What exactly is a dry cough?
Simply put, a dry cough is a cough that does not produce mucus or phlegm . This is also called an "unproductive cough." Normally, our body uses coughing to expel unwanted substances from the lungs and airways, such as viruses, bacteria, and dust.
Think of our respiratory tract as a water pipe. If a piece of debris (phlegm) gets stuck in this pipe, we blow water through it and expel it. That's what a "phlegm cough" is. But in a dry cough, what happens is that there is something inside the pipe that causes the cough, such as irritation, inflammation, or tickling. Even if there is nothing large enough to expel, the inflammation causes the cough to continue.
What are the possible causes of a dry cough?
There can be simple causes of a dry cough, as well as reasons that require a little attention. Let's take a look at the main causes.
| Cause | A simple explanation |
|---|---|
| Allergies | Things like dust, pollen, and animal dander can irritate the respiratory tract and cause coughing. |
| Asthma | A key symptom of asthma is a dry, persistent cough, which can be especially bad at night. |
| GERD (Gastroesophageal Reflux Disease) | This is a severe case of the condition we call "gastritis." Stomach acid backs up into the throat, causing the delicate tissues of the throat to become inflamed and causing coughing. |
| After colds, flu, COVID-19 | When you have a viral infection like this, a dry cough can remain for weeks after the illness has resolved due to inflammation in the respiratory tract. |
| Harmful things in the environment | Inhaling things like cigarette smoke, chemicals, and strong perfumes can irritate the throat and lungs and cause coughing. |
| Some medications (Medication side effects) | Dry cough can occur as a side effect of some medications, especially those used for high blood pressure (e.g. ACE inhibitors). |
| Reasons to be more careful (these are not common, but important to be aware of) | |
| COPD (Chronic Obstructive Pulmonary Disease) | A long-term lung disease that occurs especially in smokers. |
| Other serious conditions | Very rarely, a long-term dry cough can also be a symptom of conditions such as heart failure, lung cancer, or tuberculosis. |
The most important thing is to find out exactly what's causing your cough. The best person to do that is your doctor.
What can you do at home for a bothersome cough?
If the cause of your cough is not serious, you can find relief with these simple things.
- Drink plenty of water and fluids: Drinking warm water and tea can help reduce dryness and irritation in the throat. A cup of warm water with a little honey and lemon is a great solution.
- A teaspoon of honey:Studies have even found that honey has the ability to control coughs. Drinking a teaspoon of honey before bed can reduce sleep disruption caused by coughing. (But don't give honey to babies under one year old).
- Steam Inhalation: Inhaling steam from a bowl of hot water or taking a steamy shower can help moisten the airways and reduce coughing. If you have a humidifier at home, using it is also a good idea.
- Cough drops / Lozenges: When inhaled, these increase saliva production in the mouth and relieve dryness in the throat.
- OTC cough suppressants: There are cough suppressants available at the pharmacy. However, it is best to consult your doctor before using them, as they may not be suitable for some types of cough.
What if small children get a dry cough?
It is not recommended to give children under 4 years of age over -the-counter cough medicines without medical advice. Therefore, if your little one has a cough, the best thing to do is to consult a pediatrician. Using a humidifier at home and filling the bathroom with hot water and steaming it with your child for a while can provide relief.
If you have these symptoms, definitely see a doctor!
Although a dry cough is usually not dangerous, if you have any of the symptoms below along with your cough, don't waste time and see a doctor immediately.
- Coughing up blood
- Difficulty breathing or wheezing
- Extreme fatigue
- Fever and chills
- Sudden, unexplained chest pain
- If you hear a 'wheezing' sound when breathing
Especially if your dry cough lasts for more than three weeks , it is essential to see a doctor to find out what is causing it.
Does coughing hurt your chest?
When you cough hard, you can experience muscle strain in your chest. This is similar to the pain you feel when you lift a heavy object. This pain can usually be relieved with a painkiller like paracetamol.
However, if you experience sudden, severe chest pain , never ignore it. It could be a sign of a heart attack. In such a case, go to the nearest hospital's Emergency Department (ETU) immediately.
