Symptoms progress in three stages. Stage I (mild): dizziness, lightheadedness, muscle cramps. Stage II (moderate): headache, nausea, fatigue, profuse sweating. Stage III (severe): altered consciousness, seizures, core temperature above 40°C — a life-threatening emergency. Be especially cautious during sudden heatwaves and after consecutive tropical nights, as the body hasn&rsquo;t yet acclimated.</p>/en/clinic-info/summer-2026-heatstroke-guide-first-aid-and-when-to-see-a-doctor/Sat, 27 Jun 2026 10:00:00 +0900/en/clinic-info/summer-2026-heatstroke-guide-first-aid-and-when-to-see-a-doctor/<img src="/img/thumbnail/summer-heatstroke-first-aid-emergency-guide-2026-en.png" alt="Featured image of post Summer 2026 Heatstroke Guide: First Aid and When to See a Doctor" /><p>The Japan Meteorological Agency forecasts another record-hot summer in 2026. Heatstroke is largely preventable with the right knowledge, yet thousands of people are rushed to hospitals each year. This guide covers how to recognize heatstroke symptoms, perform proper first aid, and decide when to seek medical care.</p> <h2 id="recognizing-heatstroke-severity">Recognizing Heatstroke Severity </h2><p>Heatstroke is classified into three severity levels. Mild (Grade I) involves dizziness, fainting, and muscle cramps. At this stage, resting in a cool place and drinking fluids with salt usually brings recovery. Moderate (Grade II) adds headache, nausea, fatigue, and body temperature above 38°C — medical attention is recommended. Severe (Grade III) includes altered consciousness, convulsions, and hyperthermia above 40°C. This is life-threatening and requires an immediate ambulance. Correctly assessing symptoms in yourself or others is the first step to appropriate action.</p>
