Give you a few clues? It's not just acclimatization at work ~ it's a different way of responding to the need to retain core temperature AND have enough left over to save your life if need be.

Trick ~ next time it gets real cold and there's an ice storm, step outside and see if your bare hands HEAT UP and melt the ice.

Sa'ami do that. Others don't.

Lots of folks who are not "culturally" Sa'ami are actually "genetically" Sa'ami.

The Swedish and Finnish medical establishments study the Skolt and Inari intensely. They compare their performance to that of non-Sa'ami in the same occupations. This is part of a broad effort to identify specific genes with specific characteristics.

I read those reports regularly just to keep ahead of "problems".

I think mine do, but I’ll have to test that out. Many times I’ve heated up my much less tolerant wife with my bare hands out in cold weather. But we’re not talking extreme cold.
