Which of the following can exacerbate asthma symptoms?

Strong odors or fumes are known irritants that can exacerbate asthma symptoms. For individuals with asthma, exposure to various airborne irritants can trigger inflammation in the airways, leading to increased symptoms such as wheezing, coughing, shortness of breath, and chest tightness. These irritants can include tobacco smoke, perfumes, cleaning products, and other strong scents that can provoke a respiratory response.

In contrast, regular exercise is generally beneficial for individuals with asthma, as it helps to improve lung function and overall fitness, provided it is done in a controlled environment where triggers are minimized. Consumption of fruits typically supports overall health and is associated with positive effects on respiratory function due to their antioxidant properties. Exposure to sunlight, while it can affect some aspects of health, is not directly linked to asthma exacerbation and is often considered beneficial. Therefore, strong odors or fumes stand out as a clear trigger for worsening asthma symptoms.
