Winter weather can put an added strain on the heart. If you are not used to regular exercise, activities such as shoveling snow or pushing a car can put a physical strain on your body, and in some case, can lead to a heart attack or can make other medical conditions worse.

If you go outside to shovel snow, do a few stretching exercises to warm up your body. Make sure to take frequent breaks, change out of wet clothes if necessary, and drink plenty of fluids.
