The goal of this observational study is to examine how different physiological markers change over a two-day period after long-duration whole-body cold-water immersion in healthy young men and women. Specifically, the study aims to address the following questions: * How do kynurenine pathway metabolites change after cold exposure? * How do stress markers change after cold exposure? * How do cytokine levels change after cold exposure? * How do white blood cells count and distribution change after cold exposure?
