Cough: Causes, Best Syrup and Home Remedies
What is Cough?
A cough is a reflex action that clears your throat and airways of mucus and irritants. It’s a normal, healthy response to something irritating your throat or lungs.
Coughing is good because it helps keep your throat and airways clear. When you have a cold or other respiratory infection, coughing helps to expel the mucus and other secretions from your lungs. This prevents the buildup of mucus, which can lead to further respiratory infections.
Coughing also helps to prevent aspiration, which is when liquids, food, or vomit are brought up from the stomach and then breathed in (inhaled). Aspiration can cause pneumonia, so it’s important to cough up anything that may be in your lungs before it gets a chance to be aspirated.
While coughing is generally a good thing, there are times when it can be problematic. If you’re coughing up blood, this could be a sign of a more serious condition and you should see a doctor right away. Also, if coughing is keeping you from sleeping or interfering with your daily activities, it’s time to see a doctor to find out what’s causing the cough and how to treat it.
What Causes It?
Viruses. Colds and the flu are the most common causes. While annoying, coughs that are “productive” get germy mucus out of your lungs when you’re sick. Most will go away in a few days. After a cold, though, some “dry” cough last weeks. That could be because coughing irritates your lungs, which leads to more coughing, which irritates your lungs, and so on.
Allergies and asthma. If you have them, inhaling a trigger like mold can cause your lungs to overreact. They’re trying to cough out what’s bothering them.
Irritants. Even if you’re not allergic, things like cold air, cigarette smoke, or strong perfumes can set off a hacking spell.
Postnasal drip. When you’re congested, mucus drips down from your nose into your throat and makes you cough. You can get postnasal drip from colds, flu, sinus infections, allergies, and other problems.
Acid reflux. When you have heartburn, stomach acids back up into your throat, especially at night. They can irritate your windpipe, vocal cords, and throat and make you cough.
COPD. This includes one or more of three separate serious conditions: Emphysema, chronic bronchitis, and chronic obstructive asthma. These illnesses weaken the tubes in your airway (bronchial tubes) and the tiny sacs (alveoli) that pass oxygen into your blood and remove carbon dioxide. Cigarette smoking is the most common cause of COPD.
Other causes. Many other problems — lung inflammation, sleep apnea, and drug side effects — can be triggers. Get coughs that won’t go away checked out to make sure you don’t have a separate problem.
