The surprising truth about stress, your child’s nervous system, and what to do next

As a parent, there’s nothing quite as heart-wrenching as watching your child unravel — melting down before school, struggling to fall asleep, panicking over seemingly small things, or withdrawing when the world feels too loud.

And if you’ve noticed that your child’s stress isn’t just emotional — but shows up in their digestion, immune function, focus, or mood — you’re not imagining it. You’re not overreacting. And you’re absolutely right to be concerned.

Stress is one of the most powerful forces acting on your child’s developing brain and body.

And yet — here’s what almost no one is telling you:

👉 Not all stress is bad.

Some types of stress are not only safe — they’re essential for healthy brain development and emotional resilience.

But there’s a fine line between stress that strengthens… and stress that derails your child’s nervous system entirely. And if your child is already showing signs of anxiety, ADHD, OCD, tics, or sensory issues — that line may already have been crossed.

Let’s unpack what’s really happening — and how to help.

Stress Isn’t Just an Emotion — It’s a Full-Body Neurological Event

Stress isn’t just “feeling overwhelmed.” 

It’s a biological chain reaction 
- one that starts in the brain and impacts every system in the body.

When your child perceives a challenge - whether it’s a new classroom, a loud noise, or even emotional tension at home - their Autonomic Nervous System kicks in. This system has two branches:

• The Sympathetic Nervous System - the “gas pedal” that triggers the fight-or-flight response

• The Parasympathetic Nervous System - the “brake pedal” that brings calm, rest, digestion, and regulation

A well-functioning nervous system can press the gas when needed — and then release it.

But in today’s world, most children are stuck with their foot slammed down on the gas.

Why? Because the balance is broken. And without enough Vagus nerve activation — the parasympathetic “brake” — their system can’t shift back into calm.

When Stress Becomes the Storm

A little stress — in the right dose — is like a workout for the nervous system.

It builds strength, flexibility, and resilience.

✅ Riding a bike for the first time

✅ Meeting a new friend at school

✅ Learning to navigate disappointment

✅ Problem-solving, exploring, growing…

These short bursts of “hormetic stress” activate the nervous system, then allow it to recover — and that builds stronger neural pathways, emotional regulation, and Vagus nerve function.

But that’s not the kind of stress most kids are facing today.

Instead, they’re up against:

🚨 Family instability

🚨 Academic pressure far beyond their developmental window

🚨 Sensory overload from screens and noise

🚨 Unresolved medical issues — gut, sleep, immune, allergies

🚨 Birth trauma, inflammation, chronic infections

🚨 Over-scheduling and zero downtime

When these stressors accumulate - from preconception through childhood - we call it The Perfect Storm (see more on this storm with our very own Dr Tony Ebel).

And the nervous system eventually short-circuits.

That’s when we start seeing real neurological symptoms:

Tics. Anxiety. Regression. Emotional outbursts. Sensory meltdowns. OCD. Sleep disturbances. Food intolerance. Constant illness.

Most systems call it a “disorder.”

We call it dysautonomia - a nervous system stuck in overdrive.

What Chronic Stress Looks Like in Real Life

Your child may not have the words to say, “Mum, I’m in sympathetic dominance and my Vagus nerve can’t kick in.”

But their body is speaking. Loudly.

Common physical signs:

• Trouble falling or staying asleep

• Constant tummy aches or erratic digestion

• Getting sick all the time

• Headaches or unexplained pains

• Irregular appetite or food aversions

Common behavioural signs:

• Mood swings or quick-to-anger

• Anxiety or panic about transitions

• Fear of separation or new situations

• Regression (clinginess, baby talk, bedwetting)

• Zoning out, poor focus, refusal to engage

• Withdrawing from things they used to love

These aren’t “bad behaviours.”

They’re the body’s distress signals — and they’re asking for help.

So How Do You Help a Child Stuck in Stress Mode?

The key is not to eliminate all stress (that’s impossible and unhelpful).

The goal is to restore nervous system balance — so your child can move through challenges with more ease and fewer symptoms.

At The Brain Health Movement, we support this in two ways:

1. Neurologically-Focused Care

This includes:

• INSiGHT Scans to assess Vagus nerve function and stress patterns

• Gentle, targeted neuro-adjustments to release subluxations

• Restoring the brain-body connection and parasympathetic tone

When this approach is done well, families often report:

• Better sleep, fewer infections

• Fewer meltdowns or shutdowns

• Improved focus and calm

• More resilience, curiosity, and connection

2. At-Home Nervous System Support

You can begin supporting your child right now through:

• Routine: predictable rhythms and gentle transitions

• Movement: jumping, swinging, crawling, climbing — all regulate the nervous system

• Nutrition: reduce inflammatory foods and hydrate well

• Nature time: lowers cortisol, raises oxytocin

• Downtime: quiet, unstructured space is not laziness — it’s therapy

Remember: the goal isn’t perfection. It’s capacity.

Final Word:

Your Child Isn’t Broken
- But Their Nervous System Might Be

Here’s the truth:

You don’t need more reward charts, discipline tactics, or surface-level strategies.

You need to understand what’s really going on in your child’s brain and body.

And you - the emotionally frayed, sleep-deprived, burnt-out one - need support too.

A dysregulated nervous system is not a life sentence.

With the right tools - and the right lens - healing is possible.

For them. For you. For the whole family.
