Neurosustainability: Designing Places Where Brains Can Thrive

Neuro-Sustainability: Designing Places Where Brains Can Thrive What if sustainability wasn’t only about carbon, materials, and energy — but also about the human brain? In this second episode of the mini-series about neuro-sustainability, neuroscience and architecture meet in a conversation that feels both urgent and surprisingly practical. We investigate the work of Cambridge scholarship student, Mohamed Hesham Khalil, which we believe should be integrated into planning and architecture around the world. “We can change diet, can change habits, but we cannot change a built environment. It’s built once and it lasts for tens of years.” Mohamed Hesham Khalil In this episode, he is joined by Burçin Ikiz, who brings a climate-and-health lens to brain wellbeing across the lifespan. Mohamed Hesham Khalil brings a design-and-research lens focused on environmental enrichment — and what our homes, streets, workplaces, and neighbourhoods are doing to us every day, whether we notice it or not. This is not a theoretical chat. It’s about how we design environments that help brains thrive — especially as heat, pollution, and chronic stress become part of daily life for millions. Why this episode about neuro-sustainability matters We like to think of brain health as something personal: sleep, diet, exercise, mindset. But the built environment is a long-term exposure — and it’s stubbornly permanent. If your surroundings make movement hard, keep you indoors, overwhelm your senses, trap heat, or load the air with pollution — you don’t just “feel it.” Your brain does too. What you’ll learn 1) What “environmental enrichment” means in the real world This conversation translates neuroscience into design language: environments that support movement, stimulation, connection, and recovery. “Don’t use it, you lose it. Just kind of like our muscles in our bodies.” Burçin Ikiz 2) The indoor reality we rarely talk about If buildings are designed mainly for convenience and comfort, what happens to stimulation, mobility, and everyday brain engagement? “When we spend like around 90 percent of time indoors… almost no chance for cognitive stimulation or physical activity through the building…” Mohamed Hesham Khalil 3) Heat, buildings, and brain function As the climate warms, poorly adapted buildings become neurological stressors — not just uncomfortable boxes. “If most of our buildings… have not been created for this increasingly warming world, it can be very, very hot indoors and that can really affect our brains.” Burçin Iki...
