In the autumn and winter season, the weather turns cooler and the temperature difference between morning and evening is a period of high incidence of respiratory diseases. Coupled with the fact that the new coronary pneumonia has not subsided, friends who already have chronic respiratory diseases are also at high risk of recurrence.
Why are respiratory diseases high in autumn and winter?
(1) The weather turns cooler and some respiratory viruses are rampant. In most parts of the world, this is also the epidemic season for influenza viruses and respiratory syncytial viruses.
(2) The weather is cold in autumn and winter. Due to the consideration of keeping warm, the indoor ventilation is not good, which is easier for pathogens to spread.
(3) The autumn and winter haze is severe, and the harmful particles in the air increase, which can damage the mucosal epithelium of the respiratory tract, reduce the ability of cilia removal, and increase the secretion of mucus, which increases the conditions for pathogen infection.
In particular, some chronic respiratory diseases, such as chronic obstructive pulmonary disease, asthma, etc., often get worse due to changes in weather and the advent of cold air, coughing, increased sputum, and breathing difficulties are more pronounced than before, so treatment has to be strengthened.
For this part of the "dyspnea" friends, although treatment can improve the condition, it cannot be completely cured, and the condition is repeated, so prevention of acute exacerbation is the key.
For effective prevention, pay attention to these details
1. Quit smoking
Smoking is the most important environmental pathogenic factor for chronic respiratory diseases such as chronic bronchitis, chronic obstructive pulmonary disease, and asthma. It can be said that if you don\'t quit smoking, then there is no way to treat these patients.
Quitting smoking is the most critical preventive and therapeutic measure. At the same time, avoid inhaling "second-hand smoke."
2. Keep away from air pollution
Because harmful gases in the atmosphere, such as sulfur dioxide and nitrogen dioxide, can damage our airway mucosa, and many other dust, particulate matter, and smoke are also risk factors for COPD.
3. Enhance physical fitness and prevent upper respiratory tract infection
Upper respiratory tract infections can easily induce acute exacerbations of "chronic obstructive lung and asthma", so patients should pay attention to active vaccination, including pneumococcal vaccine and annual flu vaccine.
4. Appropriate physical activity
Moderate to high levels of physical activity may slow down the decline in lung function in patients with COPD smoking.
