Calming the body activates the parasympathetic nervous system via the vagus nerve, shifting the body out of fight-or-flight mode. Research shows that bottom-up, body-based interventions — including breathing exercises, body awareness practices, and vagus nerve stimulation — effectively reduce anxiety and cortisol levels, often more quickly than cognitive strategies alone (Balban et al., 2023; Gerritsen & Band, 2018). Dr. Jaime Bercuson, PsyD, integrates these mind-body techniques with evidence-based CBT and DBT to treat anxiety in high-achieving women across Utah, California, and Florida.
You Can't Think Your Way Out of a Body That Feels Unsafe
You're lying in bed at 11:30 p.m. The lights are off, the room is quiet, and everything should feel calm. But your mind is anything but. It's racing through tomorrow's to-do list, replaying a conversation from three days ago, calculating whether you'll have enough time to get everything done. Your chest feels tight. Your jaw is clenched. Your breathing is shallow and quick without you even realizing it. You tell yourself to relax. You tell yourself it's fine, that you're being ridiculous, that there's nothing to worry about right now. But your body doesn't listen. Your heart keeps pounding. Your stomach stays knotted. And the harder you try to think yourself calm, the more awake and wired you feel.
This is one of the most common experiences my clients describe, and it points to something fundamental about how anxiety actually works. Anxiety is not just a thinking problem. It is a body problem, too. Your nervous system is stuck in overdrive, running a threat-detection program that doesn't have an off switch you can reach with thoughts alone. Your body needs to hear "safe" before your mind can settle. Until it does, no amount of rational self-talk will quiet the noise. That's not a personal failing. It's neurobiology. And understanding it is the first step toward a different relationship with anxiety.
Why "Just Think Positive" Doesn't Work When Your Body Is Screaming
There's a reason that telling yourself to "just think positive" or "stop worrying" almost never works when you're in the grip of anxiety. The answer lies in how your brain processes threat. Neuroscientists distinguish between two types of processing: top-down and bottom-up. Top-down processing is what happens when your prefrontal cortex — the rational, planning, decision-making part of your brain — evaluates a situation and decides how to respond. It's deliberate and conscious. Bottom-up processing, on the other hand, starts in the body and the lower brain structures, particularly the amygdala, which functions as your brain's alarm system. It's fast, automatic, and doesn't wait for permission from your rational mind.
When your body's stress response is activated — when you're in fight, flight, or freeze mode — the amygdala essentially hijacks your nervous system. Cortisol and adrenaline flood your bloodstream. Your heart rate spikes. Your muscles tense. And critically, your prefrontal cortex goes partially offline. This is what neuroscientist Daniel Goleman called the "amygdala hijack." Your thinking brain literally cannot function at full capacity when your body is in threat mode. This is why you can know intellectually that everything is fine and still feel terrified. The rational part of you understands there's no real danger, but the alarm system doesn't care about logic. It cares about survival.
This is also why cognitive-behavioral therapy, as powerful as it is, sometimes feels like it's not enough in the acute moment of panic or intense anxiety. CBT works brilliantly for identifying and restructuring the thought patterns that maintain anxiety over time. But when cortisol is surging and your body is screaming "danger," trying to restructure a thought is like trying to have a philosophical conversation during a fire alarm. You need to calm the body first. Then the cognitive work can land. Stephen Porges' polyvagal theory helps explain why: the vagus nerve — the longest cranial nerve in your body, running from your brainstem to your gut — functions as your body's primary "safety signal" system. When the vagus nerve is activated, it communicates to your brain that you are safe, shifting you from a sympathetic (fight-or-flight) state into a parasympathetic (rest-and-digest) state. Research consistently shows that bottom-up, body-based interventions can reduce cortisol levels and deactivate the stress response faster than cognitive strategies alone.
Your Nervous System Is Not Broken — It's Doing Its Job
Before we get into the tools, I want to pause here because this piece matters. If you're a high-achieving woman who lives with anxiety, you may have spent years feeling like something is wrong with you. Like you're broken. Like everyone else can handle things and you're the only one whose body won't cooperate. I hear this in my practice all the time, and I want to be direct: your nervous system is not broken. It is doing exactly what it was designed to do. It learned, probably a long time ago, that staying on high alert was the safest option. Maybe it learned that in childhood. Maybe it learned it in a high-pressure academic environment, or a demanding career, or a relationship where you had to anticipate someone else's needs to feel safe. The specifics vary, but the pattern is the same.
