Executive Summary
Chronic cough stands as one of the most common reasons patients seek medical attention, affecting approximately 10% of the adult population worldwide and representing a significant source of morbidity, healthcare utilization, and diminished quality of life. In Dubai’s unique healthcare landscape, with its diverse population, environmental challenges including dust and sandstorms, and the convergence of various medical traditions, understanding chronic cough becomes particularly relevant for residents seeking comprehensive care. This guide provides an in-depth exploration of chronic cough, from its underlying mechanisms to the full spectrum of treatment approaches available at Healers Clinic Dubai.
Chronic cough is defined as a cough lasting longer than 8 weeks in adults or 4 weeks in children. While often perceived as a simple symptom, chronic cough frequently represents a complex diagnostic challenge with multiple potential underlying causes that may coexist and interact. The three most common causes of chronic cough in adults who do not smoke and are not taking angiotensin-converting enzyme (ACE) inhibitors are upper airway cough syndrome (formerly called post-nasal drip syndrome), asthma and eosinophilic bronchitis, and gastroesophageal reflux disease. However, these conditions may be difficult to distinguish clinically, and some patients have multiple contributing factors.
At Healers Clinic Dubai, we recognize that effective chronic cough management requires a comprehensive, patient-centered approach that addresses not only the underlying causes but also the hypersensitivity of the cough reflex that often perpetuates symptoms. Our integrative medicine philosophy combines evidence-based conventional treatments with complementary therapies including nutritional support, stress management, and traditional healing modalities to address the whole person and achieve optimal outcomes.
This comprehensive guide will walk you through everything you need to know about chronic cough, empowering you to understand your symptoms, work effectively with healthcare providers, and take an active role in your journey toward resolution.

Understanding Chronic Cough - Comprehensive Overview
What Is Chronic Cough?
Chronic cough is defined as a cough that persists for more than 8 weeks in adults. It is a symptom, not a diagnosis, and represents the manifestation of underlying disease processes affecting the respiratory system or other organs. The cough reflex is a protective mechanism designed to clear the airways of irritants and secretions, but in chronic cough, this reflex becomes hypersensitive and may be triggered by stimuli that would not normally provoke coughing.
The pathophysiology of chronic cough involves both peripheral and central mechanisms. At the periphery, inflammation or irritation of the airways activates cough receptors, which send signals via the vagus nerve to the cough center in the medulla oblongata. The cough center then coordinates the complex motor response of coughing. In chronic cough, this reflex arc becomes sensitized, with lower thresholds for activation and amplified responses.
Cough receptors are found throughout the respiratory tract, from the pharynx to the bronchi, as well as in the ear canal, stomach, and other sites. These receptors respond to mechanical and chemical stimuli. In chronic cough, increased sensitivity of these receptors (peripheral sensitization) and the central nervous system processing (central sensitization) leads to excessive and often ineffective coughing.
The impact of chronic cough on quality of life can be profound. Patients may experience fatigue from disrupted sleep, urinary incontinence (particularly in women), syncope (fainting) from severe coughing spells, muscle pain from repetitive coughing, embarrassment and social isolation, anxiety and depression, and reduced work productivity. The burden of chronic cough is comparable to or exceeds that of other chronic conditions such as chronic obstructive pulmonary disease and heart failure.
The Epidemiology of Chronic Cough
Chronic cough is a common problem worldwide, with prevalence estimates ranging from 3% to 12% depending on the population studied and definition used. It is one of the most common reasons for primary care visits and accounts for a significant proportion of referrals to pulmonology and allergy specialists.
Demographically, chronic cough is more common in women than in men, with some studies suggesting a 2:1 female predominance. This difference may relate to hormonal factors, differences in cough reflex sensitivity, or differences in reporting behavior. Chronic cough can occur at any age but is more common in older adults, who may have accumulated risk factors and reduced physiological reserves.
Occupational factors influence chronic cough prevalence. Workers exposed to dusts, chemicals, fumes, or other respiratory irritants may develop chronic cough as a manifestation of occupational lung disease or as a result of airway hyperresponsiveness.
