Why Rest Feels Dangerous: The Neurobiology of Can’t-Stop-Working

THERAPY FOR DRIVEN WOMEN • July 20, 2026

The Vacation She Couldn’t Land In

In my work with clients, I hear some version of this sentence at least once a week: “I don’t know how to just stop.” Angela said it to me on a Tuesday afternoon in March, sitting cross-legged on my office couch with her laptop bag still on her shoulder, like she hadn’t decided yet whether this hour counted as a break or another obligation to get through efficiently.

Angela is forty-four, a VP of operations at a logistics company, three days back from a trip to Portugal that she had planned for eight months. “I had a spreadsheet,” she told me. “Restaurants, walking routes, backup restaurants in case the first ones were closed. I thought if I planned it well enough, I’d actually relax once I got there.” She laughed, but it wasn’t a real laugh. “I checked my email eleven times on the flight over. There’s no WiFi on that flight. I checked it anyway. Just in case.”

I want to be careful here, because this is exactly the kind of moment that gets flattened into a tidy explanation. It would be easy to say Angela’s inability to relax on vacation is a trauma response, full stop, case closed. But that’s not something I can know from one sentence in a first session, and it’s not something anyone can know about you from a blog post. Difficulty resting is one of the most common things driven women bring into therapy, and it is also one of the least specific. It can point in a lot of different directions, and figuring out which direction matters more than naming the problem quickly.

What I can say is this: the sensation itself, the tight chest, the compulsive checking, the guilt that arrives the moment your hands are empty, is real and worth taking seriously. Not because it always means something dire. Because it’s telling you something is asking for your attention, even if we don’t yet know what.

This piece is an attempt to walk through what’s actually known about stress, stillness, and the nervous system, where the science is solid, where it’s still being debated, and where good information stops and self-diagnosis starts. If you’ve ever sat on a beautiful vacation feeling like you were failing a test no one told you about, I hope this helps you understand your own experience with more precision, and less shame.

What Is the Resting Self?

In my clinical work, I sometimes use the phrase “the Resting Self” as a shorthand, not a diagnosis, for the part of a person that can be still without treating stillness as a problem to solve. It’s a descriptive concept, a way of naming a pattern I see often in my office. It isn’t a clinical entity with its own diagnostic criteria, and no single blog post, including this one, can tell you whether your particular experience of restlessness reflects an exiled capacity for rest, a demanding season of life, a medical issue, or several things layered on top of each other.

When I talk with clients about this, I try to slow down the instinct to immediately explain the pattern. A woman who can’t rest might be exhausted from an unsustainable season at work. She might be a new parent whose body hasn’t had unbroken sleep in fourteen months. She might have undiagnosed sleep apnea, a thyroid condition, or be running on caffeine in a way that keeps her physiologically wired long after she wants to wind down. She might be managing anxiety or depression that hasn’t been named yet. She might, yes, have a nervous system shaped by an earlier period of chronic stress or relational harm. Often it is more than one of these things at once. This piece can’t tell you which one is true for you. It can help you ask better questions.

What Difficulty Resting Can Actually Mean

Before we get into the neurobiology, I want to name the range of things that “I can’t rest” can actually reflect, because collapsing all of them into one narrative does a disservice to anyone reading this looking for answers.

A demanding season. Sometimes the honest answer is that your workload, caregiving responsibilities, or financial pressures are genuinely too much right now, and your body is responding accurately to real conditions. This isn’t a nervous system malfunction. It’s an accurate read of an unsustainable situation.

Habits and substances. Caffeine timing, alcohol use, screen exposure before bed, and irregular schedules all affect the body’s ability to downshift, independent of any psychological history.

Sleep disruption in its own right. Insomnia, sleep apnea, and other sleep disorders can produce daytime restlessness and an inability to relax that has nothing to do with an unresolved past and everything to do with an under-treated present-tense medical issue.

Mood and anxiety conditions. Generalized anxiety, panic-spectrum presentations, and depression can all produce an inability to settle, sometimes alongside irritability, appetite changes, or a persistent sense of dread that has its own diagnostic criteria and its own treatments.

ADHD. For some people, the restlessness that shows up as “can’t stop working” is better explained by attention and executive-function patterns than by a stress response at all.

Chronic pain. Pain that flares with stillness, or that makes lying down uncomfortable, can produce an avoidance of rest that looks behaviorally similar to what I’m describing in this piece but has an entirely physical driver.

