Protect
yourself from the cold bite of winter (Cold
Facts about Frostbite and Hypothermia)
Frostbite usually affects the fingers, toes, heels, hands, nose and feet.
It happens only in subfreezing temperatures. Numb, red and slightly swollen
skin characterize superficial frostbite. It may look gray or yellowish,
but becomes red and flaky after thawing.
Blisters appear with deep frostbite, and skin may become cold waxy, pale
and hard. Pain may lessen and disappear.
Stumbling, mumbling and fumbling can be signs that motor skills, speech
and decision-making abilities are impaired. As hypothermia progresses,
victims may seem confused or deny that they are cold. Unconsciousness
and death can follow.
Frostbite is limb threatening; hypothermia is life threatening. When the
core body temperature is threatened, blood is redirected to the internal
vital organs. This can put a person’s limbs at greater risk of frostbite,
but it can be life-saving.
Children and the elderly as well as people with injuries, chronic illnesses
and those who have taken medication.
Don’t rub your hands together. Rubbing will cause more tissue damage.
Instead, submerge frostbitten parts in water that is not quite hot to
the touch (104 to 108 F). A person might want to take aspirin –
thawing will be painful and aspiring helps prevent blood clotting. Seek
Medical attention.
Remove wet clothing. Add insulation beneath and around the victim. Cover
the person’s head. Don’t place a victim close to a heat source.
Adding heat stops shivering (the body’s mechanism to create heat)
in the mild hypothermic victim. Seek medical attention for those with
severe hypothermia. These victims need to be re-warmed in a medical facility.
