Why does rainy weather affect people's mood?

Let me tell you something. What's it like to walk on the road with a hat with a big brim? Very depressing. With less light, it is heavy on the head, and so is the umbrella. On rainy days, you can compare the dark clouds to a big hat or an umbrella. Covering the head, affecting the line of sight and light, will also be depressed. Depression is the fuse of bad mood. When people are depressed, they are obviously easy to get angry or lose. You must have had the experience of sunny weather and the sun standing high. At that time, many things would look on the bright side. The gray world and various factors will affect your judgment and your hormone secretion, so you will think bad. It's simple. As long as you are a strong-willed person, these external factors have little influence. If you are weak inside, your influence will be greater. I suggest you find a strong and optimistic friend of the opposite sex, which can adjust your personality and make you mature and strong.
