Many people wonder why we should breathe through the nose, since the mouth also takes in air. However, it is worth remembering that the role of the nose goes beyond capturing air.
→ Why is it important to breathe through your nose?
The nose has adaptations that ensure greater respiratory efficiency. It is responsible, for example, for filtering substances and performs this process in two different ways:
- Presence of small hairs (vibrissae): the hairs present in the nose help filter some particles from the air. Usually the presence of these hairs guarantees protection against larger particles, such as insects.
- Presence of mucus: unlike hair, mucus is related to the retention of finer particles, such as dust and soot, and is also responsible for protecting against microorganisms. After retaining the particles by beating cilia, the mucus is carried to the pharynx, where it is swallowed or expelled.
It is worth noting, however, that the nose does not only guarantee that the air is filtered. This structure is also responsible for heating the air , since the cold air makes it difficult for the respiratory system to function and its humidification. Warming is achieved by the connective tissue present in the nasal cavity, which is largely vascularized (there are many blood vessels). Humidification, in turn, is due to the presence of glands that produce a serous secretion.
→ Can breathing through the mouth have consequences?
Breathing through the mouth can have bad consequences for the body.
Breathing through your mouth can, yes, have consequences. One of them is the change in the appearance of the face, as it can cause changes in the teeth, which are further forward, and in the palate, for example. In addition, it can also cause snoring, sleep apnea (disorder that causes breathing to stop during sleep) and tiredness. As the nose performs air filtration, breathing through the mouth also increases the risk of airway infections and increased cases of bronchitis.
→ Why do many people breathe through their mouths?
Mouth breathing is usually associated with factors that prevent adequate nose breathing. People with this type of breathing often face problems such as allergic rhinitis , adenoid enlargement, deviated septum, sinusitis and facial malformations. Therefore, when you notice inadequate breathing, it is essential to seek medical help to treat the problem
