A Hot Beverage During Soaring Temperatures May Help You Cool Down — But Only When the Weather Is Dry

Drinking hot beverages in hot, dry weather can actually help you cool down by triggering sweat production, which in turn facilitates evaporative cooling. However, this cooling effect doesn't work in humid conditions because sweat doesn't evaporate easily, leading to a buildup of heat. This insight could be particularly useful for people living in arid regions, where hot drinks might help manage the heat better than cold ones. Understanding this could change how people approach hydration strategies in extreme heat.
