How much does the weather affect people's mood?

In fact, the weather is only a potential factor to induce emotional changes. If you are in a bad mood because of the weather change, I think the main reason is that your current situation makes you feel bad, but the weather change makes you feel bad. In other words, something happened the day before. The weather made your body and senses feel the same. You unconsciously thought of the bad things that happened that day, so you were in a bad mood.
