Here are some very cool links about yawning in general and why it is contagious:\n\nhttp://www.howstuffworks.com/question572.htm\n\nhttp://staff.washington.edu/~chudler/yawning.html\n\nhttp://www.world-science.net/exclusives/050309_yawnfrm.htm\n\nBy the way, excellent question.  Hope this helps.\n\nGod Bless!  :)

The recurring eye twitch I was going to say could easily be a vitamin deficiency. But then I opened the question and read the details. That would be a little disconcerting. You know, it never hurts to go see your friendly neighborhood doctor and just have everything checked out occasionally. Oh I know the turn your head and cough bit is a tad uncomfortable too, but hey.........at least you don't have stirrups. Ok the point being....go see the doctor no matter what is going on in your head. And don't procrastinate because you are afraid of bad news. He'll probably tell you to start eating right and get more exercise. That feeds your brain more vitamin B and that just might take care of everything! So listen to those people that wrote above me. Make an appt. soon........but let us know how it goes.

There are two possible reasons for tears to be released when you yawn. \nThe tears are secreted by the "lacrimal glands" located just inside the eye \nlids next to the nose. These glands secrete the fluid into the "lacrimal bag" \nwhere it is then released through the "lacrimal ducts" into the lining of the \neye lids to keep the eye moist.\n\nWhen you yawn it is possible that there is pressure put on the "lacrimal \nbag" and some fluid is forced out. \n\nThe secretion of the "lacrimal glands" is under control of the autonomic \nnervous system. This nervous system controls all the involuntary functions \nas contrasted to the somatic nervous system that controls all purposeful \nactions. When you reach out to catch a ball it is the somatic system that \nactivates the muscles to acheive that action. The autonomic system \ncontrols such things as the heart beat, sweating and the function of the \nintestines.\n\nWhen the autonomic portion of the nerves are activated the "lacrimal \ngland" secretes the tears which appear at the eye. These nerves also \ncause the pupil of the eye to constrict and get small as well as to cause\nthe glands in the nose to secrete. So, when you are crying you get tears,\na watery nose and your pupils should constrict. Perhaps the act of \nyawning causes activation of these nerves. Next time you yawn look in \nthe mirror and see it your pupils get small. But don't get too close to the \nmirror because when you look at things close to you the pupils get smaller \nanyway.

I have the same problem - No one has mentioned "environment" (that I saw?) - It's now Spring - What kind of climate do you live in? I'm in CO - and the Humidity today was 8% (Yes, EIGHT percent) - but "cold" so the heater was blasting all night ... so dry air effects me as well as lack of moisture that comes with higher humidity...\n\nOption #2) - Do you take Tylenol PM (or any antihistamines?) - For whatever reasons - these too dry out my eyes (well, B/C they're a type of antihistamine)\n\nOption #3) - People have already mentioned allergies... and alcohol - May wanna check with an allergist about down pillows, or Spring hay fever - or even "mold" if you are in a northern climate, and the windows are sealed - I found my "allergies" were worse in the winter than summer, and never understood this since all plants/trees/weeds and such are "dead" (dormant) - well, turns out Mold in the air ducts was the cause... \n\nIf you go to a Doc, and tell him about using "Clear Eyes" or "Visine" - those too have a "rebound effect" and he'll (she'll) encourage you to go to "natural tears" for the others' can CAUSE red eyes after long term use... But I too still use them, cuz "natural tears" don't remove the red - and don't wanna look hung over at work - When I'm NOT! LOL \n\nCheers and good luck!

A yawn is in response to too much CO2 in the blood stream.  When you yawn there is a negative feed back loop in operation which tells the diaphram to contract (take a breath) because there is too much CO2......the yawn actually increases CO2.\nThe sneeze is due to irritation in the beginning of the respiratory tract, it expells such things as dust, bacteria and other irritants from your nose and sinuses.\nA hiccup is a sligh malfunction or mistiming if you will of the glottis which is a membrane that closes in your throat to prevent food from going into your lungs when you swallow.  Whenyou ge tthe hiccups it starts to close while you are taking a breath or expelling a breath.  It just takes a bit of time for your body to reset when it closes

oh my god theres an invasion of yawning questions

From Wikipedia:\n\n"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 not correct. One study has documented that this effect does not exist."\n\nGoes on to newer, updated theories.\n\nAlso:\n\n"The reasons for this are unclear; however, recent research suggests that yawning might be a herd instinct. Other theories suggest that the yawn serves to synchronize mood behavior among gregarious animals, similar to the howling of the wolf pack during a full moon."\n\nGoes on to give other reasons for contagion. <Yawn!> Enough!

Personally, I think it's a sub-conscience action since you don't have to be aware of someone else yawning. Think of it this way, you weren't hungry until you saw, smelled, or someone mentioned food. So as you idle your body equates lack of action as rest. As we all know, rest is equated to sleep, so your idle body wasn't tired until someone yawned. \n\nI know it sounds odd but, have you ever yawned while your cardio system was working harder than compared to sitting idle?

Ha! This is a great question! I have thought about this one myself! while in College, I took a speech class, and I soon found out the answer to this! When one talks for a long period of time while being nervous, the mouth will dry up like a piece of cotton because all of the needed fluids go to other places (the hands, feet...sweating...gross isn't it?). My Speech Teacher told the entire class to drink water instead of any other fluid, because it was/is the only fluid to not make the mouth even more dry! So, to test this(I thought that she was crapping me!) I decided to drink a soda while giving a speech....I could barely talk due to the dryness! Water is the only fluid that keeps the mouth from being so dry in such a situation!

i think i might know what you are talking about, i think the reason y u have weird noises is because u might just be burping. when u breathe in deeply u swalow some air that needs to be released. when u yawn do u have those noises too?

I would say either you are really really tired, or you have an allergy to something in your environment. Mine burn a lot when I am extremely tired.

Professor Andrews told Scientific American yawns may be contagious because we human animals are trying to communicate changing environmental conditions to others, possibly as a way to synchronize behavior. Obviously, this would be one of those caveman-type mechanisms that is no longer needed that our bodies remember and still do.\n\nWhen we yawn, we draw in more oxygen and remove a build-up of carbon dioxide. Larger groups produce more carbon dioxide. So one theory holds that we yawn when we're in large groups of people to purge the carbon dioxide--and in so doing, we set off a chain reaction. But Robert Provine, a psychologist at the University of Maryland, Baltimore County, tested the theory and says it's bunk. Giving people additional oxygen didn't decrease yawning and decreasing the amount of carbon dioxide in a subject's environment also didn't prevent yawning, notes the How Stuff Works Web site.\n\nWhatever the reason for yawns being contagious, How Stuff Works reports that 55 percent of people will yawn within five minutes of seeing someone else yawn. In addition, blind people will yawn after hearing others yawning. And we're sure that reading and writing about yawns is enough to induce one!

Oh ardent one, I hope I understand your question.  I know I'm ahead of the game because it didn't cross my mind, you'd want a boyfriend.  I help people deal with various issues in life and I have noticed that when they realize something or they get a release of sorts, they often yawn.  I find it fascinating.\n\nDo I notice a particular emotion just prior to yawning?  Yes, on the rare occasion that I feel intimidated, I notice I yawn.