Geographic and environmental factors also play a role. In regions with high levels of air pollution or dust exposure, chronic cough may be more prevalent. In Dubai, environmental factors including sandstorms, air conditioning use, and indoor air quality may contribute to respiratory symptoms including chronic cough.
The Anatomy and Physiology of Cough
Understanding cough requires knowledge of the anatomical structures and physiological processes involved in this reflex.
The cough reflex is initiated by activation of cough receptors (irritant receptors) located in the larynx, trachea, and bronchi, as well as in the pharynx, ear canal, stomach, and diaphragm. These receptors respond to mechanical irritation (touch, pressure, stretch) and chemical irritation (inflammatory mediators, irritants).
When activated, cough receptors send afferent signals via the vagus nerve to the cough center in the medulla oblongata. The cough center processes this information and coordinates the cough response through efferent pathways to the respiratory muscles.
The cough reflex consists of several phases: inspiration (drawing air into the lungs), glottic closure (closing the vocal cords), forceful expiration against the closed glottis (building intrathoracic pressure), and glottic opening and rapid expiration (expelling air and any material in the airways).
In chronic cough, this reflex arc becomes sensitized. Peripheral sensitization involves increased sensitivity of cough receptors, so that stimuli that would not normally trigger coughing do so. Central sensitization involves changes in the central nervous system processing of cough signals, amplifying the response. This hypersensitivity explains why treatments aimed solely at addressing the underlying cause may be insufficient, and why therapies targeting the cough reflex itself are often necessary.
The Causes of Chronic Cough
Chronic cough has numerous potential causes, which can be classified in various ways. The most useful clinical approach considers the anatomic distribution of the causes.
Upper airway causes include upper airway cough syndrome (UACS), previously termed post-nasal drip syndrome. This is caused by mucus draining down the back of the throat, stimulating cough receptors. Causes include allergic rhinitis, non-allergic rhinitis, chronic sinusitis, and environmental irritants.
Lower airway causes include asthma, eosinophilic bronchitis, non-asthmatic eosinophilic bronchitis, chronic bronchitis, bronchiectasis, and bronchogenic carcinoma. Asthma-related cough may be the sole manifestation (cough-variant asthma) or occur with other asthma symptoms.
Gastroesophageal causes include gastroesophageal reflux disease (GERD), laryngopharyngeal reflux, and esophageal motility disorders. Acid or non-acid refluxate can stimulate cough receptors in the esophagus or reflux into the airway.
Cardiac causes include left ventricular dysfunction and congestive heart failure. “Cardiac asthma” refers to wheezing and cough resulting from pulmonary congestion.
Medication causes include ACE inhibitors, which cause cough in 5-20% of users, typically beginning within weeks of starting the medication but sometimes delayed for months.
Other causes include chronic respiratory infections (including tuberculosis, whooping cough), interstitial lung diseases, sarcoidosis, psychological factors (habit cough, psychogenic cough), and idiopathic cough (when no cause is identified despite thorough evaluation).
In clinical practice, the majority of chronic cough cases fall into three categories: upper airway cough syndrome, asthma/eosinophilic bronchitis, and gastroesophageal reflux disease. These three conditions are sometimes called the “triad” of chronic cough causes and may coexist in the same patient.

The Science Behind Chronic Cough
Neurophysiology of the Cough Reflex
The cough reflex is a complex protective mechanism involving sensory receptors, neural pathways, and motor responses. Understanding the neurophysiology of cough provides insight into why chronic cough develops and how it can be treated.
Sensory nerves innervating the airways include myelinated A-delta fibers (rapidly adapting receptors) and unmyelinated C fibers (slowly adapting receptors). A-delta fibers respond to mechanical stimuli and are involved in the cough reflex triggered by physical irritants. C fibers respond to chemical stimuli including capsaicin, acid, and inflammatory mediators.
The vagus nerve carries sensory information from the airways to the nucleus tractus solitarius in the medulla, which serves as the cough center. The cough center integrates this information and coordinates the motor response through various brainstem nuclei and higher cortical centers.
