The UAE’s extreme summer temperatures make heat-related illness a genuine and serious risk for children. Temperatures regularly exceed 40°C between June and September, and even well-prepared families can find themselves in a situation where a child is showing signs of heat distress. Knowing the difference between heat exhaustion and heat stroke and knowing exactly what to do can save your child’s life. Why Children Are More Vulnerable Than Adults Children’s bodies are less efficient at regulating temperature than adult bodies. They have a higher surface-area-to-body-mass ratio, sweat less efficiently, and are often too absorbed in play to notice or communicate overheating. Infants and toddlers are the most vulnerable of all; they cannot remove clothing, seek shade, or ask for water on their own. In the UAE, risk situations include prolonged outdoor play during peak heat hours (11 am–4 pm), being left in a parked car even briefly, inadequate fluid intake during outdoor activity, and sporting events held in the heat without adequate shade or rest breaks. Heat Exhaustion: Signs and What to Do Heat exhaustion is the warning stage, serious but manageable if acted upon quickly. Signs of heat exhaustion in children: Heavy sweating despite the heat. Cool, pale, or clammy skin. Weakness, fatigue, or muscle cramps. Headache, dizziness, or nausea. A rapid but weak pulse. The child may feel faint but remains conscious and responsive. What to do: Move the child to a cool, shaded, or air-conditioned environment immediately. Remove excess clothing. Apply cool (not ice-cold) wet cloths to the skin, especially the neck, armpits, and groin. Offer small, frequent sips of cool water or an oral rehydration solution. Do not force fluids if the child is vomiting. Our article on the best ways to keep kids hydrated this summer is a helpful reference for understanding fluid needs during the UAE summer. Monitor the child closely. If symptoms do not begin to improve within 30 minutes, or if the child loses consciousness or stops responding, escalate immediately to emergency services; this is now a potential heat stroke situation. Heat Stroke: Signs and What to Do Heat stroke is a medical emergency. Unlike heat exhaustion, the body’s cooling system has failed. Without immediate action, heat stroke can cause organ damage, brain injury, or death. Signs of heat stroke in children: Body temperature above 39.4°C (103°F) that rises rapidly. Hot, red, dry skin, the child has stopped sweating despite extreme heat. Confusion, disorientation, or unusual behaviour. Rapid, strong pulse. Vomiting. Seizures. Loss of consciousness or unresponsiveness. What to do — call emergency services (999 in the UAE) immediately. While waiting for help, move the child to a cool environment without delay. Begin rapid cooling, apply ice packs or cold wet cloths to the neck, armpits, and groin simultaneously. If available, immerse the child in cool water (not an ice bath for infants). Fan the child continuously. Do not give fluids to an unconscious or semi-conscious child. Do not leave the child alone. Heat stroke requires hospital treatment. Intravenous fluids, monitoring, and in some cases, intensive care may be needed depending on severity.

In the UAE context, the most effective protective measures include keeping children indoors during peak heat hours (11 am–4 pm) from May through September. Ensure children are well-hydrated before, during, and after any outdoor activity. Thirst is a late sign of dehydration. Dress children in light, loose, light-coloured clothing and apply sunscreen. Never leave a child in a parked car, even for a minute. For newborns and very young infants, the risks are especially acute. Our Healthy Newborn Clinic provides comprehensive guidance for new parents on keeping infants safe through the UAE’s extreme seasonal conditions. You may also find our article on how to protect your baby’s skin from the sun a useful companion read for the summer months. For older children involved in sports or outdoor activities, understanding the signs of dehydration early is essential. Our article on signs of dehydration in infants covers the physiological signs to watch for across age groups. When to See a Paediatrician After a Heat-Related Episode Even if a child recovers from heat exhaustion at home, a follow-up paediatric consultation is strongly recommended. Heat-related episodes can cause subtle effects on the kidneys, electrolyte balance, and cardiovascular system that may not be immediately apparent. A Paediatric Health and Wellness review following any significant heat episode gives you the reassurance that recovery is complete. Understanding the difference between heat exhaustion and heat stroke is knowledge every parent in the UAE needs, not just in summer, but year-round. When in doubt, act fast, cool the child, and call for help. Your paediatrician is always there to support you before and after.
