"How Long Does It Take to Get Frostbite"

Obviously, the colder the weather, the greater the likelihood of contracting frostbite. But you can't entirely rely on what the mercury says. Your standard household thermometer doesn't pick up on wind chill, a meteorological phenomenon that can turn a glorious winter wonderland into a frozen wasteland with a simple gust of wind. To anyone who's never experienced wind chill, imagine being slapped in the face multiple times. Not only does it feel unpleasant, but wind chill speeds up body heat loss wherever skin is exposed, and thus contributes to an increased frostbite risk. That's why winter weather reports often involve two temperatures, the one with and the one without wind chill. For example, it might be -10°C (14°F) outside, but if it's windy enough, it could feel more like -20°C (-4°F).
