Snow shoveling is usually a kind of exercise for people who are fit and healthy. It utilizes the muscles of the arms, back, and legs and increases the heart rate. A one hour shoveling can burn about 300 calories. But shoveling under low temperature could be potentially harmful to the heart because-
In the cold temperature, our blood vessels get narrow and that is why there is a decreased amount of oxygen that reaches the heart.
Shoveling or using a snowblower can also lead to a sudden increase in blood pressure as well as the heart rate that can cause clot formation and dislodge.
