WIND CHILL CHART

- What is wind chill temperature?
- The wind chill temperature is how cold people and animals feel
when outside. Wind chill is based on the rate of heat loss from exposed
skin caused by wind and cold. As the wind increases, it draws heat
from the body, driving down skin temperature and eventually the internal
body temperature. Therefore, the wind makes it FEEL much colder.
If the temperature is 0 degrees Fahrenheit and the wind is blowing
at 15 mph, the wind chill is -19 degrees Fahrenheit. At this wind
chill temperature, exposed skin can freeze in 30 minutes.
- Can wind chill
impact my car's radiator or exposed water pipe?
- The only effect wind
chill has on inanimate objects, such as car radiators and water
pipes, is to shorten the amount of time for the object to cool.
The inanimate object will not cool below the actual air temperature.
For example, if the temperature outside is -5 degrees Fahrenheit
and the wind chill temperature is -31 degrees Fahrenheit, then
your car's radiator will not drop lower than -5 degrees Fahrenheit.
- What is FROSTBITE?
- You have frostbite when
your body tissue freezes. The most susceptible parts of the body
are fingers, toes, ear lobes, or the tip of the nose. Symptoms
include a loss of feeling in the extremity and a white or pale
appearance. Get Medical attention immediately for frostbite. The
area should be SLOWLY re-warmed.
- What is HYPOTHERMIA?
- Hypothermia occurs when
body temperature falls below 95 degrees Fahrenheit. Determine this
by taking your temperature. Warning signs include uncontrollable
shivering, memory loss, disorientation, incoherence, slurred speech,
drowsiness, and exhaustion. Get medical attention immediately.
If you can't get help quickly, begin warming the body SLOWLY. Warm
the body core first, NOT the extremities. Warming extremities first
drives the cold blood to the heart and can cause the body temperature
to drop further--which may lead to heart failure. Get the person
into dry clothing and wrap in a warm blanket covering the head
and neck. Do not give the person alcohol, drugs, coffee, or any
HOT beverage or food. WARM broth and food is better. About 20%
of cold related deaths occur in the home. Young children under
the age of two and the elderly, those more than 60 years of age,
are most susceptible to hypothermia. Hypothermia can set in over
a period of time. Keep the thermostat above 69 degrees Fahrenheit,
wear warm clothing, eat food for warmth, and drink plenty of water
(or fluids other than alcohol) to keep hydrated. NOTE: Alcohol
will lower your body temperature.
- Tips on How to
Dress during cold weather
- The best way to avoid
hypothermia and frostbite is to stay warm and dry indoors. When
you must go outside, dress appropriately. Wear several layers of
loose-fitting, lightweight, warm clothing. Trapped air between
the layers will insulate you. Remove layers to avoid sweating and
subsequent chill. Outer garments should be tightly woven, water
repellent, and hooded. Wear a hat, because half of your body heat
can be lost from your head. Cover your mouth to protect your lungs
from extreme cold. Mittens, snug at the wrist, are better than
gloves. Try to stay dry and out of the wind.
- Avoid Overexertion
- Your heart is already
working overtime in cold weather. The strain from the cold and
the hard labor of shoveling heavy snow, walking through drifts
or pushing a car may cause a heart attack. Sweating from overexertion
could lead to a chill and hypothermia.