In chronic cough, both peripheral and central sensitization occur. Peripheral sensitization involves upregulation of cough receptors and increased sensitivity to stimuli. Central sensitization involves neuroplastic changes in the cough center that amplify the cough response. These changes are similar to those seen in other chronic pain conditions, leading some researchers to view chronic cough as a “neuropathic cough syndrome.”
The concept of cough hypersensitivity syndrome has been proposed to describe patients with chronic cough characterized by heightened cough reflex sensitivity. These patients may cough in response to triggers that would not normally provoke coughing, such as talking, laughing, exposure to cold air, or certain odors. This hypersensitivity can persist even after the initial trigger has resolved.
Inflammation and Cough
Airway inflammation plays a key role in many causes of chronic cough. The type and location of inflammation can provide clues to the underlying cause.
Eosinophilic inflammation is characteristic of asthma and allergic conditions. Eosinophils release major basic protein and other mediators that can directly activate cough receptors. Sputum eosinophilia and elevated fractional exhaled nitric oxide (FeNO) are markers of eosinophilic airway inflammation.
Neutrophilic inflammation is seen in some cases of chronic bronchitis, bronchiectasis, and respiratory infections. This type of inflammation may be less responsive to anti-inflammatory treatments.
Lymphocytic inflammation is seen in conditions such as sarcoidosis and some infections. The pattern of inflammation on biopsy can help narrow the differential diagnosis.
The relationship between inflammation and cough is complex. Not all patients with airway inflammation cough, and some patients with chronic cough have no evidence of inflammation on standard testing. This suggests that factors beyond inflammation, including neural hypersensitivity, are important in generating the cough symptom.
The Role of the Upper Airway
The upper airway, including the nose, sinuses, and pharynx, plays a crucial role in chronic cough. The concept of the unified airway recognizes that the upper and lower airways are anatomically and physiologically continuous, with shared mucosa and neural innervation.
Upper airway cough syndrome (UACS) is the most common cause of chronic cough in many clinical series. It is caused by mucus dripping down the posterior pharyngeal wall (post-nasal drip), which activates cough receptors in the pharynx and larynx. Even small amounts of mucus that would not be clinically obvious can trigger cough in sensitized individuals.
The relationship between upper and lower airway disease is bidirectional. Allergic rhinitis and asthma frequently coexist, with each condition potentially exacerbating the other. This “unified airway disease” concept has implications for treatment, as management of upper airway disease may improve lower airway symptoms and vice versa.
Chronic sinusitis, with or without nasal polyps, is an important cause of UACS. Sinus inflammation leads to increased mucus production and post-nasal drip. The association between chronic sinusitis, asthma, and aspirin-exacerbated respiratory disease (AERD) is well recognized.
The Role of Gastroesophageal Reflux
Gastroesophageal reflux disease (GERD) is one of the three major causes of chronic cough. The mechanisms by which reflux causes cough are multiple and may operate simultaneously.
The vagally-mediated esophagobronchial reflex involves activation of esophageal sensory receptors by refluxate, with vagal afferents triggering cough through a reflex arc. This reflex can be activated by both acid and non-acid reflux.
Microaspiration involves small amounts of refluxate entering the airway, directly stimulating cough receptors. This is more likely to occur during sleep or when lying down.
Laryngopharyngeal reflux (LPR) involves refluxate reaching the larynx and pharynx, which are particularly sensitive to acid and pepsin. LPR may occur without typical GERD symptoms (heartburn, regurgitation), a condition sometimes called “silent reflux.”
The relationship between GERD and cough can be complex, as coughing itself can promote reflux by increasing intra-abdominal pressure. This creates a vicious cycle where cough and reflux perpetuate each other.

Common Causes and Risk Factors
Upper Airway Cough Syndrome
Upper airway cough syndrome (UACS), also known as post-nasal drip syndrome, is the most common cause of chronic cough in adults who do not smoke and are not taking ACE inhibitors. It results from conditions that cause excess mucus production or abnormal mucus clearance in the upper airway.
Allergic rhinitis is a major cause of UACS. In allergic individuals, exposure to allergens (pollen, dust mites, pet dander, mold) triggers IgE-mediated inflammation of the nasal mucosa, leading to increased mucus production and post-nasal drip. The cough of allergic rhinitis may be seasonal or perennial depending on the allergen exposure.
Non-allergic rhinitis (vasomotor rhinitis) causes similar symptoms without evidence of allergic sensitization. Triggers include temperature changes, strong odors, humidity changes, and environmental irritants. This condition is common in Dubai’s climate with extensive air conditioning use.
Chronic sinusitis, with or without nasal polyps, causes inflammation of the sinuses and increased mucus production. Symptoms may include facial pressure or pain, purulent nasal discharge, and reduced sense of smell. In Dubai, indoor air quality issues from air conditioning systems may contribute to sinus problems.
Environmental irritants including dust, smoke, strong odors, and chemicals can cause rhinitis-like symptoms and UACS. Occupational exposures may be particularly relevant.
Asthma and Eosinophilic Bronchitis
Asthma is a common cause of chronic cough and may present as cough-variant asthma, where cough is the predominant or sole symptom. In cough-variant asthma, patients have airway inflammation and hyperresponsiveness but do not have wheezing or dyspnea at presentation.
Eosinophilic bronchitis is a condition characterized by eosinophilic airway inflammation and cough, but without the airflow obstruction and bronchial hyperresponsiveness that define asthma. It responds to inhaled corticosteroids similarly to asthma.
The diagnosis of asthma or eosinophilic bronchitis as a cause of chronic cough requires demonstration of eosinophilic inflammation through sputum analysis, elevated FeNO, or bronchial challenge testing. Response to inhaled corticosteroids supports the diagnosis.
Atopic status (evidence of allergic sensitization) increases the likelihood that asthma or eosinophilic bronchitis is the cause of chronic cough. However, non-atopic asthma and eosinophilic bronchitis also occur.
Gastroesophageal Reflux Disease
Gastroesophageal reflux disease (GERD) is a common cause of chronic cough, accounting for up to 40% of cases in some series. The diagnosis can be challenging because many patients do not have typical reflux symptoms.
The mechanisms of reflux-related cough include the esophagobronchial reflex, microaspiration, and laryngeal irritation as discussed earlier. Acid suppression therapy is the mainstay of treatment, though the response may be incomplete.
Laryngopharyngeal reflux (LPR) involves refluxate reaching the larynx and pharynx. Symptoms may include throat clearing, hoarseness, globus sensation (feeling of a lump in the throat), and chronic cough. LPR may occur with normal esophageal pH studies.
Risk factors for reflux-related cough include obesity, hiatal hernia, pregnancy, delayed gastric emptying, and certain medications. Dietary modifications including avoidance of caffeine, alcohol, chocolate, mint, and fatty foods may help.
Other Important Causes
ACE Inhibitors are a common and often overlooked cause of chronic cough. The cough typically begins within weeks of starting the medication but may be delayed for months. It resolves within weeks to months of discontinuing the ACE inhibitor, though in some cases cough may persist for a year or more. Switching to an angiotensin receptor blocker (ARB) is usually recommended, as ARBs have a much lower incidence of cough.
Chronic Bronchitis is defined by cough with sputum production for at least three months in two consecutive years. It is almost always caused by cigarette smoking and is a component of COPD. Smoking cessation is the most important intervention.
Bronchiectasis is permanent dilation of the bronchi, often resulting from prior infections or other insults. It causes chronic cough with copious sputum production, recurrent infections, and may be associated with underlying immune deficiencies or other conditions.
Interstitial Lung Diseases are a group of disorders causing inflammation and scarring of the lung interstitium. They typically cause dry cough and progressive dyspnea.
Cardiac Causes including left ventricular dysfunction and congestive heart failure can cause chronic cough, often worse when lying flat (orthopnea) or waking the patient from sleep (paroxysmal nocturnal dyspnea).
Psychogenic Cough (habit cough) is a diagnosis of exclusion. It is more common in children but can occur in adults. The cough is often “honking” or barking in quality and disappears during sleep.

Diagnosis and Assessment Methods
Clinical Evaluation
The evaluation of chronic cough begins with a thorough history and physical examination. This initial assessment can often narrow the differential diagnosis and guide further testing.
The history should characterize the cough in detail: duration, timing (morning, nighttime, continuous), productivity (dry vs. productive), triggers (cold air, exercise, talking, eating, lying down), and associated symptoms (sputum characteristics, heartburn, post-nasal drip, wheezing, dyspnea, weight loss, fever).
Past medical history may reveal conditions associated with chronic cough: asthma, allergies, sinusitis, GERD, heart disease, previous respiratory infections. Medication history is essential to identify ACE inhibitor use.
Social history should include smoking history (current, former, pack-years), occupational exposures, and home environment (mold, dust, pets). Travel history may be relevant for infections.
Physical examination should include examination of the ears, nose, and throat (looking for evidence of post-nasal drip, nasal polyps, or other abnormalities), neck (lymphadenopathy, thyroid enlargement), lungs (wheezes, crackles, signs of consolidation or hyperinflation), and heart (signs of heart failure).
Diagnostic Testing
Based on the history and physical examination, targeted testing can be performed to identify the cause of chronic cough.
Chest X-ray is indicated in most patients with chronic cough to evaluate for structural lung disease, infection, malignancy, or heart failure. Most guidelines recommend chest X-ray as initial testing.
Spirometry with bronchodilator response can identify obstructive lung disease (asthma, COPD) and assess reversibility. Normal spirometry does not exclude asthma, as normal results may occur between episodes.
Peak expiratory flow monitoring may demonstrate variability suggestive of asthma, particularly if performed over several weeks.
FeNO testing (fractional exhaled nitric oxide) measures eosinophilic airway inflammation and may support a diagnosis of eosinophilic asthma.
Sputum analysis can identify eosinophils (suggesting eosinophilic inflammation) or neutrophils (suggesting chronic infection or bronchiectasis).
Allergy testing (skin prick testing or serum-specific IgE) can identify allergic sensitization, which may support a diagnosis of allergic rhinitis or asthma as the cause of cough.
Sinus imaging (CT scan) is indicated if chronic sinusitis is suspected based on symptoms or physical findings.
Esophageal testing may include upper endoscopy, pH monitoring, or impedance testing if GERD is suspected but not confirmed by history.
Anatomic Diagnostic Protocol
Many experts recommend an anatomic diagnostic approach to chronic cough, systematically evaluating for and treating each of the major causes.
This approach typically involves: chest X-ray and spirometry to exclude major pulmonary disease; trial of treatment for UACS (with nasal corticosteroids, antihistamines, or other agents); trial of treatment for asthma (inhaled corticosteroids); and trial of treatment for GERD (acid suppression with high-dose proton pump inhibitor).
A positive response to empiric treatment supports the diagnosis and allows targeted therapy. A negative response may prompt further investigation or evaluation for alternative causes.

Conventional Treatment Approaches
Treating Upper Airway Cough Syndrome
Treatment of UACS depends on the underlying cause.
For allergic rhinitis, first-line treatment includes intranasal corticosteroids (fluticasone, mometasone, budesonide), which reduce nasal inflammation and mucus production. Antihistamines (oral or intranasal) may be added for symptomatic relief. Allergen avoidance is important when feasible.
For non-allergic rhinitis, intranasal corticosteroids may still be effective. Intranasal antihistamines (azelastine) and anticholinergic sprays (ipratropium) can reduce rhinorrhea. Saline nasal irrigation can help with mucus clearance.
For chronic sinusitis, medical management includes intranasal corticosteroids, saline irrigation, and antibiotics for acute exacerbations. Endoscopic sinus surgery may be indicated for patients who fail medical management.
Environmental modifications including air filtration, humidity control, and avoidance of irritants can help reduce upper airway symptoms.
