It does make sense that the Human body adapts to what's asked of it, altering blood flow, perhaps even on a long-term basis (by increasing or decreasing the amount of skin capilaries), to suit the cooling needs or lack thereoff. I think much of climatic adaption, ignoring items such as nose shape and (of course) skin pigmentation, is acquired rather than genetic.
