What is sneezing? Why do we sneeze?

A sneeze is a spasm that is caused by various causes, from exposure to the sun to something very strong, passing through a cold or also by sexual excitement. The tingling sensation in the nose Which can not be suppressed by anything in the world always ends in sneezing.

Despite being very common, science still does not know why it occurs. Although they do have some ideas about it. That it is a reflex act is the first hypothesis but, at the same time, it may have conscious control and we could come to repress it.

Sneezing reflex consists of two phases : The first is called spasmodic inspiratory and the second is called expiratory, both nasal and oral. The consequence of this mechanism is the expulsion of air and saliva (also viruses, germs and bacteria) at a speed that oscillates between 70 and 130 km per hour. The particles can reach up to 8 meters.

Sneezing Facts

When someone sneezes, those around them say"Jesus"or"Health,"depending on the country and the tradition.

In Spain, after an epidemic in 1881, it used to say"God, Jesus, Mary and Joseph help you". At present we have abbreviated to"Health"and"Jesus".

Sneezing originates when the respiratory epithelium (the layer of cells lining the nose) is irritated and gives the order to brain So that it initiates its reflex act of expelling that substance that is entering in the organism.
