Huangdi Neijing holds that human lungs correspond to autumn. In autumn, the summer heat gradually disappears, and the dryness is rampant, which is easy to consume body fluids. The lung governs qi, regulates breathing, opens the nose, and covers the fur. The function of lung is closely related to breathing. If the nose is affected by external pathogens, it may hurt the lungs. Dry is easy to hurt the lungs. In autumn, the human body is prone to dry mouth and throat, dry cough and less phlegm. In autumn, lung yin is often damaged, especially those who are prone to chronic bronchitis, asthma and other diseases. Make up lung yin and lung qi in autumn.
Late autumn is also the season of cardiovascular diseases in middle-aged and elderly people. It is suggested that patients with cardiovascular diseases should pay attention to adding clothes according to weather changes.
