By the time you feel thirsty, you’re already about 2% dehydrated. That’s not a crisis, but it’s like driving with the gas light on—you’ll get there, but you’re pushing your luck. Also, thirst gets weaker as you age, so if you’re over 30, your “I need water” signal is basically a dying smoke alarm. Drink proactively, not reactively.
Another shocker: extreme dehydration can make you grumpy for no reason. That moment you snapped at your spouse for breathing too loud? It might have been thirst. You’re not a jerk—you’re a human prune. Fix it with a glass of water and an apology.

Here’s a simple formula that won’t require a PhD: take your body weight in pounds, cut it in half, and drink that many ounces of plain water daily—then add 16 ounces if you exercise. A 180-pound man? That’s 90 ounces base plus exercise water. Adjust for your climate. If you live in Phoenix, double it. If you live in Seattle, you’re basically a wet sponge already.
But don’t obsess. Your body is smarter than you think. If you’re not chugging water and your pee is pale, you’re fine. Carrying a giant gallon jug might look hardcore, but it’s also a sign you’ve been reading too many Instagram fitness influencers.
