We investigated the effects of recreational exposure to the natural environment on mood and psychophysiological responses to stress. We hypothesized that walking in nature has restorative effects over and above the effects of exposure to nature scenes (viewing nature on TV) or physical exercise alone (walking on a treadmill in a gym) and that these effects are greater when participants were expected to be more stressed. Healthy university students ( N = 90) were randomly allocated to one of three conditions and tested during an exam-free period and again during their exam time. Mood and psychophysiological responses were assessed before and after the interventions, and again after a laboratory stressor. All interventions had restorative effects on cortisol levels ( p < .001), yet walking in nature resulted in lower cortisol levels than did nature viewing ( p < .05) during the exam period. Walking in nature improved mood more than watching nature scenes ( p < .001) or physical exercise alone ( p < .05).

A traditional Romantic fix for the stress and strain of the everyday has been the idea of ‘getting back to nature’, exploring places of natural grandeur and beauty based on the belief in nature’s therapeutic agency on the traveller. This article introduces a theoretical framework that offers a way to explore how touristic spaces are lived within a human–non-human co-constituted affective process. It then engages with the spaces of nature-based tourism and reports findings from an ethnographic study on British-based trekking holiday to Iceland. These findings suggest that the emotions and therapeutic affect that have traditionally been reported from spending time in nature are relational outcomes; they depend both on nature’s performance and on what the individual contributes to the relations.
