Stay Safe and take precautions during Winter Weather

Tennessee Department of HealthNashville, TN – Winter won’t officially arrive until December 21st, but parts of Tennessee are already experiencing cold, hazardous weather.

The Department of Health is reminding Tennesseans to take common-sense precautions to stay safe and healthy during cold weather.

“We know school children may look forward to snow days, but we want to remind Tennesseans that winter weather with temperatures below freezing can be dangerous or even deadly,” said Health Commissioner Susan R. Cooper, MSN, RN. “We want people to take the needed precautions to protect themselves from extreme cold, and we urge Tennesseans to check on loved ones who may be more susceptible to the low temperatures. Families should review and update their plans for transportation and child care when schools are dismissed for snow.”

When exposed to cold temperatures, the human body begins to lose heat faster than it can produce it. Prolonged exposure to cold will eventually use up the body’s stored energy. The result is hypothermia, or abnormally low body temperature. Hypothermia affects the brain, making the victim unable to think clearly or move well. Hypothermia is particularly dangerous because a person may not know it is happening and may not be able to do anything about it. Hypothermia is most likely to occur at very cold temperatures, but can occur even at temperatures above 40° F if a person becomes chilled from rain, sweat or submersion in cold water.

Frostbite is an injury to the body caused by freezing, and results in a loss of feeling and color in affected areas. It most often affects the nose, ears, cheeks, chin, fingers or toes. Frostbite can permanently damage the body, and severe cases can lead to amputation. The risk of frostbite is increased in people with reduced blood circulation and among people who are not dressed properly for extremely cold temperatures.

Cold weather also puts an extra strain on the heart. If you have heart disease or high blood pressure, follow your doctor’s advice about shoveling snow, chopping wood or performing other hard work in the cold. Otherwise, if you have to do tiring outdoor chores, dress warmly and work slowly. Remember your body is already working hard just to stay warm, so don’t overdo it.

The following tips will help keep you and your family safe and healthy during extremely cold weather:

  • Try to stay indoors when weather is extremely cold, especially if winds are high. If you must go outdoors, make trips outside as brief as possible.
  • When going outside during very cold weather, adults and children should wear:
    • a hat
    • a scarf or knit mask to cover face and mouth sleeves that are snug at the wrist
    • mittens (they’re warmer than gloves)
    • a water-resistant coat and boots
    • several layers of loose-fitting clothing
  • Be sure the outer layer of your clothing is tightly woven to reduce body heat loss caused by wind. Wind-resistant fabrics are best. Wool, silk or polypropylene inner layers of clothing will hold more body heat than cotton.
  • Stay dry, as wet clothing chills the body rapidly. Excess sweating will increase heat loss, so remove extra layers of clothing whenever you feel too warm.
  • Avoid getting gasoline or alcohol on your skin while fueling and deicing your car or using a snow blower. These substances in contact with the skin greatly increase heat loss from the body.
  • Do not ignore shivering. It’s an important first sign that the body is losing heat. Persistent shivering is a signal to return indoors.
  • Avoid alcohol and caffeinated beverages, which cause your body to lose heat more rapidly. Alcohol can also impair judgment and lead to ignoring signs of cold stress on the body.

Walking on ice is also extremely dangerous. Many cold weather injuries result from falls on ice-covered sidewalks, steps, driveways and porches. Keep your steps and walkways as free of ice as possible by using rock salt or another chemical deicing compound. Sand or even cat litter may also be used on walkways to reduce the risk of slipping.

The State of Tennessee has many resources available to help keep you safe and healthy during winter weather.
