Answer 1

Physical activity warms you up. It can make a huge difference in keeping you warm.

I remember in the mid 00s, living in Anchorage, in the winter wearing a thick coat into an arcade, playing Dance Dance Revolution on hard mode for 30mins-1hr, and comfortably walking back to my car holding the coat instead of wearing it over my T-shirt, the cold air actually felt really nice.