Treating Asthma and Eosinophilic Bronchitis
Inhaled corticosteroids are the cornerstone of treatment for eosinophilic airway inflammation causing chronic cough. For cough-variant asthma, low to moderate doses of inhaled corticosteroids are typically effective. Response may take several weeks, and treatment is usually continued for several months before tapering.
Combination inhaled corticosteroid/long-acting beta-agonist preparations may be used for patients not controlled on inhaled corticosteroids alone. Leukotriene receptor antagonists (montelukast) may be considered as add-on therapy or for patients who cannot use inhaled corticosteroids.
For eosinophilic bronchitis, the treatment is similar to asthma, with inhaled corticosteroids as first-line therapy. Unlike asthma, bronchodilators are not effective as monotherapy.
Treating Gastroesophageal Reflux
Treatment of reflux-related cough involves lifestyle modifications, dietary changes, and medication.
Lifestyle modifications include weight loss (for overweight patients), elevating the head of the bed, avoiding eating within 2-3 hours of bedtime, and avoiding tight clothing around the waist.
Dietary modifications include reducing intake of caffeine, alcohol, chocolate, mint, fatty foods, and acidic foods. Smaller, more frequent meals may help.
Acid suppression with proton pump inhibitors (omeprazole, esomeprazole, pantoprazole) is first-line medical therapy. Doses are typically higher than those used for typical GERD symptoms, and treatment duration may be 8-12 weeks or longer. H2 blockers (famotidine, ranitidine) may be used as add-on therapy or for maintenance.
Prokinetic agents that improve gastric emptying (metoclopramide, domperidone) may be considered in patients with delayed gastric emptying, though evidence for efficacy in cough is limited.
Addressing Cough Itself
When the underlying causes have been addressed but cough persists, treatments aimed at reducing cough reflex sensitivity may be necessary.
Speech pathology intervention with cough suppression techniques can be effective for refractory cough. This includes education about cough physiology, techniques to suppress the urge to cough, and voice therapy.
Gabapentin and pregabalin, medications that act on calcium channels in the nervous system, have shown efficacy in reducing chronic cough, likely through central mechanisms. Low doses are typically started and titrated based on response and side effects.
Low-dose morphine has been used for refractory chronic cough, though concerns about dependence and side effects limit its use.
Novel therapies under investigation include voltage-gated sodium channel blockers and other neuromodulators targeting the cough reflex.

Integrative and Alternative Medicine Approaches
Ayurveda and Chronic Cough
Ayurveda offers a holistic approach to chronic cough that addresses the underlying doshic imbalances and supports the body’s healing mechanisms. According to Ayurvedic principles, chronic cough involves imbalances in Vata and Kapha doshas.
Dietary modifications emphasize warm, cooked foods that are easy to digest while avoiding cold, heavy, and mucus-forming foods. Spices such as ginger, black pepper, turmeric, and cinnamon are recommended for their warming and expectorant properties. Honey in warm water can help soothe irritated airways.
Herbal remedies used in Ayurveda for chronic cough include Tulsi (Holy Basil) for its expectorant and immune-modulating properties, Licorice root (Yashtimadhu) for soothing irritated respiratory tissues, Pippali (Long Pepper) for respiratory support, and Turmeric (Haridra) for its anti-inflammatory effects.
Panchakarma therapies, including Vamana (therapeutic emesis) and Virechana (therapeutic purgation), may be beneficial for Kapha-related respiratory conditions when performed by qualified practitioners.
Nasya therapy, involving administration of medicated oils through the nasal passages, is traditionally used for chronic respiratory conditions and may help reduce post-nasal drip and cough.
Traditional Chinese Medicine and Acupuncture
Traditional Chinese Medicine views chronic cough as resulting from deficiency of Lung and Kidney Qi, invasion of external pathogens, or phlegm-heat accumulation. Treatment aims to strengthen the Lung and Kidney, resolve phlegm, and clear heat.
Acupuncture has shown promise in the treatment of chronic cough. Studies suggest that acupuncture may modulate the cough reflex through neuroendocrine mechanisms and reduce cough reflex sensitivity. Points commonly used include those on the lung meridian (Feishu, Lieque), throat region (Renying, Lianquan), and other points based on pattern differentiation.