For high-achieving women, the nervous system has often been trained to stay hyper-vigilant because that vigilance produced results. You got the grades. You earned the promotion. You held everything together. Your body learned that scanning for problems and staying ten steps ahead was how you survived, and so it kept doing it — even when the original threat was gone. The tight jaw you carry all day. The shallow breathing you don't notice until someone points it out. The stomach knots that show up before every meeting. The way your shoulders live somewhere near your ears. These are not character flaws. They're not signs of weakness. They are a nervous system that learned it needs to stay on high alert to keep you safe.
The goal of this work is not to "fix" yourself, because you are not broken. The goal is to teach your body that it's safe to come down from high alert. That you can put down the vigilance without everything falling apart. That rest is not dangerous. This is a fundamentally different orientation than trying to think your way out of anxiety, and it changes everything about how the work feels.
Breathing — The Fastest Way to Talk to Your Nervous System
If there is one tool I could give every client on day one, it would be intentional breathing. Not because it's trendy or because "just breathe" is good advice (it's usually terrible advice when said dismissively). But because the vagus nerve responds directly to how you breathe, making your breath the single most accessible lever you have for shifting your nervous system state in real time. When you breathe slowly and deeply, particularly into your diaphragm rather than your upper chest, you activate the parasympathetic branch of your nervous system. Your heart rate slows. Your blood pressure drops. Cortisol production decreases. Your brain receives the signal: safe.
Diaphragmatic (belly) breathing is the foundation. Place one hand on your chest and one on your belly. Breathe in slowly through your nose, directing the breath so that your belly rises while your chest stays relatively still. Exhale slowly through your mouth. This activates the parasympathetic nervous system because it engages the diaphragm in a way that mechanically stimulates the vagus nerve. Most anxious breathing is the opposite — shallow, chest-based, and rapid — which keeps the sympathetic nervous system engaged. Simply shifting the location and pace of your breath changes your physiology.
The physiological sigh is a technique that has gained significant attention thanks to research from Stanford neuroscientist Andrew Huberman. It involves a double inhale through the nose — two quick sniffs, the second filling the lungs completely — followed by a long, slow exhale through the mouth. This pattern is actually something your body does naturally during sleep and crying, and it turns out to be one of the fastest ways to reduce physiological stress in real time. A 2023 study by Balban and colleagues published in Cell Reports Medicine found that just five minutes of daily cyclic sighing outperformed mindfulness meditation for improving mood and reducing respiratory rate and anxiety. That finding is remarkable: a simple breathing pattern, done for five minutes, was more effective than meditation.
Box breathing — inhaling for four counts, holding for four counts, exhaling for four counts, holding for four counts — is another evidence-based technique used by Navy SEALs, ER physicians, and first responders precisely because it works under extreme stress. The structured count gives your mind something to focus on while the slow, controlled breathing shifts your nervous system. And here's the part that surprises most of my clients: you don't need twenty minutes of breathwork to make a difference. Even 90 seconds of intentional breathing can measurably shift your nervous system state. Ninety seconds. That's less time than it takes to scroll through your phone. The key is that the breathing needs to be deliberate and intentional, not just a deep sigh and back to business. But the barrier to entry is remarkably low.
Body Awareness — Tuning In Instead of Checking Out
High-achieving women are often experts at ignoring their body's signals. You've trained yourself to push through the headache, power past the exhaustion, and ignore the knot in your stomach because there's work to be done. That capacity to override your body's messages served you well in the short term. But over time, it creates a disconnection between your mind and your body that actually makes anxiety worse. When you stop paying attention to your body's signals, you lose the ability to catch stress early, before it escalates into full-blown anxiety or panic. You miss the warning signs. By the time you notice something is wrong, you're already deep in it.
Body scan practice is one of the simplest and most powerful ways to rebuild this connection. You don't have to meditate for an hour or attend a retreat. A body scan can take three to five minutes. You simply move your attention slowly through different areas of your body — your jaw, your shoulders, your chest, your stomach, your hands, your legs — and notice what you find. The key word is notice, not fix. You're not trying to release the tension or make anything different. You're just becoming aware. Where does tension live in your body right now? What does it feel like? Is it sharp or dull, tight or heavy? This practice of simply paying attention, without judgment or agenda, is itself regulatory. It activates the prefrontal cortex and helps your brain process what your body is experiencing rather than staying stuck in a reactive loop.
Progressive muscle relaxation (PMR) takes this a step further by using the body's own physiology. You systematically tense a muscle group — say, your shoulders — hold the tension for five to ten seconds, and then deliberately release it. The release creates a rebound relaxation response that is deeper than what you can achieve by simply trying to relax. PMR works because it gives your nervous system a clear contrast between tension and release, training it to recognize and move toward the relaxed state. It's particularly effective for people who carry chronic muscle tension without realizing it, which describes most of my clients.
