Symptoms of heat stroke versus heat exhaustion

Dangerously high temperatures are about to reach the Chicago area, and experts are urging the public to recognize the symptoms of heat-related illness.

“The biggest problem, again, is the way our body normally dissipates heat to keep our temperature where it should be, through sweating and then the evaporation of that sweat from the body,” Lewis said, adding that with high temperatures and high humidity “what happens is “It's very difficult for our bodies to evaporate that heat or that sweat.”

“So we can't really cool ourselves down. And that's where we run into problems during these weather conditions,” he said.

Symptoms of heatstroke can include confusion, loss of consciousness, fever, dry skin, seizures, or high body temperature. Symptoms of heat exhaustion can include muscle cramps, headaches, dizziness, and more.
