How to Prevent
Freezing weather is more than uncomfortable --
it's dangerous. Jack Frost doesn't nip -- he bites. Temperatures below
freezing can lead to frostbite and hypothermia if people do not take
proper precautions. If you have to be outside during
below freezing temperatures, here are some tips to keep you safe
What is frostbite?
Frostbite occurs when skin tissue and blood
vessels are damaged from exposure to the cold. Blood pulls away
from the skin, toward the core of the body. It is the body's way
of trying to keep warm. Frostbite sometimes presents itself with
white blanched skin. You shouldn't rub it. You should get out of
the cold, and let the affected area warm up on its own.
If the area blisters, doesn't return to
normal color or is painful, victims should seek immediate medical
treatment. Areas with the least fat, like fingers, toes, earlobes
and the nose are most at risk for frostbite.
Its wise also to be wary of hypothermia -- a
potentially deadly condition that occurs when the body temperature
drops below 97 degrees Fahrenheit. If you are shivering in
reaction to the cold, your body is still working. Shivering stops
at 92 degrees Fahrenheit. At that point, victims have an altered
state of consciousness and get sleepy.
Victims should get out of the cold and let
the body gradually warm up on its own. Give victims something hot
to drink -- but absolutely no alcohol and do not let them smoke.
Alcohol and tobacco work as dilators, opening the body's 'windows'
to let heat out.
The best way to prevent both frostbite and
hypothermia is to stay out of the cold for long periods of time
and dress in layers. A little known fact: cotton has no thermal
value of any kind. The best layers are LYCRAŽ and silk because
they bounce heat back to the body. Wool is perfect.
As another rule of thumb, adults should dress
their children with one more layer than they themselves wear and
everyone should wear a hat.
