In traditional Chinese medicine (TCM), it is said that “the lungs govern the body’s qi.” In TCM, qi refers to the vital energy that sustains the entire body. When lung function is strong, oxygen circulates efficiently, and the body feels energized.
TCM describes the body’s immune defense as “wei-defensive qi,” which is closely linked to lung health. When the lungs are weak (lung qi deficiency), wei-defensive qi also declines, making a person more prone to colds, coughs, and runny noses.
