rest. It responds proportionally to stimuli. Getting appropriately activated in response to genuine stress and returning to baseline when the stress passes. A regulated system can tolerate a range of emotional and physical experiences without becoming overwhelmed or shutting down. It supports clear thinking, emotional flexibility, relational attunement, and the capacity for both action and rest.

Dysregulation, then, is the loss of that flexibility. The system becomes stuck. In activation, in shutdown, or in a volatile oscillation between the two. And loses its capacity to respond proportionally to the demands of the present moment. Small triggers produce large reactions. The system can’t settle after stress. Rest feels impossible, or collapse feels inevitable. The person’s baseline shifts from the window of tolerance to one of the zones outside it, and that zone becomes the new “normal.”

What makes dysregulation so pernicious is that it doesn’t feel like a discrete symptom the way a headache or a fever does. It’s not a thing you have. It’s a state you live in. It infiltrates everything. Your body, your emotions, your thinking, your relationships. And because it’s everywhere, it’s nowhere. You can’t isolate it. You can’t point to it and say, “There’s the problem.” The problem is the water you’re swimming in.

Deb Dana, LCSW, a clinician and educator who has done more than perhaps anyone else to make Polyvagal Theory accessible to both therapists and clients, describes it this way: a dysregulated nervous system is one that has lost its sense of home. The ventral vagal state. The place of safety and connection. Is supposed to be home base. But when the system is chronically dysregulated, it can’t find its way home. It’s wandering, lost, in the territory of fight-or-flight or freeze, unable to remember what safety feels like.

The Polyvagal Map: Three States and Their Signatures

Stephen Porges’s Polyvagal Theory provides the most clinically useful map for understanding nervous system states, and Deb Dana’s adaptation of this work into a practical framework. What she calls the “autonomic ladder”. Makes it accessible for anyone, not just clinicians.

The polyvagal model describes three primary states of the autonomic nervous system, each with a distinct set of physical, emotional, cognitive, and relational signatures:

Ventral vagal state (safety and social engagement). This is the regulated state. The home base. When the ventral vagal complex is active, the most recently evolved branch of the vagus nerve supports social engagement, clear thinking, and a felt sense of safety. Physically: heart rate is steady, breathing is deep and rhythmic, muscles are relaxed, digestion is functioning well, and the face and voice are animated and expressive. Emotionally: you feel calm, curious, open, capable, connected. Cognitively: you can think clearly, hold multiple perspectives, make decisions with reasonable confidence, and access creativity. Relationally: you can connect with others, feel empathy, maintain appropriate boundaries, and tolerate conflict without losing your sense of self.

Sympathetic state (fight-or-flight). This is the mobilization state. The system is activated in response to perceived danger and is preparing to fight or flee. Physically: heart rate increases, breathing becomes rapid and shallow, muscles tense (especially in the jaw, shoulders, and back), digestion slows or disrupts, skin may flush or become clammy, pupils dilate. Emotionally: you feel anxious, panicky, irritable, agitated, urgently focused. Cognitively: thinking narrows to threat assessment. You’re scanning for danger, catastrophizing, unable to see the big picture. Relationally: you may become reactive, confrontational, controlling, or hypervigilant about others’ intentions.

Dorsal vagal state (freeze/shutdown). This is the immobilization state. The oldest, most primitive survival response, mediated by the dorsal branch of the vagus nerve. Physically: heart rate drops, blood pressure lowers, breathing becomes shallow, muscles go limp or heavy, digestion may slow dramatically, you may feel physically heavy or numb. Emotionally: you feel flat, empty, hopeless, disconnected, “not here.” Cognitively: brain fog, inability to concentrate, difficulty forming sentences, lost sense of time, dissociation. Relationally: withdrawal, isolation, inability to connect, feeling like you’re behind glass watching others live their lives.

Why Driven Women Don’t Recognize Their Own Dysregulation

Here’s the thing I encounter most frequently in my clinical practice, and it’s the thing I most want to name in this article: driven women are often the last people to recognize their own dysregulation, precisely because their dysregulation has been the engine of their success.

