Why yawning is no insult... it's a sign that someone really cares Yawn: Scientists believe far from being a sign of boredom the gesture can signal empathy. When your friend stifles a yawn as you chat, don’t be offended. Instead, take it as a compliment. For, far from being a sign of boredom, yawning may signal empathy. Scientists believe that contagious yawning – yawning after someone else does – is a sign of being keenly interested in the first person’s thoughts and feelings. This is the theory of Italian researchers who observed more than 100 men and women from four continents as they went to work, ate in restaurants and sat in waiting rooms.

Is yawning contagious? If so, why? What's the evidence? The evolution theory: Some think that yawning began with our ancestors, who used yawning to show their teeth and intimidate others. An offshoot of this theory is the idea that yawning developed from early man as a signal for us to change activities [source: University of Washington]. The boredom theory: Although we do tend to yawn when bored or tired, this theory doesn't explain why Olympic athletes yawn right before they compete in their event or why dogs tend to yawn just before they attack.

What makes us yawn? 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. Now that we know what a yawn is, let's look at what causes us to do it.hen you inhale, the air taken in is filling your lungs. Your abdominal muscles flex, and your diaphragm is pushed down.

This contagious yawning has also been observed in chimpanzees, dogs, and can occur across species.nother 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.

What Causes A Yawn? Excessive Yawning. Excessive yawning is more than a theory, it’s actually an indication of something more serious called a vasovagal reaction. The yawning occurs as a response to the vagus nerve, which is the longest cranial nerve. When this nerve acts upon the blood vessels, it causes the body to yawn.This is usually a sign of a heart problem to come such as a heart attack or an aortic dissection, which is a separation of the aortal walls.hen this nerve acts upon the blood vessels, it causes the body to yawn.

What Should I Know About Excessive Yawning? When the yawn comes on he must keep the pressure in the rear of his jaws and swallow the yawn. Excessive yawning, caused by sleepiness, can be counteracted by drinking lots of water. Dehydration is a big cause of fatigue. When a person drinks a lot of water, the yawning will cease. Every time the urge to yawn is strong, drink a big gulp of water and the yawn will pass.

- A yawn is a reflex consisting of the simultaneous inhalation of air and the stretching of the eardrums, followed by an exhalation of breath.Yawning (oscitation) most often occurs in adults immediately before and after sleep, during tedious activities and as a result of its contagious quality.nother hypothesis is that yawns are caused by the same chemicals (neurotransmitters) in the brain that affect emotions, mood, appetite, and other phenomena.

Why do we yawn? By the 17th and 18th centuries scientists were challenging the Hippocratic theories of yawning. These new theories focused on the circulatory system, suggesting that yawning causes an increase in blood pressure, heart rate and oxygen in the blood, which in turn improves motor function and alertness.

Why Is Yawning Contagious? It means that yawning might act to draw brain-soothing ambient air in through the nose and mouth. So far, scientists have observed “contagious yawning” in chimpanzees, humans, baboons, bonobos, wolves, and, to a certain extent, dogs and budgies.

- Sounds good, but other studies have shown that breathing more oxygen does not decrease yawning. Likewise, breathing more carbon dioxide does not increase yawning. Hmmm. Now what? Another theory is that yawning stretches the lungs and lung tissue. Stretching and yawning may be a way to flex muscles and joints, increase heart rate, and feel more awake. Other people believe that yawning is a protective reflex to redistribute the oil-like substance called surfactant (say: sur-FAK-tint) that helps keep lungs lubricated inside and keeps them from collapsing.

- Listen to Monty's Answer: Read Monty's Answer: It certainly does, and it has a critical meaning when dealing with horses. The act of yawning is to take in oxygen. One element of tiring is starving the brain of oxygen. During exertion and tension we assign oxygen to muscles needed for work. Horses in their quest for survival will enter periods of extreme concern and rob the brain severely.

Why do we yawn? In humans, yawning can start as early as 20 weeks after conception. A yawn is a coordinated movement of the thoracic muscles in the chest, diaphragm, larynx in the throat, and palate in the mouth. By yawning, we help distribute surfactant (wetting agent) to coat the alveoli (tiny air sacs) in the lungs. Generally speaking, we cannot yawn on command.
