KENNEWICK, Wash.-These low temperatures can make ordinary activities dangerous.
Most doctors agree dealing with snow and ice without wearing gloves can lead to frost bite.
There are several degrees of the condition, but brushing off your car probably won't cause the most serious effects.
Dr. John Matheson says other liquids like alcohol or gasoline are more dangerous.
"They evaporate rapidly and as they evaporate they cool. their freezing point is lower than zero so they can be in liquid form below the freezing point of water."
Doctors also warn of hypothermia. It can be fatal if severe enough.
