Asthma is a chronic respiratory condition that affects the airways, causing inflammation and narrowing, which leads to difficulty breathing. One of the hallmark symptoms of asthma is the “asthma cough.” This cough is often persistent, especially at night or in the early morning, and may be the primary sign of asthma in some people.
It is typically dry and non-productive, meaning it doesn’t bring up mucus. In other cases, the cough might occur in response to triggers like allergens, cold air, exercise, or respiratory infections.
Signs and Symptoms of Asthma
Asthma symptoms can vary widely from person to person and can range from mild to severe. Common signs and symptoms include:
1. Shortness of Breath: Difficulty breathing, especially during physical activity or at night, is a key symptom. Some people may feel like they can’t catch their breath.
2. Wheezing: A high-pitched whistling sound when exhaling is common in asthma. It occurs due to the narrowing of the airways.
3. Chest Tightness: Many individuals with asthma experience a sensation of tightness or pressure in their chest, which can feel like something is squeezing or heavy.
4. Coughing: As mentioned, persistent coughing, particularly at night or after physical exertion, can be a sign of asthma. It often worsens in response to triggers like allergens or cold air.
5. Increased Mucus Production: Some people with asthma may also experience increased production of mucus, which can make breathing more difficult.
6. Breathing Difficulties: Asthma can make it harder for air to flow in and out of the lungs, leading to a feeling of being out of breath, especially when the condition is not well-controlled.

What Are Triggers of Asthma Cough
Asthma cough can be exacerbated by various triggers. These include:
- Allergens: Pollen, dust mites, mold, pet dander, and cockroach droppings are common allergens that can irritate the airways and trigger asthma symptoms.
- Air Pollution: Smoke, fumes, and other pollutants can worsen asthma symptoms.
- Cold Air: Inhalation of cold, dry air can cause the airways to constrict, leading to coughing and difficulty breathing.
- Exercise: Physical activity, particularly in cold or dry environments, can trigger asthma symptoms, including coughing.
- Respiratory Infections: Colds, flu, and other infections can cause asthma flare-ups, leading to coughing, wheezing, and shortness of breath.
- Strong Emotions: Stress, anxiety, or laughing hard can trigger asthma symptoms in some individuals.
- Certain Medications: Non-selective beta-blockers and some anti-inflammatory drugs may exacerbate asthma symptoms.
Tips to Get Rid of Asthma Cough
While asthma is a chronic condition that may not be entirely cured, there are strategies to manage asthma cough and improve quality of life:
1. Use Your Inhalers as Prescribed
- Quick-Relief Inhalers (e.g., albuterol): These are bronchodilators that provide immediate relief from asthma symptoms by relaxing the muscles around the airways. Use as directed during an asthma attack or when you experience cough or wheezing.
- Long-Term Control Inhalers (e.g., corticosteroids): These help reduce inflammation in the airways over time and prevent asthma flare-ups, including coughing. Use daily as prescribed, even if symptoms are not present.
2. Identify and Avoid Triggers
- Track Triggers: Keep a journal to identify specific triggers (e.g., allergens, cold air, exercise) that worsen your asthma. Avoid these triggers whenever possible.
- Allergen Avoidance: For those with allergic asthma, reducing exposure to common allergens (e.g., dust mites, pollen, pets) can significantly reduce coughing and other symptoms.
3. Maintain Good Indoor Air Quality
- Keep Air Clean: Use air purifiers, especially in areas where you spend a lot of time (e.g., bedroom). Consider using HEPA filters to reduce allergens.
- Humidify the Air: A humidifier can add moisture to the air, which helps soothe irritated airways, but be cautious about mold buildup. Regular cleaning of the humidifier is necessary.
4. Practice Breathing Techniques
- Pursed-Lip Breathing: This technique involves breathing in through your nose and exhaling slowly through pursed lips. It helps maintain airflow through the airways and can reduce wheezing and coughing.
- Diaphragmatic Breathing: Focus on breathing from your diaphragm rather than shallow chest breathing. This can help increase lung capacity and improve airflow.
5. Regular Physical Activity
- While exercise can sometimes trigger asthma symptoms, regular, moderate exercise can actually improve lung function and reduce asthma symptoms over time. Consult with your doctor for recommendations on safe exercises, and always warm up properly.
6. Manage Stress and Anxiety
- Relaxation Techniques: Practices like yoga, meditation, or deep breathing exercises can help manage stress, which in turn can reduce asthma symptoms, including coughing.
- Sleep and Rest: Lack of sleep and stress can exacerbate asthma. Aim for adequate rest and relaxation to improve overall lung health.
7. Medications and Treatments
- Long-Term Control Medication: If you experience frequent coughing, consult your doctor about using long-term control medications, such as inhaled corticosteroids or leukotriene modifiers.
- Rescue Medications: For sudden asthma exacerbations, rescue inhalers or nebulizers with bronchodilators may help open the airways and stop coughing quickly.
- Immunotherapy: For those with allergic asthma, allergy shots or sublingual tablets may help reduce the body’s allergic response, potentially reducing asthma symptoms.
8. Dietary Considerations
- Anti-inflammatory Diet: Certain foods, like those rich in omega-3 fatty acids (e.g., salmon, flaxseeds) and antioxidants (e.g., fruits, vegetables), can help reduce inflammation in the airways. Conversely, try to avoid processed foods, excessive salt, or preservatives, which may trigger asthma symptoms.
- Maintain a Healthy Weight: Being overweight can worsen asthma symptoms, so maintaining a healthy weight through diet and exercise is important for asthma management.
9. Monitor Your Asthma
- Peak Flow Meter: Using a peak flow meter to measure how well air moves out of your lungs can help you monitor your asthma and catch potential flare-ups early. If your peak flow readings drop, take your prescribed medication and consult your doctor.
10. Avoid Smoking and Secondhand Smoke
- Quit Smoking: Smoking damages the lungs and worsens asthma symptoms. If you smoke, seek support to quit.
- Avoid Secondhand Smoke: Exposure to secondhand smoke can also trigger asthma symptoms and cause long-term damage to lung health.
When to Seek Medical Help
If you or someone you know has asthma and experiences:
- Persistent or worsening cough despite medication
- Difficulty breathing or shortness of breath that doesn’t improve with a rescue inhaler
- Wheezing that doesn’t go away
- Increased need for rescue inhaler use
- Bluish lips or face, which may indicate a lack of oxygen
It’s important to seek immediate medical attention. An asthma attack can be life-threatening if not treated promptly.
In conclusion, asthma cough is a common symptom of asthma, and while it may not be fully preventable, effective management strategies can reduce its frequency and severity.
By adhering to prescribed treatments, identifying and avoiding triggers, practicing breathing exercises, and maintaining a healthy lifestyle, most individuals with asthma can live well and minimize the impact of asthma cough on their daily lives.
Always consult your healthcare provider for tailored advice and treatment options.
