Mouth breathing can have several underlying causes, including nasal congestion, allergies, or poor breathing habits. It occurs when individuals breathe through their mouth rather than their nose, leading to various health risks. Chronic mouth breathing can cause dry mouth, bad breath, and an increased risk of oral infections. It may also contribute to poor sleep quality, snoring, and even affect jaw development in children. Addressing mouth breathing through solutions like the Buteyko Breathing Method, nasal irrigation, or seeking medical advice can help restore proper breathing patterns. Understanding the causes and risks is essential to improving overall health and well-being.
