If you go to the gym, run after your toddler, or just live in a place where the sun actively tries to melt you, you need more. Exercise can burn an extra 0.5 to 1 liter per hour through sweat alone.
That’s not a license to ignore thirst, though. Your body is smart. If your mouth feels like a desert, drink. If your pee looks like iced tea, drink more. If you’re dizzy? Stop reading, grab a glass, and sip slowly like a civilized person.
And please, don’t be that person who chugs a liter in three seconds. That’s how you get a sloshy stomach and a mysterious side stitch. Sip, don’t sprint.
How Many Liters Should You Drink?
Here’s a cheat sheet that won’t require a calculator: Take your weight in pounds, divide by two, and drink that many ounces. For example, a 150-pound person needs about 75 ounces, which is roughly 2.2 liters.
Or, just listen to your body. Thirst is your built-in hydration alarm. If you’re yawning, getting headaches, or feeling grumpy, you’re probably dehydrated. (Pro tip: don’t use “I’m dehydrated” as an excuse to snap at your partner. They see through it.)
How Much Water Should You Drink Per Day?
Also, remember that tea, milk, and even that soda you’re hiding from your dentist all count—though water is still the MVP. Think of it as your hydration team, and water is the captain.
