BROOKE KATZ: All right. Just looking at the temperature isn't enough this time around. Doctors say people must consider the windchill factor if you have to go outside. In today's "Ones for Wellness," it can take minutes before you get frostbite. Fingers, toes, earlobes, and the tip of the nose are typically most susceptible to frostbite. Dr. Bill Fales, an emergency physician, says that's because the body is trying to conserve heat, keeping the blood flowing to internal organs, leaving the extremities with less flow.
DR. BILL FALES: When people start to shiver, that's a sign to get out of the cold and get in and get warm.
BROOKE KATZ: Doctors say if you start to shiver, that means your body temperature is dropping fast, which could lead to hypothermia. While hypothermia can be deadly, frostbite can be very painful. Here's a chart showing how long you can be exposed to certain temperatures before resulting in a frostbite. Dr. Rachel Polinski says it can take less than 30 minutes for children to get frostbitten.
DR. RACHEL POLINSKI: Lay her up. Make sure all those extremities are covered. Yeah, make sure you're able to get back inside if you're experiencing any numbness, tingling. If you like you're not moving your digits anymore because they feel like they're swollen, that's early signs of frostbite.
