An occasional cough is a normal response to irritation or infection. It helps clear the airways and usually fades once the underlying cause resolves. When coughing continues well beyond recovery, or seems to worsen without explanation, it may indicate ongoing inflammation in the respiratory system. In many cases, persistent coughing is one of the earliest signs of bronchitis.
Recognizing when a cough deserves closer attention can prevent prolonged discomfort and potential complications.
Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. When these tubes become irritated, they swell and fill with thick mucus, making it harder to breathe and triggering a cough reflex to clear the blockage.
There are two main types of bronchitis:
People with weakened immune systems, asthma, or those recently recovered from a respiratory infection are at a higher risk of developing bronchitis.
In the case of bronchitis, inflammation is the primary culprit. Even after the initial virus that caused your cold has left your system, the bronchial tubes may remain sensitive and swollen. This hypersensitivity means that even a deep breath of cold air or a laugh can trigger a coughing fit.
In most acute cases, the cough can last anywhere from 10 to 20 days. If you find yourself wondering how to tell if it's bronchitis, the duration and the "quality" of the cough are your biggest clues.
Bronchitis presents a specific cluster of symptoms that distinguish it from a standard sore throat or hay fever.
The cough may start out dry, but it often evolves into a mucus-producing cough. This mucus (sputum) can be clear, white, yellowish-gray, or even green. Many patients find the cough is worse in the morning or during the night when lying down.
Because the bronchial tubes are inflamed, you may feel a sense of tightness, soreness, or even a burning sensation in the center of your chest, especially when taking a deep breath or during a coughing spell.
If your airways are narrowed by inflammation and mucus, you might experience shortness of breath during light physical activity. You may also hear a whistling or squeaking sound when you breathe, known as wheezing.
Fighting off inflammation takes a toll on your energy levels. It is common to feel deeply fatigued. While a high fever is rare in acute bronchitis, a low-grade fever or occasional chills may occur as your body fights the infection.
The most common cause of acute bronchitis is a virus, often the same ones that cause the common cold and influenza. Because it is viral, antibiotics (which kill bacteria) are usually not effective.
Other triggers include:
Most people can recover from acute bronchitis at home, but you should seek medical attention if:
The most effective way to prevent bronchitis is to quit smoking and avoid secondhand smoke. Additionally, practicing good hand hygiene during flu season and wearing a mask in dusty or chemical-heavy environments can significantly lower your risk.
A persistent cough is your body’s way of sounding an alarm. While it might just be a lingering cold, it is important to pay attention to the bronchitis warning signs. Taking your symptoms seriously and seeking early evaluation can help you breathe easier and prevent complications like pneumonia.
Don’t ignore the "nagging" cough, listen to what your lungs are trying to tell you.

Prolonged coughing often results from lingering airway inflammation, bronchitis, post-viral sensitivity, or ongoing exposure to respiratory irritants.
A cough lasting several weeks with mucus production, chest discomfort, wheezing, or fatigue commonly points toward bronchitis.
It is typically deep, frequent, and may sound wet or rattling due to mucus in the airways.
Medical care is advised if coughing persists beyond three weeks, worsens, affects breathing, or is accompanied by fever or blood.
Acute bronchitis coughing generally lasts two to three weeks, though airway sensitivity may extend symptoms longer.
