The research is clear: time in nature, relationships with animals, and a sense of belonging to the planet are not luxuries for children. They are necessities.
There is something instinctive about the way a child reacts to a dog bounding towards them, or the way a toddler stops everything to crouch down and study an ant on the pavement. Before we teach children about nature, they already seem drawn to it — fascinated by it, comforted by it, alive within it. This is not coincidence. It is biology.
In a world where screens increasingly compete for children's attention and urban environments replace green spaces, the question of how connected our children feel to the natural world has never been more important. And the science backing up what many parents instinctively feel — that nature matters deeply for their child's wellbeing — is both compelling and growing.
The biophilia hypothesis: we are wired for nature
In 1984, biologist Edward O. Wilson introduced the concept of biophilia — the idea that human beings have an innate, evolutionary tendency to seek connection with other living systems. We didn't just evolve alongside nature; we evolved as part of it. For hundreds of thousands of years, our survival depended on understanding, respecting and living within the natural world.
Children, Wilson argued, are especially sensitive to this pull. Their developing brains are in a critical window of formation, and exposure to natural environments during this period shapes not just their relationship with the planet, but their cognitive, emotional and social development in profound ways.
Decades of research since Wilson's original work have built a formidable body of evidence supporting this idea.
Nature and mental health: the evidence
A landmark study published in the Proceedings of the National Academy of Sciences found that people who walked in natural environments showed significantly lower activity in the part of the brain associated with rumination — the repetitive negative thinking linked to depression and anxiety. In children, who are increasingly experiencing mental health challenges at younger ages, this finding is particularly significant.
A large-scale review published in the International Journal of Environmental Research and Public Health, analysing data from over 100 studies, concluded that exposure to green spaces was consistently associated with reduced symptoms of anxiety, depression and attention disorders in children and adolescents. The effect was dose-dependent — the more time spent in nature, the greater the benefit.
Richard Louv, author of the influential book Last Child in the Woods, coined the term "nature deficit disorder" to describe the growing disconnection between children and the natural world, and the behavioural and psychological consequences that follow. While not a clinical diagnosis, the concept has resonated deeply with researchers, educators and parents alike, and has inspired a global movement to bring children back outdoors.
Attention, focus and academic performance
One of the most consistent findings in environmental psychology is the effect of nature on children's ability to focus. Attention Restoration Theory, developed by psychologists Rachel and Stephen Kaplan, proposes that natural environments restore our capacity for directed attention — the kind of focused, effortful thinking required for learning — in ways that built environments simply cannot.
A study conducted by the University of Illinois found that children with ADHD showed significantly improved concentration after just 20 minutes of walking in a park, compared to the same walk in an urban setting. Other research has demonstrated that schools with access to green schoolyards and nature-based learning environments see improvements in academic engagement, classroom behaviour and overall academic performance.
Simply put, nature gives children's brains room to breathe — and when they return to structured learning, they do so with greater capacity and focus.
The profound role of animals
The relationship between children and animals deserves its own chapter in the story of childhood development. Across cultures and throughout history, children have formed bonds with animals — and science tells us these bonds are far more than sentimental.
Research published in the journal Anthrozoös found that children who had meaningful relationships with animals demonstrated higher levels of empathy, both towards other animals and towards other people. The act of caring for another living creature — understanding its needs, responding to its emotions, being responsible for its wellbeing — appears to build the very foundations of compassionate human relationships.
Animal-assisted therapy has been shown to reduce cortisol levels (the stress hormone) in children, improve social interaction in children with autism spectrum disorder, and provide emotional regulation support for children who have experienced trauma. Even simply being in the presence of a calm animal has measurable physiological effects — lowering heart rate and blood pressure, and activating the parasympathetic nervous system that governs rest and recovery.
But the benefits don't require a formal therapeutic setting. A child who grows up with a family pet, who visits a farm, who watches birds in the garden or who learns to be gentle with a creature smaller than themselves is quietly developing a richer emotional life, a broader sense of empathy, and a deeper understanding of the interconnectedness of living things.
Belonging to something bigger: ecological identity
Beyond the immediate psychological benefits, researchers have begun exploring what they call ecological identity — a child's sense of themselves as part of the natural world rather than separate from it. This sense of belonging, of being one species among many sharing a living planet, has been linked to greater environmental stewardship in adulthood, higher levels of meaning and purpose, and stronger overall psychological resilience.
A study published in Environment and Behavior found that children who spent meaningful time in nature during childhood were significantly more likely to become environmentally conscious adults — not because they were lectured about climate change, but because they had formed an emotional bond with the natural world that they felt motivated to protect.
This is perhaps the most quietly powerful argument for prioritising children's connection to nature. We cannot expect the next generation to care for a planet they have never truly known. But children who have felt the texture of bark under their fingers, who have watched a caterpillar become a butterfly, who have felt the particular peace of sitting beside water — these children carry something within them that no classroom lesson can fully replicate.
What parents can do
The good news is that fostering a child's connection to nature does not require grand gestures or wilderness expeditions. Research consistently shows that even small, regular doses of nature have meaningful effects.
Some of the most impactful things parents can do include making unstructured outdoor time a daily priority, even if it is just a garden or a local park. Allowing children to get dirty, to explore, to turn over rocks and follow insects without a predetermined outcome. Introducing children to animals — whether a family pet, a visit to a farm, or simply feeding birds in the garden. Naming the plants and creatures in your local environment, building a sense of familiarity and relationship with the natural world on your doorstep. And perhaps most importantly, being present in nature alongside your children rather than simply sending them out — your own sense of wonder is contagious.
A final thought
At Terraseed, our belief in nurturing children goes beyond what we put into our supplements. It extends to how we think about childhood itself — as a time that should be rich with sensory experience, wonder, relationships and rootedness. A child who feels connected to the natural world is not just happier and healthier today. They are more empathetic, more focused, more resilient, and more likely to grow into an adult who contributes meaningfully to the world around them.
Nature is not a backdrop to childhood. For children, it is — quite literally — where they come alive.
At Terraseed, we believe in supporting children from the inside out. Explore our Vegan Kids Gummies, formulated to complement a healthy, active and nature-connected childhood.
