FROM THE NATIONAL WEATHER SERVICE
Frostbite can happen in minutes, especially on the extremities such as fingers, toes, nose, and ears, but can affect any area of exposed skin. If you suspect frostbite, immediately move inside to a heated location and begin warming the affected areas using warm water or body heat. Do not use hot water or radiant heat such as a fireplace since affected areas can be easily burned. Seek medical attention for severe frostbite.
- First-degree: Ice crystals are forming on your skin.
- Second-degree: Skin begins to feel warm even though it is not yet defrosted.
- Third-degree: Skin turns red, pale or white.
- Fourth-degree: Pain lasts for more than a few hours and skin may develop dark blue or black. See a doctor immediately if these symptoms arise. Gangrene is a real threat.
Get indoors as quickly as possible. Until you can get indoors:
- Don't rub or massage cold body parts.
- Put your hands in your armpits.
- Hold onto another person or animal.
- Drink warm liquids.
- Put on extra layers of clothes, blankets, etc.
- Remove rings, watches, and anything other tight jewelry or related items.
- Don't walk on a frostbitten foot. You could cause more damage.
- Get in a warm, NOT hot, bath and wrap your face and ears in a moist, warm, NOT hot, towel.
- Don't get near a hot stove or heater or use a heating pad, hot water bottle, or a hair dryer. You may burn yourself before feeling returns.
- Frostbitten skin will become red and swollen and feel like it's on fire. You may develop blisters. Don't break the blisters. It could cause scarring and infection.
- If your skin turns blue or gray, is very swollen, blistered or feels hard and numb even under the surface, go to a hospital as soon as possible.
–Beware of Hypothermia
When your body temperature sinks below 96°F, you have hypothermia, a serious health hazard that occurs when body temperature is lowered too much. Get medical attention immediately. Move the victim inside to a heated location and begin warming the center of the body first. If the person is unconscious, administer CPR.
- Dress in layers.
- Wrap up well when going outside in the cold.
- Avoid breezes and drafts indoors.
- Eat nutritious food and wear warm clothes to ward off winter chill.
- Wear a warm hat in the winter.
- Eat hot foods and drink warm drinks several times during the day.
- If you live alone, ask a family member of neighbor to check on you daily or have a camera installed that a family member can view on their computer.
- Ask your doctor if any medicine you're taking increases your risk of hypothermia. Drugs that may cause a problem include barbiturates, benzodiazepines, chlorpromazine, reserpine, and tricyclic antidepressants.
