Use fireplaces, wood stoves, or other combustion heaters only if they are properly vented to the outside.
Do not burn paper in a fireplace, because paper burns hot and could spark an out-of-control fire. And do not place a space heater within 3 feet of anything that may catch on fire, such as drapes, furniture, or bedding.
If you are going outdoors to shovel snow, know the stance. Shovel with your legs, lifting from your knees and upper legs as you shovel. Don't use your back, it can lead to strains. And take breaks. Cold weather puts an extra strain on the heart.
If you have heart problems or high blood pressure, talk to your doctor about shoveling snow or performing other hard work in the cold.
Dress warmly. Layer your clothing with sweaters, vests and jackets, to avoid hypothermia. And wear thick gloves to avoid frostbite.
Watch the ice. According to the Centers for Disease Control and Prevention, many cold-weather injuries result from falls on ice-covered sidewalks, steps, driveways, and porches. Keep them ice free by using rock salt or another chemical de-icing compound.