Menopause and hormonal shifts. Perimenopause and menopause are associated with sleep disruption, night sweats, and mood changes that can make rest feel physically unreachable, independent of psychological history.

Thyroid, cardiac, or medication-related factors. Hyperthyroidism, certain cardiac arrhythmias, and the side effects of medications including some antidepressants, stimulants, and decongestants can all produce a wired, can’t-settle feeling that mimics psychological hypervigilance but requires a different kind of attention entirely.

Trauma-related hyperarousal. For some people, and this is where the rest of this article lives, a nervous system shaped by chronic early stress or relational harm can make stillness itself feel unsafe. This is real, it’s documented, and it’s also just one item on this list, not the default explanation.

Cultural and organizational demands. Some workplaces and cultural contexts actively reward the inability to stop and penalize rest. Sometimes the most accurate explanation is structural, not psychological at all.

I’m naming all of this here, at the front of the piece, because a huge percentage of what gets called “trauma-related overworking” online right now skips this step entirely. If you take nothing else from this article, I’d want you to take this: please don’t self-diagnose your way past a doctor’s appointment or a psychiatric evaluation because a framework felt emotionally resonant. Resonance is not the same as accuracy.

The Neurobiology of Stress and Stillness, With Real Caveats

I recently spent a few weeks going back through the research on stress physiology and rest, partly for my own clinical grounding and partly because I wanted this piece to hold up to scrutiny rather than just feel true. Here is what I found, along with where the science gets more uncertain than most wellness content admits.

Frank Corrigan, MD, a psychiatrist who has written on trauma and the autonomic nervous system, is the researcher I kept returning to while fact-checking this piece, because his 2011 review is refreshingly honest about the limits of the window-of-tolerance model rather than presenting it as an established fact.

Stephen Porges, PhD, a neuroscientist and the originator of Polyvagal Theory, has spent decades studying how the autonomic nervous system responds to perceived safety and threat, and his 2025 paper on the current status of the theory is worth reading in full if you want the primary source rather than a secondhand summary (PMID: 40735382). I want to be direct about something here, because I think the wellness internet has done Porges a disservice: Polyvagal Theory is an influential and clinically generative framework, and it is also genuinely debated within the scientific community, with some researchers raising questions about specific mechanistic claims even while broadly agreeing that the autonomic nervous system plays a role in how people experience safety and threat. I find parts of the framework clinically useful. I don’t present it to clients, or to you, as settled biological fact.

Bessel van der Kolk, MD, a psychiatrist and trauma researcher whose more recent work includes a 2024 study on self-experience in MDMA-assisted therapy for PTSD, has written extensively about how chronic stress can shift a person’s baseline physiological arousal (PMID: 38198456). What his research and others in the field describe is an association, a pattern seen often enough in trauma-exposed populations to be clinically significant, not a universal mechanism that explains every instance of restlessness in every person.

I want to name the caveat one more time because it matters: none of this research establishes that stress or trauma causes permanent, irreversible changes to your brain or body. The nervous system is more adaptable across the lifespan than that framing suggests, and claims about permanent “rewiring” or lasting adrenal damage from stress go further than the current evidence actually supports. What the research does support is that patterns learned over time can be unlearned over time, usually more slowly than anyone wants.

How This Shows Up in Driven Women

For the subset of driven women whose restlessness does trace back to a long stretch of chronic stress, whether from an unpredictable early environment, a high-stakes career, prolonged caregiving, or some combination, the pattern tends to show up in a few recognizable shapes. I want to describe them not as a checklist for self-diagnosis, but as a way of helping you notice your own experience with more specificity.

The productive-only leisure. Rest gets smuggled in disguised as achievement. A walk becomes marathon training. A novel becomes a business book. Every hobby needs a metric attached before it feels permissible.

The unstructured-day dread. Weekdays with clear demands feel more tolerable than a Saturday with nothing on the calendar, because the empty day removes the structure that had been organizing the anxiety.

The delayed collapse. The body seems to wait until a project ends, a deadline passes, or a trip finally starts before symptoms show up, a headache, a cold, a wave of exhaustion that arrives exactly when things were supposed to get easier.

If these patterns sound familiar, that’s useful information. It’s not, on its own, a diagnosis of anything. It’s a starting point for a more specific conversation, ideally with a therapist or physician who can actually assess your individual situation rather than a blog post that, by definition, can’t.

