You might be thinking, “Why the heck do I need this exact number?” Well, you probably don’t. The whole “eight glasses a day” rule? That was a random guess from a 1945 study. 75 ounces is just a modern, slightly bossy update.
It’s especially a thing if you work out. If you sweat like I do (immediately, and for no good reason), you need more. Do you live in Arizona? Drink more. Is it winter? Drink the same amount, but complain about it.
The truth? Your body is smarter than a calculator. If your pee is the color of weak lemonade, you’re golden. If it’s the color of apple juice, you’re dehydrated. If it’s clear? Honestly, you’re probably overdoing it. Chill out.
