Frostbite is a
condition that cause your body tissue to freeze in
extremely cold temperatures. You've probably heard
stories of someone getting it. However, do you know
how you get it? What happens to you when you get it?
How does it form?
Frostbite is caused by being
outside too long in freezing cold temperatures. Ice
crystals form around your blood vessels and skin (body
tissue). Blood flow is stopped in the frostbitten
Frostbite most commonly forms on
the ears, nose, chin, fingers, and toes, because they
are the most exposed and cold air can surround them
more easily. Symptoms of frostbite include reddening
of the skin, or spots and patches. The skin then
becomes pale or turns grayish-blue and a stinging or
prickly feeling occurs. Numbness can develop next. The
next stage of frostbite is blistering, itching, and
skin peeling or swelling. In extreme cases, you may
lose the tissue in the frostbitten areas. This is most
likely to happen to fingers, toes, and ears.
You can prevent frostbite by
wearing several layers of clothing (gloves, hats,
jackets, etc.) and don't stay outside too long, or
find a shelter that protects you from wind and cold.
You can also prevent frostbite by replacing wet
clothing with dry clothing. When having frostbite you
should treat it by trying to restore the circulation.
You do this by running cool water over the area and
warming it slowly.