Christine’s Story: When Can’t Stop Meets a Body Asking for Help

Christine came to see me two years ago, forty-one years old, a director of client services at a mid-size consulting firm, and she opened our first session by telling me she thought she had a trauma-driven inability to rest. She’d read about it. She’d taken an online quiz. She was fairly sure she knew her own diagnosis before she sat down.

“I can’t turn my brain off,” she told me, tapping her fingers against her knee in a rhythm that never quite stopped. “I haven’t slept through the night in maybe a year. I’m exhausted and wired at the same time, all the time. I know it’s my childhood. I know it’s the anxiety I’ve always had about being enough.”

I believed her that something was wrong. I did not assume I already knew what it was. Over the next several sessions, as we talked through her history and her physical symptoms in more detail, a few things emerged that had nothing to do with childhood: she had lost twelve pounds without trying, her resting heart rate had crept up, and she described a fine tremor in her hands that she’d attributed to caffeine. I asked her, gently and directly, whether she’d had recent bloodwork. She hadn’t, not in three years.

Her physician diagnosed hyperthyroidism a few weeks later. Her “can’t stop working” pattern was real, but a meaningful piece of the physical restlessness she was experiencing had an endocrine cause that talk therapy alone was never going to touch. Once her thyroid levels were medically managed, the wired, sleepless quality of her days changed substantially, though we still had real psychological material to work through around her relationship to achievement and rest, which had its own roots and its own timeline.

I tell this story because it’s the story I most want driven women to hear right now, in a cultural moment saturated with confident nervous-system content. Christine’s instinct to look for a psychological explanation wasn’t wrong. Her mistake, an understandable one, was skipping the medical workup because the psychological story felt more emotionally coherent and available. Both things were true for her. The thyroid needed a doctor. The relationship with rest needed a therapist. Neither one substituted for the other.

Angela’s Return: A Demanding Season, a Pattern, or Both

When Angela came back a few weeks after that first session, the one where she described checking her email eleven times over the Atlantic, we spent most of the hour trying to sort her experience into its actual components rather than one big explanation.

Some of it, we determined together, was situational. She had taken on a second team six months earlier without a raise or additional support, and she was, in plain terms, doing two jobs. “Of course you’re exhausted,” I told her. “You’re not broken. You’re carrying an unreasonable amount, and your nervous system is responding accurately to that.” That part of her restlessness wasn’t a childhood wound reasserting itself. It was math. Too much work, not enough hours, an accurate signal from a body under real strain.

But there was another layer underneath it, one that had been there long before this particular job. Angela described growing up as the oldest of four children in a household where her mother’s mood could shift without warning, and where being useful, watching her younger siblings, managing the house, staying quiet, was the reliable way to keep things calm. “I don’t think I ever learned that stopping was safe,” she said. “Even as a kid. If I wasn’t doing something, I was watching for what was about to go wrong.”

What I said to Angela, and what I’d say to you if you recognize any of this, is that both things can be true without one canceling out the other. Her job situation was genuinely unsustainable and needed to change regardless of her history. Her harder time downshifting even when the job situation improved likely had older roots that no amount of delegating was going to fully resolve on its own. Neither explanation required the other to be false.

Both/And: You Can Want Rest AND Feel Unsafe Slowing Down

One of the more disorienting experiences for driven women is wanting a break with your whole body and also feeling something like alarm the moment you actually stop. You book the trip. You block the calendar. And then you spend the first three days of the vacation answering emails you don’t technically need to answer.

We have to practice the Both/And here. You can be legitimately, bone-tired exhausted and want rest more than almost anything, AND some part of you can experience the vulnerability of stillness as genuinely uncomfortable or even alarming. Neither one cancels the other out, and neither one means you’re doing this wrong. Your struggle is legitimate, whatever combination of causes turns out to be true for you.

This doesn’t mean every urge to check your phone at the pool is a trauma response that needs unpacking. Sometimes it’s just a habit, or a genuinely demanding job, or a nervous system that hasn’t had a chance to recalibrate yet from a hard season. You don’t need a dramatic explanation to justify giving yourself permission to actually rest.

The Systemic Lens: The Economy That Profits From Your Inability to Stop

It would be incomplete to talk about individual nervous systems without naming the culture those nervous systems operate inside. Anne Helen Petersen, a journalist, wrote about this directly in her book on millennial burnout, describing how contemporary work culture often equates exhaustion with devotion and treats constant availability as a moral virtue rather than a sign that something has gone wrong.

