Heatstroke Signs: Doctor Warns of 6 Critical Alerts Beyond Fatigue

Physicians are urging the public to recognize the serious signs of heatstroke, emphasizing that it's not always a sudden collapse but can manifest as early symptoms like dizziness, headache, nausea, and fatigue. Dr. Dai Xiaofu, president of Wenshin Clinic in Taoyuan, shared a personal experience of feeling unwell with dizziness and nausea while accompanying her child outdoors, realizing she had mild heatstroke.

Heatstroke doesn't always involve sudden collapse; dizziness, headache, nausea, and fatigue can be early warning signs.

Dr. Dai explained that common early warning signs include dizziness, headache, nausea, facial redness, tiredness, excessive sweating, and sudden weakness. She advised that adults, often preoccupied with children or waiting in lines, may overlook their own well-being until discomfort sets in. The key is to stop, move to a cool place, loosen clothing, and rehydrate gradually.

When you feel unwell, stop and rest in a cool place. Don't just think 'it'll be fine in a moment.'

For mild discomfort, plain water is usually sufficient. Electrolyte drinks are recommended for prolonged activity or heavy sweating. However, Dr. Dai stressed that severe symptoms such as confusion, persistent vomiting, high body temperature, muscle cramps, or skin that is hot and dry with little sweating necessitate immediate medical attention. The symptom of hot, dry skin, she noted, is particularly dangerous as it indicates the body's cooling system is failing.

Skin that is hot and dry with little sweating is not a sign of recovery, but may indicate the body's heat dissipation function is failing.
