One in seven people worldwide is neurodivergent. For many — particularly those with autism spectrum disorder, ADHD, or sensory processing differences — the built environment is not neutral. It is an active source of input: fluorescent lights that flicker at frequencies most people don’t consciously register, hard surfaces that bounce sound into a wall of noise, synthetic materials that offer no tactile variation, and spaces that provide no refuge from the accumulation of it all.
Sensory rooms have emerged as one of the most evidence-supported responses to this reality — spaces specifically designed to help individuals regulate their nervous systems through controlled sensory input. But a quieter, less widely discussed body of research points to something that doesn’t require a dedicated room at all: the presence of nature.
The growing intersection of biophilic design and neurodivergent-inclusive spaces is one of the most compelling developments in environmental design today. And the evidence behind it deserves a closer look.
What sensory rooms are — and what the research shows
Sensory rooms — also called multi-sensory environments (MSEs) or Snoezelen rooms — are purpose-built spaces that provide controlled sensory stimulation to help individuals regulate their nervous systems. They typically incorporate adjustable lighting, tactile surfaces, sound elements, and movement equipment, all calibrated to either calm an overstimulated nervous system or engage an understimulated one.
The research on their efficacy is substantial. A 10-year retrospective study published in Cureus (2024) followed 548 children with autism spectrum disorder and found that combining sensory room therapy with conventional therapy produced significantly better outcomes than conventional therapy alone — including improvements in sensory processing, motor skills, and engagement in daily activities.
A 2025 systematic review published in Frontiers in Pediatrics analyzed 21 studies on sensory-based interventions for children and youth published between 2015 and 2024, finding consistent evidence of functional improvements across a range of sensory and developmental conditions. A 2025 study in Pediatric Reports examining sensorimotor room training in children ages 2–10 with ASD found measurable improvements in both sensory and motor skill development across all severity levels.
The evidence is clear: intentional sensory environments work. The more interesting question is why — and what role nature plays in that.
The nervous system and nature: a deeper connection
Humans evolved in natural environments. Our nervous systems developed in relationship with the sensory qualities of the natural world — organic light that shifts throughout the day, sounds that vary without harshness, textures that differ without demanding conscious attention, and visual complexity that the eye can rest on without effort. These qualities are what researchers call “restorative” — they engage the nervous system gently, without triggering the stress response that hard-edged, synthetic, or unpredictable environments can provoke. Our article on biophilia and healing explores the broader research on nature’s role in mental health and trauma recovery.
For neurodivergent individuals, this distinction is particularly significant. A 2026 systematic review published in Architecture (MDPI) found that the deliberate integration of natural elements and biophilic design strategies supports stress reduction and emotional regulation in children with neurodevelopmental differences — with biophilic design functioning as an environmental strategy and emotional regulation as a measurable cognitive outcome. The review noted that structured exposure to nature reduces repetitive behaviors and supports social interaction in children with ASD, and that the effects vary based on the type and level of sensory exposure.
A scoping review published in the Review Journal of Autism and Developmental Disorders (2024) found consistent evidence that biophilic learning environments — incorporating natural patterns, water elements, natural sounds, and daylight — benefit children with autism. The review’s recommendations align closely with what the sensory room research also supports: controlled, varied, non-overwhelming sensory input that the individual can engage with at their own pace.
What biophilic elements specifically offer neurodivergent individuals
The overlap between effective sensory room design and biophilic design principles is not coincidental. Both share a core logic: the nervous system responds to the qualities of its environment, and those qualities can be intentionally shaped to support regulation rather than dysregulation.
Living plants offer several specific qualities that are particularly relevant for neurodivergent individuals. Their visual complexity — the irregular patterns of leaves, the variation in color and texture, the subtle movement in air currents — provides what researchers describe as “soft fascination”: sensory engagement that holds attention without demanding cognitive effort. Unlike screens or mechanical stimuli, plants don’t trigger alerting responses. They invite the nervous system to settle. The psychological benefits of plants extend to focus, mood, and emotional regulation — benefits documented across both clinical and workplace settings.
These effects are particularly well-documented in children. Our article on how interior landscaping aids child development covers the research on nature’s impact on sensory experience, attention, and emotional regulation in young people — including neurodivergent children in school and healthcare settings. The nature and adolescent mental health research extends these findings into the teenage years, a period when sensory and emotional regulation challenges often intensify.
Moss walls and preserved botanical installations offer tactile variation — surfaces that feel different from the hard, uniform materials that dominate most commercial and institutional interiors. For individuals who seek proprioceptive grounding or who are calmed by textural engagement, the organic irregularity of natural materials can provide meaningful sensory input without the unpredictability that often triggers dysregulation.
