Why asthma can hit you harder as an adult?
A: The reason adults develop asthma isn't always clear. Respiratory infections, allergies and airway irritants , such as smoke and mold, can be triggers. Asthma inflames the airways, triggering excess mucus production and smooth muscle spasms. This narrows the airways, causing symptoms such as: Chest tightness or pressure. Difficulty breathing.
