Pursed-lips breathing can slow down your breathing, reducing your body's work by keeping your airways open longer. This makes it easier for lungs to function and improves the exchange of oxygen and carbon dioxide.
This breathing exercise is often easier for beginners than diaphragmatic breathing, and you can do it at home even if no one has showed you how. It can be practiced any time.
How to do it:
• Inhale slowly through your nostrils.
• Purse your lips, as if pouting or about to blow on something.
• Breathe out as slowly as possible through pursed lips. This should take at least twice as long as it did to breathe in.
