Science says the average guy needs about 3.7 liters (15.5 cups) daily, and the average woman needs 2.7 liters (11.5 cups). That sounds like a lot—until you remember that “water” isn’t just what comes from your tap.
Your morning coffee counts. That juicy apple counts. Even the soup you had for lunch counts. If you ate a watermelon, congratulations—you basically just drank a glass of water with extra steps. Your body is a sneaky recycler.
Don’t panic if you haven’t hit some magical number. Your brain actually has a built-in water meter: thirst. If you feel parched, drink. If your pee looks like lemonade (not apple juice), you’re golden. If it’s dark, yeah, grab a bottle—but don’t chug it like you’re in a frat party.
