Because most body heat is lost through the head, it is important to wear a hat. Keeping your skin exposure to a minimum will help prevent frostbite. Watch for signs of hypothermia, which is particularly threatening to the very young and elderly. Hypothermia is an internal body temperature drop during which the body can no longer generate as much heat as is being lost. Hypothermia can be fatal.
Symptoms are confusion, slurred speech, stiff muscles, or uncontrollable shivering.
If symptoms occur, get medical assistance immediately. If you're traveling, check weather and road conditions before you leave. You can monitor conditions along the way with a Weatheradio, a portable VHF-FM radio that broadcasts weather information and instant weather warnings from Environment Canada. They could be lifesavers if you get stranded. Losing power in your home during a storm is another concern, especially for rural residents who may rely on electricity for heat.
