Your Nervous System Isn't the Problem — It's Trying to Protect You

Wellwise OT | Integrative Health and Wellbeing

Can I let you in on something that changes the way a lot of my clients see themselves?

Most people come to me carrying a quiet belief that something is wrong with them. That they're too anxious, too shut down, too reactive, too sensitive, too stuck. That they should be able to just get on with things — but can't.

What I want you to know is this: your nervous system is not broken. It is doing exactly what it was designed to do. And once we understand that, everything starts to shift.

What is Polyvagal Theory?

Polyvagal Theory was developed by neuroscientist Stephen Porges, and it's one of the frameworks I draw on most in my practice at Wellwise OT. In simple terms, it's a map of how your autonomic nervous system — the part of you that runs beneath conscious thought — responds to the world around you.

At its heart, polyvagal theory is a science of safety. Porges describes how our nervous systems are constantly — and automatically — scanning our environment for cues of safety or danger. He calls this process neuroception. It happens without your awareness, without your permission, and without your conscious mind being involved at all. Your body is always asking: Am I safe here? Can I connect? Do I need to protect myself?

Depending on the answer, your nervous system shifts into one of three states:

Ventral Vagal — Safe and Connected

This is the state where life happens. You feel calm, present, and able to engage. You can connect with others, think clearly, be curious, be creative. You can do the things that matter to you. This is where healing happens too.

Sympathetic — Fight or Flight

When your nervous system detects a threat — real or perceived — it mobilises you for action. Your heart rate rises, your muscles prepare, your focus narrows. This shows up as anxiety, irritability, overwhelm, restlessness, or that feeling of being constantly "on."

Dorsal Vagal — Shutdown and Freeze

When the threat feels too great, the nervous system's oldest survival response kicks in — it shuts down. This can look like numbness, dissociation, exhaustion, depression, or a deep flatness. It's not weakness. It's protection.

Why Does This Matter for Your Daily Life?

Here's the thing that I find so powerful about this framework: it makes sense of so much.

When you can't get off the couch, it might not be laziness — it could be a shutdown response. When you snap at the people you love, it might not be a character flaw — it could be a sympathetic nervous system in survival mode. When you feel disconnected from things you used to enjoy, it might not be that you've lost who you are — it might be that your nervous system doesn't yet feel safe enough to let you back in.

Life works in seasons. And sometimes the seasons we go through — trauma, loss, chronic stress, illness, burnout — train our nervous systems to stay on guard even when the danger has passed. The body keeps the score, as Bessel van der Kolk so aptly put it.

Healing isn't linear. But understanding your nervous system is often where it begins.

How I Bring This into Occupational Therapy Practice

As an occupational therapist, I'm always thinking about your life as it's actually lived — the things you do, the roles you hold, the occupations that give you meaning and structure. And polyvagal theory fits beautifully within that lens, because you simply cannot engage meaningfully with your life when your nervous system is in survival mode.

You can't parent the way you want to when you're in fight-or-flight. You can't create, connect, or contribute when you're shut down. The occupations that matter most to you — they live in the ventral vagal state. So that's what we work towards, together.

Here's how that looks in practice:

Understanding your nervous system

One of the first things I do with clients is help them understand this map. When you can name what state you're in — "I'm in shutdown right now" rather than "I'm worthless and can't do anything" — it changes your relationship with yourself. There's so much less shame in understanding that your body is responding, not failing.

Co-regulation in sessions

You don't regulate alone — and you were never meant to. Research shows that our nervous systems are fundamentally social, designed to find safety in connection with others. In sessions, I'm mindful of how my own presence, tone, pace, and energy contribute to whether you feel safe enough to explore difficult things. This is called co-regulation, and it's foundational to the work. As the research tells us, co-regulation always comes first — and through that, self-regulation gradually becomes possible.

Sensory-based regulation strategies

The body is the way in. Because neuroception operates below conscious thought, we often can't think our way into a regulated state — we have to move our way there. Breath work, movement, rhythm, texture, sound, nature, warmth — these aren't just nice ideas. They are physiological tools that communicate safety to your nervous system. I help clients identify the specific sensory strategies that work for their nervous system — because what regulates one person may overwhelm another.

Connecting regulation to occupation

This is where the occupational therapy difference really comes alive. Once we start to understand your nervous system and build your regulation toolkit, we bring it back to your daily life. What does your morning routine look like when your nervous system feels safe? What occupations help you shift states — from shutdown into gentle movement, from overwhelm into calm? How do we design your days, your environment, and your habits in a way that supports your nervous system rather than constantly activating it?

A Note on Safety and Complexity

It's worth saying: polyvagal theory is a framework, not a prescription. It's a map, and maps are useful — but they're not the whole territory.

Some of my clients have nervous systems shaped by years of trauma, chronic pain, or significant mental health challenges. The work is careful, paced, and always done with your wellbeing at the centre. I always work alongside other health professionals when needed, and I encourage you to seek integrated support rather than seeing any one approach as the whole answer.

Be kind to yourself as you learn about your nervous system. It has been working hard, for a long time, to keep you safe. That's not something to fight. It's something to understand, gently — and slowly, to befriend.

You Are an Occupational Being with a Nervous System

We are occupational beings. We are also nervous system beings. And the two are inseparable.

When your nervous system finds safety, your life opens up. The things you want to do — the roles, the relationships, the creativity, the daily rhythms — they become possible again. Not all at once. Not in a straight line. But bit by bit, season by season.

That's the work I'm here for.

If you're curious about whether this approach might be right for you, I'd love to have a conversation.
