WHY DO PEOPLE YAWN OR GAPE?
To Yawn is contagious, we know that. But why did people Yawn? Yawning is also so common that we are barely standing by what the reason is that we Yawn . Most people think it is due to fatigue or boredom, but reality may be more complex and mysterious.
When did people gap?
Scientists agree that we mainly gape (or yawn) at:
Gnomes or Yawning are usually associated with fatigue or sleepiness. Scientists have shown that gape occur the most often during the hours before falling asleep and just after you wake up.
Like fatigue, Yawning seem inseparably linked to situations in which we are bored or insufficiently stimulated. The boredom hypothesis was demonstrated in an experiment that allowed students to 30 minutes of a television test bar pattern while another group watched music videos for 30 minutes. The first group went on average 70% more. This confirmed the conviction that people Yawning more uninteresting about interesting, stimulating events.
5 possible causes of yawn
In 2010, an international congress was devoted to the mystery of Yawning in psychology and diseases in Paris. There are 5 possible explanations why people formulated gaps and yawns to further investigate:
1.Yawning causes more air in the lungs
Globally, this ghost is a mechanism of the body to get more oxygen and breathe more CO2.Although in 1987 this theory was extensively tested, it appeared that there was no connection between higher CO2 levels and more gaps. yawning stretches the lungs. By Yawning , the body prevents atelectase from occurring. Atelectase or longatelectase is a condition in which (a part of) the lung does not get air and thus coincides (collaps). also stimulates the production of surfactant, a substance in the lungs that helps keep the lungs open.
2. Gaping cools the brain
One of the most popular theories of recent years is that we are gonna cool our brains when they overheat them. There are also two studies that support this. A study showed that when cold elements are applied to the head one almost stops Yawning. The other study found that the frequency of Yawns changed with the seasons and that we jumped faster when the outside temperature is higher than our body temperature.
3. Cortisol and neurological disorders
Yawning may also be related to the cortisol level in our blood and to some neurological conditions such as multiple sclerosis and cerebral hemorrhage.
4. Gape as a social phenomenon
In recent years, research into the causes of Yawning has been less focused on the physical statements, but focuses more on the possibility that Yawn have a social, communicative reason. It seems that Yawns are infectious. The closer you are emotionally close together and the greater the empathy you feel for someone, the more intrusive is the ghost for the other.This applies especially to good friends and relatives.Yawning is also contagious for animals. In a 2007 study, 21 of 29 dogs found out that they were showing videos of yawning.
5. Gapen is an invitation to sex
researcher Wolter Seuntjens graduated from the Free University cum laude on the dissertation ‘On Yawning or The Hidden Sexuality of the Human Yawn’. His research was above all a systematic andcyclopaedic overview of all available knowledge about yawning.But he discovered that yawns may also have a relationship with sex. Patients from the American sex barologist Barbara Keesling reported that during the freedom an orgasm was regularly accompanied by yawn – to the partner’s dissatisfaction. German superstition says that when a young man and his girlfriend get together, there’s more to it than sympathy alone. “A hundred times a day, I’m walking and I’m stretching because my lady is the best of all,” sang a French troubadour in the twelfth century. Seuntjens: “yawn , say these examples, is body language for erotic interest, ranging from sensual sympathy to pure humor.” Said Seuntjens in an interview in the NRC. Seuntjens is also author of the book yawn ! The Exploration of the Gull
Unfortunately, there is no unambiguous answer to the question: Why did people die? People are suffering from fatigue and boredom. But the precise function and infectiveness of yawning in the social field is not yet clear. There are still many questions left unanswered. Maybe yawns are indicative of latent disease? Or is yawning just a remnant of our evolution? Maybe we’re gonna go out of our minds. More research is necessary.
