Chronic obstructive pulmonary disease attack in cold weather? How to improve?

In summer, the temperature is high and hot, and people's pores are open, which is easily affected by wind evil. In winter, the weather is cold and dry, and diseases follow. For example, the most common is respiratory infection, including influenza, asthma, chronic bronchitis, chronic obstructive pulmonary disease and so on. Especially the elderly and children, bring trouble to many families.

Why is chronic obstructive pulmonary disease easy to attack when it is cold?

Especially in winter, we all know that it is a cold season, and the temperature of the gas we breathe is lower than other seasons. So when the temperature is low, the inhaled airflow is actually a very low-temperature airflow, and the low-temperature airflow is actually a physical stimulus, which will stimulate the airway.

When stimulated by cold air flow, the airway of normal people will also produce contraction reaction, and the responsiveness of patients with chronic obstructive pulmonary disease will be stronger and more obvious. Because the patient's airway has inflammation and reaction changes, the sensitivity to external stimuli will increase. In this case, the patient's airway is not smooth. At this time, it will contract again, which will obviously aggravate the airway obstruction that is unfavorable to patients with chronic obstructive pulmonary disease.

In fact, because the cold in winter aggravated the obstruction, patients may have many secondary problems. In this cold season, respiratory tract infection is more likely to occur, because the local defense and immune function of the airway will decline, which will cause respiratory tract infection in cold weather, which is also the reason why patients are prone to acute exacerbation in winter.

Prevention of Chronic Obstructive Pulmonary Disease in Winter

1, cold and warm

Pay more attention to the weather, increase clothes in time, and avoid colds caused by ignoring weather changes. When going out, prepare clothes, scarves, hats and masks suitable for going out to avoid catching a cold.

In winter, we habitually close the doors and windows for a long time, and the air circulation is also problematic. Bacteria and viruses accumulate indoors, so we need regular ventilation.

Try to avoid eating cold food. In addition, when the weather is dry, drink warm water to ensure the amount of water.

2. Early treatment

If there are symptoms of respiratory tract infection or seizure, it is very important to pay attention to it and treat it in time to avoid recurrence. In addition, patients should pay attention to regular inspection.

Stay away from pathogenic factors

Quit smoking and reduce exposure to risk factors (secondhand smoke, harmful gas dust, air pollution, etc.). ).), and get influenza vaccine and streptococcus pneumoniae vaccine.

Strengthen exercise

Pay attention to daily exercise, choose the appropriate time and place to exercise according to the characteristics of winter weather, improve the body's immunity and enhance its adaptability to the external environment. Maintain regular work and rest habits, ensure adequate sleep and avoid excessive fatigue.

The cold climate is also a factor affecting the incidence of chronic obstructive pulmonary disease. In cold winter, or living in a cold climate area, we should consciously keep warm and take protective measures to reduce the frequency of chronic obstructive pulmonary disease and avoid the aggravation of the disease and the damage of lung function.
