First of all, we need to understand why slow obstructive pulmonary disease is prone to recurrence or exacerbation in autumn and winter? First of all, when the weather turns cool, the protection ability of human airway decreases and the ability to remove harmful substances is weakened, especially for patients with underlying diseases such as diabetes and immunosuppressive diseases, who are susceptible to viral and bacterial infections; secondly, the temperature and humidity drop in autumn and winter, and the dry and cold air easily stimulates the respiratory tract, making it narrow and causing various symptoms; furthermore, the dust and other harmful particles in the air increase in autumn and winter, which easily triggers colds and coughs, causing the recurrence or aggravation of LDS. The increase in dust and other harmful particles in the air in autumn and winter can easily trigger colds and coughs, which can cause the recurrence or aggravation of the old chronic lung disease. Although the treatment of “slow lung obstruction” can improve the condition, but can not be completely cured, so prevention is the key. How to prevent the recurrence or aggravation of “slow lung” in autumn and winter: 1. Quit smoking and avoid inhaling harmful particles in the air Smoking, including second-hand smoke, is the most important factor affecting the onset and progression of “slow lung”, so patients suffering from ” Chronic obstructive pulmonary” patients must resolutely quit smoking. On the other hand, there are more hazy days in winter, the harmful particles in the haze, especially PM2, 5 is more harmful to the respiratory tract, so in the hazy weather or poor air quality, try not to go out. Second, the active prevention of colds and other upper respiratory tract diseases colds and other upper respiratory tract diseases can easily induce “slow lung” acute aggravation, so you need to actively prevent all kinds of upper respiratory tract diseases. First of all, we need to pay attention to hand hygiene. We should wash our hands regularly and avoid touching the nasal cavity, mouth and lips without washing our hands; pay attention to keeping warm and adding clothes outside; secondly, exercise moderately, but avoid going out to exercise in the morning; pay attention to keeping warm; pay attention to indoor ventilation, open the windows after waking up in the morning, and the time should not be too long. Finally, keep a certain humidity in the room, such as in the air-conditioned room can use a humidifier. Once the upper respiratory tract diseases such as colds need to promptly seek medical attention to avoid inducing acute aggravation of “slow lung”. Third, pay attention to dietary conditioning “slow lung” patients should be appropriate to increase the high protein diet to enhance physical fitness. In the fall and winter, you should eat some high-calorie meat, such as mutton, and often eat fresh vegetables and fruits in season to replenish vitamin C. Also, eat more foods with high vitamin A content, which is beneficial to repair the respiratory mucosa. In terms of dietary contraindications, it is not recommended to eat cold foods, fried and seafood foods. The inhalation drugs include bronchodilators and inhalation hormones, which can play the role of anti-inflammatory and asthma, and cannot be stopped in autumn and winter. On the other hand, influenza vaccination or pneumonia vaccination can be given in the fall and winter to prevent the occurrence and attack of “chronic obstructive pulmonary disease” caused by respiratory tract infection. Finally, Chinese herbal medicine can be used to prevent the occurrence of the disease according to the patient’s physical condition.
