According to traditional Chinese medicine, the lung, which belongs to the five internal organs, is known as "Jiao Xuan". It has poor adaptability to the unpredictable weather in spring, with sudden changes in temperature and intermittent rain. It has weak resistance and is highly vulnerable to cold pathogen invasion, leading to lung deficiency and causing pneumonia. According to clinical observations, if the elderly show the following conditions, they should be highly vigilant: First, unexplained mental atrophy, loss of appetite or being bedridden; The second is that after a cold, it persists and does not heal, presenting symptoms such as accelerated breathing, flushed complexion, and cyanosis of the lips. Thirdly, in the short term, the eye sockets sink in, the pulse is weak, blood pressure drops, and the hands and feet feel cold. The fourth is physical fatigue, apathy and excessive sleepiness. The fifth is that patients with "chronic bronchitis" and other conditions experience shortness of breath, with a large amount of yellow phlegm or mixed with blood streaks. Once the above symptoms of unknown cause occur, one should go to the hospital for examination and diagnosis immediately to prevent delay. The key to preventing pneumonia in the elderly lies in prevention. First, they should actively participate in physical exercise within their capacity to enhance their physical fitness and improve their disease resistance. Second, it is necessary to have a balanced diet. While supplementing sufficient high-quality protein, vitamins and trace elements, one should also appropriately consume more foods that nourish Yin and moisten the lungs. Third, pay attention to the hygiene of the living room. The living quarters of the elderly should be kept clean frequently. Fourth, one should adhere to the theories of traditional Chinese medicine that "all diseases originate from cold" and "wind is the chief of all diseases", and pay attention to keeping warm and protecting against wind to prevent cold pathogen from invading and causing a cold. Fifth, mental health should be given due attention. Keep a cheerful spirit, an optimistic mood and psychological balance. (According to Xiezhong Health News
