Asthma is a chronic respiratory condition in which the airways become inflamed and narrowed, making it difficult to breathe. It is commonly triggered by allergens, pollution, cold air, stress, exercise, or respiratory infections. People with asthma often experience breathlessness, chest tightness, wheezing, and a persistent dry cough. Asthma attacks can range from mild to severe, but with proper treatment, breathing exercises, and lifestyle management, it can be effectively controlled and quality of life can be improved.