Herbal formulas used in TCM for chronic cough are selected based on the pattern presentation. Formulas may include ingredients to tonify Qi, nourish Yin, resolve phlem, or clear heat.
Cupping and moxibustion may be used as adjunctive therapies for chronic cough in some traditions.
Nutritional Support
Nutritional factors can influence cough through effects on inflammation, mucus production, and immune function.
Anti-inflammatory diets emphasizing omega-3 fatty acids, fruits, vegetables, and whole grains may support respiratory health. Reducing intake of processed foods, sugar, and saturated fats may decrease inflammatory burden.
Adequate hydration helps thin secretions and may reduce cough frequency. Warm liquids can be particularly soothing for irritated airways.
Vitamin D deficiency has been associated with chronic cough in some studies. Testing for and correcting deficiency may be beneficial in deficient individuals.
Probiotics may support immune function and reduce respiratory infections that can trigger or exacerbate chronic cough.
Avoidance of food triggers that may worsen reflux (caffeine, alcohol, spicy foods, fatty foods) is important when reflux is contributing to cough.
Mind-Body Therapies
Stress and anxiety can exacerbate chronic cough through multiple mechanisms, including increased muscle tension, heightened cough reflex sensitivity, and behaviors such as throat clearing. Mind-body therapies can help address these factors.
Mindfulness meditation and relaxation techniques can reduce the perception of cough and improve coping with chronic symptoms.
Breathing exercises including diaphragmatic breathing and pursed-lip breathing can improve respiratory efficiency and reduce the urge to cough.
Yoga, modified for individual capabilities, can improve overall well-being, reduce stress, and enhance respiratory function.
Biofeedback provides information about physiological processes (such as muscle tension) that can help individuals learn to control these processes and reduce cough triggers.

Lifestyle Modifications and Self-Care
Environmental Modifications
Reducing exposure to environmental irritants can significantly improve chronic cough.
Air quality awareness is important. Monitoring air quality reports and limiting outdoor activities on poor air quality days can reduce exposure to particulate matter and pollutants. In Dubai, this is particularly relevant during sandstorm events.
Indoor air quality can be improved by using HEPA air purifiers, maintaining appropriate humidity (40-50%), avoiding tobacco smoke and strong odors, and ensuring adequate ventilation. Regular cleaning to reduce dust and mold is important.
Allergen avoidance may be beneficial for patients with allergic sensitization. This may include dust mite covers for bedding, pet management strategies, and avoidance of specific allergens identified through testing.
Occupational modifications may be necessary for patients with cough related to workplace exposures. Use of protective equipment and workplace modifications can reduce exposure.
Dietary Modifications
Dietary changes can help manage chronic cough, particularly when reflux is a contributing factor.
Small, frequent meals rather than large meals can reduce reflux by avoiding gastric distension.
Avoiding trigger foods and beverages is important when reflux contributes to cough. Common triggers include caffeine, alcohol, chocolate, mint, fatty foods, spicy foods, and acidic foods (citrus, tomatoes).
Adequate hydration helps keep secretions thin and easier to clear.
Eating dinner earlier (at least 2-3 hours before bedtime) can reduce nocturnal reflux and cough.
Maintaining a healthy weight reduces intra-abdominal pressure and reflux risk.
Vocal Health
For patients with chronic cough related to voice use or laryngeal irritation, vocal health strategies can help.
Hydration of the vocal folds through adequate systemic hydration and humidification of indoor air is important.
Avoiding excessive throat clearing, which can irritate the larynx and perpetuate cough.
Using voice modulation techniques to avoid straining the voice.
Avoiding whispering, which can actually strain the vocal cords more than normal speaking.
Sleep Positioning
Sleep positioning can affect cough, particularly when reflux is involved.
Elevating the head of the bed by 6-8 inches (15-20 cm) can reduce nocturnal reflux and cough.
Sleeping on the left side may reduce reflux compared to sleeping on the right side or back.
Avoiding meals within 2-3 hours of bedtime reduces reflux risk during sleep.

