Cleansing of lung through natural ways will prevent you from getting severe respiratory problems. One of the best natural ways of cleansing the lung is by treating your lung with steam. This simply means you are inhaling the water vapor coming out when you place a bow of hot water in front of you. As the water vapor mixes with the air, it adds moisture and warmth to it, and when the air gets into your lung, it helps in clearing the mucus both in the lung and in the airways. Also, you can clean your lung when you cough.
Most times, when you cough, the excess mucus in your lung comes out. Doing this for a period of time will help you clear your lung and the airways. You can also clean your lung through exercise. Exercise will help increase your demand for oxygen, thereby increasing your breathing rate till it gets to normal. Exercise will allow you to get enough oxygen because it will make the airways to become wide.
