Bronchitis is uncommon in healthy, young nonsmoking adults. Most of what people call bronchitis is actually the cough associated with a chest cold and doesn’t require antibiotics. Many people with allergies or exercise-induced asthma may have their symptoms triggered by a viral URI. It’s often worse at night, with exercise or exposure to cold air. An inhaler, like albuterol, will help chest tightness, wheezing or shortness of breath.
