5 Interesting Things We Believe about Yawning [Backed by Science! 3-5 Min Read Time]

You may have felt mightily offended when someone yawned in the middle of your brilliant discourse, but it may not even be because of boredom. It may be just a matter of an overly warm room. Here are five interesting things we believe about yawning based on research.

1. Yawning is cool

The next time someone yawns while you’re talking, it may be because you are making them think, so take it as a compliment!
One study shows that yawning may actually help in regulating a “warm” brain, cooling it down to help someone concentrate better and think more clearly because of physiological changes that occur unique to yawning. Researchers estimate that higher ambient temperatures (>20° C) tend to increase the number of times a person yawns, regardless of any other stimuli. Yawning also occurs more frequently when the brain is “warm” due to stress, cortical arousal (i.e. thinking), and sleep deprivation. The last factor is common, which is why yawning is often associated with sleepiness.
Instead of yawning, you can cool down your brain by breathing through your nose or putting an ice pack on your forehead, but it is much less satisfying.

2. Yawning is a survival mechanism

You may have heard that yawning is contagious, but do you know why? Researchers at the State University of New York at Albany set out to find out, and believe they know: survival! The study confirms that yawning cools the brain and increases alertness, but the researchers believe the reason it spreads from person to person, especially among those that share an emotional or genetic bond, is to keep the group alert as a whole to any danger that may exist. It is particularly true While there is not much chance of anything physically dangerous happening in a classroom or office, this survival mechanism persists. At any rate, it makes you more alert, which is always a good thing.
Interesting fact: Psychopaths are immune to contagious yawning because they lack empathy.

3. Yawning may signal development problem

Doctors often witness unborn babies yawning, but it is probably not because they are bored in the womb. Some researchers think that frequent yawning beyond the 36th week may indicate a problem in the brain development of the baby in utero. This is not actually a fact, but it may be an early indication of problems with fetal development, at which point the doctors may choose to carry out more tests.

4. Yawning may indicate a health problem

While yawning does have a useful function, yawning too much may mean you have a health problem. It may be due to a stimulation of the vagus nerve, which is a symptom of a tear in the aorta (aortic dissection) or a heart attack (myocardial infarction). It may also indicate a problem with the brain, such as multiple sclerosis, epilepsy, tumor, or stroke. If you think you are yawning excessively, consult with a physician.

5. Yawning longer means a bigger brain

Yawning is not exclusive to humans. Primates and other mammals also yawn, but there are some differences. A study of 29 YouTube videos of animals yawning suggests that the longer the yawn, the larger the brain. To put it in context, mice yawn for an average of 1.5 seconds, while humans yawn for an average of 6 seconds.
Now, don’t start practicing longer yawns! It doesn’t work that way.

Conclusion

Despite the number of studies focusing on the nature of yawning, we don’t actually know much know about it. Everything stated above are merely scientific observations and best-guesses, not facts. However, there is enough evidence to support them as a working hypothesis for future research. In addition, you have to admit they’re mighty interesting!

Maan... I gotta visit my GP. I thought I was just bored at life. I might just have a problem.

·

Have your GP check it out. Better to have checked and find nothing than to have not check and there is something. Good luck!

Those were really very interesting facts, who would know that yawning longer means you have a bigger brain

·

I know right! I was surprised when I was reading the source materials myself.

·
·

You think if helping myself yawning makes me a bit wiser or help me to have more bigger brain?

While reading your article @frost04 I yawned about 5 times. And the last part made me smile as I actually tried to yawn longer. Hahaha!

I always enjoy your writing. It is very easy, smooth flowing. And very interesting. Thanks for sharing.

·

I write for these kind of complitments. Thank you :)

Do you intend for this to be funny? I can't count how many laughs I made! Haha!

Very interesting, nice article @frost04!

I do my best to make it light. Glad you liked it.

While yawning is a normal bodily activity, too much yawning might mean that you are suffering from an underlying medical condition. Excessive yawning is one of the ‘rare’ symptoms of heart conditions, as oscitation is a result of vagus nerve reaction. Too much Yawning might signify brain illnesses as well.

Do you practice medicine. You sound like a doctor. :)

i am not a doctor :) but i used to read lots of articals about how human system works. so i knew few medical terms.

the fact - interesting facts from a research, very reasonable, according to me? evaporate is a fatigue in humans caused due to lack of sleep?
