In our current theme of yogic breathing and helping with breathing diseases, here’s an interesting article:
When you practice the deep breathing technique like in Munshi’s video, you are pushing air into your lungs, Patel said. As you hold your breath at the end of the exhale, you are “splinting open the air sac, increasing the surface area for gas exchange within your lungs,” she explained, adding that this helps to open collapsed air sacs in the lungs and improve oxygen levels in the body.
Ventilators perform a similar function in patients who are not healthy enough to breathe efficiently on their own, Patel said.
