Where I stayed
About 60% of the Iceland natives we have seen have white blond hair (more white than blond), 100% of them have extremely pale skin and they all appear to be very lean.
Skin color has always fascinated me as a biology teacher. Melanin is one of the main pigments that give a person color. The more melanin a person has, generally the darker the person's skin, hair, and eyes. Melanin provides protection from the sun, but it also lowers the skin’s ability to use the sun to manufacture Vitamin D.
It makes sense that the people here would be so pale skinned. Even though there are seasons when the sun almost never sets (like now) the sun’s rays hit with low intensity. There is no danger here of getting a sunburn. Pale skin maximizes one’s ability to manufacture Vitamin D.
