我们会在卡通片中看到睁眼打喷嚏却把眼珠子打飞的镜头。但现实生活中,我们在打喷嚏时,脸部数百块肌肉会得到有效放松,同时,眼睛本能闭上。那么打喷嚏时为什么会闭眼睛?这是一个很有意思的问题。其实,打喷嚏时要以很大的力量逐出气体,肺、口腔、鼻腔内都有很大的压力,不仅膈肌? We will see the cartoons with eyes open and sneeze but the eyeball flying shot. But in real life, when we sneeze, we can effectively relax hundreds of muscles in our face while keeping our eyes closed. Why sneeze when closed eyes? This is a very interesting question. In fact, sneezing with a great power to expel the gas, lungs, mouth, nasal cavity has a lot of pressure, not only the diaphragm?
