Mouth breathing

Mouth Breathing

Mouth breathing (/maʊθ 'bri:ðɪŋ/) is a type of respiration that occurs through the mouth rather than the nose.

Etymology

The term "mouth breathing" is derived from the English words "mouth" and "breathing". "Mouth" comes from the Old English "mūth", and "breathing" comes from the Old English "brǣþung", which means the act of inhaling and exhaling.

Definition

Mouth breathing refers to the act of inhaling and exhaling air primarily through the mouth. This can occur during strenuous physical activity, when the body requires a greater oxygen intake, or as a result of a medical condition such as nasal congestion or deviated septum.

Related Terms

Nasal Breathing: The process of breathing through the nose. Nasal breathing is considered healthier than mouth breathing as it filters, warms, and humidifies the air before it reaches the lungs.
Respiration: The process of inhaling oxygen and exhaling carbon dioxide. This is done through the nose in nasal breathing and through the mouth in mouth breathing.
Oxygen: A chemical element that is vital for most forms of life. It is inhaled during respiration and used by the body's cells in the process of metabolism.
Carbon Dioxide: A waste product produced by the body's cells during metabolism. It is exhaled during respiration.

Health Implications

Chronic mouth breathing can lead to a number of health issues, including dry mouth, bad breath, and higher risk of respiratory infection. It can also cause long-term issues such as improper facial development in children, sleep disturbances, and cardiovascular problems.
