The expansion of tourism towards Phan Rang, Ninh Thuan brings visitors to vast, pristine sand dunes and gorgeous coastal routes. However, the climate of this coastal region is semi-arid, characterized by a very high UV index and intense sunlight that lasts throughout the day. Continuous physical exertion outdoors, long-distance motorbiking, or walking to take photos on the Nam Cuong sand dunes under high temperatures without proper hydration can easily lead to heatstroke. This is a dangerous medical emergency that can leave serious consequences if not recognized and addressed in time.
Identifying early warning signs from the body
Heatstroke does not happen suddenly; there are always warning signs from the body's thermoregulation system. When the body begins to overload from the heat, you will experience symptoms such as: flushed face, hot and dry skin (inability to sweat), pounding headache, dizziness, lightheadedness, nausea, and a feeling of rapid heart palpitations.
If the situation worsens and the traveler continues to move under the harsh sun, the victim may exhibit slurred speech, unsteady walking, loss of balance, confusion, and eventually complete fainting. Early recognition of these signs in fellow travelers, especially for sensitive groups like young children and the elderly, will help families intervene to prevent the condition from worsening.
Scientific on-site cooling procedure
As soon as you detect a member of your group showing signs of heatstroke, the first step is to immediately move them away from the harsh sun and into a shaded, well-ventilated area or an air-conditioned room. Loosen their clothing and remove items such as helmets and thick outer jackets to allow the body to cool down easily.
Begin cooling the victim down by using a damp towel soaked in cool water, applying it to areas with large blood vessels such as the neck, armpits, and groin to accelerate the body temperature reduction process. If the victim is fully conscious and shows no signs of nausea, have them drink water in small sips, prioritizing mineral-replenishing drinks, electrolyte solutions (Oresol), or lightly salted lemonade. Absolutely do not force water into the mouth of someone who is semi-conscious, as it can easily cause choking and aspiration. If symptoms do not improve after 15-20 minutes of first aid, or if the victim shows signs of seizures or a high fever over $39^\circ\text{C}$, call an ambulance immediately to transport them to the nearest medical facility.
Quick checklist:
-
Schedule visits to sand dunes or outdoor historical sites for the early morning or after 4:00 PM.
-
Drink water or electrolyte solution every 20 minutes; do not wait until you feel thirsty.
-
Always equip yourself with a wide-brimmed hat, sunglasses, and a thin UV-protective jacket when going outdoors.
-
Rest in the shade immediately if you feel a headache, dizziness, or a sudden increase in heart rate.
-
Absolutely do not self-medicate with common fever reducers (such as Paracetamol) to treat heatstroke caused by intense sun exposure.
