"(I've got) gloves. Scarf," said Dominique Stewart. But is that enough? "No, it's not. I need Eskimo clothes out here!"

"If you think you're immune because you're a Chicagoan, and not a lot of gentlemen walking around with hats nowadays. But keeping on a hat, gloves, scarf," said Dr. Ed Ward, Rush University Medical Center.
Staying inside is the best option, especially for senior citizens. Experts say seniors are especially susceptible to problems in the extreme cold.
"Seniors have gone through a lot of decades of cold weather. So they feel that they're capable of handling it. And a lot of times they're taken by surprise," said Joyce Gallagher, Chicago Department on Aging.
At least one death has been blamed on the cold. City officials are urging neighbors to look in on their elderly neighbors. If they notice they are having any problems, call 311 and the Department of Human Services can check on them.
