(WXYZ) — Metro Detroit is waking up to the lowest temperatures in two years. Sub-zero conditions make for a dangerous winter outside and indoors.
If you're heading outside, be sure to bundle up with multiple layers, and professionals say being inside requires the same amount of care.
"You want your outer layers to be able to repel moisture to keep you dry, "Dr. Jason Vieder from Henry Ford Hospital said.
Vieder recommends at least three layers of clothing to keep you warm if you do go outside.
Hospitals are bracing for frostbite victims, but indoors can present dangers as well when trying to stay warm.
Fire Captain Dennis Hunter warns of carbon monoxide poisoning, a silent killer.
"Your gas range, some people use their stove for heat, that can also produce CO in your home," Hunter said. "When it gets cold like this, the first thing a person wants to do is get warm. Unfortunately, carbon monoxide poising is the most common type of poisoning we see and it's most often unintentional."
Vieder said common symptoms can feel like the flu.
HVAC experts say you also want to make sure your exhaust vents don't become blocked by snow. Keep them clear to avoid CO buildup in your house, and if your home is constantly cold, you have safe alternatives.
"If you don't have heat in your home the city has warming centers," he said.
Finally, make sure you have a CO detector, which the City of Detroit has available for all residents.
