Anxiety that feels physical, not just mental?
If your anxiety shows up in your body, not just in your head, a feeling that won’t switch off and therapy, medication, or breathing exercises haven’t fully calmed it, there may be a physical piece worth checking: your nervous system, and the part of your neck that helps regulate it.
15 minutes to find out if we can help your anxiety.
Sound like you?
A lot of the patients we help describe a version of the same thing.
See if any of these feel familiar.
- Your anxiety is physical as much as mental. A racing or pounding heart, chest tightness, shallow breathing, a knot in your stomach.
- You’ve already tried therapy, medication, breathing exercises, or meditation, and they’ve helped some, but your body still won’t fully settle.
- Your sleep is light or broken. You wake up already tense, or your mind switches on the moment your head hits the pillow.
- You feel wired but exhausted at the same time, like your body can’t downshift even when you’re tired.
- It often comes with physical symptoms like neck and shoulder tension, headaches, or a sense of being “on alert” for no clear reason.
- Calming your thoughts doesn’t calm your body. The physical sensations seem to run on their own track.
- It may have started or worsened after a period of high stress, an illness, or a head or neck injury, though sometimes there’s no clear trigger.
If several of those describe you, there may be a physical reason. The next section explains what we mean.

The anxiety & nervous system connection
The short answer:
Your nervous system has two modes; rest and digest & fight or flight. Anxiety that lives in your body is often a sign it’s stuck in fight or flight.
The longer answer:
Your autonomic nervous system runs everything you don’t think about: heart rate, breathing, digestion, balance, the tension in your muscles. It has two modes. One is fight or flight, your body’s accelerator, meant for short bursts of stress. The other is rest and digest, your body’s brake, where you recover, sleep, and heal.
In a healthy system, you shift between the two all day. But sometimes the system gets stuck in fight or flight and can’t fully shift back. When that happens, the physical symptoms you know take over: a racing heart, shallow breathing, muscle tension, broken sleep, and a constant sense of being on alert. That stuck, accelerator-dominant state is called sympathetic dominance.
Why your neck is part of this conversation
The switch between these two modes is regulated in your brainstem, which sits directly above the top of your neck. The uppermost vertebrae, C1 and C2 (atlas and axis), and the nerves around them are closely connected to the structures that govern autonomic balance, including the vagus nerve, the body’s main rest and digest pathway.
When the upper neck is irritated, stiff, or misaligned, it can feed a steady stream of stress signals into that system. For some people, that’s one of the inputs keeping the body tipped toward fight or flight.
How we measure this today: thermography
You can’t see “stuck in fight or flight” directly, but you can measure it. The tool we use is thermography.
Thermography is a test that measures your autonomic nervous system: the same part that turns fight or flight on and off. Thermography testing can show us if your system is adapting or stuck. Being stuck in fight or flight is called sympathetic dominance.
It works because the nervous system controls blood flow to your skin, so the temperature pattern along your spine becomes a readout of how your nervous system is regulating. A calm, adaptive system and a stuck, activated one produce different patterns. The test is quick, non-invasive, and uses no radiation.
Another window: heart rate variability
Thermography is what we measure in our office. Research on the nervous system and anxiety also relies heavily on a second objective measure you may have heard of: heart rate variability, or HRV.
HRV is the natural variation in time between your heartbeats. A healthy, adaptable nervous system produces more variability, a sign your rest and digest brake is working. A system stuck in fight or flight tends to show lower HRV and a higher resting heart rate.
This connection is well established. A 2014 meta-analysis in Frontiers in Psychiatry found that anxiety disorders are associated with reduced heart rate variability, a marker of reduced activity in the body’s rest and digest system.
Putting it together
Here’s the honest version of what this means. We are not saying a neck problem is the cause of anxiety, or that addressing the neck is a treatment for anxiety. Anxiety is complex, and it deserves real mental-health care.
What we are saying is narrower and testable: if your nervous system is stuck in fight or flight, and an upper neck problem is one of the things keeping it there, that’s a physical contributor worth identifying. Research has shown that upper cervical care can shift HRV toward the rest and digest side. For the right person, addressing that input may help the body do what it’s supposed to do: settle.
That’s the piece most anxiety care never checks. Our free nervous system test uses thermography to look at exactly this: whether your nervous system is stuck in fight or flight.

What we do differently
If your anxiety is significant, the standard path makes sense: talk to your doctor, work with a therapist, and consider medication if it’s warranted. Therapy and medication help a lot of people, and for many they’re essential. We’re not a replacement for any of that.
But that path is built around the mind and brain chemistry. What it usually doesn’t include is a look at the physical side of your nervous system: whether your body is stuck in fight or flight, and whether something in your upper neck is helping keep it there.
