The lungs play an important role in the life and daily activities of humans, ensuring the respiratory process by exchanging gases: bringing oxygen from the air into the pulmonary veins and carbon dioxide from the pulmonary arteries out. In addition, the lungs also have some secondary functions such as assisting in the metabolism of certain biochemicals and filtering some toxins in the blood.
However, the lungs are vulnerable to many factors, both objective and subjective. In harsh respiratory conditions such as high humidity, extremely low temperatures, dryness, frequent seasonal changes of bacteria/viruses, or polluted environments, we need to pay attention to protecting our lungs.
To assess the condition of your lungs, you can rely on your breathing rate, some exercises to evaluate respiratory function, and any abnormal signs on your face.
These three facial signs below may indicate that the lungs are accumulating too many toxins, and lung diseases may be silently developing.
Black nose
The lungs are the main respiratory organ, mainly transporting oxygen from the outside into the bloodstream through the nostrils to excrete waste gases from the lungs. When the lungs accumulate many toxins and are damaged, the nose also undergoes some abnormalities.
The most commonly seen abnormality is a black nostril, which accumulates a lot of waste and can cause discomfort or itching. In addition, there will be more nose hair, which is blacker and stiffer as a way for the body to try to filter the air better before it enters the lungs.
The color of the nose may also be darker, with more blackheads in the nose area, due to weakened lungs that are unable to eliminate toxins from the body.
Dark or blue lips
In healthy individuals, the color of the lips is usually rosy. But if the lungs accumulate many toxins, the lips will gradually turn dark or purple. The reason is that oxygen needs to be delivered to different tissues through the lungs, so once toxins from the lungs hinder the oxygen transportation process, pigmentation in the lip capillaries will accumulate and create unusual discoloration on the lips.
In winter, environmental factors can also cause a temporary darkening of the lips due to extreme cold. However, if the temperature is normal and the lips are still pale or slightly blue, you should be careful about the health of your heart and lungs. This is because when red blood cells weaken, the blood secretes a blue pigment that changes the color of your lips to a strange blue hue. It is best to seek medical attention and treatment early.
Dull facial skin
Moist and radiant skin indicates the low accumulation of toxins in the body. However, if the skin becomes dull, lifeless, and lacks vitality, it indicates that blood circulation is not smooth and the lungs are accumulating a lot of toxins that settle on the surface of the skin. This is particularly noticeable in the facial area, around the eyes, and near the nostrils.
In addition, the accumulation of toxins in the lungs and the decrease in lung function also make the skin prone to poor blood circulation and lack of oxygen. As a result, the skin not only changes color but also ages faster, even exhibiting abnormal swelling and black spots under the skin.
To protect your lungs, you should maintain a healthy lifestyle such as exercising, avoiding smoking, drinking enough water, managing stress, practicing deep breathing, maintaining cleanliness, eating a balanced diet, and regularly getting health check-ups.
