"“Our body’s ability to control temperature or thermo-regulate does involve blood circulation. In the cold, the small blood vessels on the surface of our body get smaller to keep warm blood deeper inside. In the heat, they dilate to release heat from the body. If you have been in a warm climate for a long time and return to a cold one, it may take a little longer for your circulation to adjust.”"
I used to live in a place where 50 degrees always felt miserable. Then I lived in the upper midwest for a while (and I'm about to again). And when you reach the end of winter and that first 50-degree day... you could literally go out in shorts and a t-shirt and feel wonderful.
So, I could see a long-time team member for a cold-weather team being a little "looser" at winter games there.