Miriam is a perfect example. She’s a forty-one-year-old physician. An emergency medicine attending at a Level I trauma center. She saves lives. She makes split-second decisions under extraordinary pressure. She is, by any measure, someone who “handles” stress exceptionally well. And she came to therapy not because she recognized her nervous system as dysregulated, but because her husband told her he was thinking about leaving.

“He says I’m not present,” Miriam told me in our first session. “He says I come home and I’m physically there but I’m not actually there. He says it’s like living with a ghost.”

Her husband was describing dorsal vagal shutdown. Every evening, after twelve hours of sympathetic activation in the ER. The hypervigilance, the adrenaline, the rapid-fire decision-making that her job requires. Miriam’s nervous system crashed into the opposite extreme. She went numb. She couldn’t feel. She sat on the couch staring at the television without seeing it, her body in the room and her consciousness somewhere else entirely, while her husband and their two children moved around her like currents around a stone.

Miriam didn’t recognize this as dysregulation. She recognized it as tiredness. “I work long shifts,” she said, with the matter-of-factness of a woman who has rationalized her symptoms for years. “Of course I’m tired when I get home.”

But this wasn’t tiredness. Tiredness involves a body that wants to rest. This was shutdown. A body that had collapsed because its nervous system had spent all day in a survival state and had nothing left. There’s a qualitative difference between the pleasant fatigue of a hard day’s work and the blank, dissociative numbness of a nervous system that has been operating in emergency mode for twelve years. Miriam had lost the ability to distinguish between them because she’d been in the cycle so long.

What I see in driven women is a specific pattern of non-recognition that operates on multiple levels:

They’ve normalized their baseline. If you’ve been in sympathetic activation since childhood. If hypervigilance is your earliest memory, if scanning for danger is the first thing you learned. Then the activated state doesn’t register as dysregulation. It registers as normal. You don’t know what regulation feels like, so you have no reference point for recognizing its absence. It’s like asking a fish to describe water. The dysregulation is the medium you’ve always lived in.

Their coping strategies mask the symptoms. Driven women are spectacular at coping. The productivity, the exercise, the controlled eating, the meticulous scheduling, the relentless forward motion. These are all strategies that manage the symptoms of dysregulation without addressing the dysregulation itself. They’re effective enough that the underlying problem stays hidden. The woman who runs ten miles before dawn isn’t exercising because she loves running. She’s running because it’s the only thing that discharges enough sympathetic activation to get her to baseline. Take away the run, and the anxiety is unbearable.

The culture has rewarded their dysregulated state. The sympathetically activated woman. The one who’s always on, always available, always producing. Is the cultural ideal. She gets promoted. She gets praised. She gets called a “rockstar” and a “superwoman” and a “force of nature.” Nobody looks at the rockstar and says, “Your nervous system is in chronic fight-or-flight.” They say, “How do you do it all?” And the answer she doesn’t have is: Because my body doesn’t know how to stop.

They dissociate from body signals. Bessel van der Kolk’s research has demonstrated that chronic trauma disrupts the brain’s capacity for interoception. The ability to sense and interpret internal body signals. Many driven women with trauma histories are profoundly disconnected from their bodies. They don’t feel the tension in their shoulders. They don’t register the tightness in their chest. They don’t notice the shallow breathing. The body is sending signals. Constant, urgent signals. And the mind has learned to ignore them all, because in the original environment, paying attention to body signals was either useless (no one was going to help) or dangerous (showing distress made things worse).

A Comprehensive Inventory: Signs Mapped to Polyvagal States

What follows is the most detailed inventory I can offer. A mapping of specific signs and symptoms to the polyvagal states they reflect. I want this to be practical. I want you to be able to read through it and recognize yourself. Because recognition is the first step. You can’t regulate a system you don’t know is dysregulated.

Physical signs of sympathetic activation (fight-or-flight):

Chronic muscle tension, particularly in the jaw (clenching, grinding, TMJ pain), shoulders (they live near your ears), upper back, and hip flexors. A resting heart rate that’s higher than it should be. Shallow breathing or breath-holding that you only notice when someone points it out. Digestive problems. IBS-like symptoms, acid reflux, nausea before stressful events. Difficulty falling asleep because your body won’t settle, or waking at 3 AM with a cortisol spike and racing thoughts. Headaches. The tension kind, starting at the base of the skull or behind the eyes. Chronic fatigue that coexists paradoxically with an inability to rest. An exaggerated startle response. You jump at unexpected sounds or movements. Restlessness. The feeling of needing to be in motion, the inability to sit still, the compulsive fidgeting.

