Cortisol, calm and colour
The spaces we inhabit directly influence how we feel. Every day.
The room you wake up in shapes your mood before you've begun your day. The corner you settle into after work either helps you decompress or quietly keeps you wired. The environment you create at home influences your energy levels, your creativity, your mood, even how clearly you think.
This isn't soft wellness talk. Researchers have found that our surroundings affect cortisol levels, cognitive function and emotional regulation — they are either helping us feel better or worse.
In this guide we explore five elements that determine how a room feels — and how to use them to create a space that genuinely restores you.
It's Called Neuroaesthetics (Stay With Me)
Neuroaesthetics is the study of how our brains respond to beauty — why certain spaces, objects, and images feel instinctively right. Studies have shown that when we perceive something beautiful, the brain's pleasure and reward centres become measurably more active. In plain English: beauty isn't indulgent. It's neurological.
A well-considered space doesn't just look good. It actively shifts how you feel, think, and how your body and mind restore after a busy day. Which means that art print you've been deliberating over for six months? Medically defensible. You're welcome.
Here are five elements that quietly govern how a room makes you feel — made simple.
1. Colour: Give Your Brain Somewhere to Land
We've all lived through the magnolia years. Every wall, every ceiling, every skirting board. Your brain wasn't resting — it was bored senseless.
There's a reason so many interiors default to white — the brain reads it as neutral, restful. But here's the thing: a totally white room can actually feel unfinished. Your brain keeps searching for something to settle on, like a paragraph with no full stop.
Introduce even the subtlest colour — a warm wall, a beautifully layered painting, a stack of linen cushions in dusty sage — and suddenly the room has a resting point. The brain relaxes because it has arrived somewhere that feels complete.
Colour also speaks in emotion: soft blue calms, warm yellow energises, terracotta grounds, deep green restores. None of this needs to be heavy-handed. A single expressive artwork in a relatively neutral room can be enough — we don't have to overwhelm a room with colour, often less is more.
2. Texture: The Fastest Route to Relaxation
We are sensory creatures, and texture is the element most people underestimate. A room without texture feels cold no matter what the thermostat says.
Think linen, rattan, raw wood, a sheepskin draped over a chair, a silk cushion catching the light. The more natural the material, the more the nervous system responds — that sheepskin thrown over a chair is doing more for your nervous system than a week of inbox zero.
Layering textures is the difference between a room that's been decorated and a room that's been lived in — a room that's nice to look at and one you want to cosy down in.
3. Light: Your Room's Most Underused Design Tool
Natural light is wonderful. But once the sun sets there is an opportunity to create a whole new atmosphere. The rooms that truly restore you tend to be shaped by secondary light — lamps, dimmable pendants, a candle on a side table. These softer, lower sources create an atmosphere that overhead lighting simply cannot.
And here's something few people consider: a layered original painting reveals itself differently throughout the day. Morning light catches the raised texture of brushwork; a downlighter at evening casts gentle shadow across it. The painting you bought isn't one painting — it's several, depending on the hour. That's depth and intrigue you won't get from a blank wall.
4. Collected Objects: The Antidote to Show-Home Syndrome
Family photographs. A bowl brought back from a market in Marrakech. Books with broken spines. Objects that don't match but somehow belong.
That market find you nearly didn't buy because 'where would it even go' — it's carrying the whole room. The matching cushion set is decorative. The bowl has a story.
This is what separates a room that looks beautiful in a magazine but feels oddly hollow in person, from one that feels genuinely warm the moment you walk in. Meaning is the missing ingredient in most interiors. You can't buy it as a set — it accumulates.
5. Fragrance: The Sense Everyone Forgets
You know that feeling when a scent hits you and you're instantly somewhere else — a holiday, a person, a moment you'd half forgotten? That's not coincidence. Scent is the fastest route to memory and mood we have. Use it.
You don't need anything that takes you straight back to Afflecks Palace circa 1995 — all patchouli and tie-dye. Natural essential oils, a beautiful resin incense, or a room mist with notes of cedar, neroli, or oud can shift the entire sensory register of a space in seconds. Choose natural over synthetic where you can — not just for the experience, but because synthetic fragrance compounds have increasingly been linked to poor air quality and can affect pets more than we realise.
One Last Thing: Permission to Mix
The most beautiful rooms are rarely the most coordinated ones. They have a temperature — a consistent emotional register — rather than a matching scheme.
A calm living room uses colours that soothe, textures that invite you to sit down and stay, pieces that carry meaning. It doesn't matter if the lamp is from a flea market and the art is an investment piece. It mixes old with new, pattern with plain. What matters is that nothing fights.
The spaces that truly restore us aren't designed — they're gathered. Piece by piece, trip by trip, with the things that made your heart do a little leap before your brain had a chance to ask where they'd go. That painting you fell for. The textile you couldn't leave behind. The scent that takes you back to an exotic trip. The bowl that has absolutely no business being as perfect as it is in that corner…go for it! Your cortisol levels will thank you.
