Forget counting cups. Look at your pee. Pale yellow or clear? You’re gold. Dark yellow or amber? Drink up—you fossil. This is the most reliable hydration test ever invented, and it costs zero dollars.
Bonus: if your pee looks like iced tea, stop reading and go chug two glasses right now. Seriously. Go.
When You Actually Need More Water
Okay, there are times you really should force extra fluids. Like when you’re exercising and sweating like a sinner in church. Or when it’s hotter than a jalapeño’s armpit outside. Also, if you’re sick with a fever, diarrhea, or a hangover from last night’s bad decisions.
Pregnant or breastfeeding moms? You need a bit more too. But again—listen to your body, not a random internet rule.
