Why is the colder the place, the better and whiter the skin?

The colder the place, the better the skin. The reasons are as follows: (1) Short sunshine time makes the skin less prone to sunburn; (2) In cold places, the air is generally humid, and the skin is not easy to lack moisture; (3) It is easy to snow in cold places, and white snowflakes are contagious. The same is true for those who are close enough to be red. (4) In cold places, the nights are longer. People sleep for a long time and get enough rest. As the saying goes, sleeping beauty.
