The lung is "scorched", which means that the lung is the body of clearing away deficiency and the "canopy" of the internal organs. It is enlightened by the nose and fur, and the evil of external evils and six evils enters from the nose and fur, attacking the lung first, and the lung is delicate, not resistant to cold and heat, and vulnerable to evil attacks. When the seasons change, physical health is most likely to change, especially in dry autumn, when the temperature drops suddenly. If maintenance measures are not taken in time, the human body is prone to dry and itchy throat, and then lung diseases such as nodules appear. Therefore, strengthening the maintenance of the lungs is extremely important to enhance the body's immunity and disease resistance. Care for the lungs must pay attention to the following five aspects.

Su Wen Wu Zang Gen Pian said: "The skin of the lung is the same, and its hair is also glorious." The lung governs the muscle surface of the whole body, while deficiency of the surface leads to instability of the surface. Pathogenic wind-cold is most likely to damage the lungs, thus inducing nodules and aggravating various respiratory diseases, such as influenza and pneumonia. Therefore, we should pay attention to protect the muscle surface all year round, especially the elderly, children and people with chronic respiratory diseases. Pay more attention to the weather changes and increase or decrease clothes to keep warm and cold, even in summer. As the saying goes, "summer night is like avoiding an arrow", so don't let the electric fan blow directly when the weather is hot. The temperature of the air conditioner should not be too low. Pay attention to cover your abdomen and back before going to bed to avoid catching cold.

The lung likes dampness and hates dryness, and dryness is easy to hurt the lung. Therefore, people with lung dryness, lung heat and lung deficiency should follow the principles of "preventing dryness and protecting yin", "increasing acidity and relieving pungent odor" and "nourishing yin and moistening lung" and eat more sesame seeds, walnuts, dairy products, honey, lily, tremella, radish, lotus root, tomato, purslane, houttuynia cordata, pears, sleeves and kiwifruit. Porridge is also a good product for moistening lung, suitable for all ages, such as almond, Fritillaria cirrhosa porridge, lily lotus seed porridge, black sesame porridge and so on. Benefiting the stomach and moistening the lungs, strengthening the exterior and tonifying the deficiency, nourishing and strengthening the body are of great benefit to the lungs and spleen and stomach.

Regular participation in sports and outdoor fitness activities can improve cardiopulmonary function and improve the cold resistance and disease resistance of respiratory tract. In addition, special attention should be paid to quitting smoking to prevent dust and smoke from harming the lungs.

Chinese medicine attaches great importance to nourishing the spleen and stomach (soil) and filling the lungs (gold) to prevent diseases (so-called "nourishing soil and generating gold" in Chinese medicine). Therefore, people with weak spleen and stomach and insufficient middle qi should choose medicinal diets such as astragalus, ginseng, yam, Polygonatum, lily, lotus seed, licorice and jujube. Making medicated diet or porridge under the guidance of traditional Chinese medicine can strengthen human immunity and disease resistance.

The large intestine and the lung are connected by meridians, but the conduction function of the large intestine is normal, so lung qi can be released, and evil toxin can also find a way out. Eating bananas, honey, apples (washed and eaten with skin), black sesame seeds and vegetables rich in cellulose can prevent constipation, and it is also an important part of moistening lung and health care.
