Researchers from University of Montreal, Canada, found that days following heavy snowfall carry a higher risk of heart attack in men and this is mainly because of them carrying out labourious activities like shoveling snow. "Up to now, there was a theoretical risk that snow shoveling can increase heart attack at a population level. With this study, we are now more certain that snowfall is linked with heart attack in individuals," said Professor Nathalie Auger of University of Montreal.
So what is the cause of these heart problems? "Snow shoveling is very challenging for the heart, and you should be aware that shoveling can be a real strain, especially if you overdo it," said Professor Nathalie Auger. Most of these activities are carried out by men thereby putting them at a higher risk, regardless of age, cardiovascular risk factors and other health conditions.
During heavy snowfalls, cautionary measures are taken to prevent automobile accidents and such, but not activities like shoveling. The researchers therefore shared that their findings should be a reminder that people need to be concerned about potential cardiovascular risks, particularly older men and those who are not at the best of cardiovascular health.
There are some questions regarding the study, however, it is important to note that since the oxygen supply is lesser in colder climates, over-exerting yourself could take a toll on your heart. The study published in the Canadian Medical Association Journal.
