Yawn much sleep helps memory

Scientists from Princeton University have discovered that a big yawn can adjust the temperature and prevent overheating of the brain condition.

In the winter in Tucson, Arizona, Professor Andrew Gallup and the team have arranged for 80 people chosen at random to look at pictures of people are yawning and record their responses. Then, this test is done in a similar way in the summer. The results showed that in the winter, 1/2 of the people involved have acted yawn while in summer, the figure is only 1/4.

From there, the team found that cooling the brain yawn. Then you will surely want more brain cooling in summer by yawn?

However, in theory, yawn brain cooling via heat exchanger with cold air from outside. This process will therefore have no effect on a very hot summer day. Professor Gallup said: "the effects will reverse when the ambient temperature exceeds body temperature".

Nearly 40% of the participants (in both summer and winter) yawn within the first five minutes, but the percentage of those who yawn at the summer quickly reduced to below 10 percent after that. Results in contrast to the observations in the winter. "This is the first report suggests that yawning frequency change from season to season to another," Gallup said.

This may help explain why people often become confused and disoriented in extreme temperature conditions.

The research contributes to knowledge systems Physiology base of people and provides an understanding of the conditions for the development of the disease in the nerve as well as epilepsy.

Yawn also helps prevent sleepiness. This discovery caused no little surprise for us, while most people still think the yawn will increase the feeling of drowsiness. Yawning helps the facial muscles shrink, which increases the amount of blood flowing through the arteries leading to the brain. According to science, this can increase alertness, ability to maintain the capacity to concentrate.

Enhance the fun

Enhance the fun, enthusiastic, pleased, even has the ability to help ease the pain.

When we yawn, the amount will rise to dopamine, which helps the body produce more oxytoxin. This is a type of hormone that enhances the fun, enthusiastic, pleased, even has the ability to help ease the pain. The substance is active more and more, the more you tend to yawn more.

In particular, the yawn to sleep longer has the ability to "spread". When you see someone else yawn, you often have the feeling like ... yawn. This chain reaction occurs is similar to when we laugh because it created the reflection, promote you in response to a status of the behavior or feelings from other people and it also bring adverse effects not least when we laugh?!

Re-enable the body

Yawning is a way to reset the biological clock operating under the "standard" of the body.

People who tend to yawn to sleep much more than regular people up late, wake up late, who just ill wake up. .. The cause of this is because of their biological clock has been skewed. And yawn is a way to reset the biological clock operating under the "standard" of the body.

On the biological aspects, yawn sleep will help us stir neuromuscular system and created the evolution in the brain stem. It helps regulate the body's biological rhythms or is the 24 hour cycle-active status is the normal biology of each person, and alleviate the effects of the biological disorders in the body. That is also why we yawn when regular sleep to those areas with the time zone change.

Mental stimulation

When to do these jobs require a high concentration, we must consume a lot of energy. Hence the spirit prone to fatigue, adjusting, inefficient work ... This is also the reason you often tend to yawn to sleep a lot when stressed, tired.

The cause of this is because when the body and spirit are tired of mind, we need a break and reactivate. Yawn to sleep is a way to improve this. It helps stimulate the nerve area dominates the ability to work, increasing the oxygen supply to the brain, while helping the spirit be relaxing ... Moreover, it also helps them maintain memory more efficiently.=
