SIOUX CITY (KTIV) - Extreme heat will linger for the next week with highs topping 100 degrees on several days. So, it’s important to find ways to stay cool.

The experts at MercyOne Siouxland Medical Center encourage you to stay hydrated, find an air-conditioned space, or some shade, and be aware of your surroundings. And watch for symptoms of heat-related illness, like dizziness and nausea.

Health officials say it’s important to get out of the heat if you see those symptoms. It’s also important to know the difference between heat exhaustion and heat stroke.

“If you get too much you go past heat exhaustion into heat stroke. Heat stroke is a true emergency, basically, your body’s unable now to cope with the heat and dissipate it and its protective mechanisms are basically shut off,” said Barbara Fitzgerald of MercyOne Siouxland Medical Center.

Officials also stress the importance of making sure that your water intake is keeping up with the amount of liquid lost.
