We all like to laugh. People wonder why things are funny. There are three big ideas about this. They talk about different reasons we find things funny. One idea is called the "relief theory." It says laughing makes us feel less stressed. When we feel scared or very worried, laughing makes us feel better. Laughing can also help us say things we are usually afraid to say. For example, when we are tickled, it makes us laugh. This is because we feel a little stressed before the tickle. Laughter lets out this stress. A very old thinker, named Aristotle, thought that laughing helps us feel better after we are sad or scared.
