Many people assume that we yawn because our bodies are trying to get rid of extra carbon dioxide and to take in more oxygen. According to this theory, when people are bored or tired, they breathe more slowly. As breathing slows down, less oxygen makes it to the lungs. As carbon dioxide builds up in the blood, a message to the brain results in signals back to the lungs saying, "Take a deep breath," and a yawn is produced.
