The present paper aims at presenting an overview of findings relating personality hardiness to adaptation to polar environments. Several studies from the Operational Psychology Research group at the University of Bergen have depicted individual characteristics of high hardy subjects involved in stressful activities in polar environments. These high hardy subjects have superior coping skills, are less influenced by environmental stress, show increased motivation during endurance activities, and have a more adaptive biological stress response. It could be assumed that explorers undertaking solo expeditions in polar environments would represent extremely hardy people. Thus, in addition to previously reported studies on hardiness in polar environment, the results from two previously published papers are presented and re-interpreted.
