periods of poor air quality
If your symptoms consistently improve when you leave a particular environment, environmental exposure may be contributing.
People who work around dust, chemicals, industrial fumes, or other respiratory irritants may need appropriate workplace protection and medical evaluation if symptoms persist.

Chronic Bronchitis Can Cause Long-Term Phlegm If you have been coughing up phlegm regularly for a long time, chronic bronchitis is another possible explanation.
Chronic bronchitis is a type of chronic obstructive pulmonary disease (COPD) characterized by long-term inflammation and mucus production in the airways.
A typical pattern includes:
Persistent cough
Regular mucus production
Shortness of breath
Wheezing
Reduced exercise tolerance
Smoking is a major risk factor, although other long-term exposures can contribute.
A chronic cough with phlegm should not simply be dismissed as “normal aging” or a consequence of smoking.