There's a term in neuroscience for this internal body awareness: interoception. It refers to your ability to perceive and interpret signals from inside your body — your heartbeat, your breathing, the sensation of fullness, the subtle cues of tension and relaxation. A 2012 study by Mehling and colleagues published in PLOS ONE found that better interoceptive awareness correlates with lower anxiety and improved emotional regulation. In other words, people who are more attuned to their body's internal signals are better equipped to manage difficult emotions. This isn't about becoming hyperaware of every sensation. It's about developing a baseline relationship with your body so that you can notice when something shifts and respond before it becomes a crisis.
Nervous System Regulation — Beyond the Breath
Breathing is the most accessible tool, but it's far from the only way to signal safety to your nervous system. The body has multiple pathways for activating the parasympathetic response, and having a range of options means you can find what works for you in different situations.
Movement and exercise are among the most well-documented interventions for anxiety. You don't need to run a marathon. Even a ten-minute walk shifts cortisol levels and increases the production of endorphins and GABA, a neurotransmitter that promotes calm. Movement also helps complete the stress cycle — your body has activated a fight-or-flight response, and movement gives it somewhere to go. Many of my clients find that a short walk between meetings or at the end of the workday makes a significant difference in their baseline anxiety level.
Cold water on the face or wrists activates what's known as the mammalian dive reflex — an ancient physiological response that slows your heart rate and redirects blood flow when your face contacts cold water. It also stimulates the vagus nerve. You don't need an ice bath. Splashing cold water on your face, holding a cold washcloth on the back of your neck, or running cold water over your wrists for thirty seconds can noticeably shift your nervous system state. This is a particularly useful tool in moments of acute distress because it works fast and requires no special equipment.
Humming, singing, or gargling may sound surprising as anxiety tools, but they work because the vagus nerve runs through the throat. When you hum, sing, or gargle vigorously, you mechanically stimulate the vagus nerve, which activates the parasympathetic response. Humming in particular is accessible anywhere — you can do it quietly at your desk, in your car, or before a difficult conversation. Grounding techniques like the 5-4-3-2-1 sensory exercise — naming five things you can see, four you can touch, three you can hear, two you can smell, and one you can taste — work by pulling your attention out of the anxious thought spiral and anchoring it in the present moment through your senses. Gentle stretching or yoga combines movement, breath, and body awareness in a way that is deeply regulatory for the nervous system. And social co-regulation — simply being in the presence of someone who feels calm — is one of the most powerful but least discussed tools. Your nervous system is constantly reading the nervous systems of people around you. Being with someone who is regulated can help your own system settle. A 2018 review by Gerritsen and Band in Frontiers in Human Neuroscience confirmed that vagal tone — the strength of your vagus nerve's activity — plays a central role in stress resilience, and that practices which improve vagal tone lead to measurable improvements in emotional regulation and stress recovery.
How This Shows Up in Therapy
In my sessions, we don't just talk about thoughts. We pay attention to what's happening in your body, too. When you notice your chest tighten as you describe a work situation, that's information. When your breathing goes shallow the moment you mention a particular relationship, that's data your body is offering about what matters and what hurts. Learning to notice these signals, rather than pushing past them, changes the entire depth of the therapeutic work.
CBT and DBT provide the framework — the tools for identifying thought distortions, building distress tolerance, regulating emotions, and changing patterns that keep you stuck. But body awareness is what makes that framework land deeper. When you learn to breathe through a stress response instead of white-knuckling your way through it, that's a skill you keep forever. When you can recognize that the knot in your stomach before a presentation isn't a sign that something terrible is about to happen but rather your nervous system doing its job, you respond differently. You stop fighting your body and start working with it. That shift — from adversarial to collaborative — is one of the most transformative things I see in my practice.
Your Body and Your Mind Are the Same System
You don't have to choose between your mind and your body. You don't have to decide whether anxiety is "physical" or "psychological," because it has always been both. The most powerful thing you can learn in therapy is that calming your body is calming your mind. They are not separate systems competing for your attention. They are one integrated system, and when you learn to work with that system rather than against it, anxiety stops feeling like an enemy you have to defeat and starts feeling like a signal you know how to read and respond to.
And once you have these tools — the breath, the body awareness, the understanding of what your nervous system is doing and why — they're yours to keep. They don't expire. They don't require a prescription. They work at 2 a.m. when you can't sleep, in the parking lot before a hard conversation, and in the quiet moment when you realize your jaw has been clenched for the last three hours. They meet you wherever you are, and they work every single time.
