why do we yawn?
As for why we yawn, I couldn't explain it well, but as for how not to; that's easy enough.
The trick is to notice the yawn when it is coming, then just make a conscious effort to hold your mouth shut.

It used to be thought that it was caused by excess CO2 and was a response designed to draw more air into the lungs to compensate.
Recently another theory has surfaced - it regulates the body temperature.
In other species the Yawn has a specific meaning - eg Adelie Penguins yawn as part of courtship.
And a final useless fact which made me smile - 6% of patients with depression treated by the drug Clomipramine have an interesting side-effect - Yawning causes orgasm.

MythBusters say... the narrator says that there's no real clear evidence of why we yawn...

nice!! i yawn a lot at work, even in the presence of my boss!
you simply yawn because ... you know when you get bored or when you free sleepy you just yarn. do you know to know??/ when you yawn more than 100 muscles movements are involved
The wikipedia says
at: http://en.wikipedia.org/wiki/Yawn
To stop yawning, whenever it feels like yawning just concentrate your mind elsewhere!
I know this helps!!

A more recent hypothesis is that yawning is used for regulation of body temperature. Another hypothesis is that yawns are caused by the same chemicals (neurotransmitters) in the brain that affect emotions, mood, appetite and other phenomena. These chemicals include serotonin, dopamine, glutamic acid and nitric oxide. As more of these compounds are activated in the brain, the frequency of yawning increases. Conversely, a greater presence in the brain of opiate neurotransmitters such as endorphins reduces the frequency of yawning. Patients taking the serotonin reuptake inhibitor Paxil (Paroxetine HCl) have been observed yawning abnormally often. Another theory is that yawning is similar to stretching. Yawning, like stretching, increases blood pressure and heart rate while also flexing many muscles and joints. It is also theorized that yawning helps redistribute an oil-like substance which coats the lungs and aids breathing. Some have observed that if you try to stifle or prevent a yawn by clenching your jaws shut, the yawn is unsatisfying. As such, the stretching of jaw and face muscles seems to be necessary for a good yawn. |

When you feel a yawn coming on just close your mouth. Its as simple as that. It works for me, maybe others can't focus as hard on it, but I can. I do it when I am in class or somewhere else where it would be improper/rude to yawn.
i yawn everytime... especially in college lectures
and i read somewhere, v yawn whenvr our body needs more of oxygen
and i read somewhere, v yawn whenvr our body needs more of oxygen
Some say that it is for oxygen... But I've also heard a quite interesting theory!
In the primal world, the first human used to sleep at very irregular times. So, when they lived together, one of them yawning would mean that the time to go to bed had came and that the surrounds were safe. This would explain why someone yawning near you leads you most of the time to yawning too!

Yawning, it has scientific reason. We yawn just not we are felling lazy its because our body is lacking oxygen and while yawning we take lot of air to fulfill the need of oxygen to our body. Before yawning we feel lazy thats because CO2 content our body is more than normal. And due to lack of oxygen different parts of lour body doesn't function well and moreover respiration process is laking, i.e. burning of food in our body is in less amount and the required energy in our body is lacking, that is why we feel lazy.
And there no a way to stop it. You can do something to prevent it from coming. When you feel like yawning then just sit and rub your hands on your things very fast or jump a few times, i think you will not feel like yawning .
Just give it a try, i am sure it works.

this is really freaky lol, after reading this topic ive started yawning lots, i just cant stop.
i assume its to get oxygen to the lungs and to exercise muscles to avoid cramp, cos when you think about it, when you yawn, you usually strech or shift position.
intererting thought about ye old human though.

I always though yawning was the expansion of the lungs bringing more oxygen in your body, but I had not thought about it when you are sleepy you tend to yawn more. I don't really care about stopping yawns because as soon as I start to yawn I tend to stretch out (which feels good), but as far as stopping it I don't really care
I don't know. All I know is that whenever I think about yawning, see/hear the word a lot or whatever, liek in this thread, it makes me yawn. It's a horrible thing :X

I don't think it's possible to stop yawning. Has anyone done any research on it?
We yawn when we are bored and tired. Maby it is to get more oxygen or maby it is to keep the face from freezing up and sticking that way like your mom used to tell you.
its cuz your tired silly
Wikipedia was relating a yawn to a stretch; that might be the real cause; perhaps yawning is just a way to stretch your facial muscles and joints?
Reading this is making me yawn... as for how to stop it. I suppose making a conscience effort to stop it when you feel it coming on might do the trick, but I've always found doing so just made we want to yawn even more, As for the cause, theories are nice, but no one really knows.
1. The average duration of a yawn is about 6 seconds.
2. In humans, the earliest occurrence of a yawn happens at about 11 weeks after conception - that's BEFORE the baby is born!
3. Yawns become contagious to people between the first and second years of life.
4. A part of the brain that plays an important role in yawning is the hypothalamus. Research has shown that some neurotransmitters (for example, dopamine, excitatory amino acids, nitric oxide) and neuropeptides increase yawning if injected into the hypothalamus of animals.

it was because your were in a boring meeting or class that caused yawning.
The way to avoid it... don't take boring classes or jobs!
simple enough

I've heard several times that it's a social behavior since we were cavemen sitting around campfires.
Get plenty of fluids, plenty of rest, that sort of thing. Exercise. You'll probably yawn less and feel better to boot.

