If you have to brave the outdoors in these sub-zero temperatures, health officials want you to be smart about it.
The Indiana Department of Health advises to wear a hat or a hood as most heat is lost through your head.
Wear layers of loose-fitting clothing, it helps if your sleeves are snug at the wrist, and mittens--they're warmer than gloves.
Keep in mind that babies and older adults are most vulnerable to the intense cold.
Be on the lookout for symptoms of hypothermia and frostbite. See a doctor immediately if you notice symptoms.

Symptoms of frostbite:
