This study investigated the dynamics of stress and recovery responses and their relationships with perceived environmental mastery during one-year of polar winter-over expeditioners in distinct environmental conditions of sub-Antarctic and Antarctic polar station. The findings of multilevel analysis suggested that the several stress and recovery responses experienced by the winterers were characterized by diverse dynamics according to the severity of the environment. Furthermore, perceived environmental mastery impacted differently the dynamics of these responses. This multidimensional study highlights the complex evolution of stress and recovery in these extreme situations and the central role of environmental mastery on the temporal patterns of these psychological dimensions with potential salutogenic effects. Practical recommendations for improving environmental mastery at the different stages of the mission including psychoeducation, monitoring and psychological preparation are proposed.

本研究调查了在亚南极和南极极地站的不同环境条件下，极地越冬探险者一年期间压力和恢复响应的动态及其与感知环境掌握的关系。多层次分析的结果表明，根据环境的严重程度，越冬者经历的几种压力和恢复反应具有不同的动态特征。此外，感知的环境掌握对这些反应的动态产生不同的影响。这项多维研究强调了在这些极端情况下压力和恢复的复杂演变，以及环境掌握对这些心理维度的时间模式的核心作用，并具有潜在的有益效果。
