"Never accept numbness," says University of Manitoba researcher Gordon Giesbrecht, AKA Professor Popsicle, about being cold. Dr. Giesbrecht describes how to recognize when you are at risk of frostbite, and throws in a helpful tip on preventing frostbite on your hands. (HINT: Use your armpits.)
Dr. Giesbrecht studies human responses to exercise/work in extreme environments. He has conducted hundreds of cold water immersion studies that have provided valuable information about cold stress physiology and pre-hospital care for human hypothermia.
