Patients with pulmonary fibrosis should pay attention to the prevention of infection, and be more careful during the seasonal changes or flu season, live a regular life, and treat any manifestations of cold and flu as soon as possible. Be cautious about taking health supplements, especially some tonic ones, such as ginseng, wolfberry and so on, because in terms of Chinese medicine, although most patients with pulmonary fibrosis do have a deficiency of positive qi, there are differences in partial qi deficiency, yin deficiency and yang deficiency, and most of them also have phlegm, blood stasis and other evil qi, so they cannot blindly supplement. The diet should be nutritionally balanced and generally speaking not too cold or too spicy. Appropriate activities are desirable to circulate qi and blood and enhance physical fitness.
