The Lawrence-Douglas County Health Department encourages residents to exercise caution when outdoors during cold temperatures.
Director of Clinic Services Kim Ens, a registered nurse, said serious health problems could result from prolonged exposure to the cold. The most common problems are frostbite and hypothermia. “Winter weather can be extremely dangerous, especially for infants and older adults,” Ens said. Infants lose body heat more easily than adults; additionally, infants can’t make enough body heat by shivering. Older adults often make less body heat because of a slower metabolism and less physical activity.
It’s important to consider the Wind Chill Index, which is the temperature your body feels when the air temperature is combined with the wind speed. When there are high winds, serious weather-related health problems are more likely, even when temperatures are only cool.
Here are some tips to keep safe this winter season:
When exposed to cold temperatures, your body will lose heat faster than it can be produced. The result is hypothermia, or abnormally low body temperature. Body temperature that is too low affects the brain, making the victim unable to think clearly or move well. This makes hypothermia particularly dangerous because a person may not know it is happening and won’t be able to do anything about it.
Warnings signs of hypothermia:
If you notice any of these signs, take the person’s temperature. If it is below 95 degrees, the situation is an emergency.
Frostbite is an injury to the body that is caused by freezing. Frostbite causes 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.
At the first signs of redness or pain in any skin area, get out of the cold or protect any exposed skin. Any of the following signs may indicate frostbite:
A victim is often unaware of frostbite until someone else points it out because the frozen tissues are numb. If you detect symptoms of frostbite, seek medical care.
