How you breathe has a significant impact on your quality of life. However for lifelong and habitual mouthbreathers, making the switch to nose breathing can be challenging. This community is to support people as they transition to nasal breathing.

"Mouth breathing is characterized by inhaling and exhaling primarily through the mouth and is considered to be an abnormal respiratory function. The nose has numerous functions: olfaction, sensation, mucociliary clearance, filtration, and immunological functions. The nose has the function of regulating air from cold to warm and humidifying the air during the nasal cycles of airflow dynamics. Nasal breathing cleans the air as it enters the body, produces nitric oxide (NO), and performs the same amount of work with less energy expended. Immunological functions of the nose produce mucus and secrete immunoglobulins. The nose has its own self-defense due to its coarse hairs and the secretions it creates. In addition, the nose protects the lungs from allergens, toxicants, and other bacteria through its immunologic properties."
