You know the sensation, even if you have never named it. You are moving through your day. Meetings are happening. You are handling things. You look fine to everyone. And underneath, there is a hum. A tightness in your chest that never fully leaves. A jaw that is set. A breath that is short. A background readiness for something, though nothing in particular is coming.
At the end of the day, when you finally sit down, the hum does not stop. You try to relax. Your body does not know how. You scroll. You watch. You have a drink. You go to bed too late. You wake up early because your body is still running.
This is what a dysregulated nervous system feels like from the inside. It is the state most of the high-functioning people I work with in my Manhattan practice are living in, without knowing that it has a name or that anything can be done about it.
I am Jessica Esposito, LCSW, an EMDR-certified therapist. This article is for the person who has been reading about nervous system regulation on the internet, is tired of the wellness-influencer version of the topic, and wants a real explanation of what is actually happening in your body and what therapy can actually do about it.
What “nervous system regulation” actually means
The phrase has become fashionable. That does not mean it is fake. It means most of the writing about it has flattened a real, useful clinical concept into something vague enough to sell you something.
Here is the real version.
Your autonomic nervous system, the part of your body that runs without your conscious control (heart rate, digestion, breathing, immune response), operates in a few different states. The polyvagal theory framework, developed by Dr. Stephen Porges, describes three main ones:
Ventral vagal (regulated, social, connected). This is the state where you feel safe enough to engage with the world. You can rest. You can enjoy your food. You can connect with people. You can think clearly. You can have hard conversations without losing yourself. Your body is not in threat mode.
Sympathetic (activated, fight or flight). This is the state where your body has decided there is danger, and it needs to mobilize. Heart rate up. Breath shallow. Muscles tight. Focus narrowed. This state is not bad. It is how you get out of the way of a bus. The problem is when it becomes your baseline.
Dorsal vagal (shutdown, collapse, freeze). This is the state your body enters when the threat is too big or too long-lasting to fight or flee. It looks like exhaustion, numbness, disconnection, depression, inability to feel motivated. This state, too, is not bad on its own. It is a protection. The problem is when your body cannot get out of it.
A regulated nervous system is not one that is always in the ventral vagal state. It is one that can move flexibly between states as circumstances require, and reliably return to the regulated state when the demand passes. Dysregulation is what happens when the movement between states gets stuck: you either live in sympathetic (chronic activation) or collapse into dorsal vagal (chronic shutdown), and cannot get back.
If you are reading this and recognizing yourself, you are likely stuck in sympathetic. That is what most high-functioning people, especially those with any trauma or attachment history, are dealing with.
How you got here
Nervous system dysregulation is almost never about the present moment. It is about accumulated experience.
A few of the most common paths to a chronically activated nervous system:
Complex trauma or attachment wounds in childhood. If you grew up in a home where you had to stay alert for a caregiver’s mood, or where care was unpredictable, or where any part of you had to be managed to stay safe, your body learned that being on was survival. That wiring does not go away when you leave the house. It comes with you, into your relationships, your career, your mornings, your Sundays.
Chronic professional demand without integration. If your career has, for a decade or two, demanded that you perform at a high level regardless of what your body was signaling, your nervous system may have adapted by turning off the signals. You do not know you are exhausted until you crash. You do not know you are hungry until you are hangry. You do not know you are anxious until you cannot sleep. The signals still exist. You have learned to ignore them, and your body has learned to shout louder.
Cumulative unprocessed events. A layoff. A death. A move. A breakup. A pandemic. A conflict that was never resolved. Each event, if not fully metabolized, leaves a residue in the nervous system. Enough residues stack up, and the baseline shifts.
A specific trauma or series of traumas. Sometimes there is an event or set of events (medical, relational, violent, sudden) that shifted your nervous system from regulated to dysregulated, and it has never fully returned. This is what PTSD and complex PTSD sit on top of.
The self-medicating loop. Alcohol, cannabis, food, exercise, screens, and work can all be ways of down-regulating a nervous system that will not down-regulate on its own. They work in the short term. They also usually deepen the dysregulation over time, because the nervous system loses the capacity to self-soothe.
What dysregulation actually looks like in day-to-day life
Some of the most common features I hear in first sessions from Manhattan clients who turn out to have dysregulated nervous systems:
- You cannot fully relax on vacation. It takes three days to start unwinding and by then it is time to go home.
- You have trouble falling asleep because your mind will not stop. Or you fall asleep instantly out of exhaustion and wake at 3 AM wired.
- You feel anxious in situations that should not be stressful (Sunday nights, quiet moments, downtime).
- You have digestive issues, jaw tension, or unexplained physical symptoms that no doctor has fully solved.
- You feel a chronic low-grade dread that you cannot attach to anything specific.
- You crash on the weekends and cannot get out of bed even though you slept.
- You are irritable in ways that feel disproportionate to the trigger.
- You have trouble receiving good news (a compliment, a win) without immediately deflecting or minimizing.
- You struggle to be with other people’s emotions when they are big, even people you love.
