AND What Your Chatswood Chiropractor Wants You to Know
Let me ask you a question, have you ever felt stressed?
And then noticed your shoulders creeping up toward your ears, your neck going stiff, or your whole body just feeling ‘off’?
That’s not a coincidence. And it’s not ‘just in your head’ either.
That tension you’re feeling is your nervous system at work — and as a chiropractor in Chatswood, I see the physical consequences of chronic stress every single day in my practice.
I’m Dr Brett Grant from Family Chiropractic Chatswood, and in this post I want to break down exactly what’s happening in your body when you’re stressed — and what we can do together to help you build what I like to call your body’s ‘suit of armour’ against stress.
The Stress Response — What’s Actually Happening in Your Body
When your body perceives stress — whether that’s a looming deadline, a difficult email, or a long commute — it activates what we call the sympathetic nervous system.
You might know it by its more common name: fight or flight.
The fight or flight response is a brilliant survival mechanism. It was designed to help your ancestors escape predators and survive physical danger. When triggered, it:
- Increases heart rate and blood pressure
- Sends blood to your muscles so you can fight or run
- Contracts your muscles — especially in your neck, shoulders, and upper back
- Heightens alertness and focus
- Diverts energy away from digestion, immunity, and repair
This is a genius system — when you’re in actual danger.
The problem? Today, your nervous system can’t tell the difference between a lion and a LinkedIn notification.
Why Modern Stress Is Different — And Why It’s Keeping You Stuck
In the past, stressors were acute — a threat would appear, your body would respond, and then it would resolve. The nervous system would switch off and return to baseline.
But in 2026? Many people are living in a state of chronic, low-level stress that never switches off.
Emails. Deadlines. Financial pressure. Family demands. News cycles. Phone notifications.
The result is that the sympathetic nervous system stays switched ON — and your body pays the price:
- Tight shoulders and upper back tension
- Chronic neck stiffness and restricted movement
- Tension headaches
- Lower back discomfort
- Difficulty sleeping and poor recovery
- Digestive issues
- Low energy and immune function
Your Spine & Nervous System — Why This Connection Matters
Here’s something that not enough people understand: your spine doesn’t just hold you upright. It protects your nervous system — the most important communication network in your entire body.
When your muscles stay partially contracted from chronic stress, that tension begins to affect how your spine moves. Restricted spinal movement means your nervous system isn’t getting the input it needs to function at its best.
Think of it this way: if your spine is a garden hose, stress-driven tension is like kinking that hose. The water still flows — but not as freely, and not as efficiently.
Sympathetic vs Parasympathetic — The Brake and the Accelerator
Your nervous system operates on a balance between two modes:
- Sympathetic Nervous System = the ACCELERATOR. This is fight or flight. It speeds everything up, contracts your muscles, and keeps you on high alert.
- Parasympathetic Nervous System = the BRAKE. This is rest, digest, and repair. It’s where healing happens, where sleep is deep, where recovery occurs.
Think of your body like a car. You cannot drive safely with your foot on the accelerator and the brake at the same time — and your body works the same way. These two systems operate on an ‘either/or’ basis. It’s one or the other.
The challenge is that so many people today are living life with the accelerator flat to the floor — 24 hours a day, 7 days a week — and never truly applying the brake.
The Vagus Nerve — Your Body’s Built-In Stress Reset
The vagus nerve is the longest cranial nerve in the body, running from your brainstem all the way down through your heart, lungs, and digestive system.
It’s the primary driver of the parasympathetic nervous system — your brake pedal. When the vagus nerve is functioning well, it helps:
- Slow your heart rate after stress
- Regulate digestion
- Reduce inflammation
- Promote deeper sleep and recovery
- Create a sense of calm and safety
When your nervous system is chronically stressed and your spine is restricted in movement, vagal tone can be reduced — meaning your body has a harder time shifting out of fight-or-flight and into rest-and-repair mode.
