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. If you would like to submit an article to be featured in the database, please email

Daily exposure to virtual nature reduces symptoms of anxiety in college students

Authors:Matthew H.E.M. Browning, Seunguk Shin, Gabrielle Drong, Olivia McAnirlin, Ryan J. Gagnon, Shyam Ranganathan, Kailan Sindelar, David Hoptman, Gregory N. Bratman, Shuai Yuan, Vishnunarayan Girishan Prabhu and Wendy Heller | | Scientific Reports | Scientific Reports: 1239

Exposure to natural environments offers an array of mental health benefits. Virtual reality provides simulated experiences of being in nature when outdoor access is limited. Previous studies on virtual nature have focused mainly on single "doses" of virtual nature. The effects of repeated exposure remain poorly understood.

Exposure to urban greenspaces has been linked to improved health outcomes for prevalent conditions. Studies have observed traditional block greenspaces, whereas linear trail systems could maximise health impacts by reaching greater population percentages.

Time spent in nature (TSN) is related to improved health and well-being; however, many adults spend little time in nature. Interventions based on health behavior theories may be effective at increasing TSN.

Measuring Attitudes Toward Spending Time in Nature: A Validated Measurement Tool

Spending time in nature is proven to be good for your health. Interventions based on health behavior theories may be effective at increasing time spent in nature only if we have a better understanding of attitudes towards this behavior.

Stress recovery from virtual exposure to a brown (desert) environment versus a green environment

Authors:Jie Yin, Gregory N. Bratman, Matthew H.E.M. Browning, John Spengler and Hector A. Olvera-Alvarez | | Journal of Environmental Psychology | Volume 81

The beneficial association between nature contact and human health is often explained with psycho-evolutionary frameworks such as stress reduction theory and the savanna hypothesis. However, evidence is limited on how natural environments that are not green affect stress. One example is the desert, which does not offer affordances for nourishment or safety in an evolutionary sense.

Research Article

Development and validation of self-efficacy and intention measures for spending time in nature

Authors:Jay E. Maddock, Courtney Suess, Gregory N. Bratman, Carissa Smock, Debra Kellstedt, Jeanette Gustat, Cynthia K. Perry and Andrew T Kaczynski | | BMC Psychology | Volume 10, issue 1 (December 2022): 51

The purpose of this study was to develop and evaluate the reliability and validity of self-efficacy and intentions measures for time spent in nature (TSN). TSN is related to improvement in psychological well-being and health, yet most American adults spend very little time in such settings.
