Heatstroke is a life-threatening medical emergency that requires immediate treatment, according to CNN, citing emergency physician Dr. Leana Wen.
As extreme summer temperatures push more than 100,000 Americans to emergency departments each year, experts are urging people to recognize the warning signs early.
Anyone showing these symptoms should receive emergency medical care immediately. While waiting for help, bystanders should move the person to a cool place and use cold water or ice packs to lower body temperature.
The report said milder conditions such as heat exhaustion and heat cramps should also be treated quickly with rest, hydration and cooling measures.
Older adults, young children, people with chronic illnesses, outdoor workers and those without access to air conditioning face the highest risk during prolonged periods of extreme heat, according to Dr. Wen.
