Likewise, during a yawn the walls of the sinuses flex, and when combined with the wide opening of your gaping maw, together they draw large quantities of air in through the nasal cavities, mouth and sinus passages. Theories of Yawning There are three main theories as to why people yawn. Yawning increases blood oxygen levels Because it draws in large quantities of air, many people have reasonably theorized that yawning purpose is to draw in more oxygen and exhale CO2; this tenet of conventional wisdom
stanley cups uk , however, has absolutely no objective evidence to support it. In fact, in a 1987 study it was shown that yawning neither increased nor decreased when oxygen and carbon dioxide levels were increased. This has caused some scientists to conclude that yawning has nothing to do with oxygenating the blood. Yawning stimulates and aids in arousal It has been noted that, across species, yawning appears to happen in anticipation of important events and during behavioral transitions. That yawning facilitates a heightened state of alertnes