we yawn to equalize the pressure in our ears with the outside air.
so..
yawns are contagious because if one person equalizes the pressure in his ears, this small change slightly throws off the equilibrium between the outside air with another person's ears, so he yawns. then it happens again, and so on and so forth.
... not really though
but it's a good theory

To stop a yawn
Method 1: When you feel an approaching yawn, close you r mouth and take a deep breath through your nose. This will satisfy the bodies need for oxygen.
Method 2: Jump up and down and make chicken sounds. This might not stop the yawn but will stop people noticing it by distracting them.

that classes are boring because the pressure is different?
The reason why you yawn more often when you are tired or sleepy, is that your body is slowly trying to convince you to go to sleep. Doing so, it lowers the activity of the brain and muscle movement. To be able to breathe we use the muscles between our ribbs. When your body slows down musclemovement, your muscles between your ribbs experience that same effect. And then everything else that has been said before kicks is. You body gets low on oxygen en high on carbondioxide so your hypothalamus sends a signal to your breathing muscles. This signal causes you to yawn.
The same thing happens when you are bored. When you are bored, your mind wanders off: daydreams. For your body, it seems almost like going to sleep. So it's basicly the same effect as above

I always thought that one yawns to get more blood to your brain
Makes sense, no?
cos I've tried yawning without breathing in, and I had the same effect as breathing in, but I did the same without the "back of jaw pumpy feel" and breathing in a lot, and I STILL had to yawn.
anecdotal evidence, case closed!

I usually yawn to "crack" my ears. I was always told yawning was meant to accomadate air pressure changes, I don't really believe it though.
I notice that a few people here have spotted the fact that yawning is contagious.
The very act of yawning a few times or one good satisfying yawn can make others around your yawn too whih can lead to a chain reaction among a gathering of people - try it, it works.

Please use quote tags when posting other peoples work. Tags added by Moderating Team Hypothesised causes of yawning 1. An indication of tiredness, stress, over-work, or boredom. 2. An action indicating psychological decompression after a state of high alert. 3. A means of expressing powerful emotions like anger, apathy, remorse or tedium. A previous long-standing hypothesis is that yawning is caused by an excess of carbon dioxide and lack of oxygen in the blood. The brain stem detects this and triggers the yawn reflex. The mouth stretches wide and the lungs inhale deeply, bringing oxygen into the lungs and hence to the bloodstream. It is almost certain, however, that this hypothesis is incorrect. One study has documented that this effect does not exist. A more recent hypothesis is that yawning is used for regulation of body temperature. Another hypothesis is that yawns are caused by the same chemicals (neurotransmitters) in the brain that affect emotions, mood, appetite and other phenomena. These chemicals include serotonin, dopamine, glutamic acid and nitric oxide. As more of these compounds are activated in the brain, the frequency of yawning increases. Conversely, a greater presence in the brain of opiate neurotransmitters such as endorphins reduces the frequency of yawning. Patients taking the serotonin reuptake inhibitor Paxil (Paroxetine HCl) have been observed yawning abnormally often. Another theory is that yawning is similar to stretching. Stretching, like yawning, increases blood pressure and heart rate while also flexing many muscles and joints. It is also theorized that yawning helps redistribute an oil-like substance which coats the lungs and aids breathing. Some have observed that if one tries to stifle or prevent a yawn by clenching one's jaws shut, the yawn is unsatisfying. As such, the stretching of jaw and face muscles seems to be necessary for a satisfactory yawn. Yet another theory is that yawning occurs to stabilize pressure on either side of the ear drums. The deep intake of air can sometimes cause a popping sound that only the yawner can hear; this is the pressure on the inner ear stabilizing. This commonly occurs in lower-pressure environments, such as inside an airplane, which cause the eardrums to be bent instead of flat. Some movements in psychotherapy such as Re-evaluation Counseling or co-counselling believe that yawning, along with laughter and crying, are means of "discharging" painful emotion, and therefore can be encouraged in order to promote physical and emotional healing. |
lol, i yawned
More bizarrely, why is yawning contagious? It's fun to watch, if you're in a room with 6+ people, and you yawn. Look around for about a minute, you'll find someone else yawning, and then someone after that. I do that a lot during lectures.
"Just because you read the word 'yawning' in the previous sentence - and the additional two 'yawns' in this sentence - a good number of you will probably yawn within the next few minutes. Even as I'm writing this, I've yawned twice. If you're reading this in a public place, and you've just yawned, chances are that a good proportion of everyone who saw you yawn is now yawning too, and a good proportion of the people watching the people that watched you yawn are now yawning as well, and on and on, in an ever-widening, yawning circle."
eh, funny quote from "The Tipping Point" by Malcolm Gladwell.

It is the lack of oxygen which causes it, I suppose. If you want to reduce yawning, exercise your body well. A good exercise; a good sleep would both reduce yawning.
It is because of a lack of oxygen to your brain, that is also why you feel the tiredness. Yawning is just gasping for as much air as you can get. It is contagious because most likely the people in the same room as you will also have a lack of oxygen and your brain copies what they are doing so it can get more oxygen.
I hope I helped in some way.
I hope I helped in some way.
Its just because your brain need more air... If you start yawning just take some big breaths and it will stop. Also dont be in small rooms with many peoples... Just some tips 
I really don't know.. I just wanted to add that animals do it too...
it's so that other people (like me) can have fun tryin to aim throwin stuff in your mouth!
