All In The Mind
Intuitively we sense that nature relaxes us -- even small pockets of green in the concrete urban jungle seem to make a difference. But finding good scientific evidence for how and why has been more difficult -- until now. Crime rates, academic performance, aggression and even ADHD. Could a bit of greening make all the difference? And, ecology on the couch -- a self described 'ecotherapist' with novel techniques.

Greening the Psyche: How Trees, Gardens and Parks Shape Our Minds
Episode Overview
- Research in Chicago public housing suggests that, after controlling for key variables, buildings with more trees have noticeably lower crime rates.
- Exposure to nature appears to restore attention and improve impulse control, with studies showing benefits for children with ADHD after time in greener settings.
- Green school playgrounds are linked to children feeling more mentally restored after play, which correlates with stronger attention and better academic performance.
- Community gardens offer calm, creativity and social connection, giving adults and children alike a place to de-stress and feel part of something living.
- Ecotherapy uses gardening and natural metaphors to help people express emotions and rebuild a sense of growth and possibility in their lives.
“Even something that could appear to be dead still has within it enough energy to spring alive again.”
How do people find calm, focus and even a sense of safety just by being around a few trees or a patch of grass? This episode of All In The Mind looks straight at that question, asking what green spaces might be doing to the human mind. Host Natasha Mitchell brings together researchers, gardeners and an ecotherapist to ask whether "a bit of urban greening" could affect crime, mental health and even ADHD.
Environmental psychologist Professor Frances Kuo shares years of research from Chicago public housing, where identical buildings differed mainly in the amount of vegetation around them. Her headline finding is simple and striking: "The more trees, the fewer crimes." She explains how nature seems to calm people and restore impulse control, offering a low-cost addition to traditional crime and health strategies.
Artist Nancy Layett and gardener Cathy add lived experience from a Melbourne community garden, talking about creative blocks easing and stress dropping away as they walk among vegetables and flowers. One child simply loves to "climb up the trees", hinting at how instinctive this pull to nature can feel. UK-based ecotherapist Amber Burles takes things further, using gardens as part of therapy for people with serious mental health problems.
She describes powerful moments where plants become mirrors for human experience, like a client who uprooted a shrub because she "felt just like that bush" – then replanted it as a symbol of her own hoped-for recovery.
For Amber, the image of a seemingly dead tree trunk sprouting green shoots says it all: "Even something that could appear to be dead still has within it enough energy to spring alive again." Rounding things off, researcher Kathleen Baggett shows how greener school playgrounds are linked to better attention and, in turn, stronger academic performance.
If a few trees, gardens or pockets of grass can shift behaviour, focus and mood, what might happen if cities treated green space as essential, not a luxury?
