Yawns

Wow, I don't know what to write.


Did you think I was going to write about yawns? Yes, thou art right.

I DO NOT INTEND TO BORE YOU. I'm just going to share with you all the wonder of yawns :P

Next time you're in a meeting, try this little experiment: Take a big yawn, cover your mouth out of courtesy and watch to see how many people follow suit. There's a good chance you'll set off a chain reaction of deep breaths and wide-open mouths.
Apparently, no one has come up with a perfect explanation to the mystery behind yawns.. yet!

(The science bit) 

So what's behind this mysterious epidemic of yawning? First, let's look at what this bodily motion is: Yawning is an involuntary action that causes us to open our mouths wide and breathe in deeply. We know it's involuntary because we do it even before we're born: According to Robert Provine, a developmental neuroscientist at the University of Maryland, Baltimore County, research has shown that 11-week-old fetuses yawn. And while yawning is commonly associated with relaxation and drowsiness, your heart rate can rise as much as 30 percent during a yawn, and yawning is a sign of arousal, including sexual arousal.

Many parts of the body are in action when you yawn. First, your mouth opens, and your jaw drops, allowing as much air as possible to be taken in. When you inhale, the air taken in is filling your lungs. Your abdominal muscles flex, and your diaphragm is pushed down. The air you breathe in expands the lungs to capacity and then some of the air is blown back out. YAWNING IS EXERCISE :O

(The fun bit) 


Did you know, even just thinking about yawning or reading about yawning can make humans yawn.
So, basically, if you are normal, you must have yawned at least once while reading this article :)
Yawning is considered rude in most parts of the world. So, make sure you cover your mouth while doing so. Plus, no one is really interested to see in there.  

Facts : 

1. We yawn before we’re even born; 11-week-old foetuses have been known to yawn in the womb.
2. Yawns start becoming “contagious” when we’re between the first and second years of our lives.
3. If one person in a group yawns, more than half of the people in the group will yawn in five minutes (the rest will be tempted to yawn).
4. Animals have been known to yawn when they see other animals yawning.
5. Men yawn longer than women.
6. Yawns last, on average, six seconds.

On a more serious note, if you that you perform frequent yawning, you may want to see a doctor, for you may have an underlying medical condition, one that could be serious.


Chao, babloos.
