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

Research Brief

Validating Nature Images to be used in Nature and Health Research using fMRI Technology

This study fills a void in the literature by both validating images of nature for use in future research experiments and examining which characteristics of these images are most representative of nature. Understanding semantic categories most representative of nature is useful in developing nature-centered interventions and research that uses neuroimaging modalities, such as fMRI studies.

Research Article

The affective benefits of nature exposure

Authors:Gregory N. Bratman, Hector A. Olvera-Alvarez and James J. Gross | | Social and Personality Psychology Compass | Volume 15, Issue 8

Mounting evidence demonstrates that nature exposure can have affective benefits. These include behavioral and psychophysiological responses consistent with (a) decreases in stress and negative affect; and (b) increases in subjective well-being and positive affect. What is less clear, however, is what mechanisms are responsible for these effects.

Research Article

Affective Benefits of Nature Contact: The Role of Rumination

Authors:Gregory N. Bratman, Gerald Young, Ashish Mehta, Ihno Lee-Babineaux, Gretchen C. Daily and James J. Gross | | Frontiers in Psychology | Volume 12

Mounting evidence shows that nature contact is associated with affective benefits. However, the psychological mechanisms responsible for these effects are not well understood. In this study, we examined whether more time spent in nature was associated with higher levels of positive affect in general, and lower levels of negative affect and rumination in general.
