We humans are one of nature’s greatest works of art. Our body is incredible, it is a real machine and it needs everything to be working perfectly. We know that only in this way can we stay alive. It cannot be denied that everything that exists within us is indeed very impressive.
Our body has several and several reactions throughout our life, most of the time, these reactions are involuntary, as is the case with sneezing, but after all, why do we sneeze? If you have already asked yourself this question, keep reading, as we have the answer and we will reveal it right now.
Since the Roman empire, we have used to say “health” when someone sneezes. This happens because it is a way of expressing a desire for well-being for the person who is sneezing. In ancient times, sneezing was considered a sign of some serious illness, but with the evolution of medicine, we found that it is not always so.
Today we know that sneezing can be associated with the flu or allergy, for example, in both cases we can take medication to get better as soon as possible. In all cases, we can consult a doctor so that he prescribes the ideal medicine, so that we will not have other reactions.
The sneeze itself is an involuntary reaction of our organism, which serves to expel microorganisms present in our airways, whether in the mouth, nose and even in the throat. These microorganisms can be viruses or bacteria that can be related to colds and flu, or particles like pollen or dust.
We cannot control sneezing, as it happens practically “out of the blue” and we cannot predict it. Sneezing is extremely important for our health, as it eliminates the organisms that are causing us harm from our airways. In addition, it also eliminates organisms that trigger allergy, so we can say that sneezing helps to protect our body.
When the trigeminal nerve identifies the presence of microorganisms or irritating particles in our body, it commands commands the contraction of muscles in the back and abdomen, chest and ribs. In this way, our lungs are filled with plenty of air, then that air is expelled in a single time and we make the famous “atchim” sound.
The speed with which the air leaves is so high that it can reach more than 120 km per hour, so you can see that we could not resist this impulse. It is worth remembering that it is not recommended to try to prevent sneezing, as the pressure of the air that would leave, ends up causing vertigo and may even rupture the eardrum.

There are those who sneeze when they look at the sun, this is because when the intense sunlight hits our eyes directly, it ends up causing a mess in our nervous system. Thus, the optic nerve that carries signals to the brain is stimulated. As the optic nerve is very close to the trigeminal nerve, the wrong stimulus ends up causing the sneeze.
