Cold Weather Health Dangers
Hypothermia occurs when the body’s temperature falls below normal and impacts brain function. Warning signs include extreme shivering, confusion, slurred speech, slow breathing and a weak pulse, drowsiness or low energy, and bright red, cold skin. If you notice any of these signs and the body temperature is lower than normal, begin warming the person with warm blankets, beverages and shelter. Seek medical attention.
Frostbite is the actual freezing of body parts and is usually indicated by numbness and white, blue or greyish skin. If left untreated, frostbite can lead to the loss of fingers, toes or other affected areas. Seek immediate medical attention for cases of frostbite and gradually warm the affected areas while seeking this assistance.
