Homunculus-argument: The main difference between the weather being uncomfortably cold, and the weather being uncomfortably hot, is that the things you can do in the cold to warm yourself up (hot food/beverage, blankets, cuddles, nice clothes like sweaters, thick scarves and snazzy jackets, getting exercise) are very pleasant and very effective, and the things you can do in the heat to cool yourself down don’t do shit.

Noucetnerd: I’ve been trying to explain this to folks. It’s easier to go from a state of low energy to high energy than vice versa. That’s why for the majority of human history there’s been more ways to stay warm than beat the heat, and the ways to resist the cold are FAR simpler. Light a fire, layer up, stand close to others. If you wanna cool down with no wind and no water? Saddle up, bucko, you’re in for a wild ride.
