Believe it or not, cooking up a storm on a chilly day is a great way to warm your home. Cooking with the oven serves two purposes - feeding your family and staying warm at the same time.
Leave your bathroom door open after you shower, let all of that steamy air out to warm the other areas of your home. Or if you plan on staying in one area, close doors to the other rooms, that will keep the heat concentrated in that area.
Prepare warm drinks, maybe even a hot toddy - they really will make you feel warm.
Move around - stay active whether you run around with the kids, take brisk walks or hit the gym - exercising is a great way to keep warm and healthy!
