An asthma cough is a common symptom of chronic airway inflammation, often presenting as a persistent, dry, or hacking cough that worsens at night or during exercise. This cough is a reflex response to the swelling and heightened sensitivity of the airways. While asthma requires professional management, the associated cough symptom can often be lessened using natural methods. These techniques focus on minimizing triggers and calming the irritated respiratory passages, providing support alongside a prescribed treatment plan.
Understanding the Limits of Natural Relief
Asthma is characterized by inflammation and narrowing of the bronchial tubes, a physiological process that natural remedies alone cannot reverse. Prescribed controller medications, such as inhaled corticosteroids, are formulated to reduce the underlying airway inflammation over time. Natural methods should never replace these doctor-prescribed treatments, which are necessary to prevent long-term lung damage and control the disease. The asthma cough signals deep-seated irritation, unlike a common cold cough which is typically short-lived and accompanied by congestion. An asthma-related cough tends to be chronic and may be the only noticeable symptom, a condition known as cough-variant asthma.
Environmental Triggers and Prevention
Managing the immediate environment is a primary strategy for natural asthma control, focusing on the removal of common triggers that irritate the airways. Dust mites thrive in warm, humid conditions and are a frequent trigger for allergic asthma. You can reduce their population by maintaining indoor humidity between 30% and 50% and washing all bedding weekly in hot water, at least 130°F (55°C).
Using specialized allergen-proof covers on mattresses and pillows creates a physical barrier against dust mites in the bedroom. Air filtration is another important measure, with high-efficiency particulate air (HEPA) filters removing tiny airborne irritants. For central heating and cooling systems, filters with a Minimum Efficiency Reporting Value (MERV) rating of 13 or higher are recommended for capturing fine particles like mold spores, pet dander, and other asthma triggers.
Hydration and Soothing Techniques for Cough Relief
Immediate relief for a persistent cough often comes from moisturizing techniques that calm the throat and airways. Steam inhalation can temporarily soothe irritated upper airways by delivering warm, moist air, which hydrates the nasal passages and throat. Standing in a steamy bathroom after running a hot shower is a safe and effective way to achieve this, or you can use a commercial steam inhaler to avoid the risk of scalding associated with using boiling water.
Drinking warm liquids is an effective way to relax the respiratory tract and thin any mucus that might be contributing to the cough. Herbal teas, broths, and warm water are excellent choices. Honey, a natural demulcent, can coat the throat lining, which helps to reduce the irritation that triggers the coughing reflex. However, honey should never be given to children under the age of one year due to the risk of infant botulism.
Incorporating specific breathing exercises can interrupt a coughing fit. Pursed-lip breathing is a technique that helps keep airways open for longer, allowing for more complete exhalation of trapped air. To perform this, relax your neck and shoulder muscles, inhale slowly through your nose for a count of two, then exhale slowly through pursed lips for a count of four or more, making the exhale at least twice as long as the inhale. This deliberate slowing of the breath helps to release air that can become trapped in the lungs.
Recognizing Signs of Worsening Symptoms
While natural methods can offer comfort, certain signs indicate that the asthma is worsening and requires immediate medical attention. A rapid increase in the frequency or severity of coughing and wheezing is a cause for concern. You should seek emergency care if the cough does not subside after using your quick-relief inhaler as prescribed. Other serious symptoms include severe shortness of breath, difficulty speaking in full sentences, or bluish lips or fingernails. A persistent feeling of chest tightness or pain that does not resolve is also a signal to contact your healthcare provider immediately.
