Benefits of Yawning

It seemed everyone had evaporated. However, the physiological mechanism, the purpose and meaning of the activities of this yawning is still a mystery for scientists.

According to Andrew Newberg, MD, associate professor of radiology at the University of Pennsylvania in Philadelphia, USA: Yawning has the effect of linkages with social awareness and feelings of empathy. It probably explains why yawning can be contagious. remember. Yawning can also regulate metabolism and cools the brain. This means that it can evaporate rid drowsiness and help you stay focused.

Actually, quite a lot of research trying to uncover the benefits of this evaporated. However, recent research conducted Dr.Adrian G.Guggisberg and published in the journal Neuroscience & Biobehavioral Reviews mention that none of these theories are proven.

Father of medicine Hippocrates stated evaporate will issue a "dirty air" and increase "good air" to the brain. In the modern view, the theory is defined as the activity of yawned will increase oxygen levels in the blood and reduce carbon dioxide.

According Guggisberg, if the theory is true, then there should be people who are exercising more often volatile. Moreover, people with lung or heart disease are often deprived of oxygen, it turns yawn frequency is the same as healthy people.

In a measurement of well-known high carbon dioxide healthy levels, not yawn more frequently. In fact there is no research to prove that the oxygen levels in the brain can change because of a yawn.

In other words, the research shows the best way to increase oxygen levels in the blood are more likely to inhale, not yawning.

Yawn frequency usually increases before and after waking. Feeling bored and tired can also cause us to yawn more frequently. Then came the hypothesis of yawning will make us more fresh.

When the researchers tried to prove through observation of brain activity using EEG (encephalography), did not find any improvement in brain feeling alert or central nervous system.

Guggisberg also mentions that yawning activity could not help equalize the pressure inside the ear because this function can be replaced by swallowing or chewing.

He thinks it's actually not contagious yawning as theory was recently revealed by researchers from the United States. "Solitary species was also evaporated, so it's not only humans and chimpanzees are social animals are yawning," he said.

Researchers from the University of Geneva, Switzerland, said yawning is a rich and complex phenomenon. Currently we are not able to uncover the mystery of the yawn, but later there will be experts who can explain to us what exactly the benefits of these activities seem trivial. However, according to my self yawning is a sign, a sign from the body that indicate you need more interesting activity than what you do now :). how about you?. http://the-benefits.blogspot.com
