Found: New Reason For Yawning

Dear Reader,

Next time you see someone yawn (or you do this yourself as you read about yawning) don't take it as a sign of boredom or fatigue, science is learning that the yawn does far more than we ever thought. Yawns do more than serve a respiratory purpose by delivering more oxygen to the brain; research has found the frequency of yawning is not related to brain or blood levels of oxygen or carbon dioxide. It wasn't until 2011 that researchers identified yawning as a potential brain cooling mechanism that brings a large amount of the surrounding air into the body.

Until recently yawning had the distinction of being the most common but least understood behavior out there. It does seem to be more intense when you feel very sleepy. The most recent work in the area, conducted by researchers at the University of Vienna, confirms that yawning is indeed a sign that your brain is running too hot. Yawns appear to be a natural brain cooling mechanism that the body uses as needed. Yawns provide a deep inhale of the air around you and offer a counter current heat exchange to boot.

The average yawn lasts from 4 to 7 seconds, an involuntary action that has us opening wide and breathing deeply. Experts know the yawn is involuntary because an 11-week-old fetus can do it. You don't choose to yawn; you simply do it, yawning unconsciously and spontaneously. You can't yawn on command, and there are times where you can't keep a yawn quiet. What's more, a yawn can up your heart rate by as much as 30%. There are two recognized forms of the yawn, spontaneous and contagious, and both have similar action patterns.

Found: New Reason For Yawning Continued...


Spontaneous yawns appear to be brought on by physiological mechanisms involved in achieving optimal homeostasis. Contagious yawns are triggered just by sensing or thinking about yawning in others. Interestingly these types of yawns are only seen in people, apes and dogs, though all vertebrates (even fish) yawn.

For the current work, the team performed tests on subjects in warm, dry Arizona and cold Austria and kept track of yawning activity of those walking outside during summer and winter months. Yawning appears to happen within what's known as a "thermal window", an optimal temperature span. Until now, no one had looked at the lower end of that thermal window might be. The researchers noticed that the only reliable predictor of yawning was actually temperature - the participants in Vienna yawned more in the summer than in the winter; in Arizona the subjects yawned more in winter than in summer. Turns out it wasn't the season or daylight hours experienced by subjects that impacted yawning, but rather an optimal temperature of 20 degrees Celsius, decreasing as temps rose higher, around 37 degrees Celsius in Arizona's summer; and dropped to freezing as in Vienna's winter.

If a large intake of air will bring your body temp down, you're far more likely to be yawning. This research builds on early studies (in both humans and rats) that yawns are preceded by intermittent rises in the temperature of the brain, and that the temperature goes down right after the yawn. A cooler brain is able to think more clearly, so the yawning mechanism may well have developed over time as a way to keep people alert and aroused.

To your good health,

P.S: There's a knock at the door. You peak through the curtains... a neighbor you weren't expecting.

You cast an eye over the room - it's a total mess! Shall you pretend to be out...?

We've all been there - caught out and embarrassed by the state of our homes.

Wouldn't it be great to always have a home that's free of clutter, one you're proud of rather than embarrassed by?

Now you can.
