Do you wake up at night because of a severe cough that won’t stop? Or are you suffering from a persistent dry cough for weeks without finding a solution? A cough is not a disease in itself; rather, it is a signal from your body that something is irritating your respiratory system and needs attention.
Cough or coughing affects almost everyone at some point, especially with seasonal changes and the spread of viral infections. But the problem begins when it turns into a persistent cough that stays with you for weeks and affects your sleep, energy, and daily life.
In this comprehensive guide, we review everything you need to know about the causes of cough in its various types, the best ways to treat cough, whether at home or with medical intervention, and the crucial role your immune system plays in how quickly you recover.
What is a cough and why does it happen?
A cough is a natural reflex action that the body uses to clear the airways of mucus, foreign objects, and irritants such as dust and smoke. This reflex begins when nerve receptors in the throat, trachea, and lungs become irritated, sending signals to the brain, which then instructs the chest and abdominal muscles to contract forcefully to expel air — and this is what we hear and feel as a cough.
In most cases, a cough is a temporary symptom that resolves within one to two weeks. But when it lasts longer, it may indicate a health problem that requires diagnosis and treatment, and here understanding the cause of the cough becomes the first key to proper treatment.
It is important to distinguish between the main types of cough: a dry cough that is not accompanied by mucus and is often caused by throat irritation or allergies, and a wet cough that is accompanied by mucus or phlegm and is usually associated with a respiratory infection.
Causes of cough — why doesn’t it stop?
The causes of cough vary widely, ranging from simple and temporary to those requiring medical attention. Understanding the cause is the first step toward effective treatment.
Sudden cough causes
When a cough starts suddenly without warning, the most common causes include: viral infections such as the common cold, influenza, and COVID-19 that cause inflammation in the upper respiratory tract; inhalation of irritants such as dust, cigarette smoke, strong perfumes, or chemicals; exposure to allergens such as pollen, animal dander, or mold; as well as a foreign object entering the airways, especially in children.
Chronic and persistent cough causes
When a cough lasts more than three weeks and turns into a bothersome persistent cough, the most common causes include: postnasal drip, where mucus slides from the sinuses to the back of the throat causing continuous irritation and coughing especially during sleep; asthma, which is characterized by a dry cough accompanied by shortness of breath and wheezing; gastroesophageal reflux disease (GERD), where stomach acid rises to the esophagus and throat causing irritation and chronic cough especially after eating or when lying down; and certain blood pressure medications such as ACE inhibitors that cause a persistent dry cough as a side effect.
Causes of dry cough specifically
Dry cough has its own causes that distinguish it from a wet cough. The most common causes include: seasonal or chronic allergies to dust or pollen; throat irritation caused by dry air, especially with the use of air conditioning in Saudi Arabia; exposure to cigarette smoke directly or secondhand; and dry cough after recovery from COVID-19, where airway irritation may persist for weeks after the infection resolves.
Treatment of dry cough — medical and home methods
Treatment of dry cough depends on identifying the cause first and then choosing the appropriate treatment. The following are the main methods:
Home treatment — effective natural methods
Before turning to medication, there are several natural ways to treat cough that can significantly relieve symptoms. Among the most important is consuming natural honey, which studies have proven effective in soothing cough — you can dissolve a spoon of honey in a cup of warm water with lemon juice and drink it several times a day. Gargling with warm salt water also helps soothe throat inflammation and reduce irritation. Another effective method is inhaling steam, which moisturizes the airways and reduces dryness, in addition to drinking plenty of warm fluids such as herbal teas, ginger, thyme, and licorice that help soothe the throat. Do not forget to elevate your head during sleep to reduce postnasal drip and nighttime coughing.
Dry cough treatment for adults — medical options
When home remedies are not enough, medical treatment becomes necessary. The most common options include: cough suppressants such as dextromethorphan, which calm the cough center in the brain; antihistamines for allergies; bronchodilators for asthma patients; and proton pump inhibitors if the cause is acid reflux. Always consult a doctor before taking any medication to determine the best treatment for your condition.
Severe cough treatment — what treats a strong cough?
A strong cough that does not respond to usual treatments requires a different approach. When severe cough is accompanied by shortness of breath or chest pain, fast treatment requires immediate medical consultation to determine the cause — whether it is pneumonia, severe asthma, or a bacterial infection that requires antibiotics.
While waiting for a doctor’s appointment, you can relieve the cough by drinking warm fluids, sitting upright, and avoiding irritants such as smoke and perfumes.
Nighttime cough — why it worsens and how to get rid of it
One of the most common complaints is a persistent cough at night that prevents restful sleep. The cause is often a combination of factors: lying down allows mucus to collect in the back of the throat, increasing postnasal drip; acid reflux worsens when lying down; and dry air in air-conditioned rooms irritates the airways.
To treat nighttime cough, try elevating your head with an extra pillow, using a humidifier in the bedroom, avoiding eating at least two hours before sleep, and taking a spoon of warm honey before bed.
Cough with Phlegmatic — treatment differs
When a cough is accompanied by phlegm, the treatment differs completely from a dry cough. In this case, the goal is not to stop the cough but to help expel the mucus. Therefore, expectorant medications are used to loosen mucus and make it easier to clear. Drinking plenty of water helps thin the mucus, and steam inhalation is very effective.
Cough and chest pain — when to worry
If a cough is accompanied by chest pain, it may indicate inflammation in the airways or lungs, or simply muscle strain from frequent coughing. In mild cases, the pain results from muscle strain and improves as the cough improves. However, if the pain is severe or accompanied by shortness of breath or high fever, medical attention is necessary.
Coughing blood — a sign that requires immediate medical attention
Coughing up blood — even in small amounts — requires urgent medical evaluation. It may be due to severe throat irritation or a nosebleed, but it can also indicate more serious conditions such as pneumonia, tuberculosis, or tumors. Do not delay medical consultation in this case.
Cough and allergies — a close relationship
Allergies are among the most common causes of dry cough in Saudi Arabia due to dust, sand, and climate changes. Treatment involves identifying and avoiding triggers, then using antihistamines and nasal steroid sprays when needed.
In cases where cough, phlegm, and allergies occur together, a doctor may prescribe a combination of antihistamines and expectorants to control symptoms effectively.
When is a cough dangerous?
Many people ask when a cough becomes serious. You should see a doctor immediately in the following cases: if the cough lasts more than three weeks without improvement; if there is blood in the cough; severe shortness of breath or wheezing; unexplained weight loss; severe chest pain; persistent high fever; or difficulty swallowing or speaking.
A normal cough usually lasts one to two weeks in cases of colds and flu. Any cough lasting longer than three weeks is considered chronic and requires medical evaluation.
Things that relieve cough in children — important tips for mothers

Treating cough in children requires special care because some medications are not suitable for them. Helpful methods include: honey for children over one year only; humidifying the room air; giving warm fluids; using saline nasal drops; and elevating the child’s head during sleep.
For the best cough treatment for children, always consult a pediatrician before giving any medication, especially for children under four years old.
The role of strong immunity in preventing and recovering from cough
The reason some people recover quickly from colds while others suffer from a persistent cough for weeks is the strength of their immune system. A strong immune system is the first line of defense against disease.
Key nutrients include vitamin C, vitamin D, and zinc, which support immune function and help fight infections.
Many people in Saudi Arabia suffer from deficiencies in these nutrients, making them more vulnerable to infections and persistent cough.
evercare provides IV vitamin therapy to boost immunity, including vitamin C IV sessions with over 99% absorption compared to 8% orally, as well as comprehensive immune boost drips containing more than 14 essential nutrients.
