According to his team of researchers, the heart rate and blood pressure increases more in healthy young men when they are shovelling snow compared to when they are running on a treadmill. This, combined with the cold air, causes arteries to constrict and decreases blood supply, which can lead to unforeseen heart problems.
Franklin believes that shovelling snow is so taxing that people who are overweight, smoke or over the age of 55 shouldn't be doing it at all. "People at greatest risk are those who are habitually sedentary with known or suspected coronary disease, who go out once a year to clear snow" he added.
So there you have it. To snowballs say yes. To snowmen say yes. To shovelling or any difficult manual labour, as always, say no and stay indoors with your feet up.Explore more on these topics:
