Scientists are trying to find out how things affect our feelings. How you feel is controlled by many things, such as your personality, the actions (行动) of others. Maybe you don’t know the weather can affect your feelings as well.
People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies make vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains and makes us feel happy. However, there are long dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad. To help the people in these countries feel better, scientists build special “sunrooms” for people to go there and get “sunlight” for an hour or two!
The weather can also affect people’s feelings in other ways. Hot weather can make people angry because they don’t feel comfortable. In the same way, rain can make people angry because people hate to be wet all over. As you can see, the weather can have an effect on the chemicals which control our brains and affect our feelings. Sadly, only the weather can change us, we cannot change the weather.
