Extreme heat can kill or cause long-term health problems – but for many unendurable temperatures are the new normal
The impact of extreme heat on the human body is not unlike what happens when a car overheats. Failure starts in one or two systems, and eventually it takes over the whole engine until the car stops.
That’s according to Mike McGeehin, environmental health epidemiologist at the Centers for Disease Control and Prevention. “When the body can no longer cool itself it immediately impacts the circulatory system. The heart, the kidneys, and the body become more and more heated and eventually our cognitive abilities begin to desert us – and that’s when people begin fainting, eventually going into a coma and dying.”
