p2p种子搜索器2015:打哈欠能够让大脑降温

一份新的报道显示，哈欠能够帮助大脑保持凉爽，鼻窦在这个过程中所起的作用就像是风箱。

Yawning isn't triggered because you're bored, tired or need oxygen. Rather, yawning helps regulate the brain's temperature, according to Gary Hack, of the University of Maryland School of Dentistry, and Andrew Gallup, of Princeton University.

哈马里兰大学牙医学院的Gary Hack和普林斯顿大学的Andrew Gallup表示，哈欠并不是因为厌烦，疲倦或者需要氧气。相反，哈欠是用来帮助调节脑部的温度。

"The brain is exquisitely sensitive to temperature changes and therefore must be protected from overheating," they said in a University of Maryland news release. "Brains, like computers, operate best when they are cool."

“大脑对温度变化十分敏感，所以它不能过热。”他们在马里兰大学的通讯稿中说道。“大脑，就像电脑一样，当保持凉爽的时候能够维持最佳运行。”

During yawning, the walls of the maxillary sinuses (located in the cheeks on each side of the nose) flex like bellows and help with brain cooling, according to the researchers.

这两位研究人员表示，在打哈欠时，上颌窦的壁部（位于鼻子两边的脸颊上）像风箱一样弯曲，帮助大脑降温。

They noted that the actual function of sinuses is still the subject of debate, and this theory may help clarify their purpose.

他们注意到，鼻窦的真实作用还尚有争议，因此这项理论可能能够帮助揭示鼻窦的作用。

"Very little is understood about them, and little is agreed upon even by those who investigate them. Some scientists believe that they have no function at all," Hack said in the news release.

“人们对鼻窦几乎一无所知，而且研究者们也没有定论。一些科学家人们鼻窦其实是没有任何功能的。”Hack在这份新闻稿中说道。

The researchers said their theory that yawning helps cool the brain has medical implications. For example, excessive yawning often precedes seizures in people with epilepsy and pain in people with migraine headaches.

研究人员表示他们关于哈欠帮助大脑降温的理论能够有医疗方面的意义。例如，癫痫和偏头痛患者就会经常发现他们哈欠过多。

Doctors may be able to use excessive yawning as a way to identify patients with conditions that affect temperature regulation.

医生可以用哈欠过多作为确诊病人是否有影响温度调节的症状。

"Excessive yawning appears to be symptomatic of conditions that increase brain and/or core temperature, such as central nervous system damage and sleep deprivation," Gallup said in the news release.

“哈欠过多可能是大脑或者核心温度升高的症状之一。这可能是因为中央神经系统的损坏以及失眠造成的。”Gallup在这份新闻稿中说道。

The paper appears in the December issue of the journal Medical Hypotheses.

他们的论文发表在《Medical Hypotheses》12月刊中。
