She came in on a Tuesday looking tired in a way that had nothing to do with sleep. Head felt foggy. A dull ache behind her eyes most afternoons. She was doing everything right, she said, sleeping well, eating well, keeping up with her workouts. The first thing I asked her was how much water she was drinking. She paused. That pause told me everything.
Your brain is about 75% water. Every thought you have, every signal your body sends, every bit of focus you’re trying to hold onto runs on fluid. And here is the thing most people don’t know: by the time you feel thirsty, your brain has already been running short for a while. The fog, the headache, the flat energy before lunch, those are your body asking for water, not announcing it.
In Scottsdale, this matters more than almost anywhere else. The desert air pulls moisture off your skin even when you’re just walking to your car, even when you don’t feel sweaty. The Arizona Department of Health Services recommends at least 64 ounces of water a day as a starting point, and if you’re active or spending time outside, you need more. Most people I see are well below that before they’ve even had breakfast.
The fix is simpler than most people expect. Drink a full glass of water before your first cup of coffee. Keep a bottle at your desk and drink before each meal. Check your urine, light yellow means you’re doing well, dark yellow means your body is running low. These are not complicated habits, but done every day they change how you feel by mid-afternoon in ways that are hard to overstate.
Water is where I always start, because it is where so many answers actually live. When someone drinks more and the fog lifts and the headaches ease, that is not a coincidence, that is the body getting what it needed. And when those things improve but don’t fully go away, that gap is information worth looking into. We’re here when you’re ready.
