Advancing Environmental Epidemiology to Assess the Beneficial Influence of the Natural Environment on Human Health and Well-Being.

Environmental health research can be oriented across a continuum of effects ranging from adverse to cobenefits to salutogenic. We argue that the salutogenic end of the continuum is insufficiently represented in research and as a basis for environmental protection, even though there is growing evidence that the natural environment plays a critical role in blunting adverse effects and promoting human health and well-being. Thus, we advocate for advancing environmental health research through environmental epidemiology that more fully and directly accounts for the salutogenic effects of the natural environment on individual well-being by (1) defining "natural environments" broadly, from pristine natural areas to urban green infrastructure; (2) considering exposure comprehensively to encompass residential, occupational, and recreational settings, local and distant, day-to-day and occasional; (3) doing individual-level assessments that include both health and well-being outcomes and one's experience of nature, including potential mediation by connectedness to nature and individual perceptions and preferences, as well as sociocultural and demographic effect modifiers; and (4) collecting longitudinal and nationally representative data.
