How much should you really drink in a UAE summer?
Thirst is a late signal. Here's a sane way to think about water when it's 42°C outside — without turning it into a science project.

There's no single number that fits everyone. What you need depends on how hot it is, how long you're out in it, how hard you're moving, and how much you sweat — which varies person to person. So instead of a magic figure, here's a way to think about it.
Thirst lags behind loss.
By the time you feel thirsty, you've usually already lost more than you'd like. In a hot climate that gap matters more, because you're losing fluid quietly all day — not just when you're obviously sweating. The fix isn't to drink frantically; it's to drink steadily, before you're parched.
What pushes your needs up here.
Four things stack up in the Gulf: high temperature, long hours outside, the dry pull of constant air-conditioning, and exercise. Any one of them lifts how much you should be drinking. Put several together — a midday round of golf, say — and the total climbs fast.
Where electrolytes fit (and where they don't).
For a short walk or a normal air-conditioned day, plain water is doing the job — you don't need anything added. It's the long, hot, sweaty stretches where electrolytes earn their place: you're losing minerals as well as fluid, and water alone only replaces one of them. That's the bottle SALT is built for.
This is general guidance, not medical advice. If you're pregnant, on a sodium-restricted diet, or managing a health condition, your doctor is the right person to set your numbers.
A simple rule of thumb.
Drink steadily across the day rather than waiting until you are parched at the end of it. On the long hot ones, reach for one SALT sachet in 750 ml and sip it through the session — not all at once.
