Your surroundings affect your wellbeing because the nervous system responds to environmental cues before the brain consciously processes them. Elements such as light, noise, colour, spatial layout, and visual clutter can either support nervous system regulation or increase stress. Supportive environments help the body feel safe and calm, while chaotic or overstimulating spaces can trigger stress responses like fight, flight, freeze, or overwhelm.

Research in environmental psychology and neuroaesthetics shows that factors such as natural light, reduced clutter, calming colours, and access to nature can significantly improve mental wellbeing, focus, and emotional 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.

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.
