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.

When your friend stifles a yawn as you chat, don’t be offended. Instead, take it as a compliment. For, far from being a sign of boredom, yawning may signal empathy.

- Well, you’re not really “joining in,” because you aren’t copying the yawn on any conscious level. It happens because you just can’t help it. If you become self-conscious about a yawn, it stops. Studies have shown that seeing pictures or videos of yawning faces can provoke contagious yawning. What we might think of as the main component of a “yawn face”—a wide-open mouth—doesn’t even need to appear in the image for the trigger to work, “yawning eyes” can be enough to get us arching and gaping.

Asthma, yawning and sighing respirations However, it is clear that yawning and deep breathing can be associated with stress and anxiety, and such can be interpreted by the patient as dyspnea. In an asthmatic who interprets the need for yawning or sighing respirations with deep breaths as dyspnea, the dyspnea is oftentimes attributed to asthma. I can only hypothesize in your patients the yawn and the deep breaths (probably sighing respirations) are related to stress, and that they are interpreting the sensation of dyspnea that goes along with these disorders of breathing as being due to their asthma.

Is yawning contagious? If so, why? What's the evidence? The evolution theory: Some think that yawning began with our ancestors, who used yawning to show their teeth and intimidate others. An offshoot of this theory is the idea that yawning developed from early man as a signal for us to change activities [source: University of Washington]. The boredom theory: Although we do tend to yawn when bored or tired, this theory doesn't explain why Olympic athletes yawn right before they compete in their event or why dogs tend to yawn just before they attack.

- Yawning excessively is when the act of yawning occurs repeatedly or in close succession. When you yawn, your mouth opens and you take in a deep, long breath. Sometimes this is accompanied by a sigh. Yawning is a normal response by the body to drowsiness or fatigue. Yawning may also be triggered by observing someone else yawning. Yawning excessively may mean taking in this deep breath more often, generally more than a few times per minute. This can occur when you are tired, weary or drowsy.

Why do we yawn? In humans, yawning can start as early as 20 weeks after conception. A yawn is a coordinated movement of the thoracic muscles in the chest, diaphragm, larynx in the throat, and palate in the mouth. By yawning, we help distribute surfactant (wetting agent) to coat the alveoli (tiny air sacs) in the lungs. Generally speaking, we cannot yawn on command.
