Why often sneeze?

Sneezing is a protective reflex of the body, associated with the removal of foreign particles from the respiratory tract. Why often sneeze? There can be several reasons.

I often sneeze: causes

First of all, it is necessary to understand why a personsneezes at all. Bacteria, dust, allergens, settling on the nasal mucosa, irritate the nerve endings, and the corresponding signal is transmitted to the brain. As a result of a sharp contraction of the muscles of the chest, air from the lungs is pushed outward through the nose, sweeping away all obstacles in its path. That's why after a sneeze, a person is relieved.

Frequent sneezing can be explained by several factors.

1. Viral and bacterial infections. One of the answers to the question "Why do I often sneeze?" Is a cold. With a cold illness, sneezing is accompanied by an abundant discharge of mucus from the nose, difficulty breathing, itching in the nose. Frequent sneezing is typical for such diseases as ARVI, influenza, measles, chicken pox. Sneezing can also provoke bacteria that have settled in the trachea, bronchi, and the nasopharynx.
2. Allergy. In the spring-autumn period, a large number of people seek help from allergists, because at this time there is an active flowering of plants. As an allergen can act not only flower pollen, but also animal hair, home dust particles and mold, tobacco smoke and other specific smells.
3. Pregnancy. During pregnancy, hormonal changes occur in the body of women, which can provoke the appearance of a cold. There is such a thing as "rhinitis of pregnant women". As a rule, the disease manifests itself several weeks before the birth and can threaten with serious complications, since shortness of breath affects the work of the heart and lungs. Difficulty of treatment consists in impossibility to use vasodilators because of their danger to the fetus.
4. Sneezing newborns. If you exclude a cold, sneezing in babies can be caused by bright light or insufficiently moist air in the room. Some babies sneeze during feeding, as sucking movements irritate the mucous membrane of the not fully formed nasopharynx. In addition, the baby's nose produces a large amount of mucus, which, forming crusts, causes an involuntary sneeze.
