9 Poses Yoga For Cough and Phlem In Chest (Medicinal Yoga)

Increase endurance.Over time, working out can help your airways build up tolerance to exercise. This makes it easier for your lungs to perform activities that usually make you winded, like walking up stairs.
Reduce inflammation.Though asthma inflames the airways, regular exercise can actually decrease inflammation. It works by reducing inflammatory proteins, which improves how your airways respond to exercise.
Improve lung capacity.The more you work out, the more your lungs get used to consuming oxygen. This decreases how hard your body must work to breathe on a daily basis.
Strengthen muscle.When your muscles are strong, the body functions more efficiently during everyday activities.
Improve cardiovascular fitness.Exercise improves the overall conditioning of the heart, improving blood flow and the delivery of oxygen.
