Fun fact: cold acclimatization really is a thing. The body makes some adaptations when subjected to cold frequently.

As an extreme example: people involved with polar expeditions tend to sweat profusely when going indoors for the first time in weeks, after spending all day out in the cold and sleeping in tents.
