Direct Answer
Research consistently supports the developmental benefits of natural playgrounds. Key findings come from Richard Louv's work on "nature deficit disorder," Alan Sandseter's research on risky play, Bronfenbrenner's ecological systems theory, and the Reggio Emilia approach. The evidence shows that exposure to nature meets children's attentional and developmental needs, and that reconnecting with nature is both therapeutic and foundational.
Key Research and Researchers
Richard Louv: Nature Deficit Disorder
Foundational Text"Last Child in the Woods" (2005)
Richard Louv introduced the term "nature deficit disorder" to describe the human costs of alienation from nature. While not a medical diagnosis, the concept captures a real phenomenon with measurable effects.
Key Findings
- ADHD link: Lack of nature exposure is linked to ADHD-like symptoms—attention difficulties, hyperactivity, and impulsivity
- Attentional restoration: Exposure to nature meets children's attentional and developmental needs
- Therapeutic value: Reconnecting with nature is both therapeutic and foundational for healthy development
- Coherent understanding: Nature grounds children in an expansive, coherent understanding of the world
Alan Sandseter: Risky Play Research
Developmental ResearchNorwegian researcher Ellen Sandseter's work on risky play has been foundational in understanding why children seek challenge and how this benefits development.
Six Categories of Risky Play
- Play at height: Climbing, jumping, balancing on elevated surfaces
- Play at speed: Running fast, swinging, sliding, spinning
- Play with dangerous tools: Sticks, saws, screwdrivers, hammers
- Play near dangerous elements: Water, fire, heights
- Rough-and-tumble play: Wrestling, play fighting, chasing
- Play where children can disappear: Hiding, exploring out of sight
Urie Bronfenbrenner: Ecological Systems Theory
Theoretical FrameworkBronfenbrenner's ecological systems theory provides a framework for understanding how children develop within nested environmental contexts—from immediate settings (microsystem) to broader cultural influences (macrosystem).
Relevance to Playground Design
- Environment matters: Development happens in context, not in isolation
- Multiple influences: Family, community, culture all shape how children experience play
- Reciprocal relationships: Children shape their environments as environments shape them
- Holistic view: Cannot separate physical, social, and cultural aspects of environment
Reggio Emilia: Environment as Third Teacher
Educational PhilosophyThe Reggio Emilia approach, developed in Italy, introduced the concept of the environment as the "third teacher"—alongside parents and educators.
Key Principles
- Environment teaches: A well-designed space can adapt faster to children's developmental leaps than adults can through instruction alone
- Child as protagonist: Children are capable, curious, and full of potential
- Aesthetic matters: Beauty and order support learning and respect for children
- Responsive spaces: Environments should evolve with children's interests and development
How This Research Informs Design
These research foundations led to the development of Wearthy's Ecology of Play framework—a practical tool for ensuring playgrounds serve the whole child.
The Ecology of Play Framework
Developed to counter play bias and siloed thinking, this framework is inspired by Bronfenbrenner's ecological systems theory and Reggio Emilia's "environment as the third teacher."
- Child at the centre: Represented by a fingerprint—honouring uniqueness, agency, and reciprocal relationships with environment
- Children constantly evolve: Environments should keep pace with their development
- Environment as responsive teacher: Well-designed space adapts faster than instruction alone
- Icon-based toolset: Visual icons guide assessment, design, and continuous evolution
Research-Backed Design Principles
From this evidence base, several design principles emerge:
- Include nature: Not as decoration, but as integral to the play environment
- Allow appropriate risk: Challenge is essential, not something to eliminate
- Design for the whole child: Physical, social, emotional, cognitive, and spiritual
- Create responsive environments: Spaces that can evolve with children's development
- Consider context: Family, community, and cultural influences matter
- Avoid play bias: Don't overload one play type at the expense of others
- Honour children's agency: Design for children as capable protagonists

Key Takeaways
- Nature deficit disorder is real—lack of nature is linked to attention difficulties and ADHD-like symptoms
- Reconnecting with nature is therapeutic—and foundational for healthy development
- Risky play develops risk assessment—children need challenge to build judgement
- Environment is the third teacher—design matters as much as curriculum
- Ecological perspective is essential—children develop in context, not isolation
- Research supports natural playgrounds—the evidence base is strong and growing
