In Praise Of The Yawn: Some Fascinating Facts

Let's say you're sitting in a meeting at work, and you feel a yawn coming on. (We've all been there, haven't we?) If you're like most people, you probably try to stifle it. And if that doesn't work, you try to discreetly hide the yawn behind your hand. After all, yawning is rude and a sign of boredom or fatigue - neither of which you want to display when your boss is outlining a new project. Right?

Wrong, actually. (About what yawning means, not about your intentions toward your boss)! According to mind training expert Patt Lind-Kyle, your yawn isn't a sign that your boss is putting you to sleep. Rather, it's a signal that your body is revving up your brain so that you can more efficiently process what she is saying.

"Many people believe that yawning in the presence of others is disrespectful," observes Lind-Kyle, author of "Heal Your Mind, Rewire Your Brain: Applying the Exciting New Science of Brain Synchrony for Creativity, Peace and Presence" (Energy Psychology Press, 2009, $26.95) and mind training guide whose voice appears on the book's companion CDs. "The truth is, yawning has unfairly earned a bad rap. It's actually the body's way of rejuvenating the brain so that it can function more effectively."

In scientific terms, a yawn is characterized by an inhalation of air that stretches the eardrums, followed by an exhalation. Yawns are occasionally accompanied by a stretch - for the curious, that's called a "pandiculation." Sometimes yawns are reflexive, and sometimes they are intentionally self-induced. And, Lind-Kyle points out, they always entail much more than just a wide-open mouth.

Lind-Kyle has devoted years to the study of the human brain-mind and its complex relationship with the body and with human behavior. While her primary focus lies in rewiring the brain's neuronal pathways to correct mental imbalances and dysfunctional behaviors, she has also become fascinated by many of the human body's seeming quirks that actually serve vital purposes - yawns included!

Chances are, you've never given your own yawns a second thought. However, they may deserve one! Read on to learn how yawning impacts the brain, and why you should consider doing so more often. (And yes - it is possible to yawn on command).

Yawning increases mental efficiency. It's no secret that it takes a lot of energy to stay focused when you're engaged in concentrated activity. The mind has a tendency to wander and to slip from the task at hand, and this is when you might find yourself yawning. What you're actually doing, says Lind-Kyle, is stimulating a neural area of the brain that plays a major role in being more conscious and self-reflective, and that also aids in relaxation, alertness, and maintaining a good memory. Any time you breathe deeply, your brain waves slow down and your muscles get the message to relax.

"The next time you're stressed out and trying to maintain your focus, consciously take a moment to yawn every 20 minutes or so, and then sit back and relax," suggests Lind-Kyle. "You'll notice a difference."

 • Yawning helps the brain maintain balance. Research has found that yawning helps cool down the overactive brain as it attempts to regulate its temperature and metabolism. In fact, yawning increases when people are engaged in difficult mental tasks - something you've no doubt noticed in your own life!

 • Yawning staves off sleep! This revelation might be the most surprising of all, since most of us operate under the impression that yawning makes us sleepier. Once again, science debunks conventional wisdom. Yawning helps contract the facial muscles, which forces blood through cerebral blood vessels to the brain - and this, scientists say, may function to increase alertness. Thus, yawning may reduce sleepiness as it reflects a mechanism that maintains attention.

 • Yawning helps you "reset" yourself. That's right - it's almost like pushing the "reset" button on an electronic device. When you yawn, you help regulate your body's circadian rhythms, or the roughly 24-hour cycle of human behavior and biological activity. This is true for babies, patients coming out of comas, and partygoers who are returning home from a night out. Yawning also increases when people are in the midst of a change from inactivity to activity, and vice versa.

"Yawning really does help you reset your internal clock," says Lind-Kyle. "In scientific terms, it arouses your neuromuscular wiring and creates a harmonious progression in the brain stem. When you're traveling by plane and changing time zones, remember to yawn to help reset your circadian rhythms. Yawning will help to reduce the effects of jet lag."

 • Yawning can lift your mood - and maybe even save your marriage! When you yawn, your dopamine levels rise. This activates oxytocin, or pleasure and relationship-bonding chemicals. The more these chemicals are activated, the more frequently you yawn. Yawning is also contagious, because it triggers the mirror neurons that literally prompt you to reflect another person's behavior or emotional state. People who are on antidepressants may experience yawning more often, especially in the first three months of taking the SSRIs.

In other words, yawn away - and don't feel self-conscious about it.

The Art of the Yawn: Six Snooze-worthy Suggestions for Making Yourself Yawn

 • The Sloth: Consciously slow down your breathing. The change in oxygen levels will make your body instinctively want to gulp in more, in the form of a yawn!

 • The Slow Sniff: Flare your nostrils while breathing in. After a few repetitions, you'll probably feel the irresistible urge to open wide!

 • The Monkey-See: Close your eyes and try to imagine someone yawning, or repeat the word "yawn" to yourself over and over again. Sometimes the power of suggestion is all you need. After all, everyone knows that yawns are contagious. (There's a good chance you're yawning as you read this!)

 • The turtle: This series of actions will probably make you yawn - Shrug your shoulders, bringing them as close to your ears as possible; keeping your shoulders high, thrust your head forward; simultaneously lower your shoulders and bring your head back to its normal position; repeat! This pattern of motions will cause you to breathe irregularly, which will in turn cause you to yawn.

 • The Thespian: Get in touch with your inner actor or actress and try for an Oscar-winning depiction of a yawn. It just might turn real in the middle!

 • The Pandiculation: A pandiculation is the act of yawning and stretching simultaneously. If you want to yawn, try stretching your arms above your head, flexing your wrists. Then bring one or both fists down to your shoulders. Maybe this "morning stretch" will start a chain reaction.
