There is no person on our planet who has never coughed or sneezed. Probably, each person experienced unpleasant sensations when, during a conversation or, for example, laughing during a meal, food got into the respiratory tract or, as they call it, “not in the right throat”. The person immediately begins to clear his throat. The situation is similar with the nasal cavity - if we breathe in any dust particles, we immediately begin to sneeze, and sometimes more than once! Of course, such situations cannot be called comfortable, but you should not think about their futility. The thing is that coughing and sneezing are very useful protective functions of our body, without which we would have had a hard time. So let's figure out what is the matter here, why do people sneeze and cough.
Why do people cough?
A deep short breath, followed by a rather sharp jerky exhalation through the mouth - this is how our cough can be described.
This is the protective function of our body: when coughing from the mouth, for example, bread crumbs that are undesirable for us, which, as the people say, “get in the wrong throat”, can fly out. When we get sick, we hate our cough, but in vain ... Here he also helps us! Only in this case, he does not “throw out” from our upper respiratory tract food, but the mucus that accumulates there. Do not forget that a strong cough is an indicator of the unsatisfactory condition of our bronchi or
respiratory throat. When the disease recedes, then, for obvious reasons, the mucus ceases to form, accumulate, which means that the cough also disappears. We conclude that coughing is a double-edged sword: on the one hand, this is a serious signal about poor health, and on the other, an assistant in recovery.
Why do people sneeze ?
Sneezing is also a protective function of the body, ridding our nasal passages of mucus and various dust particles. In general terms, this happens due to the hairs that completely cover the nasal passage, preventing dust and other undesirable muck from getting into the lungs. But what are the reasons why people sneeze?
The reasons that cause this protective reflex are complete, some of them may be individual for this or that person. For example, sometimes we sneeze from dust or pungent odors that irritate the
olfactory nasal
receptors . It is they who begin to tickle in the nose just before the sneeze: the foreign body that gets into the nose begins to irritate the nerve receptors, the signal enters the brain, which, in turn, sends a “command” to sneeze. The whole operation takes as much as a fraction of a second! Another
reason why a person sneezes
often is a very bright light. It can be either a bright light bulb or the sun's rays.
Why do people sneeze in the sun
For the question "why do people sneeze in bright light"
- no one can answer yet. There are several explanations for this, one of which says that in the "center of events" is the
optic nerve and nasal
mucosa , which are directly connected with the nerves. When we look at bright light, the impulse from pupil irritation is transmitted through the brain to the nerves of the nasal mucosa - sneezing occurs. According to another theory, our pupils are forced to sharply narrow in the sun, which leads to increased production of
lacrimal glands. Tears, in turn, falling into the nose irritate its mucous membrane, and again we sneeze.
Be that as it may, know that coughing and sneezing are only good for us. Never interfere with the natural processes of our body, trying hard to restrain these protective reflexes - sneeze and cough with all your heart! Be healthy!