That’s the piece we check.
A protocol, not a guess
We work from a defined protocol. Every new patient goes through the same diagnostic sequence:
- Functional nervous system testing using thermography, which measures whether your nervous system is stuck in fight or flight
- A clinical exam of the upper cervical spine, including range-of-motion testing and palpation of the upper neck
- Biomechanical x-rays of the upper neck, read by a board-certified radiologist
- A review of your history and symptoms to identify whether upper cervical involvement may be contributing to your nervous system staying in fight or flight
If we find a physical contributor we can address, we explain exactly what care would look like. If we don’t, we tell you, and we point you back toward the care that’s most likely to help.
Less interference, not more intervention
When upper cervical chiropractic care is the right fit, the approach is precise rather than repetitive. We’re not adjusting your whole spine on every visit. We’re looking to make a specific adjustment to your C1 or C2 (atlas or axis) that helps your nervous system shift back out of fight or flight. Then we monitor, and we adjust again only when your body shows us it needs us to.
This is different than general chiropractic care. It requires precision and the discipline to stop adjusting when the body is healing.
What testing looks like
The free nervous system test we offer isn’t a sales pitch. It’s real diagnostic work, and it’s how we figure out whether a physical nervous system problem is part of what you’re dealing with.
Thermography
Thermography is a test that measures your autonomic nervous system: the same part that turns fight or flight on and off. Thermography testing can show us if your system is adapting or stuck. Being stuck in fight or flight is called sympathetic dominance.
The test is quick, completely non-invasive, and uses no radiation. You sit still. A specialized thermal sensor measures temperature patterns along your spine. We read the pattern, and we explain what it means.
If the pattern shows your nervous system is regulating normally, we tell you. If the pattern shows sympathetic dominance and possible upper cervical involvement, we tell you that too, and we move to the next step in the assessment.
Biomechanical x-rays
If thermography suggests upper cervical involvement, the next step is biomechanical x-rays of the upper neck. These aren’t standard general-practice x-rays. They’re taken at specific angles designed to measure the position and movement of your C1 and C2 vertebrae (atlas and axis).
Every x-ray we take is read by a board-certified radiologist. We don’t make the call alone. The radiologist’s report becomes part of your file, and we walk through it with you before any care begins.
Clinical exam
Thermography and imaging tell part of the story. A hands-on clinical exam tells the rest. We assess:
- Range of motion in your upper neck
- Posture and how your head sits over your neck and shoulders
- Muscle tension and tenderness through the neck and the base of the skull
- Palpable restriction at the C1-C2 level
When several of these line up with your history and your thermography pattern, it’s a strong indication that the upper neck is part of what’s keeping your nervous system on alert.
Will this work for you?
We don’t take every patient who walks in. The point of the free nervous system test is to find out, honestly, whether a physical nervous system problem is part of what you’re dealing with. For some people it is, and they’re good candidates for upper cervical chiropractic care. For others it isn’t, and we’d rather tell you that upfront than waste your time.
It’s most likely to help if…
- Your anxiety is physical as much as mental: racing heart, chest tightness, muscle tension, a body that won’t downshift.
- Your thermography shows your nervous system is stuck in fight or flight.
- You also have neck tension, stiffness, or a history of head or neck injury.
- You’re already getting appropriate mental-health support, and you’re looking to address a physical piece that hasn’t been examined.
We need to pause if…
- Your anxiety is severe, or you’re in crisis. Please reach out to your doctor, a mental-health professional, or a crisis line first. That care comes first, and it’s not something we provide.
- Your testing shows your nervous system is regulating normally and there’s no sign of upper cervical involvement. If that’s the case, we’ll tell you honestly, and upper cervical care isn’t the right tool for you.
- You’re looking for a replacement for therapy or medication. We’re not that. At most, we address a physical contributor alongside the care you’re already getting.
This is not mental-health care
We want to be very clear about our role. We are upper cervical chiropractors. We don’t diagnose or treat anxiety as a mental-health condition, and we’re not a substitute for therapy, medication, or psychiatric care.
What we do is check whether your nervous system is stuck in fight or flight, and whether a problem in your upper neck is part of what’s keeping it there. For the right person, addressing that physical piece can help the body settle, which may support everything else you’re doing. Think of us as one part of a bigger picture, not the whole answer.
No magic bullets
Even when upper cervical chiropractic care is the right fit, we can’t promise it will resolve your anxiety. What we aim for is a calmer, more regulated nervous system: better sleep, less physical tension, and a body that can finally shift out of high alert.
If a clinic promises to cure your anxiety with an adjustment, be skeptical. Nobody can promise that. We won’t either.
