There’s no magic number for everyone, and that’s actually liberating. You get to be your own hydration detective.
Keep a glass at your desk, eat water-rich foods like cucumbers and berries, and check that pee color like a proud scientist. Your body knows what it needs—you just have to listen.
And the next time someone asks you, “how much water do you drink in a day?” you can smile and say, “Enough to keep my brain from shrinking.” Cool, right?
