Please help spread the word by checking on your neighbors. Not only do we want people to stay as warm as possible - we want our community to recognize the signs of hypothermia so our first responders can help. Per the CDC, elderly populations, and those with children and pets can be most at risk in cold conditions. While hypothermia is most likely in extreme cold, it can occur even above 40 degrees if a person becomes too chilled. Low body temperature affects the brain, making victims unable to think clearly or move well.
