The immune responses during and following exercise have been studied extensively and there are a number of review papers, symposia, and presentations concerning immune responses during exercise. In contrast, there has been relatively few review papers, and no conference symposia, specifically examining immune function during exposure to various environmental extremes. The purpose of this symposium is to review the current state of knowledge in the area of immune function and environmental exposure with special emphasis placed on possible mechanisms of action. Dr. Rhind will discuss immune function during exercise-heat stress and the specific role of exertional hyperthermia on cell populations and function. Dr. Castellani will review the interactive effects of cold exposure and exercise on immune cell populations and cytokines, with particular emphasis on studies done in collaboration with DCIEM. Dr. Pedersen will discuss the effects of severe exercise and hypoxia on immune function. Finally, Dr. Sonnenfeld will examine and review the literature concerning the impact of microgravity and space travel on immune function.
