As soon as the weather gets cold, I feel tight breathing. What's the matter?

It belongs to airway hyperresponsiveness, which is actually sensitive to cold air, that is to say, this cold air stimulation may lead to certain changes, such as coughing, wheezing in severe cases, and may develop into asthma. Pulmonary function and PEF mutation rate should be checked. If asthma or COPD can be diagnosed, treat it according to the guidelines. If not, pay attention to protecting the respiratory tract and wear a mask in cold weather.