I see this in my practice constantly: women who are promoted, praised, and financially rewarded for the exact behaviors that are quietly wearing them down. When the system around you actively benefits from your inability to stop, and rewards you for demonstrating it, it becomes genuinely difficult to tell the difference between ambition and a body that has forgotten how to downshift. This isn’t a reason to distrust your own experience. It’s a reason to be skeptical of any workplace culture that treats your exhaustion as evidence of your value.

This systemic reality doesn’t mean every individual case of restlessness is caused by capitalism, any more than it means every case is caused by childhood. It means the water you’re swimming in matters when you’re trying to figure out what’s actually going on in your own body, because a culture that rewards overwork will rarely be the one that helps you recognize when you need to stop.

When to Seek Medical or Mental Health Support

Because this article covers a wide range of possible explanations for difficulty resting, I want to be concrete about when it’s time to bring in outside support rather than continuing to read and self-reflect.

See a doctor if: your restlessness is accompanied by unexplained weight change, a racing or irregular heartbeat, tremor, night sweats unrelated to your environment, or any new physical symptom alongside the sleep and rest difficulty. A basic medical workup, including thyroid function, is a reasonable first step for almost anyone with persistent, unexplained restlessness.

See a mental health professional if: the difficulty resting is accompanied by persistent low mood, loss of interest in things you normally enjoy, panic symptoms, intrusive worry you can’t redirect, or if it’s been going on for months without improvement despite reasonable efforts to address it. A therapist can help sort out how much of the picture is trauma-related, how much is anxiety or mood-related, and how much is something else entirely, which is a more accurate process than any self-assessment.

Seek urgent or emergency care if you experience: chest pain, fainting or near-fainting, severe difficulty breathing, a racing heart that doesn’t settle, or symptoms of mania (racing thoughts, decreased need for sleep over several days, impulsive decisions that feel out of character). These require medical evaluation, not a wellness framework.

If sleep loss becomes dangerous, meaning you are experiencing confusion, hallucinations, or an inability to function safely, that is also a reason for same-day medical attention, not something to wait out.

If substance use is involved, whether alcohol, stimulants, or anything else you’re using to manage the restlessness or force yourself to sleep, that’s worth naming to a doctor or therapist directly rather than managing alone.

If you are having thoughts of suicide or self-harm, please reach out right away. In the United States, you can call or text 988 to reach the Suicide & Crisis Lifeline, any time, for free, confidentially. You deserve support, immediately, not eventually.

Reclaiming the Resting Self: What Support Can Look Like

I want to be honest about something before closing this out: I can’t promise you that reading this article, or even doing months of therapy, will make rest feel easy. I don’t make that promise to clients either, because it isn’t true for everyone, and false promises are their own kind of harm.

What I can say is that for the driven women I’ve worked with whose restlessness turned out to have a real trauma-related component, the process of learning to rest tends to happen slowly and in small doses, not through one insight or one vacation done differently. It often starts with tiny amounts of stillness, a few minutes rather than a few hours, because trying to go from constant motion to a silent retreat weekend tends to backfire.

Angela, several months into our work together, described a moment that stuck with me. She’d sat on her porch for ten minutes on a Sunday morning without her phone, and instead of dread, she’d mostly just felt bored. “Bored felt like a win,” she told me. “I didn’t know boredom could feel like progress.” I think about that sentence often. Progress in this work rarely looks dramatic. It looks like ten minutes on a porch, and boredom instead of alarm.

Christine’s path looked different, because a real piece of her restlessness had a medical driver that needed medical treatment first. Once that was addressed, the psychological work became clearer and more specific, less tangled up with symptoms that weren’t actually about her history at all.

If any part of this article resonated with your own experience, I’d encourage you to treat that resonance as a starting point for a real conversation, with a doctor, a therapist, or both, rather than a finished diagnosis. If you’re looking for a place to start that conversation, you’re welcome to look into therapy with me, or into my course on relational patterns and rest, Fixing the Foundations™, which explores some of these dynamics at a deeper level for people who’ve already ruled out or addressed the medical and situational pieces.

You don’t owe anyone, including yourself, a dramatic story to justify needing rest. Sometimes the most useful thing you can do is get the bloodwork, talk to a professional, and give the actual, specific version of your own situation the attention it deserves.
