What is a characteristic of nocturnal asthma?

Nocturnal asthma is characterized by symptoms that may worsen during sleep. This phenomenon occurs due to several factors, including changes in hormone levels, increased airway inflammation overnight, and a lying down position that can affect lung function and mucus drainage. Patients often experience increased wheezing, coughing, shortness of breath, and chest tightness during nighttime hours, which can lead to sleep disturbances.

The other options do not accurately describe nocturnal asthma. While some asthma symptoms can be impacted by seasonal changes, nocturnal symptoms are specifically tied to nighttime. Similarly, nocturnal asthma is not restricted to childhood; it can affect individuals of all ages. Symptoms typically do not worsen during the day, as nocturnal asthma specifically refers to nighttime exacerbations. Understanding this characteristic is crucial for effective management and treatment planning for patients who suffer from nighttime symptoms.
