RESEARCH UPDATE: March 19, 2026
For years, we at The Fat Plant Society have championed the visual connection to nature as a tool for calm.
But as we move through 2026, the data has evolved from ‘suggestive’ to ‘conclusive.’ Recent neuropsychological studies –including 2025 breakthroughs in brain plasticity reveal that biophilic interventions (of which moss walls are a core element) aren’t just pleasant to look at, they actively reduce cortical load and may help stabilize neuropathways in aging brains.
In this updated guide, we share the research that confirms biophilic design is essential for memory care. We’ll also explore how moss walls and designs are transitioning from design ‘extras’ to vital, non-pharmacological components of memory care therapy.
Once again, the answer lies in NATURE.
If you find yourself reading this article, we probably don’t need to review the concept of biophilic design or the 14 Patterns of Biophilic Design set forth by the brilliant minds at Terrapin Bright Green.
This article stems from years of research, first-hand monitoring of senior living environments, and careful notations regarding the challenges architects, developers, staff, and residents face in balancing a multitude of needs, including memory care.
Those needs range from sustainable building materials (for cost savings as well as green building) to wipeable and hygienic surfaces to effectively managing the workload of staff and caregivers.
Last, but certainly not least, is the well-being of senior residents. Architecture, building design, and interior design play a crucial role not only in an individual’s overall perceptions of wellness but also in slowing memory decline, reducing anxiety, and improving mood.

The Nature-First Revolution: How ‘Biophilic’ Memory Care is Rewriting the Rules of Aging
For decades, memory care environments were designed with a single priority: safety. The resulting facilities were often functional but sterile—characterized by locked doors, artificial lighting, and long, disorienting corridors. The visual environment was prioritized for surveillance, not stimulation.
However, a groundbreaking paradigm shift is underway, driven by research from 2024 through 2026.
This new approach, known as Nature-Supported Memory Care, posits that a constant visual and physical connection to the natural world is not just a “nice-to-have” amenity, but a powerful, non-pharmacological intervention that may actively slow the progression of memory loss and cognitive decline.

The Science Behind the Scenery
New evidence published in prominent journals Frontiers in Psychology and MDPI suggests that biophilic design—the deliberate integration of natural elements into the built environment—can have measurable effects on brain function, specifically for seniors living with dementia and Alzheimer’s.
1. Slowing Cognitive Decline Through Reduced ‘Cognitive Load’
Research indicates that older adults rely heavily on visual cues for orientation. Institutional environments, lacking distinctive natural landmarks, often require excessive cognitive effort simply to navigate, leading to cognitive fatigue and accelerated decline. Conversely, a 2024 review found that visual environmental stimulation rich in natural cues helps maintain attention and processing speed—effectively grounding residents in their surroundings without overloading their diminishing neural capacity.

2. Reactivating Long-Term Memories
Dementia typically erodes recent memories first, leaving long-term memories intact longer. Nature has a unique ability to act as a sensory key to these distant pathways. The smell of rosemary, the sound of falling water, or the sight of changing seasons can trigger memories of childhood homes or familiar outdoor activities. New neurological research from 2025 supports the idea that interactions with nature may enhance brain plasticity in areas critical for memory and emotional regulation.

3. Stabilizing Mood and Reducing Agitation
The reduction of stress is perhaps the most immediate benefit of nature-supported care. Studies show that natural views facilitate faster recovery from physiological stress. This is critical for memory care, as chronic stress and agitation often lead to behavioral symptoms (known as “sundowning”) that facilities frequently manage with antipsychotic medications. By integrating nature, facilities are reducing the pharmacological burden on their residents.

Case Studies: Implementation in Practice
Two facilities leading the way in operationalizing this research are The Cordwainer in the United States and Tune Nursing Home in Denmark.
The Cordwainer (Norwell, MA):
Year-Round Biophilic Immersion
The Cordwainer is a premier example of constant visual connection to nature, ensuring residents are immersed in a biophilic environment regardless of the weather.
-
Design Implementation: The facility utilizes expansive windows that frame the surrounding woods, but its most innovative feature is an indoor sensory garden. This year-round living space includes moss walls, indoor trees, and a water feature.
-
The Therapeutic Result: By bringing nature indoors, The Cordwainer ensures that residents’ circadian rhythms are supported even during winter months. The consistent visual presence of greenery provides a soothing environmental baseline that reduces the cognitive fatigue associated with purely artificial spaces. This immersion allows residents to benefit from the neurological relaxation response to nature 365 days a year.
Tune Nursing Home (Denmark): The ‘Nature Support Model’
Tune Nursing Home is frequently cited in 2025 and 2026 research as the foundational model for tiered access to nature based on the stage of dementia decline.
-
Design Implementation: Tune implements the evidence-based Nature Support Model, which divides its green spaces into three types based on the residents’ cognitive needs:
-
Urban Woodland/Park: For those with moderate dementia, offering winding paths and opportunities for controlled risk-taking and discovery.
-
Courtyards and Rooftops: For those needing higher supervision, providing secure, easily accessible areas with clear visual connections to the larger environment.
-
Green, Light-Filled Indoor Rooms: For those in the final stages, ensuring that even when restricted to indoors, they have restorative views of “seasonal glory.”
-

Outdoor experiences are wonderful, but not all seniors have the mobility to take a stroll in a tree-lined park.
-
The Therapeutic Result: Tune’s design demonstrates that nature remains vital through the final stages of the disease. The model shows that as residents lose higher-level cognitive functions, their emotional and sensory need for the safety and serenity of a green environment actually increases. The tiered design balances autonomy with essential security.
Moss walls and moss designs tick all of the boxes and go a step further in stimulating minds and enhancing well-being (and aesthetics) in any senior living environment. Our original inspiration for this “deep dive” into the benefits of biophilic design in senior living communities stems from an Environments for Aging article titled “Digging Deeper” by Catie Ryan, Lara Slavkin, and Jay Weingarten of RDG Planning and Design. It’s an article we return to again and again as the authors posit:
“Holistic biophilic design–that is, design that looks at the whole user experience rather than only one or two elements–targets specific health outcomes initiated by intrinsic responses to nature that are deeply embedded within human biological cycles and systems (circadian rhythms, heart rate, blood pressure, stress hormone levels and immune system)” (Ryan, Slavkin, Weingarten, 2021)
Maintenance Free Moss May (what you don’t know may surprise you):
We are currently seeking a case study project on biophilic, moss design in a senior living environment. If such a project appeals to you and you wish to collaborate and complete a case study, please contact us directly and ask to speak with The Fat Plant Society owners, Morten Klinte or Kasey L Riley.
