Heat Risk, Hidden Diagnosis: What Summer Reveals About the Body
There is something Jeremy Clarkson understood instinctively that most of us resist — that the body keeps its own schedule, indifferent to our plans, our public personas, our careful management of how we appear to the world. He filmed an entire season of *Clarkson's Farm* while carrying a cancer diagnosis privately, and viewers who thought they were watching a man argue with tractors were, it turns out, watching something else entirely. The finale landed like a door swinging open onto a room nobody knew was there.
I'm not going to dwell on the diagnosis itself. What interests me more is the instinct to keep it quiet — and what that reveals about how little space we give people, publicly or privately, to be unwell without it becoming the whole story.
Because health right now is everywhere and nowhere simultaneously. We are tracking sleep cycles on smart rings, booking sunrise yoga at Four Seasons properties on the Red Sea, injecting peptides because an influencer with good lighting told us it was longevity in a vial. We are, collectively, performing wellness with more sophistication than we are actually practising it.
The detail that stayed with me this week was quieter than any of that. Researchers have confirmed what pharmacists in hot climates have known practically for years: GLP-1 medications — Ozempic and its cousins, now taken by millions — suppress thirst signals alongside appetite. In summer heat, that combination is genuinely dangerous. The body's early warning system for dehydration is blunted precisely when dehydration risk peaks. Heat exhaustion, heat stroke, hospitalisation. Not a theoretical risk. A real one.
I thought about this walking back through Valletta in the early afternoon last week, the limestone radiating heat at a frequency that feels almost personal. Malta in June is not the Red Sea wellness resort version of warmth. It is serious heat, the kind that asks something of you. If you are on a GLP-1, the ask becomes louder and you may not hear it.
The fix is not sophisticated. It requires no biometric ring, no functional medicine consultation, no Red Sea retreat. It requires drinking water on a schedule rather than waiting for thirst, because thirst, on these medications, may arrive late or not at all. Set a reminder. Carry a bottle. Treat hydration as medication, because in this context, it effectively is.
The body keeps its own schedule. The least we can do is show up for it, especially in the heat.
Tomorrow: set a hydration reminder on your phone for every two hours — not when you feel thirsty, but before.
