Hydration: The Simplest Thing Nobody Does Right
Sept. 14/26
I spent twenty-seven summers watching a thermometer do things that would alarm a person who hadn't grown up with it. Sacramento Valley heat in the summer doesn't announce itself gently. It sits on you by nine in the morning and doesn't let up until well after the sun's gone down. You learn things about water out there that no article ever quite gets across, because the article is written by someone who's never had to keep a body working through a hundred and eight degrees with a full day of irrigation checks ahead of him.
The first thing I learned is that thirst is a lagging indicator. By the time you feel it, you're already behind — already a quart or two short of where you should have been an hour ago. We didn't wait for thirst on the ranch. We drank on a schedule, the same way you'd check a pump on a schedule, because waiting for the warning light meant the pump had already been running dry for a while. I still don't entirely trust thirst as a guide. It shows up late and it undersells the problem.
The second thing was subtler, and it took longer to notice. Heat doesn't just take water from you — it takes your judgment right along with it. I've watched grown men who knew better make small, stupid decisions on the hottest days: skip a break, push one more row, forget to reach for the jug sitting right there in the truck bed. Dehydration doesn't announce itself as dehydration. It shows up as irritability, as a headache you blame on the glare, as a kind of fog that makes the next decision a little worse than it should be. You don't feel dry. You feel dumb and tired and a little off, and it's easy to miss what's actually happening.
What the research says about hydration these days is mostly reasonable — that most people walking around in ordinary climate-controlled lives are mildly under-hydrated more often than they'd guess, that the old eight-glasses number was never much more than a decent guess dressed up as a rule, that your actual need moves around with your size, your activity, the weather, what you ate. All true enough. But the studies are done in labs, with people who show up for the study. The field is different. Nobody's checking your urine color at your desk at 2 p.m. Nobody's reminding you between the second and third cup of coffee that you haven't had plain water since you woke up.
That's really the whole problem, and it's not complicated. Most of us load up on coffee first thing, which is a diuretic doing the opposite of what we need right when we need it most, and we don't touch water until we're already thirsty — already behind, the way I was talking about a minute ago.
So here's what I'd try, if I were you, for one week: before the coffee touches your lips, drink a full glass of water. Not instead of the coffee — before it. It's a small habit, and I'm suspicious of habits that promise to change your life, because most of them don't. But this one costs you nothing, takes thirty seconds, and gets you back ahead of the problem instead of chasing it all morning, which is exactly the position I spent half my working life trying to stay in.
This is a record of what I've read and observed, not medical advice. I'm not a doctor, and nothing here should replace a conversation with one. Any drug, dose, or treatment decision -- Mounjaro included -- is between you and your own physician. What works in my reading or in the field doesn't automatically apply to your situation.
