Bronchitis: Signs to watch out for amid winter pollution

Cold weather traps pollutants close to the ground, and breathing this dirty air can irritate the airways. During winter, people with asthma, weak immunity, or frequent respiratory infections are more likely to develop bronchitis. These are the signs you should look out for. (Source: Photo by unsplash)

Chest Tightness: Inflamed airways can cause heaviness or tightness in the chest. Pollution particles make breathing harder, and this pressure like sensation may worsen after outdoor exposure. (Source: Photo by unsplash)

Fatigue: Low-grade fever, tiredness, and body aches often accompany bronchitis as your body tries to fight inflammation. These symptoms may worsen if you’re exposed to cold, polluted air for long periods. (Source: Photo by unsplash)

Persistent Cough: A continuous cough lasting more than a week—especially one that worsens in polluted air is one of the earliest signs of bronchitis. It may start dry but often becomes phlegmy as airway inflammation increases. (Source: Photo by unsplash)

Shortness of Breath on Mild Activity: If you feel breathless even during light tasks like climbing a few steps or walking short distances, this may indicate reduced airflow due to bronchial swelling, especially when pollution levels spike. (Source: Photo by unsplash)

Thick Mucus: Bronchitis often causes mucus that becomes yellow, green, or unusually thick. This change signals inflammation of the bronchial tubes and the body’s attempt to clear irritants caused by polluted winter air. (Source: Photo by unsplash)

Wheezing Sounds: Swollen bronchial passages can create a wheezing sound, particularly on exhaling. Winter smog irritates the airways, making wheezing more common in those developing bronchitis. (Source: Photo by unsplash)
