Outdoor Work Heatstroke Warning: Doctors Alert on Emergency Symptoms

According to a report by Central News Agency, a 60-year-old man surnamed Zhang in Changhua County experienced weakness and confusion after spending nearly two hours working outdoors in a field. Initially thought to be fatigue, his condition worsened rapidly, with symptoms including disorientation, flushed skin, and cessation of sweating, leading to hospitalization and a diagnosis of heatstroke.

Changhua Show Chwan Memorial Hospital issued a press release highlighting the case. Dr. Li Yu-ching, Director of the Department of Family Medicine, warned that heatstroke is a life-threatening emergency. When the body’s thermoregulatory system fails and core temperature exceeds 40°C, multiple organs—including the brain, heart, liver, and kidneys—can suffer damage. Without prompt treatment, the mortality rate can exceed 30%.

Dr. Li explained that in heatstroke, the body stops sweating due to failed cooling mechanisms, leading to dry, hot, red skin, high fever, rapid pulse, confusion, and even coma. These are not signs of simple heat exhaustion but indicate a medical emergency requiring immediate hospitalization.

High-risk groups include adults over 65, infants and young children, individuals with chronic illnesses, and outdoor workers such as laborers and farmers. Risk increases in hot, humid environments, especially when sweating heavily without adequate hydration or wearing non-breathable clothing. Patients taking diuretics, cardiovascular medications, or psychiatric drugs should also be especially cautious.

If someone shows signs of heatstroke, immediately move them to a cool, shaded, and well-ventilated area. Loosen or remove excess clothing, apply wet cloths or ice packs to the neck, armpits, and groin, and fan the body to promote cooling. If the person is conscious and not vomiting, offer small sips of cool water or diluted electrolyte drinks. Call emergency services (119) or transport the person to a hospital immediately to secure the critical window for treatment.
