Heat Exhaustion and Heatstroke: Silent Killers in the Summer Sun
As global temperatures climb due to climate change, extreme heat is becoming more frequent ? and more dangerous. The World Meteorological Organization reports the past decade has brought record-breaking temperatures and a sharp rise in heat-related illnesses. Two of the most serious are heat exhaustion and heatstroke, which can be fatal if not recognized and treated promptly.
Heat exhaustion typically results from fluid loss and prolonged exposure to the sun. Symptoms include headache, flushed face, heavy sweating, fatigue, nausea, vomiting, dizziness, and fainting. The skin may feel cool or clammy, and muscle cramps or heat rash may appear. Treatment involves moving to a shaded area, drinking water or sports drinks, and cooling the body with wet towels.
Heatstroke is a medical emergency that can quickly devolve into serious complications. It occurs when the body’s temperature regulation fails, causing the internal temperature to rise above 40 degrees Celsius. Signs include confusion, severe headache, dizziness, loss of consciousness, seizures, vomiting, and dangerously low blood pressure.
Experts warn that older adults, children, and people with chronic illnesses face the highest risk. Staying hydrated, avoiding midday sun, and recognizing early warning signs are crucial steps in preventing tragedy during increasingly intense summer heat.
