Database

The articles in the database below represent a curated selection from our NHA (full) members and Executive Committee. Rather than being a comprehensive database, like what you would find on a mainstream database, this is a limited and curated list of articles gathered by our member. To be included, these peer-reviewed articles and resources must meet specific criteria, ensuring a foundation of quality. Articles included cover a diverse array of study types—experiments, qualitative research, and meta-analyses—all exploring the intricate relationship between nature and well-being. Priority is accorded to works addressing DEIJ matters or fostering consensus on vital topics.

Assessing changes in quality of life and independent living and working levels among AgrAbility farmers and ranchers with disabilities

Authors:Robert J. Fetsch, Danielle M. Jackman and Christina L. Collins | | Disability and Health Journal | Volume 11, Issue 2: Pages 230-236

While emerging research has focused on quality of life (QOL) levels among farmers and ranchers with disabilities, much work is still needed on this largely understudied population. The AgrAbility Project, a USDA initiative, offers pragmatic solutions to increase farmers and ranchers with disabilities' QOL and ability to work and live independently (ILW).

Urban Mind: Using Smartphone Technologies to Investigate the Impact of Nature on Mental Well-Being in Real Time

Authors:Ioannis Bakolis, Ryan Hammoud, Michael Smythe, Johanna Gibbons, Neil Davidson, Stefania Tognin and Andrea Mechelli | | Bioscience | Volume 68, Issue 2: 134–145

This study used a smartphone app called Urban Mind to track how exposure to nature in urban environments affects mental well-being in real time. Over one week, 108 participants completed over 3,000 assessments. The results showed that natural features had both immediate and lasting positive effects on mental health, especially for individuals with high impulsivity—a trait linked to greater mental health risk. These findings highlight the importance of integrating nature into urban design to support mental well-being, particularly for vulnerable populations.

Nearby nature—A cost-effective prescription for better community health?

Authors: Andrea Watts, Kathleen L. Wolf, Stephen C. Grado and Marcus Measells |

A balanced diet and regular exercise are fundamental for good health, and a daily dose of nature may be equally important. Nearly 40 years of research has demonstrated that “metro nature”—nature found in urban environments, such as parks or tree-lined streets—provides positive and measurable health benefits and improves people’s quality of life.

Nature Contact and Human Health: A Research Agenda

Authors:Howard Frumkin, Gregory N. Bratman, Sara Jo Breslow, Bobby Cochran, Peter H. Kahn Jr., Joshua J. Lawler, Phillip S. Levin, Pooja Tandon, Usha Varanasi, Kathleen L. Wolf and Spencer A. Wood | | Environmental Health Perspectives | Volume 125, Issue 7 (July 2017): 075001

At a time of increasing disconnectedness from nature, scientific interest in the potential health benefits of nature contact has grown. Research in recent decades has yielded substantial evidence, but large gaps remain in our understanding.

Ecological Restoration based on environmental education in arid regions of the Argentinean Patagonia

Authors:Daniel Roberto Pérez, Florencia González, Maria Emilia Rodriguez Araujo, Daniela Paredes, Fernando Farinaccio, Ricardo Chrobak and Elsa Meinardi | | Repositorio Digital Institucional Universidad Nacional Del Comahue | Volume 1

This abstract discusses the evolving scope of environmental education, highlighting its shift toward a multidisciplinary approach that considers the complex relationships between social and natural systems. This contrasts with earlier models that focused mainly on the physical environment and emphasized natural sciences. The authors argue that environmental education extends beyond these models, both in theory and in practice, offering a broader and more integrated framework.

Outside our Doors: the benefits of cities where people and nature thrive

Authors: Erin House, Caitlyn Bay O'Connor, Kathleen L. Wolf, Jessie Israel and Tashina Reynolds |

We are pleased and honored to introduce this milestone report from The Nature Conservancy. The authors have worked carefully to present a comprehensive analysis of current evidence on how our human communities need nature in and around them to thrive. This report presents a panoramic view of how our cities and towns benefit from nature—on the streets, next to schools and hospitals, outside our windows; everywhere people are, we can benefit from nature.

Nature experience reduces rumination and subgenual prefrontal cortex activation

Authors:Gregory N. Bratman, J. Paul Hamilton, Gretchen C. Daily and James J. Gross | | Proceedings of the National Academy of Sciences of the United States of America (PNAS) | Volume 112, Number 28: 8567-8572

Urbanization has many benefits, but it also is associated with increased levels of mental illness, including depression. It has been suggested that decreased nature experience may help to explain the link between urbanization and mental illness.

Exploring connections among nature, biodiversity, ecosystem services, and human health and well-being: Opportunities to enhance health and biodiversity conservation

Authors:Paul A. Sandifer, Ariana E. Sutton-Grier and Bethney P. Ward | | Ecosystem Services | Volume 12

As biodiversity declines rapidly due to human pressures, we are beginning to recognize the important health benefits of experiencing nature. This study reviews existing research on the links between biodiversity, ecosystem services, and human health. While there is strong evidence connecting nature exposure to health benefits, especially through microbial diversity, many studies lack depth and causal clarity. The authors call for more rigorous research, better land-use planning focused on human well-being, and collaboration across disciplines to strengthen the connection between nature and health for greater resilience in both people and ecosystems.

The benefits of nature experience: Improved affect and cognition

Authors:Gregory N. Bratman, Gretchen C. Daily, Benjamin Levy and James J. Gross | | Landscape and Urban Planning | Volume 138: 41-50

This study investigated the impact of nature experience on affect and cognition. We randomly assigned sixty participants to a 50-min walk in either a natural or an urban environment in and around Stanford, California. Before and after their walk, participants completed a series of psychological assessments of affective and cognitive functioning.

The benefits of mystery in nature on attention: assessing the impacts of presentation duration

Authors:Andrew M. Szolosi, Jason M. Watson and Edward J. Ruddell | | Frontiers in Psychology | Volume 5

This study explored how "mystery" in natural settings—scenes that suggest the possibility of new information—affects attention and memory. Using a recognition memory task with 144 participants, researchers found that images rated high in mystery led to better recognition performance, especially with longer viewing times. This effect was mediated by increased feelings of fascination, supporting the idea that mysterious nature scenes more effectively engage effortless attention. The findings align with Attention Restoration Theory, suggesting that not all natural environments are equally beneficial for cognitive restoration.
