Urbanization, screen dependency, and the changing nature of childhood and parenting have led to increased time indoors, creating physical and emotional distancing from nature and time spent in natural environments. Substantial evidence from observational and intervention studies indicates that overall time spent in nature leads to increased perceived value for connectedness to nature and, subsequently, greater pro-environmental attitudes and behaviors (PEAB). This narrative review of the recent literature evaluates associations between time spent in nature with values ascribed to nature and nature connectedness, as well as PEAB. We discuss the influence of nature exposure and education in childhood on subsequent development of PEAB in adulthood. We analyze theoretical frameworks applied to this research as well as metrics employed, populations studied, and individual and societal values before presenting limitations of this research. We conclude with suggestions for future research directions based on current knowledge, underscoring the importance of promoting time spent in nature and PEAB in the face of growing challenges to planetary health. Research indicates that overall time spent in nature, regardless of the quality of environmental conditions, leads to increased perceived values ascribed to nature, which is associated with PEAB; however, this literature is predominantly cross-sectional. Furthermore, personal and social factors may influence PEAB. Thus, more longitudinal studies that consider these factors are needed to assess the duration and frequency of time spent in nature in childhood and its impact on PEAB throughout the life course. Identifying contexts which cultivate PEAB and reverse alienation from nature beginning in childhood may better sensitize adults to the urgency of environmental issues such as climate change, which adversely impact individual and environmental health.

Human interaction with nature is vital for physical health and mental wellbeing, and positions a community to be resilient to urban stressors. Yet urban development continues to put pressures on natural areas within urban boundaries. As a case in point, Seattle’s largest park, Discovery Park, of over 500 acres, is often under threat of some form of development. The central question of this study was whether the benefits to visitors of Discovery Park depend, in no small measure, on the park’s very size and relative wild landscape. Toward addressing this question, 320 participants provided written narratives (through our web portal) about the meaningful ways in which they interacted with nature at Discovery Park. Each individual narrative was then analyzed and coded using an Interaction Pattern (IP) approach, which provides characterizations of human-nature interaction that have ontogenetic and phylogenetic significance. Results revealed 520 Interaction Patterns (IPs). The most frequently occurring IPs clustered under the keystone IPs of Encountering Wildlife (27%), Following Trails (14%), Walking to Destination Spots in Nature (8%), Gazing out at the Puget Sound or Mountains (6%), Walking Along Edges of Beach or Bluffs (5%), and Walking with Dogs (4%). Results also revealed that visitors’ meaningful interactions with nature in Discovery Park depended on the park’s relative wildness. For example, (a) 77% of participants’ IPs depended on Discovery Park’s relative wildness; (b) of the participants who specified an especially meaningful experience with nature, 93% of them had an interaction that depended on Discovery Park’s relative wildness; and (c) of the participants whose IPs were linked to other aspects of the nature in the park or to their own positive mental states, 94% and 96%, respectively, had an interaction that depended on Discovery Park’s relative wildness. Discussion focuses on how human interaction with large and relatively wild urban parks helps reverse the trend of environmental generational amnesia, and a domination worldview, and thus should be prioritized in urban planning.

We provide consensus on the benefits of nature experience for mental health, and a model for integrating them into urban design., A growing body of empirical evidence is revealing the value of nature experience for mental health. With rapid urbanization and declines in human contact with nature globally, crucial decisions must be made about how to preserve and enhance opportunities for nature experience. Here, we first provide points of consensus across the natural, social, and health sciences on the impacts of nature experience on cognitive functioning, emotional well-being, and other dimensions of mental health. We then show how ecosystem service assessments can be expanded to include mental health, and provide a heuristic, conceptual model for doing so.

Natural features, settings, and processes in urban areas can help to reduce stress associated with urban life. In this and other ways, public health benefits from, street trees, green roofs, community gardens, parks and open spaces, and extensive connective pathways for walking and biking. Such urban design provisions can also yield ecological benefits, not only directly but also through the role they play in shaping attitudes toward the environment and environmental protection. Knowledge of the psychological benefits of nature experience supports efforts to better integrate nature into the architecture, infrastructure, and public spaces of urban areas.

In terms of physical and psychological well-being, does it matter that on a worldwide level we are replacing interactions with actual nature with technological nature—technologies that mediate, simulate, and augment the natural word? Research from three forms of technological nature are reviewed: a technological nature window, robot pets, and a telegarden. Results suggest that while interacting with technological nature is better than nothing, it is not as good as interacting with real nature. A concern with accepting technological nature is that it can shift the baseline downward for what counts as optimal well-being, as people across generations lose experiences with healthy baselines, a process referred to as environmental generational amnesia. One result is that we ask too little of the idea of urban sustainability, confusing biological living with human flourishing.

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.We propose a research agenda on nature contact and health, identifying principal domains of research and key questions that, if answered, would provide the basis for evidence-based public health interventions.We identify research questions in seven domains:Nature contact may offer a range of human health benefits. Although much evidence is already available, much remains unknown. A robust research effort, guided by a focus on key unanswered questions, has the potential to yield high-impact, consequential public health insights. https://doi.org/10.1289/EHP1663.