Emotional signs of sympathetic activation:

A pervasive sense of anxiety that isn’t tied to a specific threat. A floating unease, a sense that something bad is about to happen. Irritability that’s disproportionate to the trigger. The coworker’s question, the child’s request, the partner’s benign comment that triggers a surge of annoyance that makes no rational sense. Anger that arrives fast and fierce and then leaves you confused about where it came from. A sense of urgency about everything. The feeling that every task is time-sensitive, every email needs an immediate response, every problem needs solving now. Difficulty experiencing positive emotions. The joy is muted, the pleasure is distant, the accomplishment is immediately followed by “what’s next.”

Cognitive signs of sympathetic activation:

Racing thoughts. Not productive brainstorming but a mental hamster wheel of worst-case scenarios. Difficulty concentrating. Your attention is scattered, pulled in multiple directions by the nervous system’s scanning for threat. Hypervigilance. The constant monitoring of social environments for signs of danger (the boss’s tone, the partner’s expression, the friend’s delay in responding to a text). Catastrophic thinking. The small problem that your mind immediately escalates to a disaster. Difficulty making decisions. Every choice feels weighted with potential danger, and the nervous system’s threat response makes every option look risky.

Relational signs of sympathetic activation:

Controlling behavior. The need to manage other people’s actions, environments, and emotional states because uncontrolled variables feel dangerous. Conflict avoidance or conflict escalation. Either you can’t tolerate any friction (and people-please to prevent it) or you become reactive and combative when challenged. Difficulty trusting. The assumption that people will let you down, hurt you, or leave. Hyper-independence. The inability to ask for help, the insistence on doing everything yourself, because depending on someone feels like a risk your nervous system won’t take. Scanning other people’s emotional states. Monitoring their faces, their tone, their body language. And adjusting your behavior accordingly, constantly.

Physical signs of dorsal vagal shutdown (freeze/collapse):

A heaviness in the body. Limbs feel weighted, as if gravity has doubled. Low energy that isn’t improved by sleep or rest. Digestive slowing. Constipation, bloating, the feeling that your gut has stopped working. Cold hands and feet. The blood flow has shifted away from the extremities. A flat, expressionless face. Not by choice, but because the muscles that produce facial expression have disengaged. Slowed movements. Walking more slowly, reaching for things more slowly, a general deceleration that feels involuntary. Brain fog. The inability to think clearly, to form sentences, to remember what you walked into the room to do. Dizziness or lightheadedness. The room feeling unsteady, the ground feeling uncertain.

Emotional signs of dorsal vagal shutdown:

Numbness. Not just the absence of bad feelings, but the absence of all feelings. The world goes flat. Colors are muted. Music doesn’t move you. Things that should matter don’t register. A sense of hopelessness. Not active despair, but a dull, gray emptiness, a feeling that nothing will change and nothing matters. Disconnection from your own life. The feeling of watching yourself from outside, of going through motions that have no meaning. Shame. A deep, pervasive sense that something is fundamentally wrong with you, that you’re broken or defective in a way that can’t be fixed.

Cognitive signs of dorsal vagal shutdown:

Slow processing. Reading the same paragraph three times, unable to extract meaning. Difficulty finding words. Knowing what you want to say but being unable to access the language. Memory gaps. Forgetting conversations, appointments, or entire periods of the day. Dissociation. The sense of not being fully present, of being behind glass, of the world feeling dreamlike or unreal. Loss of future orientation. The inability to plan, to anticipate, to think beyond the present moment.

Relational signs of dorsal vagal shutdown:

Withdrawal. Pulling away from friends, family, and social engagement. An inability to feel empathy. You know you should care, but the caring isn’t there. Going through the motions in relationships. Saying the right things, performing the right gestures, without any genuine emotional connection behind them. A sense of being invisible, even in a crowd. Difficulty speaking. In meetings, in conversations, in therapy. The words won’t come, or they come out flat and lifeless.

