You’ve heard it a million times: drink eight 8-ounce glasses of water a day. That’s exactly 0.5 gallons. Cute, right? But here’s the ironic part—there’s zero scientific evidence that this number came from a study. It was basically a guess, repeated so often that it became a fact.
So, if your anxiety is tied to hitting that half-gallon mark, you can stop panicking. Your body doesn’t care about a rule invented for a book cover. It cares about thirst, sweat, and what you ate for lunch.
