Hereâs What Happens In Your Body When You Yawn (At Least In Theory) Much of the research done on the subject actually focuses on contagious yawning -- a phenomenon in which we yawn in response to watching someone else do it (and can even yawn from just hearing mention of the action). What's more, we are even more likely to yawn when we watch a close friend or family member do so. Most of the research on contagious yawning (though a recent paper questioned this connection) has focused on the role of a low-level, primal type of empathy.

We now know, however, that the lungs do not necessarily sense oxygen levels. Moreover, fetuses yawn in utero even though their lungs aren¿t yet ventilated.

Is yawning contagious? If so, why? What's the evidence? The physiological theory: Our bodies induce yawning to draw in more oxygen or remove a buildup of carbon dioxide. This theory helps explain why we yawn in groups. Larger groups produce more carbon dioxide, which means our bodies would act to draw in more oxygen and get rid of the excess carbon dioxide.
