Why Your Brain Loves Wood: The Neuroscience Behind Timber Interiors

A 2024 fMRI study by neuroscience research firm Neurensics — led by neurologist Prof. Dr. Steven Laureys and neuroeconomics specialist Dr. Steven Scholte — found that wood interiors measurably reduce stress and negative emotion, increase trust and calm, and activate the brain networks responsible for creativity and problem-solving, more than concrete or plastic interiors do. In short: wood doesn't just look good. It changes how your brain works.

For anyone choosing materials for a home, office, school, or clinic, that finding matters. Here's what the study actually measured, what it found, and what it means for the spaces you build or live in.

The Study, in Brief

The research was commissioned to scientifically test something designers have long claimed by instinct: that natural materials feel better than synthetic ones. Twenty-four participants lay inside an fMRI scanner while viewing 12 virtual interiors — living rooms, classrooms, hospital rooms, and offices — each rendered in one of three dominant materials: wood, concrete, or plastic. Researchers tracked brain activity and heart rate in real time, then had participants complete cognitive tasks to test creativity and problem-solving under each condition.

This wasn't a survey asking people what they thought they preferred. It was a direct read of what their brains actually did.

What the Brain Scans Showed

The results were consistent across every environment type:

• Wood increased positive emotion. Participants in wood-dominant spaces showed higher trust, calm, and a sense of connection.

• Concrete and plastic increased negative emotion. These materials more often triggered irritation, anger, and even aversion.

• Wood activated creativity and focus networks. Brain regions linked to creative thinking and sustained attention showed significantly higher activation in wood environments — and this carried through to better performance on the cognitive tasks that followed.

• Wood lowered physiological stress markers, including measurable effects on heart rate.

As Prof. Dr. Steven Laureys put it: "Natural materials have a positive impact on stress, focus, and cognitive performance."

How Wood Affects Different Spaces

The study broke results down by room type, and each one tells a slightly different story.

Offices — more trust, more creative output. Wood in a workplace is still somewhat unexpected, which may be exactly why it's so effective. Employees in wood-dominant offices showed higher trust and more flexible, creative thinking, and reported feeling safer and more productive — the difference between a space people merely occupy and one that actually generates ideas.

Classrooms — a familiar, home-like calm. The cognitive effect was less dramatic here than in offices or homes, but wood still reduced stress and helped students feel at ease, likely because it echoes the warmth of a home environment — a meaningful edge for concentration and learning.

Homes — better communication, more empathy. In living spaces, wood was linked to stronger social problem-solving. Residents in wood-rich homes reported feeling more heard and understood, and communicated more empathetically — turning a house from a place you live in into a place you live together.

Hospitals — less clinical stress, more connection. Sterile, cold materials in care settings often unconsciously trigger discomfort. Introducing wood measurably softened that response, increasing feelings of calm and connection — both important for patient recovery, even though wood is still rare in healthcare design.

Why This Matters When You're Building

Most material decisions in construction and interior design get made on looks, cost, or maintenance. This study adds a fourth, harder-to-ignore factor: how the material affects the people who'll spend years inside the building.

That's the principle behind engineered timber construction — using wood not as a decorative veneer, but as the structural and visual core of a space. At Artius, we build Glulam (glued laminated) timber homes, buildings, and solid wood window and door systems engineered specifically for Indian weather — so the same material the brain responds to positively also holds up to heat, humidity, and monsoon without warping or high maintenance.

Key Takeaways

• Wood interiors increase trust, calm, and positive emotion — and measurably reduce stress.

• Concrete and plastic interiors more often trigger irritation and aversion.

• Wood-dominant spaces activate brain networks tied to creativity, focus, and problem-solving.

• The effect holds across offices, classrooms, homes, and hospitals — settings with very different purposes.

• These aren't design opinions — they're findings from live fMRI brain scans.

Frequently Asked Questions

Does wood really affect brain activity, or is this just a design trend? The Neurensics study used fMRI scans — a direct measure of brain activity — not surveys or opinion polls. The differences in trust, stress, and creative-network activation between wood and non-wood environments were measured, not self-reported.

Is wood better than concrete for offices specifically? For measures of trust, creativity, and cognitive performance, yes — the study found wood-dominant offices outperformed concrete and plastic-dominant ones on all three.

Can engineered timber (like Glulam) provide the same benefits as solid wood? Engineered timber like Glulam is still wood — layered and bonded for strength and stability — so it retains wood's natural grain, texture, and visual warmth, the same qualities the study associated with positive brain response, while offering better structural performance and durability than traditional solid timber.

Who ran this study? It was conducted by Neurensics under the supervision of Prof. Dr. Steven Laureys, a neurologist and consciousness researcher, and Dr. Steven Scholte, a neuroeconomics specialist and CEO of Neurensics, on behalf of the wood industry federation Fedustria.

Building With What the Brain Actually Prefers

The takeaway isn't complicated: if you want a home, office, school, or clinic that people feel calmer, safer, and more creative in, wood isn't just an aesthetic choice — it's backed by how the brain physically responds to it.
