Fighting Off Frostbite
Maybe you live in a state that experiences a cold, blustery winter or perhaps
you’re planning a vacation to a cooler climate. If so, frostbite is a
condition that shouldn’t be taken lightly.
When you’re exposed to severe cold, the possibility exists for you to
suffer from frostbite—the freezing of skin or tissues. The areas of the
body most susceptible to frostbite are the fingers, toes, hands, feet, ears,
nose and cheeks.
Frostbite occurs when blood vessels in the skin constrict. Because the blood
flow has decreased, the fluid in and around the skin cells develops ice crystals.
This condition can be characterized into two categories—superficial
frostbite and deep frostbite. With superficial frostbite, gray or yellow patches
appear on the affected areas while the skin remains soft and pliable. However,
after thawing, the skin looks red and flaky.
When dealing with deep frostbite, the skin looks waxy and feels solid. As
it thaws, it may turn blue or purple and large blisters may appear.
Certain measures can be taken in order to prevent this potentially dangerous
condition. It’s vital to wear loose-fitting layers when you must venture
outside in severely cold weather, and remember to cover vulnerable areas of
the body like the nose and ears. Also, it’s important to maintain fluid
levels by consuming warm, non-alcoholic, caffeine-free drinks regularly.
Another tip for preventing frostbite is to stay dry. According to the National
Safety Council, wet clothing loses 90 percent of its insulating value.
The complications of frostbite can be severe: gangrene; amputation of dead
or infected tissue, especially fingers, toes, nose or ears; and cardiac arrest
if the frostbite occurs with total body hypothermia when the body’s temperature
drops below 95 degrees Fahrenheit.
While wintertime brings with it moments for having snowball fights and making
snowmen and angels, it also brings the elements that cause cold-related injuries
like frostbite. Using common sense and following these suggested tips can help
you have a fun, but safe winter season.
If you think you have frostbite, physicians recommend the following:
- Go to a warm location.
- Seek medical attention for treatment as quickly as possible.
- Elevate the affected areas, particularly if swelling occurs.
- Rest the injured areas. For instance, if your feet have been frostbitten,
don’t walk around.
- Leave blisters intact.
- Do not rub the affected areas to warm them. Instead, place the areas
in luke-warm water, warm blankets or against warm body parts.
- Do not expose the affected areas to direct heat – fire, stove,
radiator, etc.
- Do not put ointments or bandages on the affected areas. If fingers
or toes are affected, place sterile gauze between them to absorb moisture and
keep them from sticking together.
- Do not use alcohol or nicotine because it affects the blood flow.
