What Is Pursed Lip Breathing?

Pursed lip breathing is a technique where you breathe in through your nose and slowly exhale through your mouth with your lips puckered. This exercise helps to slow down your breathing and improve the intake of oxygen in your lungs.

When you breathe, you're inhaling oxygen (which is used to make energy) and exhaling carbon dioxide (a gas released during cellular energy production)

Pursed lip breathing helps keep tiny air sacs in the lungs (called alveolar sacs) open longer, which allows for more oxygen to be absorbed. This improves oxygenation, making this technique useful for people with respiratory conditions like COPD.1

As COPD progresses, it becomes more difficult for people to control their oxygen levels. Practicing the pursed-lip breathing technique can help relieve shortness of breath and increase oxygen intake.
