So, how much liquid should you actually drink? According to the U.S. National Academies of Sciences, Engineering, and Medicine, the general recommendation is about 3.7 liters (125 ounces) per day for men, and 2.7 liters (91 ounces) per day for women. That’s the official, science-approved number—but before you run off to buy a gallon jug, keep reading.
Important note: that total includes all fluids—water, coffee, tea, soup, that sneaky splash of milk in your cereal. Yes, you read that right. Your morning latte counts. Don’t let anyone guilt-trip you into thinking caffeine dehydrates you. Unless you’re drinking a jet fuel blend, you’re mostly fine.
