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):
Let’s delve into the specific benefits of moss walls and designs (as core biophilic design elements) in senior living facilities that provide a highly appealing and cost-effective visual connection with nature–
Further, research shows that for memory care, vertical elements are more effective than floor-level plants because they remain in the direct line of sight and do not require the physical strain of bending over, which can cause disorientation in elderly residents.
Note how we install the wall in panels, making any (rarely) needed repair quick and easy for any facilities team to manage.
Understanding Biophilic Design in Senior Living Settings:
- Biophilic design seeks to reconnect people with nature by incorporating natural elements, patterns, and materials into the built environment.
- In senior living facilities, biophilic design aims to improve residents’ quality of life by fostering connections with nature, reducing stress, and enhancing overall well-being.
- Elements of biophilic design include natural light, indoor plants, views of nature, natural materials, and green walls.

Challenges of Traditional Greenery in Senior Living Settings:
- While traditional greenery like potted plants and gardens offer benefits, they also pose challenges in maintenance, especially in senior living environments.
- Seniors may have limited mobility, making it difficult for them to navigate around plants and/or care for them.
- Maintenance of traditional greenery requires resources such as water, labor, and expertise, which may be scarce or costly in senior living settings.
The Rise of Maintenance-Free Moss Design:
- Maintenance-free moss design offers a sustainable and hassle-free alternative to traditional plants.
- Moss walls and installations require minimal upkeep, making them ideal for senior living facilities where staff resources may be limited. Unlike live plants, moss doesn’t require watering, pruning, or fertilizing, reducing maintenance and labor costs. The Fat Plant Society moss walls and designs remain lush and green for a decade (or more) which is longer than many furnishings hold up to wear and tear. Additionally, moss walls and designs are easily repaired should they incur damage.
Benefits of Maintenance-Free Moss Design in Senior Living Settings:
- Improved Air Quality: Moss naturally absorbs pollutants, contributing to better indoor air quality, which is crucial for seniors with respiratory issues.
- Stress Reduction: Studies have shown that exposure to nature, even in the form of moss, can reduce stress, anxiety, and depression among seniors.
- Noise Reduction: Moss acts as a natural sound absorber, helping to minimize noise levels in shared spaces, promoting tranquility and relaxation.
- Biophilic Engagement: Moss designs provide visual and tactile stimulation, engaging residents with nature and enhancing their connection to the environment.
- Aesthetics: Moss walls and installations add natural beauty and tranquility to interior spaces, creating a calming ambience that reduces anxiety.
- Slowing of memory issues and anxiety reduction. Recent studies indicate that a year-round visual connection to nature may slow the progression of memory issues and greatly enhance memory care in long-term care and residential settings (the return on investment here is both qualitative and quantitative, given the impact on residents, staff, and the enhancement of well-being for both).
Environmental Sustainability:
- Moss is a sustainable material that can be harvested without harming natural ecosystems, making it an eco-friendly choice for senior living facilities committed to environmental stewardship.
- Unlike live plants, moss doesn’t require soil or significant water resources, further reducing its environmental footprint.
- By choosing maintenance-free moss design, senior living facilities can demonstrate their commitment to sustainability, responsible resource management, and the health and wellness of residents and staff alike.
- We exclusively utilize American-grown moss at The Fat Plant Society, further reducing the carbon footprint.
Opportunity for Case Studies on Memory Care with a Visual Connection to Nature:
- The Journal for Aging and Environment published a paper titled, “Biophilic Design Strategies in Long-Term Residential Care Environments for Persons with Dementia” by Terri Peters and Stephen Verderber that examines memory issues in light of recently built state-of-the-art Long Term Care (LTC) settings for persons with dementia and related cognitive disorders. Residents’ engagement with and proximity to nature and landscape, and transactions with biophilia-inspired artifacts was the principal focus.
- “This has been the first published literature review specifically on biophilia in the context of long-term care environments for persons with dementia and related cognitive disorders. Published studies relevant to LTC environmental design span numerous disciplines, including psychology, education, sociology, philosophy, toxicology/public health, urban design, landscape architecture, and architecture. That said, there is a growing interest in biophilic design principles on the part of designers, LTC administrators, and direct caregivers.” (Peters and Verderber, 2020)
- Peters and Verderber conclude (as we have concluded in our initial examination of senior living environments and long-term care facilities and corresponding research) that additional studies and case studies will enable architects, developers, and designers to better understand the benefits of visual connection with nature and other biophilic design strategies. “The need is pronounced for evidence-based research on the potential therapeutic benefits of biophilia, together with resident safety and infection control (Anderson et al., 2020).
- An additional study, presented by Indonesian scholars at the IOP Conference Series Earth and Environmental Science, concluded the “increase of biophilic design value can affect the decrease of dementia level in elders with the age range of 60-85 years old who lived in STW Ria Pembangunan, Cibubur. Therefore, the application of biophilic design in housing, or, [the] other buildings are highly recommended as a preventive method to reduce the dementia level in Indonesia.” Scholars R Felly and D Susanto make this important note: “research on the appropriate quantity of nature presented into a building has never been conducted. Moreover, further research is required to determine which is the best among all 14 biophilic design patterns that are highly impactful on the elder’s memory
factor.” (Felly and Susanto, 2020).

The Standard of Care in 2026
As we move through 2026, the senior living industry is adopting biophilic design as a required standard, not a luxury.
Nature-supported care offers a dignity-first approach where the environment itself acts as a caregiver.
Incorporating biophilic design principles, particularly a visual connection to nature through maintenance-free moss design, into senior living facilities offers a multitude of benefits. From reducing stress to promoting environmental sustainability to enhancing memory care, moss installations contribute to creating healthy, vibrant, and sustainable environments for older adults. As the demand for senior living communities continues to grow, embracing biophilic design becomes not just a luxury but a necessity in ensuring the wellness and happiness of residents.
The evidence is clear: when nature is constant and in view, the sensory overload that accelerates memory loss is reduced, emotional distress is mitigated, and neural pathways to long-term memory can be preserved longer.
Nature is no longer just “scenery”—it is medicine.
