Summary

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.

Interventions

Type	Name	Description
OTHER	16-day hot and cold acclimation	Acclimation program will consist of 8 brief cold water immersions (CWI; 14°C 5 min) and 8 hot water immersions (HWI; 45°C 5 min). Heat and cold sessions will be performed on separate days (i.e., 1st day hot exposure, 2nd day cold exposure, 3rd day hot exposure, etc.).
