Hydration in the Local Climate: How Much and What to Drink in Dubai

As the mercury routinely crosses 40°C across Dubai each summer, hydration has become a frontline priority for residents braving morning jogs along Marina Walk, volleyball matches on JBR Beach, and even quick strolls outside. Local clinics have reported a steady increase in cases of dehydration and heat stress since early June, as the city’s outdoor activity calendar heats up.

Staying Hydrated in Dubai’s Heat

This growing concern is not just about comfort-serious health risks are on the line, particularly during the Dubai Fitness Challenge in October, when thousands commit to 30 minutes of activity daily for 30 days. Between sand-scorching afternoons and warm, humid evenings, the risk of fluid loss accelerates. In such extreme weather, even the World Health Organization has flagged the UAE’s high rates of heat exhaustion incidents compared to European cities with milder summers.

In popular fitness spots such as the 7-kilometre-long Marina Walk and across state-of-the-art facilities like Gym Nation in Bur Dubai, demand for chilled bottled water and electrolyte beverages spikes each year. Spar supermarkets along Jumeirah Beach Residence regularly clear out their water stocks before noon on weekends, according to staff. Meanwhile, fitness trainers at local boutique studios, such as The Platform Studios in Dubai Marina, warn clients to monitor their hydration levels with apps like Hydro Coach, especially during Ramadan or summer fasts, when dehydration risks intensify.

How Much-and What-Should You Drink?

International guidelines recommend an average adult should consume at least 2 to 3 litres of fluids daily, but in Dubai’s intense heat, UAE-based medical centres such as Mediclinic City Hospital advise active individuals to increase intake up to 4 litres-roughly eight standard 500ml bottles-on extremely hot days. Stepping outside for just an hour of moderate activity can lead to the loss of one litre or more of sweat. For comparison, a two-litre bottle of locally branded Al Ain water is priced at AED 3.5 at most supermarkets. Rehydration drinks containing electrolytes, such as Pocari Sweat, are widely available for AED 8-10 per bottle and are recommended after high-intensity exercise or prolonged sun exposure, especially for runners training for events like the Dubai Marathon.

Despite the popularity of sweetened or carbonated drinks, sports nutritionists at Emirates Sports Medicine Centre advise moderation, noting that sugary beverages provide a short energy burst but may exacerbate fluid loss in the long run. Instead, coconut water (averaging AED 12 per 330ml in Dubai Marina cafés) and homemade lemon-mint water are popular among local fitness buffs for their refreshing taste and natural minerals.

Making Hydration a Habit: Practical Steps

To maintain consistent fluid intake, experts recommend keeping a refillable bottle handy; water fountains along Kite Beach and Safa Park provide chilled drinking water for free. Wear light, moisture-wicking fabrics when outdoors, and avoid exercise during peak heat (12pm-4pm). The Dubai Health Authority’s online portal offers a hydration calculator and a list of clinics that provide tailored advice for athletes, children, and the elderly.

Ultimately, with the next major wave of outdoor fitness events coming up-like Dubai Run scheduled for November-hydration is more than a summer survival tip, it’s a year-round necessity. Regular reminders from friends, fitness apps and even local radio announcements are helping the city stay cool and safe under the relentless sun.