If you recognized yourself in multiple items on this inventory. Particularly if you recognized them as things you’ve always assumed were “just who I am”. I want you to sit with that recognition for a moment. Because this may be the first time someone has told you: those aren’t personality traits. They’re nervous system states. And they can change.

Both/And: Being Dysregulated and Being Brilliant

I want to address something directly, because I know the driven women reading this are already thinking it: But I’m successful. I’m accomplished. I function at a very high level. How can my nervous system be dysregulated?

It can be both. You can be brilliant, accomplished, driven, and effective, and your nervous system can be chronically dysregulated. In fact, for many of the women I work with, the brilliance and the dysregulation are not separate phenomena. They’re connected. The same nervous system activation that produces the hypervigilance, the relentless work ethic, the refusal to slow down. That’s the sympathetic nervous system running in fight-or-flight. The same energy that built your career is the energy of a survival state that was never resolved.

This doesn’t diminish your achievements. It contextualizes them. It helps you understand why the achievements, as real and hard-won as they are, have never been enough to make you feel safe. Why the next promotion doesn’t settle the anxiety. Why the completed project doesn’t produce lasting satisfaction. Why you can have everything you’ve worked for and still feel, in your body, like something is wrong.

The feeling isn’t wrong. It’s your nervous system telling you the truth: that accomplishment and regulation are different things, and one doesn’t produce the other. You can’t achievement your way to a regulated nervous system. But you can bring your full intelligence, your full commitment, and your full courage to the work of healing. And that work will change not just how you feel, but how you live.

Dalia, the woman from the opening, eventually came to understand this. It took months. It took her beginning to notice her body. The dizziness, the jaw tension, the chest tightness. Not as annoyances to manage but as communications from a nervous system that had been screaming for attention for decades. It took her learning the polyvagal map and recognizing, with a mixture of relief and grief, that her “normal” wasn’t normal at all. It was survival.

“I’ve been in fight-or-flight my whole life,” she told me. “I thought that was just ambition.”

It wasn’t. It was her nervous system’s best attempt at keeping her alive in a world that didn’t feel safe. And it worked. She survived, she thrived, she built an extraordinary life. But the cost of running on survival energy for forty years was accumulating, and the body was starting to present the bill.

The Systemic Lens: Why We’ve Normalized Living in Survival Mode

I want to step back and look at this from the systemic perspective, because the normalization of nervous system dysregulation is not just an individual phenomenon. It’s a cultural one, and it’s worth naming the forces that keep it in place.

We live in a culture that has normalized chronic stress. Not just accepted it. Celebrated it. The hustle culture, the grind culture, the always-on culture. These are not just economic phenomena. They’re nervous system phenomena. They describe, and prescribe, a state of chronic sympathetic activation that the culture has rebranded as ambition, dedication, and work ethic.

When a culture normalizes sympathetic activation as the default state, it loses the capacity to recognize dysregulation. Because dysregulation becomes the norm. If everyone around you is running on adrenaline, your own adrenaline doesn’t register as a symptom. It registers as keeping up. If everyone around you is sleeping five hours a night, your own insomnia doesn’t register as dysregulation. It registers as being in the game.

For women, the normalization is compounded by additional layers. Women are socialized to manage their distress privately. To keep smiling, keep performing, keep caregiving. While the internal experience goes unwitnessed. The cultural expectation that women will handle emotional labor without complaint means that the symptoms of dysregulation are absorbed into the role rather than recognized as distress. The woman who is anxious and controlling at home is “type A.” The woman who crashes on the couch every evening is “just tired from doing so much.” The woman who can’t stop scrolling her phone at midnight is “addicted to her screen.” None of these framings point toward the nervous system. They all point toward the individual. Toward a perceived flaw that the woman is expected to manage through more discipline, more self-care, more effort.

The systemic lens offers a different framing: your dysregulation is not a personal failure. It’s a predictable outcome of a system that required too much of you too early and has continued to require too much of you ever since. The family system that didn’t provide adequate co-regulation. The educational system that rewarded performance over wellbeing. The professional system that equates burnout with commitment. The cultural system that tells women their worth is measured by their output.

