Yawning is usually associated with being tired, stressed, overworked, or bored. It has an infectious quality. Seeing other people yawn or even thinking of it can trigger the response. I’ve yawned at least ten times already since I started writing this. Hold on… make that eleven.
Why do we yawn? One theory is that when we are bored or tired, we don’t breathe deeply enough. As a result, our bodies take in less oxygen. So, yawning helps us take in more oxygen and hastens the removal of carbon dioxide, which then helps keep us awake.
But some specialists believe yawning isn’t just about keeping us awake. Dr. Andrew Newberg is an Assistant Professor in the Department of Radiology at the Hospital of the University of Pennsylvania. According to Dr. Newberg, yawning is one of the best-kept secrets in neuroscience:
But yawning doesn’t just relax you—it quickly brings you into a heightened state of cognitive awareness. Students yawn in class, not because the teacher is boring (although that will make you yawn as well, as you try to stay focused on the monotonous speech), but because it rids the brain of sleepiness, thus helping you stay focused on important concepts and ideas. It regulates consciousness and our sense of self, and helps us become more introspective and self-aware. Of course, if you happen to find yourself trapped in a room with a dull, boring, monotonous teacher, yawning will help keep you awake.
Dr. Newberg explains that yawning triggers various neurochemicals to be released, including dopamine, which activates oxytocin production in brain areas essential for memory recall. In addition, these neurotransmitters regulate pleasure, sensuality, and relationship bonding between individuals. He says, “If you want to enhance your intimacy and stay together, then yawn together.”
Try yawning when you feel anger, stress, or before tackling an important task. Yawning during prayer or meditation can intensify the experience. While it takes a bit of practice, for best results, Dr. Newberg suggests consciously yawning as many times a day as possible.
Sure, you might look bored and disinterested, but at least you’ll feel great!

This is a yawn plus a good stretch, which is actually called "pandiculation"
