Does the weather affect people's height?

Have a certain impact. I saw it on TV. For example, Chongqing, Wuhan and Shanghai.

Chongqing people are shorter than Han people. Wuhan people are shorter than Shanghai people (both are taller).

The sunshine time in Chongqing (the foggy city) is less than that in Wuhan, and the sunshine time in Wuhan is less than that in Shanghai.

But climate is not the decisive factor. The decisive factor is genes. But the weather does have some objective factors. Sunbathing can promote calcium absorption. Everything grows on the sun. Watching the house and raising rabbits on TV. In winter, because of the lack of sunlight, rabbits have to be irradiated with fluorescent lights for several hours. Otherwise the rabbit will get rickets.
