Purpose
This paper aims to examine how sadness-induced hedonic choice patterns can be attenuated through a micro-restorative wilderness experience, countering helplessness.

Design/methodology/approach
Drawing upon theories of emotion appraisal and environmental psychology, this study uses logistic regression and Hayes PROCESS Macro Model 7 to examine the conditional effect of wilderness elements present in the service environment on sad individuals’ food choices via helplessness.

Findings
The study demonstrates the restorative and psychological benefit of reduced helplessness for “wilderness: a micro-restorative environment”. While Sadness increases the choice of hedonic food items (sweet and salty), exposure to wilderness (versus non-wilderness) service environment attenuates such choice patterns. Moreover, the appraisal of helplessness mediates this conditional effect.

Research limitations/implications
Incorporating diverse sampling, expanding investigation beyond food-related behaviour, exploring multisensory design, examining learned helplessness as a stable mechanism, further emphasising ecological validity and identifying boundary conditions will provide broader insight.

Practical implications
Marketers can strategically moderate the sadness effect by leveraging “wilderness” elements in service design to induce effective decision-making. Consumers may benefit from enhanced self-control and policymakers could explore a simple yet globally resonant tool to address obesity, integrating wilderness into urban settings.

Originality/value
The study provides a granular approach to the effect of sadness on food choice. It offers wilderness, a novel intervention strategy that operates at the firm level, is subconscious, non-consumption orientated and has the potential to become a global intervention to mitigate the effect of sadness. The mechanism of helplessness further adds dimensionality to the literature on nature, affect and health-change behaviour.
