Why is bronchitis worse at night?


Bronchitis is a respiratory condition characterized by inflammation of the bronchial tubes that carry air to the lungs. Symptoms of bronchitis can worsen at night for several reasons:

  1. Postnasal drip: When you lie down, mucus from your sinuses can drip down the back of your throat, which can irritate the bronchial tubes and cause coughing.
  2. Acid reflux: Acid reflux can also worsen at night, and stomach acid that backs up into your throat can irritate your bronchial tubes and trigger coughing.
  3. Changes in temperature and humidity: The air can be cooler and drier at night, which can irritate the lining of your bronchial tubes and make breathing more difficult.
  4. Reduced activity: When you’re lying down, you’re not as active as during the day, and this can lead to mucus buildup in the lungs, making it more difficult to breathe.
  5. Circadian rhythms: Our bodies have natural cycles of hormone release and other physiological processes that can affect inflammation and immune response. Some research suggests that bronchitis symptoms may worsen at night due to changes in these cycles.

It’s essential to see a doctor if you have symptoms of bronchitis, as it can lead to more severe respiratory infections if left untreated. Your doctor can help determine the underlying cause of your symptoms and develop a treatment plan to help manage them.
