To say that hydration is an invention is only a slight exaggeration. Water bottles have become a crucial accessory — a status symbol. How did that happen? This week we bring you an episode from our friends at the Slate podcast Decoder Ring. They investigate how bottled water transformed itself from a small, European luxury item to the single largest beverage category in America. It took savvy marketing from brands like Gatorade and Perrier, who pushed the idea that dehydration was a pervasive problem to be solved. Today hydration is a wellness cure-all, but the science doesn’t exactly match the marketing.
