At the poles you use references like “sleeps,” because “nights” don’t make sense to a circadian rhythm of 24 hours (the polar night is 6 months long). The polar lands are in effect “deserts”, void of the sorts of things humans need to live healthy, fulfilling day-to-day existences. In a word "lonely."

So, sure, there is "polar" in that the poles are lonely and sometimes when people don't "get you" it can be lonely too--"polar," I guess makes sense in that vein. 

There's "polar" as desert but, also another aspect worth considering. That is polarities, of something, something, something, something, something, which then becomes anti-something, anti-something, ad infinitum, this idea of Arctic and Antarctic as simultaneously opposites and mirror images, twins separated at birth subconsciously competing, one with the other.
