Asthma is a chronic respiratory condition that affects millions worldwide. It involves inflammation and narrowing of the airways, leading to symptoms such as coughing, wheezing, and shortness of breath. This article outlines the main causes, common symptoms, and general management tips.
1. What Is Asthma?
Asthma is a long-term condition in which the airways become inflamed and overly sensitive. This reaction can cause narrowing of the air passages and excess mucus production, making it difficult to breathe.
2. Major Causes of Asthma
– Allergens: Dust mites, pollen, mold, and pet dander may trigger asthma attacks.
– Environmental irritants: Air pollution, smoke, and strong odors may worsen symptoms.
– Respiratory infections: Viral infections may increase airway sensitivity.
– Genetics: Family history may raise the risk.
– Exercise or weather changes: Cold air or intense activity can be triggers.
3. Common Symptoms
– Persistent or nighttime cough
– Shortness of breath
– Wheezing or whistling sounds during breathing
– Chest tightness or pressure
– Symptoms that worsen at night or early morning
4. Risk of Asthma Attacks
Asthma attacks may occur suddenly, with severe shortness of breath and wheezing. Triggers such as pollen, dust, or cold air may cause rapid symptom flare-ups. Severe attacks may require urgent medical care.
5. Daily Management Tips
– Maintain clean indoor air and reduce exposure to allergens
– Avoid smoking and secondhand smoke
– Practice moderate, regular exercise that does not overstrain the lungs
– Eat a balanced diet with fruits and vegetables, which may support lung health
