A vibrant lung function ensures that abundant oxygen is transported from the air into the bloodstream while as much as carbon dioxide is released from the blood into the air. The lung capacity or vital capacity, a measurement of strength of respiration function, starts to decline around the age of 30.
When the lung function declines, one may experience shortness of breath, lack of desire of talking and of physical strength, and pale face etc., which are indications of the Qi deficiency of the lungs in the term of traditional Chinese medicine (TCM). Another common type of lung weakness in TCM is the lung Yin deficiency, which is shown as dry cough, dry and sore throat, hot palms and soles, and night sweat etc. The cough may even come up with a trace of blood. The lung Yin may be hurt by smoking.
