A lingering cough, often referred to as a chronic cough or post-infectious cough, is a symptom that can persist long after an upper respiratory infection has resolved. This condition can be particularly distressing, as it disrupts daily activities and can lead to sleep disturbances. A lingering cough is characterized by its duration, typically lasting more than eight weeks, and may be accompanied by throat irritation, wheezing, or shortness of breath. Understanding the underlying causes and exploring natural remedies can provide relief and support recovery.
Common Causes of Lingering Cough from Infection
A lingering cough can be a frustrating and uncomfortable symptom, often persisting long after an infection has resolved. Various factors can contribute to this condition, including:
- Post-viral Cough: After a respiratory infection, such as the common cold or flu, inflammation in the airways may continue, causing a persistent cough.
- Allergies: Allergens like pollen, dust, or pet dander can irritate the throat and lungs, leading to a chronic cough.
- Asthma: This condition can be triggered by infections, resulting in a lasting cough as the airways remain sensitive.
- Gastroesophageal Reflux Disease (GERD): Acid reflux can irritate the throat and cause a cough that lingers.
- Chronic Bronchitis: A history of smoking or exposure to irritants can lead to chronic bronchitis, where a cough persists for extended periods.
Understanding the underlying cause of a lingering cough is crucial in finding effective remedies.
