Asthma: Which symptom suggests nocturnal asthma activity?

Explanation:
Nighttime coughing signals nocturnal asthma activity. In asthma, airway inflammation and bronchial hyperresponsiveness often worsen during sleep due to circadian influences and nighttime triggers, leading to symptoms like coughing, wheezing, chest tightness, and shortness of breath that wake you. The other options don’t point to night-specific activity: shortness of breath only with exertion suggests activity-triggered symptoms, no nocturnal symptoms means the night is symptom-free, and chest pain with meals is not related to asthma and points to GI or cardiac issues. So, a frequent cough at night is the clearest indicator of nocturnal asthma activity.