- You feel like you are always slightly behind, even when you are actually caught up.
- You cannot stop working because stopping feels worse than continuing.
None of these are moral failings. They are all signals of a nervous system that has been asked to run in the on position for too long.
Why “just meditate” does not work (for most people)
You may have tried the standard advice. Meditate. Breathe. Do yoga. Get more sleep. Exercise. Cut back on caffeine. Take up journaling.
If it worked, you would not be reading this article.
The reason these tools often fail people with dysregulated nervous systems is that they are all top-down interventions. They ask your mind to tell your body to change. Your body, however, is not being driven by your mind. It is being driven by patterns that were laid down before your mind had much say. Asking your mind to fix your body’s nervous system is like asking a passenger to drive the car.
What actually shifts nervous system regulation is bottom-up work: interventions that speak to the body first, and let the mind catch up second. This is what somatic therapy, polyvagal-informed work, and body-based trauma therapies are designed to do.
What actually helps
Meaningful nervous system regulation work does a few specific things.
Increases your capacity to notice what state you are in. Most dysregulated people cannot tell you, in a given moment, whether they are activated, shut down, or regulated. Getting fluent in reading your own state is where the work starts. This is a real skill and it takes practice.
Builds real-time tools for coming back to regulation. Not generic tools. Tools that work for your specific nervous system, in your specific life. For some people this is breath work. For others it is orienting exercises (visually scanning the room slowly). For others it is grounding through the body (feet on floor, hand on chest). The right tools are the ones your body actually responds to.
Processes the accumulated residue. If your dysregulation is trauma-informed, the underlying material has to be processed, not just managed. This is where approaches like EMDR and somatic experiencing come in. Talking about the events is not the same as processing them. Processing is a body-level shift, and it requires body-level work.
Repairs the relationships that reinforce dysregulation. Sometimes the dysregulation is being fed by current relationships (a demanding boss, a chronically activating partner, a family system that pulls you back into old patterns). Part of the work is looking honestly at what is currently keeping you in sympathetic, and making choices about it.
Rebuilds the capacity to be with rest. For many high-functioning clients, the hardest part of regulation is not the acute work. It is the daily practice of letting yourself feel rested, feel enough, feel present without a to-do list. This is often the most transformative part of the work.
What this looks like in my practice
My approach to nervous system work is integrative. I use polyvagal-informed psychoeducation (helping you understand what is happening in your body), somatic techniques (working with breath, body awareness, and grounding), EMDR (for processing accumulated trauma and stuck material), and attachment-focused work (because much dysregulation traces back to early relational patterns).
Sessions are usually weekly via telehealth across New York and Connecticut.
This work is not fast. Meaningful shifts often start in the first month or two. Deeper regulation, the kind that changes your baseline permanently, typically takes months of consistent work. The people I have watched do this well come out on the other side with a different relationship to their body, their work, their relationships, and their capacity to rest. It is real, and it is worth every session.
Signs you might be a good fit for this work
Consider reaching out if:
- You recognize yourself in this article and are tired of it
- You have tried the standard tools (meditation, exercise, sleep hygiene) and know they are not enough
- You are ready to look at how your history is shaping your present, not just manage the symptoms
- You are willing to do work that involves your body, not just your thoughts
- You are prepared for this to be a real investment of time and consistency, not a quick fix
- You want to actually feel like a person in your own life again, not just perform being one
You do not have to be in crisis. You do not have to hit a wall first. In fact, this work is best done before the wall, not after.
FAQ
Is this the same as therapy for anxiety? Related but broader. Anxiety is one expression of dysregulation. Nervous system work addresses the underlying state, which affects anxiety, sleep, relationships, physical health, and general capacity to be present.
Is polyvagal theory science or is it wellness talk? Polyvagal theory is a real clinical framework developed by Dr. Stephen Porges. It has become popular in wellness circles, sometimes in ways that oversimplify it. The clinical version, used by trained therapists, is grounded in neuroscience and years of research.
How is this different from breathwork or yoga? Breathwork and yoga can absolutely support nervous system regulation, and I encourage clients to use them. The difference is that therapy can also process the underlying trauma and relational patterns that are keeping the dysregulation in place. Breathwork and yoga manage the state. Therapy can shift the baseline.
Do I have to have “trauma” to benefit from this work? No. Many people with chronically dysregulated nervous systems do not identify as trauma survivors. Sustained professional demand, cumulative stress, and unprocessed life events are enough to warrant this work, even without a specific traumatic history.
How long does this take? Meaningful shifts often start in the first month or two. Deeper baseline change typically takes months to a year of consistent work.
Can I do this work over telehealth? Yes. Most somatic and polyvagal-informed work is fully doable over telehealth. I offer sessions across New York and Connecticut.
You are allowed to slow down
If you have read this far, some part of you already knows what you are choosing when you keep running.
The nervous system that has kept you going is the same nervous system that is asking, in the ways it knows how, to be given something back. That request is not weakness. That request is what makes you human, and it is worth listening to before your body has to shout louder than it already is.
