Conventionally one would think drinking cold water would cool the body temperature. However, according to research drinking a hot beverage may help your body stay cool. The reason being that when you drink a hot drink, your body produces sweat to cool down your body temperature. Initially you may be adding heat by drinking the hot liquid, but the increased perspiration is key; when the sweat evaporates from your skin, it is able to cool down your body temperature.