Dubai-Specific Considerations
Environmental Factors in Dubai
Dubai’s unique environment presents specific challenges for individuals with chronic cough.
Sand and dust storms are a characteristic feature of Dubai’s climate and can significantly impact air quality. These events bring high concentrations of particulate matter that can irritate the airways and trigger or worsen cough. Health advisories during dust storms recommend limiting outdoor activities.
Indoor air quality in Dubai is heavily influenced by the extensive use of air conditioning systems. Well-maintained systems with good filters can improve indoor air quality by filtering outdoor pollutants. However, poorly maintained systems can harbor dust mites, mold, and bacteria. Regular filter changes and system cleaning are essential.
The dry climate in Dubai can potentially irritate airways. Using humidifiers to add moisture to indoor air may be beneficial for some individuals.
Healthcare Access
Dubai offers high-quality healthcare facilities with access to specialists including pulmonologists, allergists, and gastroenterologists who commonly manage chronic cough.
Health insurance is mandatory in Dubai, with most plans covering consultations and treatment for chronic cough.
For visitors and tourists, healthcare facilities are available, though costs can be significant without insurance.
Lifestyle in Dubai
The active lifestyle many residents enjoy in Dubai, including outdoor activities during cooler months, may need to be modified during periods of poor air quality.
Smoking regulations in Dubai have become stricter, with smoking banned in many public places. This benefits respiratory health for both smokers and those exposed to secondhand smoke.
The cosmopolitan nature of Dubai means access to diverse culinary traditions, which can be both an opportunity (varied, healthy food options) and a challenge (potential reflux triggers).

Frequently Asked Questions
Understanding Chronic Cough
What is chronic cough? Chronic cough is defined as a cough lasting more than 8 weeks in adults. It is a symptom of underlying disease rather than a diagnosis itself.
Why won’t my cough go away? Chronic cough persists because the underlying cause has not been identified or adequately treated, or because the cough reflex has become hypersensitive. A systematic evaluation is needed to identify the cause.
Is chronic cough serious? While chronic cough is usually not life-threatening, it can significantly impact quality of life and may indicate serious underlying disease. Evaluation is important to exclude concerning causes.
Can stress cause chronic cough? Stress does not directly cause chronic cough but can exacerbate it through increased muscle tension, heightened cough reflex sensitivity, and behaviors like throat clearing.
What is cough hypersensitivity syndrome? Cough hypersensitivity syndrome is a condition characterized by heightened cough reflex sensitivity, causing cough in response to stimuli that would not normally provoke it. It may be a consequence of chronic cough from any cause.
Causes and Diagnosis
What are the most common causes of chronic cough? The three most common causes are upper airway cough syndrome (post-nasal drip), asthma and eosinophilic bronchitis, and gastroesophageal reflux disease. Other causes include ACE inhibitors, chronic bronchitis, and bronchiectasis.
How is chronic cough diagnosed? Diagnosis involves history, physical examination, and targeted testing to identify the underlying cause. This may include chest X-ray, spirometry, allergy testing, sinus imaging, and evaluation for reflux.
Can allergies cause chronic cough? Yes, allergic rhinitis is a common cause of upper airway cough syndrome, resulting in post-nasal drip that triggers cough.

Conclusion
Chronic cough is a common and often challenging condition that can significantly impact quality of life. Understanding the underlying causes and pursuing systematic evaluation are essential for effective management. While the journey to resolution may take time and patience, most patients experience significant improvement with appropriate diagnosis and treatment.
At Healers Clinic Dubai, we are committed to providing comprehensive, personalized care for individuals with chronic cough. Our integrative approach combines evidence-based conventional medicine with complementary therapies to address the full spectrum of your needs. Whether your cough is related to upper airway disease, asthma, reflux, or remains unexplained, our team is here to support your journey toward resolution.
Remember that chronic cough is a symptom, not a diagnosis. With thorough evaluation, targeted treatment, and a comprehensive approach addressing the whole person, relief is achievable. Take the first step today by scheduling a consultation with our chronic cough care specialists.
