First Aid: Cold Exposure
Intense cold can freeze the water in the body's cells (frostbite). This can result in the loss of parts of your fingers, toes, or ears, for example. Also, exposure to cold may cause the body's overall temperature to drop (hypothermia). The result can be death.
Step 1. Raise body temperature
In case of frostbite, wrap the area in a soft, loose cloth and seek medical care right away. If medical care is not nearby, hold the affected area under warm, but not scalding, water until normal skin color returns. Don't soak affected area for prolonged time. Don`t cause additional tissue damage by rubbing the area affected by frostbite. Only try to rewarm the area if you are able to keep the person out of the cold. Warming and then refreezing will worsen the damage from frostbite.
In case of hypothermia, put the victim in a sleeping bag or wrap him or her in dry blankets. Be sure to remove any wet clothing first.
Step 2. Give warm liquids
When to seek medical help
Seek medical help right away if any of the following is true:
The person's fingers, toes, nose, or ears are numb and don't quickly regain feeling when warmed.
The affected body part looks yellow-white or patchy blue.
Call 911 , or get medical care right away if the victim has any of the following:
Reassure the person and don't leave him or her alone.
Keep the person as warm and dry as possible. Don't be alarmed if the person begins to shiver. Shivering is the body's way of generating heat.
Treat for shock or do rescue breathing or CPR, if needed.
