1, observe the lips.
In daily life, healthy people's lips are very rosy and shiny. If your lung function is not very good, then your lips often look a little purple. The reason why this happens is mainly because the body is in a state of excessive hypoxia for a long time, which easily leads to purple mouth.
Step 2 hold your breath
In the process of holding your breath, focus on your lungs and feel if there is any abnormality in your lungs to see if you can hold your breath for more than 30 seconds. If you feel dull pain in your lungs when you hold your breath, it is probably caused by some abnormalities in your lungs.
After holding your breath, try to take another deep breath. At this time, focus on the lungs, especially when inhaling, and feel whether there is pain in the lungs. If there is, it may be a lung injury.
Step 3: Climb the stairs
In the case of normal physical performance, we can climb the stairs at a constant speed and observe our breathing in the process. If you don't have shortness of breath, chest tightness and shortness of breath, your lung function is still very healthy. However, if you find that you have shortness of breath and chest tightness before the comparison, it may be a signal that your lung function is getting worse.
Extended data:
If there is something wrong with the lungs, there will be three "abnormal states" in the body.
1, dry and yellow skin.
Winter is the high season of dry skin, but if dull and yellow appear at the same time, it is related to lung damage. Traditional Chinese medicine believes that excessive lung toxins will first affect the skin, so abnormal dullness and dryness must be alert to changes in lung health.
2. The nose is black
When the lungs are damaged, toxins will accumulate. When the toxin is beyond its own metabolic range and cannot be excreted in time, it will appear on the nose, leading to black nose.
3. Defecation weakness
Our five internal organs are interlinked, and lung qi deficiency can easily lead to spleen qi deficiency, which in turn affects the digestive function and peristalsis function of the large intestine, leading to weakness of the large intestine and poor defecation. To put it simply, I obviously want to defecate, but it is difficult to excrete normally because of lack of strength.
