In some individuals chest the inflammation causes chest tightness and breathing problems are experienced especially at night or in the morning. Others only experience the symptoms only during exercise. However hyper responsiveness arises from specifics triggers.
These triggers may include: tobacco smoke, infections such as cold, pneumonia and flu, exercise air pollution, drugs, stress etc. And the symptoms include: shortness of breath wheezing, excessive coughing or cough that keeps one awake at night and the ones mentioned above.
