Dynamics of stress and recovery and relationships with perceived environmental mastery in extreme environments

Abstract

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.
