A period of extreme cold has arrived in the North. While NWT winters in the past have regularly reached temperatures in the low -30’s and below, this season has been uncharacteristically warm.
The more mild winter season may have left some Northern residents less prepared to deal with the harsher temperatures we’re seeing now. A few recent days have even seen extreme cold warnings issued by Environment Canada, and warnings of frostbite.
Frostbite is damage to body tissue caused by extreme cold, and can cause a loss of feeling and a white or pale appearance in extremities, such as fingers, toes, ear lobes or the tip of the nose.
Frostbite can be avoided simply by dressing properly for the weather. Wearing several layers of lightweight clothing can help, as trapped air in between the layers can help to keep the body insulated. If doing strenuous outdoor activities, avoid wearing cotton. Once wet, cotton takes a long time to dry and will sap your heat.
Wearing a hat can also help, as 40% of the body’s heat can be lost from the head. Keeping the mouth covered also prevents cold air from getting inside the body, and in the lungs. Keep mittens and gloves tight around the wrist whenever possible.
Survival kits for cars are also recommended. Make sure they are filled with dry, warm clothes, boots, blankets, flashlight with extra batteries, candy bars or cereal bars. Always carry a charged cell phone and tell others of your travel plans.
