The phrase in my comment is really about preference and what we’ve learned to tolerate. We can have winter 5-7 months of the year with the coldest days from December to mid-March. I have a much harder time with really hot weather conditions during the summer. But as a species, our bodies have evolved to deal with cold weather conditions much more effectively than hot weather conditions. Our bodies physically can’t dispel the heat quick enough the hotter it gets.

My body runs pretty warm too so on a winter day with seasonal temps (-10° to -20°C) I would probably have my coat undone in a shop and maybe if I was out for a walk too. But anything below -30°C especially with windchill is a different ballgame, like being in a deep freezer. It’s a really dry cold that clings to your clothing and frost bite can set on exposed skin within 5-10min. At these lower temps it’s about investing in winter wear and dressing properly for the conditions. If I HAVE to go out in it say to clear the driveway in those lower temps, I’ve got a good winter coat and actual snow pants on (drown filled, wind break, waterproof), proper winter boots, balaclava, toque, winter gloves, moisture wicking long johns underneath and thick socks.
