What Is Congestion? Symptoms, Causes & Treatments.
Breathing consists of two phases: breathing in (inhalation) and breathing out (exhalation). Breathing involves the movement of air into and out of the chest, and is also called ventilation. The term respiration relates to the exchange of gases in the lungs that happens when you breathe.1
The respiratory system works so that you breathe in and out comfortably at rest where the least effort is required to move air – and you’re probably not conscious of your breathing. When you exercise, you need to move more air. To do this you can take bigger breaths or breathe more quickly – usually both.2
What happens when our nose is congested?
Most of us think we get a blocked nose as a result of a build-up of excess much mucus. Actually, it’s the swelling of the nasal lining that leads to nasal congestion.
Having a blocked nose – with or without common cold symptoms – can be a drag. It not only interferes with our daytime activities, it can keep us awake at night, as well.3
