Asthma
Asthma may sound typical, but people may realize it’s more dangerous. It’s a lung disease which is chronic wherein the inflamed airways may become enormously sensitive and swollen. Coughing, breathlessness, tightness of chess, and wheezing are its symptoms. The stimuli like smoke, exercise, pollution of air, pollen, and weather conditions are sometimes the reasons why airways become hypersensitive. In patients, when breathing, the muscles that surround the airways contract and expand rhythmically. The airways become narrower that prevents the air flow into the lungs.
