Why the Gulf summer dehydrates you in ways you do not notice
Dehydration in the UAE has a specific mechanism. Inland, in places like Al Ain or the desert edges of Dubai and Sharjah, summer humidity can drop low enough that sweat evaporates the instant it forms — you lose litres without ever feeling wet, which removes the body's most obvious warning signal. On the coast, the opposite problem: humidity in August can sit above 80 per cent, evaporation stalls, your cooling system fails, and you sweat even harder trying to compensate. Both routes end in the same place — significant water and electrolyte loss — but neither feels like the thirst you learned to recognise in a milder climate.
Air conditioning adds a second, quieter drain. Conditioned air is dried as it is cooled, so twelve hours a day in an office, car and apartment means twelve hours of accelerated respiratory water loss. Layer on the realities of UAE life — long-haul flights through DXB and AUH, Ramadan fasting compressing all fluid intake into a few night hours, weekend brunches, outdoor work between June and September — and you get the demand pattern local providers actually see: a summer spike, a Ramadan-evening spike, and a steady baseline of travellers and athletes.
