There are also some people who sneeze when exposed to cold weather and suffer from winter illnesses like colds. At that time, the nasal cavity becomes swollen and becomes more sensitive than usual. Therefore, usually only a small impact of the environment is that people with colds can also sneeze.

The mechanism of sneezing is confirmed automatically , when an irritant comes into contact with the nasal mucosa, the nerves in the nasal cavity send a message to the lower part of the brain, also called the marrow. After that, the brain receives commands and activates the necessary effects that cause the body to sneeze.

Scientists calculate that, through many processes from taking air from the lungs, coordination of the chest muscles and diaphragm, sneezing can occur. Each time sneezing, the amount of mucus (saliva and mucus) released can range from 2,000 to 5,000 drops and the velocity can reach 112.6 - 160km / h. The impact range of mucus droplets is also quite remote when stretching up to 152.4cm.

However, there is an obvious fact that no one can sneeze without closing their eyes. So what is the reason and if it is possible to open your eyes, what will sneeze be and what happens?

How is the eye connected to the human skull?

There are many people who say mouth-to-mouth when sneezing when opening their eyes can make the eyes of a person sneeze out. But is that true? To find the answer you will have to understand how your eye is structured and how it is attached to the human skull.

The eyes also have a lot of special mechanisms, such as continuous flashing to wet the mucosa or cover it in time when detecting strange objects. The eye has a rather special structure with a small tube connecting the back of the nose. This also explains why when we cry often leads to runny nose. And also for that reason, people go back to prove that sneezing will also make people tears but not completely out. This is because the pressure from each sneeze can temporarily stop the tear glands from draining out.

However, there are actually many ways to explain why your eyes are closed while sneezing. One of the most recognized explanations is that the automatic response has no real purpose of the body.

Accordingly, the way the eyes are closed while sneezing has many similarities with the reflex mechanism when tapping lightly on the knee. And certainly, not only does eye muscles react to the effects of sneezing, but so are many other muscles in the human body.

In fact, there are many cases where people cannot control urine when sneezing leads to leakage. Thus, it is clear that there are certain effects from sneezing on the whole body of the human being that many different phenomena arise.
