Yawning

I suggest you go see a doctor as soon as possible. You might get a concussion.

Technically, no it doesn't. it's one of the bodies natural reactions to a buildup of CO2 in the body

The reason for yawning is to send oxygen to the brain in order to replenish it, it's basically your brain falling asleep on you.

Yawning is actually putting out (?) the stress in your body, so it is a good thang...

By doing a fair test. You have to ensure that there are no external triggers that could affect your results eg testing yawning after a particularly boring seminar. A good test would be at the local mall. Have a group set up to smile at strangers and a group set up (at the other end) to yawn at strangers. Monitor their responses. If you do it on the same day you are taking a similarly representative sample ie homemakers and shopping moms. In fact you could target women at a mall and run an identical test (yawners at one end, smilers at the other) at a ball game to see if men were equally susceptible.

Of course there are problems with this. Who is smiling? Who is yawning? Do people smile back at a blue eyed, busty tester more than a black, male assessor? Are yawns contagious despite ethnicitiy or do black people respond more to black yawners and vice versa? Testing human behaviour is not an exact science!

It is because of lack of oxygen, tiredness, or boredom. Another interesting thing is some researchers also believe that groups of the stone age men yawned to intimidate others by showing their teeth, or to show the group a sign it's time to retire or sleep. Also the people who yawn were considered less energetic and hence were protected and sheltered by the others, not allowing them to get in to any danger.

The sublingual caruncle is found under your tongue (either side of the frenulum - the small folds going from your tongue and the cavity floor).

This is where two salivary glands, the sublingual and submandibular glands, empty into the oral cavity. That is why saliva will sometimes spray out when you lift your tongue while yawning.

No it is provin to brake the jaw bone, this can lead to internal bleeding which will kill u and f**k up your life

It is not uncommon. Instead of a long answer I'll just refer you to:

Yawn doesn't have a TM number because it isn't a TM.

Yawning, particularly if you have some congestion due to cold or allergies, helps even out the pressure on both sides of the eardrum. This allows it to operate properly to transmit the sound waves correctly.

Most people yawn about 5 to 10 times per day on average. Yawning is a common involuntary reflex that helps regulate oxygen and carbon dioxide levels in the blood and can also be triggered by fatigue or boredom.

The current record for the most yawns in a day is not officially documented as it is not a widely recognized category for record-keeping. The number of yawns a person can do in a day can vary depending on individual factors such as fatigue, boredom, and brain activity.

I did some research into this and it appears as though a deficiency in Magnesium can cause the type symptoms you are mentioning. I had the same type chest pains after yawning for a number of years. The pain and frequency increases dramatically whenever I would take in large stimulates like too much caffeine or weight lifting energy supplements. My doctors told me to stop taking the energy pills so I did. However, the problem still persisted. When I researched another issue I had I came across information that seemed to tie it all together. It appears much of the pain was due to magnesium deficiency. Within a week of taking magnesium, I felt the symptom starting to quickly go away! Since taking the magnesium, it has eliminated those chest pains altogether when I yawn! I had seen the doctor several times, had ex-rays for obstructions, stopped drinking caffeinated drinks (all good things) but it still persisted until I took the magnesium supplements.

Yes , when you yawn you take a slow and deep breath that brings more oxygen to the brain. the oxygen gives your brain cells a little wake up call.

Yawning when you see someone else yawn is thought to be a form of social bonding or empathy. It may be an unconscious response triggered by seeing someone you are connected to engage in a behavior, leading to a contagious yawning effect.

Yes, it is sort of a pass on.

Lets say you yawn && there is a person beside you, eventually he/she would yawn because not of boredom... my teacher told me a month ago why but I forgot but pretty much it's contagious(:

you may have a severe cold or flue

get more/better sleep

to suppress a yawn, when you feel it coming, take a few deep breaths through your nose.

becaue when you see soeone yawn it makes ur brain think u need 2 yawn.

or

yawning is due to the fact you are breathing slower and not taking in enough oxygen

yes when you are tired and your body is trying to stay awake it yawns