How Chiropractic Care at Family Chiropractic Chatswood Can Help
At Family Chiropractic Chatswood, when it comes to stress and the nervous system, we focus on two major things:
1. Restoring Movement to the Spine
Chiropractic adjustments help restore proper movement to spinal joints that have become restricted — often as a direct result of chronic muscular tension caused by stress. When your spine moves better, your nervous system communicates better.
2. Turning Down the Sympathetic Nervous System
Specific chiropractic care has been shown in research to help shift the nervous system out of sympathetic dominance and support better parasympathetic tone — in other words, helping your body find its brake pedal again.
This is not about chasing symptoms. This is about helping your body adapt better to the demands of modern life — so that when stress does come (and it will), your body is equipped to handle it and recover.
Don’t Wait for Pain to Be Your First Sign
One of the most important things I tell every patient: pain and inflammation are often late signs that something has been under strain for a while.
If you’re feeling the physical effects of stress — tightness, fatigue, poor sleep, recurring headaches — a spinal check can help you understand what’s going on and what steps to take next.
Your body is designed to heal, adapt, and function well. It just needs the right environment to do it.
After all, life is good when you are healthy and strong — but it becomes increasingly hard when you become stressed, sick, and run down. Chiropractic keeps you strong.

Frequently Asked Questions:
FAQ 1: Can a chiropractor help with stress and anxiety?
Yes — and here’s why. Chiropractic care doesn’t treat stress or anxiety directly as a psychological condition. What it does is address the physical impact that chronic stress has on your body, particularly your nervous system and spine.
When you’re under chronic stress, your sympathetic nervous system (fight or flight) stays activated, causing muscular tension — especially in the neck, shoulders, and upper back. Chiropractic adjustments help restore movement to restricted spinal joints, which can reduce muscular tension and support a shift toward parasympathetic (rest and repair) nervous system dominance.
Research has shown that chiropractic care may influence the autonomic nervous system, supporting better overall stress resilience. If you’re in Chatswood or Sydney and feeling the physical effects of stress, a Stress Less Assessment at Family Chiropractic Chatswood is a great starting point.
FAQ 2: What is the vagus nerve and what does it do?
The vagus nerve is the longest cranial nerve in the human body. It runs from your brainstem through your neck, chest, and all the way into your abdomen. It’s sometimes called the ‘wandering nerve’ because of how far it travels.
Its primary role is to activate the parasympathetic nervous system — often called the ‘rest and digest’ or ‘rest, digest, and repair’ system. When the vagus nerve is functioning well (known as good ‘vagal tone’), your body can:
- Slow the heart rate after stress
- Regulate digestion and gut function
- Reduce inflammation
- Promote deeper, more restorative sleep
- Create a sense of calm and safety in the body
In people with chronic stress, vagal tone can be reduced — meaning the body struggles to shift out of fight-or-flight mode. Chiropractic care, particularly work targeting the cervical spine (neck) and upper thoracic region, may support better vagal nerve function and parasympathetic tone.
FAQ 3: Why does stress cause neck pain and tight shoulders?
Stress causes neck pain and tight shoulders because of a direct physiological response from your nervous system. Here’s how it works:
When your brain perceives stress, it activates the sympathetic nervous system and triggers the release of stress hormones like cortisol and adrenaline. These hormones cause your muscles — particularly those in the neck, shoulders, jaw, and upper back — to contract and prepare for physical action (fighting or fleeing).
Under acute stress, this resolves quickly. But under chronic stress, these muscles remain partially contracted for extended periods. Over time, this sustained tension:
- Creates trigger points and knots in the muscles
- Restricts spinal joint movement in the neck and upper back
- Can lead to tension headaches
- Reduces blood flow and oxygen to the affected tissues
- Creates a cycle where the pain itself causes more stress
Chiropractic care addresses this cycle by restoring movement to restricted spinal segments, reducing muscular tension, and helping the nervous system shift out of stress mode — breaking the pain-stress feedback loop.
