Why does cold weather make people depressed?

Hello, personally, I think this question can be understood as follows:

1. As the weather gets colder and colder, people's metabolism will slow down, and in winter, people don't like to move. If they are quiet for a long time, they will feel depressed and a little depressed.

The weather is getting colder and colder until winter comes, and what people can do gradually moves indoors. Indoor activities themselves can make people feel depressed, and then feel depressed;

3. After the season enters winter, the movement of air particles slows down and the weather conditions become worse. In the dark and gloomy weather, people just feel depressed and depressed.

I hope my answer can help you.
