Eliza,
We who live in areas that have real winters have clothing which keeps us toasty warm on cold days. Animal skins are very effective for keeping in body heat. Covering all exposed skin is a must on very cold days, too, especially when the wind is blowing.

I suspect that we also have internal body thermostats that run more efficiently than those of people in warmer climates. I can't stand much heat. After a lengthy cold spell, it warmed up here today to just above freezing. When we went for a Sunday drive to enjoy the sunshine, I passed a young man who was walking along the side of the highway wearing jeans, sports shoes and a t-shirt.
