Common practices adopted during the hot summer months in the United Arab Emirates may be misguided, according to medical experts who warn that several widespread beliefs could increase risks of dehydration, heat exhaustion, and heat stroke. Health professionals emphasize the importance of replacing myths with evidence-based precautions to better protect residents during extreme heat.

Dr. Rayan Mohammed, a general practitioner at Valeo Health, highlighted the misconception that people should wait until they feel thirsty to drink water. She explained that thirst is a delayed signal of dehydration, especially among older adults, children, and those spending extended periods in air-conditioned environments where fluid loss is less apparent. Contrary to popular belief, Mohammed noted there is no medical evidence that drinking ice-cold water in high temperatures is harmful; cold water remains safe for most individuals.

Another common misunderstanding surrounds the use of sunscreen. While sunscreen is effective at blocking ultraviolet radiation and preventing sunburn, it does not guard against heat-related illnesses such as heat exhaustion or heat stroke, Mohammed added.

Emergency medicine physician Dr. Wayne Martini Jr. from the Mayo Clinic cautioned against relying too heavily on fans for cooling during extreme heat conditions. He explained that when air temperatures rise above approximately 35°C, fans can blow hot air across the skin, potentially increasing heat exposure rather than reducing it. Martini Jr. recommended combining fans with air conditioning, seeking shade, taking cool showers, or applying damp cloths for more effective cooling. He also advised against taking salt tablets after heavy sweating, noting that excessive salt intake without adequate water consumption can worsen dehydration. Instead, he suggested balanced electrolyte drinks and normal meals to restore hydration.

Martini Jr. stressed the urgency of recognizing heat stroke, characterized by symptoms such as confusion, slurred speech, agitation, stumbling, or collapse. Immediate cooling measures and prompt emergency care are essential. Recommended actions include pouring cool or cold water over the body, placing ice packs on the neck, armpits, and groin, and using fans or misting with water. For healthy young individuals who collapse during strenuous activity, cold-water immersion may be appropriate.

Dr. Abeir Ali, a general practitioner at Prime Hospital, underscored that heat-related illnesses can affect anyone, not just those working outdoors or engaged in physical exertion. Vulnerable groups such as children, older adults, and people with chronic medical conditions may exhibit fewer typical warning signs, making prevention even more important. Ali reiterated the critical safety advice never to leave children, elderly individuals, or pets unattended in parked vehicles, as internal temperatures can escalate rapidly during UAE summers.

Internal medicine consultant Dr. Unni Rajasekharan Nair from Medicare Royal Specialty Hospital challenged the belief that sugary soft drinks or energy beverages provide effective hydration. He attributed the persistence of such myths to their reinforcement through social circles and social media, despite the increased risk they pose during extreme heat. Nair encouraged simple but proven preventive measures: drinking water regularly throughout the day, wearing lightweight and breathable clothing, avoiding prolonged exposure to direct sunlight during peak midday hours, and taking breaks in cool environments when working or exercising outdoors.

Healthcare professionals agree that prevention remains far safer and more effective than treating heat illnesses after symptoms develop. Staying hydrated before the onset of thirst, understanding the limitations of common cooling methods, and recognizing early signs of heat-related conditions can be crucial for coping with the UAE’s challenging summer climate.
