Duration can vary!: Good morning, the surface lining of our airway protects us from the effects of environments and agents we are constantly exposed to. An infection by a virus can destroy this layer, exposing the underlying nerves, which sends signals to contract and reduce the airflow, causing cough and wheezing, especially in those with asthma. Exercise can reduce airway tone, along with inhaled medications.
