Here’s a more personalized formula that doesn’t involve advanced calculus. Take your weight in pounds, divide by two, and that’s your ounces. A 150-pound person would aim for 75 ounces. See? You’re not a math failure.
This rule accounts for the simple fact that bigger bodies need more water. It’s like a bigger engine needs more gas—though, in this case, the gas is clear and boring. You’re welcome for that image.
But don’t get obsessive. If you’re a 200-pound lumberjack, 100 ounces is a target, not a punishment. And if you’re a 100-pound fairy? Fifty ounces might be plenty.

Thirst is a sneaky liar
Your body’s thirst signal is actually behind the ball. By the time you feel thirsty, you’re already slightly dehydrated. That’s the equivalent of your car’s gas light coming on when you’re already in the breakdown lane.
So, don’t wait for your mouth to feel like the Sahara. Sip water throughout the day like a civilized hummingbird. Keep a bottle on your desk, in your bag, or next to your cat’s water bowl (don’t share, please).
And coffee, tea, and soup do count toward your total. Surprise! Caffeine isn’t the dehydration demon we once thought. Just don’t replace all your water with energy drinks unless you want to vibrate through a wall.
