Monday's extreme cold should hopefully be the worst of the weather for the week, but anyone spending any time outside should be wary of frostbite.
If you have to spend any time outside, use layers and try to cover as much of your face as you can. If you notice a pale color to your skin or any tingling or numbness, go inside immediately and begin to gradually warm up. Be sure to know the difference between frostbite, which typically affects your extremities, and hypothermia, which affects your core body temperature.
"When your core body temperature starts to drop, that is something that needs to be warmed up very slowly, because if your core temperature drops too far down, that will result in [your] organs can actually shut down, which could lead to death," said Lynelle Diers of Wapello County Public Health.
Diers said your fingers and toes are the parts most susceptible to frostbite and it doesn't take very long when the temperatures are this cold.
While the initial symptoms of frostbite can be treated by warmth, if you notice any severe discoloration or blisters, see your medical provider.
