What symptom is NOT typically associated with nocturnal asthma?

Nocturnal asthma is characterized by worsening symptoms during the night, which can be quite distressing for patients. The hallmark symptoms include coughing, shortness of breath, and chest tightness, all of which can worsen when lying down or during the night due to various factors such as airway inflammation and increased exposure to allergens.

In contrast, increased appetite is not a symptom associated with nocturnal asthma. It does not have a direct correlation with the respiratory distress or inflammation associated with asthma episodes. Instead, nocturnal asthma typically leads to symptoms that impair breathing and can disrupt sleep, rather than triggering increased hunger or appetite. Thus, recognizing that increased appetite does not fit within the context of nocturnal asthma symptoms highlights why it is the correct answer in this instance.
