Yawn makes people wiser?

Yawning is an activity that helps activate sinus catheterization, making the human brain more intelligent.

Previously, many people thought yawning was a sign of fatigue, lack of oxygen. But, Professor Gary Hack at the University of Maryland (USA) has proved that yawning helps people keep the 'cold head' . The finding is opening hope for treating insomnia patients, migraines and epilepsy.

According to Professor Hack and researcher Andrew Gallup of Princeton University (USA), the yawning action causes the maxillary sinus partitions to expand and contract like bellows, bringing air into the brain, helping to cool down. human brain. Because the structure is located on the cheekbone, the maxillary sinus is the largest sinus of the 4 pairs of sinus cavities on the head.

'Like a computer, the human brain is' extremely 'sensitive to temperature and needs to be kept in a cool state to be able to function effectively , ' Hack said.

In the 2002 study, Professor Hack and his team conducted a thorough analysis of a corpse and discovered that the posterior bulkhead of the maxillary sinuses was much thinner and softer than the knowledge recorded. again in medical books.

Since then, they believe that when the jaw moves, the sinus septum bends up, bringing air into the sinus cavities.

Combined with research by Gallup scientist in 2007 when giving the theory that yawning cool the brain. Also since 2007, Mr. Gallup has tested his hypothesis on both humans and animals.

For example, the team implanted tubes into the rat's brain and recorded changes in brain temperature before, during, and after yawning. As a result, the mouse brain temperature increased suddenly during the period before yawning, then gradually decreased and quickly decreased sharply to temperature before yawning.

That means yawning is triggered by an increase in brain temperature that actually promotes brain cooling.

Mr. Gallup also conducted experimental studies on 2 women with chronic chronic yawning. As a result, one of the two patients' body temperature increased before yawning and plummeted after yawning. This result is similar to the study of mouse brain temperature changed by yawning.

According to scientists, understanding the function of yawning is an effective way of diagnosing diseases such as migraines and epilepsy - two diseases that are caused by excessive yawning.

In addition, researchers at the University of Pittsburgh (USA) said that Professor Hack's finding will be a prerequisite for treating insomnia patients - the most common sleep disorder in America. . In particular, people with insomnia often do not have the ability to regulate body temperature, so they cannot lower their body temperature during sleep.
