Nervous System Explained: A Beginner’s Guide to Stress, the Vagus Nerve and Regulation
I hear this all the time from people I work with:
"I keep hearing about nervous system regulation… but I don’t actually understand what it means."
Maybe you’ve heard the phrases too:
regulate your nervous system
fight or flight
somatic practices
trauma-informed wellbeing
vagus nerve activation
But no one has ever really explained what the nervous system actually is, or why it matters so much for stress, burnout, and emotional wellbeing.
So this is a very simple guide.
No medical jargon.
No complicated biology.
Just the basics of how your body and mind work together to keep you safe.
Nervous System Regulation Explained: A Beginner’s Guide to Stress, Safety and Wellbeing
So many people ask me to explain to them what the Nervous System is, like as if they know nothing - a “nervous system for dummies” explanation.
I think it’s shocking that this isn’t taught to young kids in school, to doctors, mental health practitioners, and really anyone interacting with… I dunno - other humans!?
It’s basic human life, and we don’t know about it, no wonder so many of us are crumbling - we’re simply not equipped to know how to manage ourselves, interpret our own behaviours and translate anyone around us.
We talk a lot about stress.
Stress at work.
Stress in leadership.
Stress in relationships.
Stress in modern life.
But very rarely do we talk about the system in the body that is actually processing all of that stress in the first place.
Why I hate the phrase “My anxiety”.
I hate the phrase “my anxiety”.
Because when we say it like that, it makes it feel like anxiety is part of us.
Something we own.
Something we’re stuck with.
It makes it our identity.
And here’s the truth:
You are not anxiety.
Anxiety is not you.
For too long, anxiety has been framed as a mental health diagnosis. And while therapy, meditation, and medication can help with the racing thoughts, the fear, and the worry - too often, we forget the body behind the feelings.