These systems created the conditions for your dysregulation. Understanding that doesn’t excuse you from the work of healing. You’re the one living in your body, and you’re the one who’ll benefit from regulating it. But it does shift the frame from shame to clarity. It’s not, “What’s wrong with me?” It’s, “What happened to me, and what systems kept it in place?” That reframe is not just intellectually more accurate. It’s therapeutically more useful. Because shame perpetuates dysregulation, and clarity creates the conditions for change.

From Recognition to Regulation: The Path Forward

If you’ve read this article and recognized your own nervous system in these descriptions, I want to offer a clear path forward. Not a cure-all, but a direction.

Step one: Recognition. This is what you’ve just done. You’ve recognized that the tension, the insomnia, the irritability, the numbness, the brain fog, the relational difficulties. These aren’t personality traits or moral failings. They’re nervous system states. They have names. They have explanations. And they have trajectories of change. Recognition alone won’t regulate your nervous system, but it’s the indispensable first step. You can’t change what you can’t see.

Step two: Body awareness. Begin to notice your body, gently and without judgment. Not to fix anything. Just to notice. Where is the tension right now? What’s your breathing doing? Are your shoulders up or down? Is your jaw clenched or relaxed? This practice of interoception. Of turning attention inward. Begins to rebuild the bridge between mind and body that trauma disconnected. You can start with sixty seconds, once a day. Set a timer if you need to. It’s not meditation. It’s reconnaissance.

Step three: Learn your patterns. Begin to map your own polyvagal ladder. Notice when you’re in sympathetic activation (amped up, on edge, unable to rest) and when you’re in dorsal vagal shutdown (flat, numb, checked out). Notice what triggers the transitions. Notice how long you spend in each state. This mapping isn’t about controlling the states. It’s about understanding them. When you can name what’s happening (“I’m in sympathetic right now”), you create a tiny space between the state and your identity. You’re not “an anxious person.” You’re a person whose nervous system is in sympathetic activation. That distinction matters.

Step four: Begin co-regulation. Your nervous system learned dysregulation in the context of relationships, and it will learn regulation in the context of relationships. Therapy with a trauma-informed clinician who understands the nervous system is the most direct route. But co-regulation also happens in other relational contexts: with a partner who can hold space, with a friend who can listen without fixing, with a bodyworker who works with the nervous system, with a community that allows you to be fully human. Seek out the people and contexts that your nervous system registers as safe, and spend more time there.

Step five: Seek specialized support. If you recognize significant dysregulation in yourself. If the patterns I’ve described are chronic, pervasive, and impacting your quality of life. I strongly encourage you to explore trauma-informed therapy. The modalities with the strongest evidence base for nervous system regulation include Somatic Experiencing, Sensorimotor Psychotherapy, EMDR, IFS, and polyvagal-informed therapies. These approaches work with the body and the nervous system directly, not just the narrative, and they have the capacity to shift patterns that talk therapy alone often cannot.

Miriam, the ER physician, began therapy skeptically. She was a woman of science. She wanted data. She got it. Not from a study, but from her own body. Within three months of consistent somatic and polyvagal-informed work, her husband told her something she hadn’t heard in years: “You’re here tonight. You’re actually here.” She was. Her nervous system, for the first time, had enough regulation to come home from work and actually arrive. Not just physically, but in her body, in her heart, in the room with the people she loved.

That’s what nervous system regulation makes possible. Not the absence of stress. Stress is part of being alive, especially for driven women with ambitious lives. But the capacity to move through stress and come back to yourself. The capacity to feel things without being destroyed by them. The capacity to rest without guilt, to connect without armor, to be present in your own life instead of just performing it.

Your nervous system has been working overtime. It’s been doing its best with the equipment it was given, in the conditions it was given. And it’s tired. The recognition that it’s dysregulated isn’t an indictment. It’s an invitation. An invitation to finally give your body what it’s been asking for: safety, attunement, and the chance to learn, at last, what regulation actually feels like.

If you’re ready to explore what that could look like, I’m here.
