In pursed lips breathing, you inhale through your nose and exhale slowly by pursing your lips. This breathing technique helps to keep airways open for a longer time so that you can remove the air trapped in your lungs by slowing down your breathing rate.
How to do it:
Step 1: Sit down in a comfortable position with your back straight and your hand placed on your thighs.
Step 2: Inhale through your nose for 2 counts. Try to fill your abdomen with the air, instead of your lungs.
Step 3: Purse or pucker your lips and breathe out slowly for 4 to 6 seconds.
