Mouth breathing can significantly impact overall health and well-being, often leading to issues such as dry mouth, disrupted sleep, and reduced oxygen efficiency. Unlike nasal breathing, which filters and humidifies the air, mouth breathing bypasses these benefits, potentially causing problems like dental issues, snoring, and fatigue. It can also affect facial development in children. Understanding the causes of mouth breathing, such as nasal blockages or habits, is key to addressing it. Techniques like Buteyko breathing exercises can help retrain breathing patterns to promote nasal breathing. With proper guidance, transitioning to healthier breathing habits can enhance energy levels and overall health.
