People living in northern climes have grown accustomed to freezing weather, especially in recent weeks. But just how deadly is the icy grip of Old Man Winter?

According to the report, Cold weather, it’s often assumed, causes more deaths overall than hot weather. And the recent polar vortex that broke low-temperature records across North America provides some evidence: At least 21 deaths have been blamed on that cold-weather event.

But scientific research presents a more complex picture, and for a number of reasons, cold weather-related deaths have to be analyzed in a different way than deaths linked to hot weather.

Any weather extreme, whether hot or cold, is more likely to increase mortality, and both extremes can cause stress to a person’s cardiovascular system, according to experts.
