terminal illness related to cold climate?

Setting: a fantasy world, but in a land that would be like near the North Pole if it were Earth. Time-wise, probably equivalent to the 16th or 17th centuries.

Searched for diseases in cold climates, but mostly got a lot of information about the common cold.  Also went through most of the illnesses to order tag and didn't find exactly what I'm looking for.

My question is, are there any terminal illnesses affected by, caused by or exacerbated by a very cold climate?

I have a female character, probably in her late 30s, early 40s, whom I want to die after struggling with a long illness.  I *could* have it be something generic like pneumonia or something like that, but for the sake of another character's belief that the cold land killed her, I'd kinda like it to be something he could realistically blame on the land.  The length of the illness is negotiable, though I'd like it to err on the side of longer rather than something that kills in just a few weeks say.  Months would be better.

ETA - Thanks everyone for the ideas. I think I'm going with something lung-related like cor pulmonale. :)
