Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease, a common and frequent disease among the elderly in China, which occurs in winter and spring or when the climate changes suddenly, therefore, how to spend the winter has become a concern for elderly COPD patients. 1, keep fresh air indoors, temperature and humidity should be appropriate, avoid triggering factors Quit smoking is the main and simple measures to prevent COPD, reduce the crowded public places, climate change in time to increase and reduce clothing, avoid cold and cold, avoid smoke and dust inhalation, keep the temperature of the room at the appropriate level, do not close the doors and windows to keep warm, should open the windows at the right time to ventilate, but should avoid blowing convective wind. In addition, the dry air in winter can easily trigger COPD, so you can use humidifiers, water sprinklers and other methods to maintain a certain level of humidity in the room. 2, appropriate exercise Usually patients will mistakenly believe that activity can aggravate the symptoms and reduce exercise. In fact, frequent aerobic exercise, such as walking, jogging, playing tai chi and doing breathing exercises, including lip reduction breathing, blowing balloons, blowing candles, can maintain and enhance alveolar elasticity, increase ventilation, improve the oxygen content in the blood and relieve hypoxia. However, because of the dry weather in the early morning, the temperature is low, you can adjust the exercise time to 9 to 10 o’clock in the morning. Pay attention to cold and warmth when you go out. 3, improve cold tolerance and immune function In winter, cold exercise can enhance the patient’s ability to resist the cold, so as to prevent the recurrence of the disease, such as cold water friction on the face and neck can enhance the skin’s adaptability to cold, improve the body’s cold tolerance and reduce the number of winter episodes. This exercise is best to start in the summer, first with a cold towel to rub the head and face, and gradually expand to the limbs. For those with better constitution and strong tolerance, the whole body can be a large area of cold water rubbing bath, adhere to September, October and then return to the face and neck cold water rubbing. The temperature of cold water rubbing in winter is around 15 ℃, 1 to 2 times a day, 10 to 15 minutes each time. Vaccination can help reduce respiratory infections and significantly reduce the possibility of acute attacks and hospitalization; application of immunomodulatory drugs, such as thymidine and panflux, can improve their own resistance; physical exercise can also indirectly improve immune function. In addition, we should also pay attention to the combination of work and rest, to maintain adequate sleep and routine, which can help enhance the ability to resist disease. 4, eat less or do not eat warm food Because of the long-term lack of oxygen in patients with chronic obstructive pulmonary disease, there are varying degrees of malnutrition, so it should be supplemented with a sufficient amount of high-quality protein, vitamins and trace elements food. In the case of normal spleen and stomach function, no obvious anorexia, diarrhea, chest tightness, abdominal distension, you can eat more eggs, duck, chicken, pigeon meat, fish and other flat tonic products, often drink milk, soy milk, but mutton, dog meat and other warm food should be eaten less or not, do not eat high carbohydrate, high sugar content of food. 5.Appropriate treatment The winter weather is dry, the respiratory tract is not wet enough, the sputum is sticky and not easy to cough up, apply expectorant medicine and nebulization treatment, let family members pat the chest and back in the seat or prone position to facilitate sputum discharge. Home oxygen therapy can reduce the number of episodes and improve the quality of life. Continue to maintain medication during the remission period. If coughing, sputum, wheezing or the degree of dyspnea worsens, you should go to the hospital in time for proper treatment. Cordyceps has the function of protecting lung and benefiting kidney, enhancing body immunity, anti-inflammatory and anti-hypoxia, and diastolic bronchial smooth muscle; Astragalus raw vein drink and raw vein capsule have the function of improving immune function, anti-hypoxia and anti-diaphragm fatigue; Yu Ping Feng capsule has the function of enhancing leukocyte and phagocyte, and has the function of restoring those with low immune function. Traditional Chinese medicine requires evidence-based treatment, and herbal tonics or creams can be used for treatment or conditioning according to specific conditions to prevent acute exacerbation. 6.Psychological guidance Treat the disease with a positive attitude, go out for a walk, listen to music, raise flowers and plant plants, etc. to distract attention, reduce loneliness and relieve anxiety and nervous mental conditions.
