What’s the biggest myth about staying warm during cold-weather treks?

I think the biggest myth is that exertion always equals warmth. sure, moving generates heat, but if you're sweating buckets, that moisture can quickly become your enemy when you stop or the wind picks up. Then suddenly, that exertion is working against you, pulling heat away faster than you can replace it via movement alone.

So many people think they just need to "push through" and keep moving, but learning to properly layer and regulate your temperature is key. Sometimes, the best thing you can do is slow down, take a break to add a layer before you get cold and damp, or even vent a bit to prevent overheating in the first place. Staying dry is more vital than pushing hard. It's a much more active process than just "move faster to stay warm." What do you all think?
