Winter in the northeast can be enjoyable with all
the wintertime activities. But if you're going to be outside for a while you
have to be careful. This post is on
frostbite and hypothermia.
During the winter we not only have to protect
ourselves from the cold but also the wind.
Temperature and wind combine to produce something called the windchill
temperature index.
The wind chill factor makes us feel colder than the
air temperature really is. This is due to the interaction of air temperature
and wind increases the heat loss from your body.. when the air temperature
is low wind chill can quickly freeze exposed skin.
Here's a chart that shows the windchill feel like
temperature, when we combine air temperature and wind speed.
What happens if you stay outside for too long?
First, the parts of your body that are further away from your torso (such as
your face, fingers, and toes) will begin to freeze. This is called frostbite. Frostbite causes a loss of feeling and a
white or pale appearance in extremities, such as fingers, toes, ear lobes, or
the tip of the nose.
Here's a image that shows the effects of frostbite.
If symptoms are detected, get medical help
immediately! If you must wait for help, slowly rewarm affected areas. However,
if the person is also showing signs of hypothermia, warm the body core before
the extremities.
Hypothermia is a serious medical emergency that
occurs when the body’s temperature drops below 95° F (35° C). Your body loses heat
faster than it can produce it, and your blood will begin to thicken, making it
hard for your heart to pump blood. Without the proper amount of body heat the
heart, lungs, and other organs cannot work correctly. Hypothermia is very dangerous
and can eventually lead to death.
Dress for both temperature and wind. You must keep
your face covered on a windy cold day.
before going out into conditions that can cause frostbite and
hypothermia, you should dress in several layers of loose fitting, light weight
clothing. The other layer of clothing
should be hooded and water and wind repellent.
Remember mittens offer better protection from the cold than gloves.
