Hydrate to Keep Your Cool

Proper hydration is key to comfort when the temperatures soar, says LifeHacker. Water is like a coolant that keeps the body cool — and if you’re sweating it out, it must be replaced. Drink plenty of water (preferably uncarbonated water, which has proven more effective for hydration). Don’t rule out other beverages when you’re trying to keep cool, though; even coffee and beer (in moderation) can aid in hydration. Coffee and other caffeinated beverages tend to increase the body’s temperature, however, temporarily thwarting hydration’s cooling effect, while excessive alcohol intake depletes the body of fluids and nutrients.
