Overview
There are no previous studies of the effects of a combination of whole-body immersions in hot and cold baths on adaptive responses and health-related markers. Thus, the primary aim of this project is to determine whether interventions consisting of whole body immersion in hot and cold baths over 16 days develop heat and/or cold adaptation by remodeling thermoregulatory, metabolic, cardiovascular and physiological responses, and the secondary aim is to determine if current cold-hot acclimation has any effects on physical and mental health-related markers.
