Forget complicated math or apps that yell at you to drink. Listen to your body. If you’re active, drink before, during, and after. If it’s hot out, double up. If you’re pregnant or nursing, add 10 to 20 extra ounces—you’re making a human, not a sandcastle.
Here’s my license-approved cheat sheet: keep a 32-ounce bottle at your desk and refill it two to three times a day. That’s 64 to 96 ounces. Plus whatever you get from food. If you’re still thirsty at night, take a sip before bed—but not a giant gulp, or you’ll wake up at 3 a.m. for a pee walk.
One final warning: water intoxication is a real thing. Yes, you can die from drinking too much water too fast. It’s called hyponatremia, and it flushes salt from your blood, causing your brain to swell. So don’t down a gallon in an hour to “catch up.” Your kidneys will throw a tantrum, and you’ll end up on YouTube as a cautionary tale.
In short: drink when you’re thirsty, check your pee, and don’t be a hero. Your body is a dumb, beautiful water balloon that needs refilling, not flooding. Now go drink a glass—your raisin brain will thank you.
