The expansion of travel routes toward Phan Rang and former Ninh Thuan brings travelers to vast, pristine sand dunes and magnificent coastal roads. However, the unique climate of this coastal area is semi-arid, characterized by very high UV indices and intense sunlight lasting throughout the day. Continuous outdoor activities, long-distance motorbike rides, or walking to take photos on Nam Cuong Sand Dunes under high temperatures without adequate hydration can easily lead to heat exhaustion or heatstroke. This is a medical emergency that can lead to severe consequences if not recognized and treated promptly.
Recognizing the Body's Early Warning Signs
Heatstroke does not happen out of nowhere; it is preceded by warning signs from the body's thermoregulation system. When the body begins to overheat, you may experience symptoms such as a flushed face, hot and dry skin (inability to sweat), a throbbing headache, dizziness, lightheadedness, nausea, and a rapid, pounding heartbeat.
If the condition worsens while travelers continue to move under the harsh sun, the victim may begin slurring speech, staggering or losing balance, feeling confused or disoriented, and ultimately fainting completely. Early recognition of these signs in companions, especially vulnerable individuals such as young children and the elderly, enables timely intervention to prevent the situation from deteriorating.
A Scientific On-Site Cooling Protocol
As soon as you notice a group member showing signs of heat illness, the first step is to immediately remove them from the scorching sun and move them to sit or lie down in a cool, shaded, well-ventilated area or an air-conditioned room. Loosen tight clothing and remove excess gear such as helmets and heavy outer jackets to help the body cool down more easily.
Cool the victim down by applying cool, damp towels to areas where major blood vessels run close to the skin, such as the neck, armpits, and groin, to accelerate body temperature reduction. If the victim is fully conscious and not nauseated, encourage them to sip water slowly, prioritizing mineral-rich fluids, oral rehydration solutions (ORS), or light salted lemonade. Never pour water into the mouth of someone who is semi-conscious, as this poses a severe choking and aspiration risk. If symptoms do not improve after 15–20 minutes of first aid, or if the victim experiences seizures or a high fever above 39°C, call for emergency medical assistance immediately to transfer them to the nearest healthcare facility.
Quick Checklist:
-
Schedule visits to sand dunes or outdoor historical sites during early morning hours or after 16:00 in the afternoon.
-
Replenish fluids with plain water or electrolyte solutions every 20 minutes without waiting until you feel thirsty.
-
Always wear a wide-brimmed hat, sunglasses, and a lightweight UV-protective jacket when outdoors.
-
Rest in the shade immediately if you experience headaches, dizziness, or a sudden spike in heart rate.
-
Never self-administer standard fever-reducing medications (such as Paracetamol) to treat sun-induced heatstroke.
