Heed warnings
Some days are simply too cold to safely enjoy the great outdoors. Be aware of any weather advisories when you are planning to spend time outdoors in winter, and follow all recommendations regarding your safety.
The National Weather Service issues wind chill advisories, wind chill watches and wind chill warnings when conditions warrant. A wind chill advisory is issued when cold and windy conditions are expected, and these conditions could result in hypothermia or frostbite in people who do not take proper precautions. Like with severe thunderstorm and tornado watches and warnings, a wind chill watch means dangerously cold air and wind chill values are possible, while a wind chill warning means the dangerously cold air and wind chill values are occurring or expected to occur.
The potential dangers of spending time outdoors during a wind chill warning include hypothermia, which is a low body temperature, and frostbite. Both can occur with prolonged exposure to extreme cold, according to the Centers for Disease Control and Prevention.
Long exposures to very cold temperatures force your body to use stored energy to stay warm. When this happens, your body temperature begins to drop. Signs of hypothermia include confusion, memory loss, exhaustion, drowsiness, slurred speech, fumbling hands and shivering, according to the CDC. In babies, signs can also include skin that is bright red and cold and very low energy.
If you suspect hypothermia, take the person’s temperature immediately if possible. If it is below 95 degrees, seek immediate medical attention. If medical help is not immediately available, move the person to a warm place indoors or to a sheltered spot, remove any wet clothing and warm the center of their body — the head, neck, chest and abdomen — with blankets (heated if possible), towels or clothing.
Frostbite occurs when the skin freezes. It is most common on our bodies’ extremities, including fingers, toes, ears, noses, cheeks and chins, the CDC reports. Signs of frostbite include white or grayish-yellow skin, skin that feels waxy or unusually firm and numbness.
In severe cases, frostbite can cause permanent damage and even result in amputation of the affected areas. If you suspect frostbite, get yourself into a warm room as soon as possible and place the affected areas in warm but not hot water, the CDC advises. Do not walk on feet or toes if you suspect frostbite because this can worsen damage. In addition, do not use direct heat from a stove or fireplace, heating pads or heat lamps to warm the skin, and do not rub or massage the affected areas.
