"We got to take advantage of it, right? While we can. That is the Chicago motto. Take advantage of it while you can because you know what? In two months it's not going to be so pleasant," Ernie Brown said.

Some relief may be on the way in the form of cooler temperatures, but in the meantime experts are warning of the dangers of heat illnesses caused by the high temperatures and humidity.

If possible, stay in the air-conditioning and out of the sun.

But if you have to be outside, make sure you drink plenty of fluids and that you also check up on relatives and neighbors.
