Chronic bronchitis is a cough with mucus that lasts for at least 3 months in a row 2 years in a row.  Your chest x-ray and spirometry may be normal with chronic bronchitis.  Most instances of chronic bronchitis are due to cigarette smoking.  However people who have not smoked may get bronchitis from repeated exposure to high air pollution or from work exposures, especially when there is a family history of chronic obstructive pulmonary disease (COPD).  This is a combination of chronic bronchitis and emphysema.

Some people do report having more difficulty with their breathing when it is hot and humid.  Many such things, we can't explain.  It might be something else that accompanies the heat and humidity, such as high air pollution.
