The common cold is caused by a viral infection that affects the upper respiratory system, including the nose and throat. The body’s immune response to the infection often leads to inflammation in the airways, which can result in coughing as a way to clear the airways. After the cold symptoms subside, the airways may still be irritated, causing a lingering cough. In this blog, we’ll explore the typical duration of a cold-related cough and explain when it might be necessary to seek medical care.

What Causes a Lingering Cough After a Cold?

Any cough that lasts after a common cold is known as a post-viral or post-infectious cough and these can be caused by other illnesses apart from colds. In adults, the common causes of the post-viral cough are:

1. Post-Viral Cough Inflammation

This is the most common reason for a cough after a cold. Even after the infection is no longer active, the inflammation in the respiratory system can persist, leading to coughing. This type of cough can last for weeks, even after other cold symptoms have disappeared.

2. Post-Nasal Drip

Another reason why a cough can last after a cold is because of post-nasal drip. This is a condition in which after catching a cold, mucus builds up and drips back into the throat, leading to irritation and a compulsion to cough as a natural body reaction to relieve the system of the mucus. This often occurs when you lay flat on your back during a mucus build-up and unless the mucus build-up is clear or stopped, the cough will continue to linger.

3. Increased Sensitivity of the Airways: The tissues in the airways can remain sensitive and reactive following a cold, which means your body may continue to trigger coughing in response to normal stimuli, like cold air, smoke, or dust.

4. Underlying Conditions, Including Asthma

Asthma is an upper respiratory condition that can cause the airways to become inflamed, swollen, and sensitive. When an individual with asthma gets a cold, the already present inflammation in the airway only serves to agitate the condition further and cause symptoms like a lingering, persistent cough.

How Long Does This Cough Last?

The duration of a cough after a cold can vary from person to person, but generally, a cough can last anywhere from a few days to 3 weeks. Most coughs from a cold tend to last about 1 to 2 weeks, with the worst of it occurring during the first week. If the cough persists for longer than 3 weeks, it could be a sign of another underlying issue, including a sinus infection, bronchitis, or pneumonia. While most coughs after a cold are harmless and will resolve on their own, there are certain signs that you should seek medical attention. This includes coughs lasting longer than 3 weeks, severe coughing fits, discolored mucus, and a high fever.

How To Prevent and Treat a Post-Cold Cough

Post-infectious coughs can take a toll on individuals suffering from it, disrupting their sleep, daily activities, and work. Here’s how to prevent and treat any lingering cough:

Prevention:

• Avoid lying on your back during a serious release of mucus
• Make sure to eat a healthy and nutritious diet, especially one with a lot of fruit for Vitamin C
• Stay hydrated to thin mucus and soothe the throat
• Avoid smoking or inhaling secondhand smoke

Treatment:

• Make use of over-the-counter medications to prevent mucus build-up which can lead to post-nasal drip
• Use decongestants and nasal sprays to reduce inflammation and swelling of the nose
• Humidifiers and steam can be used to provide moisture that can be used to soothe sore throats and nasal passages
