Frequently I have been asked, "how do you handle the extreme heat/cold of (name your place here)?" The response to both extremes is the same: appropriate clothes, indoor climate control (i.e. heating or air conditioning), good insulation, a well maintained automobile, plan and dress accordingly for going outdoors and if it is just too cold/hot you stay inside.
Time, whether it be in years or the gradual shift in seasons is a way to acclimate. Once you are acclimated the extremes are perceived to be more manageable/tolerable. Personal preference also influences your attitude and comfort level. I prefer hot to cold which is why I moved to Texas in the first place.
I believe that there is something special about the people that thrive in extreme weather climates for extended periods of time. Harsh weather builds up mental and physical toughness. For some people this toughness pushes them to look forward with anticipation to the extreme conditions. Regardless of the extreme, the preparation follows the same steps.
