The dangers become all too clear when there is a disaster like last winter's ice storm in Eastern Canada, and when unprepared people become stranded or fall into cold water. Hypothermia, sometimes called exposure, occurs when the body can no longer produce more heat than it is losing. It's important for Canadians to know what leads to hypothermia, says Therien. Wind, wet and cold are the key factors. Wind can chill the body as air moves over it.
Most body heat is lost through the head.
Wear layered clothing. Proper layers will allow warm air to stay trapped but do not trap perspiration next to the skin. Protect your feet and hands. Wear loose waterproof boots. If the boots have felt liners, carry an extra pair to replace damp ones.
