' The sharp distinction between heat- and cold-related deaths is because low temperatures cause more problems for the body's cardiovascular and respiratory systems, [the study] added.'

Researchers say their findings back up the theory that wider nostrils developed in populations living in warm, humid conditions, while populations living in high latitudes, such as northern Europe, developed narrower nostrils as an adaptation to the chilly, dry conditions: https://archive.ph/3PQL0#selection-1101.0-1101.273



White skin helps to synthesize Vitamin D at a higher rate than other skin tones which also helps prevent rickets at a higher rate in White populations compared to populations living in the same conditions: https://web.archive.org/web/20210927185813/https://www.theglobeandmail.com/life/changes-in-arctic-diet-put-inuit-at-risk-for-rickets/article687556/


Skin type V individuals have, by definition, significant constitutive pigmentation that gives their skin its brown colour. The melanin pigment protects the underlying skin against damage from UVR. In reducing the UVR in this way it also reduces the vitamin D synthesis due to the same UVR. Thus, theory suggests, and our in vivo studies have shown [7,16] that skin type V individuals need more UVR (achieved naturally by more sun exposure) to make the same amount of vitamin D in skin as white Caucasians who lack their constitutive pigmentation.
