                             Some of these strategies will be aided through training with new technolo-
                             gies that create virtual environments, allowing individuals to safely test their
                             limits and make recoverable mistakes.



                             Summary

                             Extreme environments challenge individuals through physiological mecha-
                             nisms that increase physical and psychological fatigue, adversely aff ect mood
                             and neurocognitive status, and increase susceptibility to injury and disease.
                             These limiters help prevent more serious injury or death in conditions that

                             may exceed an individual’s ability to further compensate in extreme condi-
                             tions. Resilient individuals are able to push these limits and more fully realize
                             their performance potential in extreme conditions. This thesis is centered on

                             discoveries so that people can learn to “think warm thoughts” and perform
                             better in cold environments; leaders can inspire groups to adopt a positive
                             mental state that enhances their survival in harsh environments; and an atti-

                             tude of invincibility enables athletes to eke out the winning difference in elite

                             physical performance. This expression of human genetic resilience has been
                             shaped by adaptations favoring endurance performance and is signifi cantly
                             moderated by exercise, mental processes, and psychosocial factors. Examples
                             of resilience extremes provide insights into physiological mechanisms for the
                             variations in human performance, survival, and success. Recent advances in

                             brain physiology can benefit this research frontier, connecting behavior and
                             perception to neurophysiological outcomes in extreme environments.
