The top story on the CNN website reads as follows:
A bone-chilling Arctic cold wave with temperatures as low as 42 below zero shut down schools for thousands of youngsters Monday, halted some Amtrak service and put car batteries on the disabled list from the northern Plains across the Great Lakes.
What are the symptoms of frostbite?
Frostbite happens when the skin and the tissues underneath it actually freeze. Winds and cold temperatures are the culprits, as well as not dressing properly for the cold outdoors. Frostbite affects children more than adults, as children lose more heat through their skin. The first symptom of frostbite, called frostnip, is the least severe form, and usually leaves the skin feeling numb and looking white. Cheeks, noses, and ears are most frequently frostnipped. When the skin thaws or warms, the affected area will become red and painful. With even more severe frostbite, the skin may appear white and feel very numb, meaning that the tissue has started to freeze. Very severe frostbite may cause blisters and damage to structures, such as tendons, muscles, and bone.
