Sneezing: a protective reaction of the body

Sneezing is the body’s protective reaction to irritating agents that enter the nasal cavity. This reaction helps clear away caustic chemical fumes, dust, foreign bodies, mucus buildup, and other irritants that may enter the underlying respiratory tract.

When an irritant enters the nasal cavity, it acts on the sensory endings of the trigeminal nerve located in this area. In response to this, a reflexive deep breath occurs. The soft palate then rises and closes the internal nasal opening, which creates increased pressure in the chest cavity.

After this, the internal nasal opening suddenly opens and forced exhalation occurs through the nose. Together with the air flow, the substance that irritated the mucous membrane is removed.

Sneezing is an important protective reaction of the body that prevents irritants from entering the underlying respiratory tract. Without this reaction, the body would be more vulnerable to various infections and respiratory diseases.

In addition, sneezing can be a symptom of infectious diseases of the respiratory tract, such as a runny nose, flu, ARVI and others. In this case, sneezing contributes to the spread of pathogens, so it is important to take precautions for such diseases so as not to infect others.

To reduce the risk of infection, it is recommended to cover your nose and mouth with a disposable tissue or the crook of your elbow when sneezing. It is also important to practice good hand hygiene and avoid touching your face with dirty hands.

In conclusion, sneezing is an important defense mechanism of the body that helps get rid of irritants in the nasal cavity. However, in the case of respiratory infections, sneezing can spread pathogens, so precautions must be taken.

What is sneezing? Sneezing (sternutation) is a reflex process that occurs when receptors in the nose are activated. When air enters the nose through the nostrils, receptors on the lining of the nose begin to respond to irritants such as dust, dirt, pollen, chemicals and other allergens. The brain then sends a signal to the diaphragm, which begins to contract and push air out of the lungs through the vocal cords.

How does the reaction to a cold occur? When we feel the symptoms of a cold, our body tries to fight the infection. However, when an infection reaches deep into our lungs, our body responds by increasing the production of mucus in the larynx and bronchi. This mucus serves as a protective barrier that prevents the infection from spreading further.

But if the body's defense mechanisms are weakened due to other diseases, such as asthma or chronic respiratory diseases, then the protective mucus will not effectively resist infection. In this case, the person may begin to sneeze frequently to clear the infection from the respiratory tract.

Cold symptoms vary from person to person, but they all cause sneezing. A cold can cause the following symptoms:

1. Stuffy nostrils 2. Mucous discharge from the nose 3. Cough 4. Headache 5. Sore throat 6. Runny nose 7. Itching, swelling, redness of the skin 8. Fatigue 9. Increased body temperature

**The causes of sneezing can be different:** - Allergenic substances contained in house dust, animal sebum, cigarettes, street dust, etc.; - Psychogenic factors, including stress, anxiety, restlessness, negative emotions associated with psychological experiences; - Predisposition to allergies;

If sneezing occurs regularly and

Sneezing is a reflex action that occurs in response to contact of the respiratory tract with an irritant that causes irritation. A sneeze is the product of a process that includes an irritation phase, a defense phase, and a return to normal after the irritant disappears.