Natural elements also address acoustics. As we explore in our article on MossWallArt™ and acoustic absorption, preserved moss has Noise Reduction Coefficient (NRC) values ranging from 0.55 to 0.90 — significantly higher than bare drywall at approximately 0.05. For individuals with auditory hypersensitivity, reducing ambient echo and noise reverberation through natural materials is a meaningful environmental intervention.
The emerging field of neuroinclusive biophilic design
The design world is beginning to formalize this connection. Metropolis Magazine’s 2026 Neuroinclusive Design Product Guide explicitly lists biophilia as one of five core principles for designing inclusive environments — alongside acoustics, calibration, personalization, and compartmentalization. The guide notes that biophilic elements can reduce sensory overload by softening visual complexity and lowering physiological stress.
This represents a meaningful shift. Biophilic design has long been understood as beneficial for neurotypical well-being — reducing stress, improving focus, and elevating mood. Its application to neurodivergent-inclusive design is newer, but the underlying mechanisms are the same. The nervous system’s response to natural environments doesn’t change based on neurotype; what changes is how acutely that response is needed.
For architects, interior designers, school administrators, and facility managers designing spaces for neurodivergent individuals, this research opens a practical question: what natural elements can be integrated into existing environments — not just dedicated sensory rooms — to support regulation throughout the day? Living plant installations, moss walls, natural materials, and considered use of natural light all represent accessible, scalable interventions that don’t require a separate room.
A note on what this means for interior landscapes
Plant Solutions designs interior landscapes for commercial, institutional, and residential spaces across the Phoenix metro area. While our work is not therapeutic in a clinical sense, the research on biophilic design and sensory regulation is directly relevant to how we think about the spaces we design — and to the clients who ask us to consider not just aesthetics, but how a space will feel for the full range of people who use it. Our article on horticultural therapy and nature-inspired spaces explores how plant-based environments support well-being in therapeutic and community settings. For organizations focused on wellness in the workplace, biophilic design offers a tangible, research-backed path to more inclusive, supportive environments.
If you are designing or refreshing a space with neurodivergent users in mind — a school, a healthcare facility, a workplace, or a residential environment — we welcome the conversation. Contact Plant Solutions to discuss how biophilic elements might support your design goals.
FAQ:
Does biophilic design help neurodivergent individuals?
Yes — and the research is growing. Multiple peer-reviewed studies have found that natural elements in built environments reduce stress, support emotional regulation, and lower sensory overload in individuals with autism spectrum disorder, ADHD, and sensory processing differences. The mechanisms are well understood: natural environments provide sensory input that the nervous system finds restorative rather than alerting, which is particularly meaningful for individuals whose nervous systems are more sensitive to environmental stimuli.
Can plants reduce sensory overload?
Plants and natural materials can meaningfully reduce two of the most common contributors to sensory overload in built environments: visual harshness and acoustic reverberation. The irregular, organic visual complexity of living plants provides what researchers call “soft fascination” — engagement that calms rather than overstimulates. Preserved moss walls have documented Noise Reduction Coefficient (NRC) values of 0.55 to 0.90, making them a measurable acoustic intervention in spaces where hard surfaces amplify sound.
What natural elements work best in sensory-supportive spaces?
The most effective natural elements for sensory-supportive environments tend to be those that offer controlled, predictable sensory input: living plants with soft, varied foliage; preserved moss walls that provide tactile variation and acoustic absorption; natural light that shifts gradually rather than flickering; and organic materials like wood and stone that offer textural variety without overwhelming pattern. The key is variation without unpredictability — which is precisely what natural elements provide and most synthetic materials do not.
Is a sensory room required to get the benefits of biophilic design for neurodivergent users?
No. Dedicated sensory rooms are valuable, but the research suggests that biophilic elements distributed throughout an environment — in hallways, classrooms, waiting areas, and common spaces — can support regulation throughout the day rather than only during designated sensory breaks. Even modest interventions, such as a plant wall in a reception area or natural materials in a therapy room, can shift the sensory quality of a space in ways that benefit neurodivergent users.
How does biophilic design relate to WELL and LEED building certification?
Both the WELL Building Standard and LEED certification frameworks include biophilic design elements as contributors to occupant health and well-being. WELL’s Mind and Community concepts specifically address sensory comfort, stress reduction, and access to nature as measurable building performance criteria. For organizations pursuing certification, integrating living plant installations, moss walls, and natural materials serves both the certification goals and the practical well-being needs of neurodivergent building users.
