Do you know how weather affects our lives? Well, IT affects where we go, what we do and what we wear. And IT also affects how we feel and behave. IT is a big part of our lives. We often use weather language to describe how we feel. For example, if we are feeling ill, we say we are under the weather. If we are feeling stressed and busy, we can say that we are snowed under. We use bad weather to describe a bad mood and good weather to describe a good mood. And that is not all. The weather can even change the way we feel. For example, sunlight helps our body to produce vitamin d. This vitamin can improve our mood, but some parts of the world get little sunlight in winter, so people can feel unusually sad. Then, however, when IT is hot and Sunny, some people may get angry easily too. Scientists are still studying how the weather changes the way people feel and behave. These days, many of us spend the less time outside. Getting no fresh air or sunlight, and spending too much time inside can make us feel down. IT is very important to go outside once in a while, whatever the weather, rain or shine.
