What exactly is a dry cough?
Simply put, a dry cough is a cough that doesn't produce mucus. It's caused by irritation or inflammation in your airways or throat. This is called an 'unproductive cough' because it doesn't remove anything from the body, such as mucus.Coughing is actually a defense mechanism of our body. It is the body's way of trying to expel things like germs (viruses, bacteria), dust, etc. that enter our lungs and respiratory tract.A 'wet cough' usually comes with an infection. The body produces mucus to try to get rid of germs. But a dry cough comes when the airways become swollen and inflamed.
What are the main causes of dry cough?
There is not one single cause of a dry cough, but many factors can contribute to it. While some are normal, others may be a cause for concern. Let's take a look at the main causes.| Cause | A simple explanation |
|---|---|
| Allergies | A dry cough can occur as the body's response to things like dust, pollen, and animal dander. |
| Asthma | A dry cough is a key symptom of asthma. This can be especially bad at night and during exercise. |
| GERD (Gastroesophageal Reflux Disease) | This is when stomach acid comes up into the throat. When this acid reaches the throat, the inflammation it causes can cause a persistent dry cough. |
| Postnasal Drip | When mucus drains from the nose down the throat, it can cause a sore throat and cause coughing. |
| Some medications | Dry cough can occur as a side effect of some medications, especially those used for high blood pressure (ACE inhibitors). |
| Smoking and environmental fumes and dust | Smokers, as well as those who live in environments with smoke, chemicals, and excessive dust, also experience dry coughs due to inflammation of the respiratory tract. |
| After viral infections | Even after an illness like a cold, flu, or COVID-19 has resolved, a bothersome dry cough can linger for weeks. |
Reasons that may be a little more serious
Although usually mild, sometimes a persistent dry cough can be a symptom of a serious underlying condition. For example:- COPD (Chronic Obstructive Pulmonary Disease) - a long-term lung disease
- Heart Failure
- Lung Cancer
- Pneumonia
What are some home remedies for this cough?
In most cases, treating the underlying cause of a dry cough will help the cough improve. However, there are a few things you can do at home to help relieve the discomfort of a cough.- Drink plenty of water and fluids: Drinking hot water, soups, and things like ginger and coriander can help reduce throat dryness and inflammation.
- A teaspoon of honey: Honey is a great remedy for a sore throat. Drinking a teaspoon of honey with a few drops of lime in a cup of hot water can provide great relief. Some studies suggest that honey is just as effective at controlling a cough as over-the-counter cough syrups. (But don't give honey to babies under one year old .)
- Steam Inhalation:If you have a humidifier, use it. It adds moisture to the air and reduces dryness in the throat and nose. If you don't have one, you can also get the same relief by taking a hot shower or by closing the bathroom door and inhaling the steam.
- Cough Drops: Sucking on cough drops that contain ingredients like menthol will increase saliva production and reduce throat irritation.
- Over-the-counter medications: There are cough suppressants available over-the-counter from pharmacies. However , it is always safest and best to ask your doctor what is best for your condition.
