When it's too hot you aren't always able to get cooler.
When it's too cold it is always possible to get warmer. If only in a small way.
In the middle of winter you can put on another layer, wear fuzzy socks, drink a nice warm drink, hell even just blow into your hands. But in the middle of summer sometimes you just have to suffer.
I fucking love winter and no one can take that from me
Read "To Build a Fire." I've been in places that cold, thankfully never lost in the woods. There are definitely places that you absolutely cannot get warmer no matter how many layers you put on.
Thankfully I now live in a place that it literally cannot get too hot or too cold.
Not with a thick internal shell of plaster or concrete and wooden or steel beams that are built to tolerance. I suppose if you built them with Medieval technology, it would. I'd build it with a super-Adobe style wall, which should be able to withstand a fairly decent earthquake. Probably not any higher than a 6 or 7 on the Richter scale.
Layers alone don't do the trick. You need to move to generate heat in the first place. Once it drops below -20/-25C, you can pretty much only be still if you're in a good sleeping bag.
Assuming we're talking about outdoors, that's not the case for me in my area. There's only so much layers can do. You have to limit exposure. Plus all those layers can be a chore. By comparison, while summer heat can be uncomfortable, it's rarely deadly and far easier to stay safe.
I beg to differ. I've literally lived outside in < -30C, over time, without much more equipment than my clothes, a hammock, and a gas burner to boil water.
You have a limit to exposure, of course, but it's not a limit you can't comfortably overcome with relatively simple equipment (read: layers).
This is very dependent on where you live, and to an extent how rich you are. If you live somewhere where it occasionally gets a bit hot but it often gets so cold you need to spend a lot on heating then you probably prefer summer. Vice versa for somewhere so hot you need to pay for air conditioning.
Or live in northern europe where it can be -30C in the winter and +30C in summer. Still prefer winter, -30 is fine with enough layers, +30 is fucking miserable.
