szájlégzés

Mouth breathing, known in Hungarian as szájlégzés, refers to the habitual practice of breathing through the mouth rather than the nose. While occasional mouth breathing can be a normal response to exertion or nasal congestion, chronic szájlégzés can be associated with various health and developmental concerns.

The primary function of nasal breathing is to filter, warm, and humidify inhaled air before it reaches the lungs. The nasal passages are lined with tiny hairs called cilia and mucus, which trap dust, allergens, and pathogens. When breathing through the mouth, this natural defense mechanism is bypassed, potentially leading to increased exposure to airborne irritants and a higher risk of infections. Furthermore, nasal breathing contributes to proper facial and dental development, particularly in children. The tongue resting on the roof of the mouth during nasal breathing helps to shape the palate and support the development of the dental arches. Mouth breathing, conversely, can lead to a collapse of the tongue position, potentially contributing to an underdeveloped upper jaw, crowded teeth, and an altered facial structure over time, sometimes referred to as "adenoid facies."

Common causes of persistent szájlégzés include nasal obstruction due to allergies, enlarged adenoids or tonsils, deviated septums, or chronic sinusitis. In some cases, it can also be a learned habit. Symptoms associated with szájlégzés can include dry mouth, bad breath, snoring, disrupted sleep, and increased susceptibility to respiratory infections. Identifying and addressing the underlying cause is crucial for managing chronic mouth breathing and preventing potential long-term consequences.
