WEATHER BASICS: Wind chill, weather alerts & safety tips
Posted: Nov 12, 2014 9:55 AM CDT | Updated: Jan 7, 2015 10:45 AM CDT
Winter storms cause more damage and kill more people every year in Wisconsin than tornadoes, lightning, and floods. Winter weather has many dangers, from snow and wind to extreme cold, ice, and fog. Prolonged exposure to extreme cold can cause frostbite or hypothermia (infants and the elderly are most susceptible). Below you'll find tips for winter safety whether you're indoors or outdoors, and how to recognize signs of frostbite and hypothermia.
Effects of the Cold
FrostbiteFrostbite is a severe reaction to cold exposure, and can cause permanently damage. Symptoms include a loss of feeling, and a white or pale appearance in fingers, toes, or nose and ear lobes.
Hypothermia
Hypothermia is a condition that occurs when the body temperature drops below 90 degrees Fahrenheit. Symptoms include uncontrollable shivering, slow speech, memory lapses, frequent stumbling, drowsiness, and exhaustion.
Treatment
If frostbite or hypothermia is suspected, begin warming the person slowly and seek immediate medical assistance.
Warm the person's trunk first. Use your own body heat to help. Arms and legs should be warmed last because stimulation of the limbs can drive cold blood toward the heart and lead to heart failure.
Put the person in dry clothing and wrap their entire body in a blanket.
Never give a frostbite or hypothermia victim something with caffeine (like coffee or tea) or alcohol. Caffeine is a stimulant and can make the heart beat faster, hastening the effects of the cold on the body. Alcohol is a depressant and can slow the heart, also hastening the ill effects of cold body temperatures.
Winter Safety Tips
FOR THE ELDERLY- As we get older, we're more sensitive to the cold
- Find a \"buddy\" to check on you daily, in person or by telephone
- Stay active. Sitting in one place can make you colder
- Ask a friend or relative to de-ice or shovel your walkways and porches to avoid a fall
WHEN INSIDE
- Use proper precautions when using alternate heating, such as a fireplace, wood stove, or electric heater, including proper ventilation and keeping flammables far away
- Eat. This helps your body produce its own heat.
- Avoid alcohol, which can make your body lose heat
- Close off unused rooms to conserve heat
- Wear loose-fitting, light-weight, warm clothing. Remove layers to avoid perspiring
WHEN OUTSIDE
- Wear loose-fitting, light-weight, warm clothing in several layers
- Wear a hat, particularly one that covers your ears
- Wear mittens, these are better than gloves because they keep the fingers close together
- Find shelter
- Try to stay dry and cover all exposed parts of your body
- Cover your mouth to protect your lungs from extreme cold
- Do not eat snow. It lowers your body temperature-- let it melt first.
