Stop stressing about exact milliliters. Your body is not a precise machine—it’s more like a 1998 Honda Civic with a check engine light that’s always on. Drink when you’re thirsty, eat your fruits and veggies, and don’t chug a whole liter before bed unless you want to wake up at 3 AM for a bathroom sprint.
If you really want a number, go with 1500–2500 ml as a friendly guide. But if you forget and drink a little less one day? The world won’t end. You’ll just have a marginally better excuse for that afternoon brain fog. Hydration is a practice, not a puzzle. So raise your glass—make it a toast to common sense.
