Mouth breathing occurs when individuals breathe primarily through their mouths instead of their noses. This common habit can lead to various health issues, including dry mouth, bad breath, and an increased risk of dental problems. Mouth breathing can also affect sleep quality, contributing to conditions like snoring and sleep apnea. Additionally, it may hinder proper facial development in children, leading to misalignment of teeth and jaws. Addressing mouth breathing is essential for improving overall health and well-being. Techniques like the Buteyko Breathing Method encourage nasal breathing, which promotes better oxygenation, enhances relaxation, and supports optimal oral and respiratory function.
