In a controlled heat exposure (38°C), two groups are compared: Group 1 is well hydrated; Group 2 is mildly dehydrated after 12 hours of fluid restriction. Both groups show similar initial increases in skin blood flow, but Group 2 exhibits a smaller increase in measured sweat rate and a greater rise in core temperature over 30 minutes. The central thermoregulatory principle is eccrine sweating for evaporative heat loss. Which outcome is most consistent with the observed difference in Group 2?
