First of all, lungs are mainly used for breathing, so it is the key to judge whether lungs are healthy from people's breathing conditions. A normal person should breathe evenly and smoothly, but if the lungs are troubled by diseases, there will often be shortness of breath, poor breathing, chest tightness and shortness of breath, which is a major manifestation of lung problems, which may be caused by weakened lung function.
Secondly, the test of vital capacity. I believe that everyone has the problem of detecting vital capacity in school physical examination, so it is very important to detect lung health. The greater your vital capacity, the deeper your breathing, which also means that your exercise ability is relatively developed. The normal vital capacity of adults is about 4000ml. With the increase of age and the decrease of exercise, the vital capacity will gradually decrease.
Finally, from the perspective of people's faces, if you look pale, haggard and have purple lips, it is likely that there is something wrong with your lungs. Modern people are facing the hazards of second-hand smoke, smog, kitchen fumes, automobile exhaust and other exhaust gases. More or less, some toxins will accumulate in the lungs, and then slowly reflect on the skin surface, resulting in poor skin quality, whitening or yellowing of the face and other symptoms.
Whether a person's lungs are healthy or not can be effectively understood by combining the above three manifestations. In our daily life, we might as well try to do some such tests regularly, so as not to wait until there are serious problems in the lungs, and then it is too late to treat them. At the same time, if you can smoke less and exercise properly, it will be more beneficial to the health of your lungs.
