AI-Summary

What this Trial Is About

The goal of this clinical trial is to learn about the processes occurring in the kidneys while under heat stress in healthy volunteers. The main questions it aims to answer are: * How do the chemicals produced by the body change under conditions of higher versus lower heat stress? * What role does a specific area of the body's metabolism, known as NAD+ metabolism, play in the body's response to heat stress, and can this response be modified by taking vitamin B3?
