Somehow, the idea that cold water makes you sick has outlived bell-bottoms and pet rocks. It’s a myth—a stubborn, catchy one, like a pop song you can’t unhear. Your body is a furnace, not a flimsy umbrella; it regulates its own temperature just fine.
So where did this belief come from? Probably from Grandma seeing someone shiver after a cold drink and blaming the water instead of the actual germy toddler they’d been kissing. Misattribution is a powerful trickster.
