Let’s get personal. Your water needs depend on how much you sweat, how much you move, and whether you live in Arizona or Antarctica. A good rule of thumb is to drink half your body weight in ounces—so if you weigh 150 pounds, aim for 75 ounces of fluid per day. That’s about nine eight-ounce glasses, but again, that includes your morning coffee, which is about 95% water. Sorry, Matt Damon in “The Martian,” your urine is not a valid source.
Here’s a surprising fact: 20% of your daily water comes from food. Watermelon is literally 92% water, and cucumbers are basically crunchy water sticks. Even steak has water in it—though I wouldn’t recommend blending one for a hydration smoothie. So if you feel like you’re drowning in random guidelines, just eat a salad and call it a day.
Signs You’re Winning the Hydration Game
Your skin bounces back when you pinch it. You pee every two to four hours, and it looks like diluted lemonade. You don’t have a headache that feels like a tiny goblin is tapping on your skull. And most importantly, you don’t wake up with a cotton-mouth demon at 3 a.m. If you check all those boxes, you’re doing great. Stop obsessing over that fancy water bottle’s LED lights.
How Much Water Do We Need To Drink, According To Our Weight?
One more thing: exercise changes everything. If you’re working out for more than an hour, especially in heat, you need to drink before, during, and after. But don’t trust the “drink eight ounces every 15 minutes” rule from your gym bro—that’s how you end up sloshing your way through a squat like a human water balloon. Listen to your body, and maybe grab a sports drink with electrolytes if you’re sweating buckets. Otherwise, tap water is the unsexy, perfect hero.
