What Is Heat Stroke? A Complete Guide
Heat stroke is the most severe heat-related illness, and it kills more people in the United States each year than tornadoes and hurricanes combined. It is also one of the most preventable, because almost every case starts with milder warning signs that are easy to dismiss in the moment.
This is a long but practical guide. It covers what heat stroke actually is, how it differs from heat exhaustion, the warning signs in adults and children, and what to do in the first ten minutes after recognizing it.
