In through the nose, out through pursed lips as if through a straw — the breathing technique respiratory medicine actually prescribes.
Pursed lip breathing is one of the most clinically validated breathing techniques in medicine, recommended by the American Lung Association for people with COPD, asthma, and other respiratory conditions. By exhaling through slightly pursed lips—as if blowing through a straw—you create back pressure that keeps the airways open longer, preventing them from collapsing prematurely. This allows trapped air to escape from the lungs more completely, improving the efficiency of each breath. Even for healthy individuals, the technique slows the breathing rate, improves oxygen-CO₂ exchange, and promotes a sense of calm control over the breath.
American Lung Association recommended. Clinically proven to improve oxygen exchange and reduce shortness of breath.
