This affects the blood circulation of the lungs, which will cause a series of pulmonary dysfunction. Especially for people with chronic bronchitis and other lung diseases, if they are stimulated by some bad emotions for a long time, it is very likely to cause alveolar rupture, which is very harmful to lung health.

Illness comes from the mouth, and poor eating habits are also the main causes of lung lesions. Often eating roadside stalls, barbecue, fried food or spicy and irritating food in life will affect gastrointestinal health and indirectly damage the normal function of the lungs. Function.
