TED-Ed: How does asthma work? - Christopher E. Gaw

Asthma is a chronic respiratory condition affecting over 300 million people worldwide. It is characterized by symptoms such as wheezing, chest tightness, and shortness of breath, often triggered by factors like smoke, pollen, and stress. Asthma attacks occur when these triggers cause airway muscles to constrict and inflammation to increase, leading to breathing difficulties. Inhalers, containing beta-agonists and corticosteroids, are primary treatments that help manage symptoms and prevent attacks. While the exact causes of asthma remain unknown, genetic and environmental factors are believed to play a role.
