Dr. Wang Mingxuan
Early warning signs of heatstroke include headache, dizziness, thirst, sweating, limb weakness, fatigue, difficulty concentrating, and abnormal motor function—occurring in a hot environment—with normal or slightly elevated body temperature. In mild heatstroke, in addition to the above symptoms, body temperature rises above 38°C, accompanied by facial flushing, profuse sweating, and hot, dry skin. If these symptoms occur, outdoor activities should be minimized—especially work performed under high-temperature conditions. In cases of severe heatstroke, immediate transfer from the hot, sun-exposed area to a cool, well-ventilated environment is essential.
