Some activities such as snow shoveling and walking through heavy wet snow can strain the heart enough to cause a heart attack.
Gillian Wong with the Heart and Stroke Foundation says, when it’s cold outside, blood vessels constrict and then when you add a strenuous activity, the risk of a heart attack goes up.
She says a heart attack can even happen to people who think they are healthy and we should know the warning signs.
Those are chest discomfort, sweating, upper body discomfort, light-headedness, shortness of breath or nausea.
Wong says it’s a good idea to do some warm up exercises before getting started and then some cool down activities as well.
