To understand the importance of keeping the nasal passages open, we need to know more about the nose and its functions.
The nose and the nasal cavities make up the main airway linking the respiratory system to the outside environment. The nose is a facial process made up of cartilage, bone, muscles and skin; it supports and protects the anterior portions of the nasal cavities.
Unimpaired nose breathing is therefore important for keeping the bronchi and the lungs healthy.
Nasal congestion is a problem which should be dealt with quickly. But it is important not to use aggressive substances, since these can damage the delicate mucous membranes of the airways.
The nasal turbinates are elongated bony structures covered by the nasal mucosa. They increase the surface area of the nasal cavity and heat and humidify the air, filtering it and making its flow less turbulent.
