Suddenly itchy nose, sneeze is about to hit, some people will turn their heads suddenly out of habit to avoid the embarrassment of splashing droplets. However, if the head is turned too suddenly, and the external force of turning and sneezing is added, the vertebral artery will be significantly stretched. If the artery itself happens to have certain defects, it may lead to arterial dissection and induce cerebral infarction. In addition, when you sneeze, the pharynx will be under great pressure, and the adjacent carotid artery will also be impacted. In particular, middle-aged and elderly people should consciously control the amplitude when sneezing, and it is not advisable to use excessive force. When sneezing, don’t turn your head too hard or too hard, just cover it with your elbow or a tissue. (Life Times)
