Which of the following can exacerbate asthma symptoms?

Smoke is known to be a significant irritant and trigger for asthma symptoms. It can cause inflammation and irritation of the airways, leading to increased sensitivity and reactivity. When an individual with asthma is exposed to smoke, whether from cigarettes, wood-burning stoves, or even secondhand smoke, it can exacerbate their condition by constricting airways, increasing mucus production, and worsening overall lung function. Understanding this relationship between smoke and asthma is crucial for effective asthma management and prevention of attacks.

On the other hand, regular exercise may actually help improve lung function and overall health in people with asthma, provided it is done in a controlled manner. Consuming dairy is often debated; while some individuals may believe it increases mucus production, research does not consistently support this as a universal trigger. Drinking water is essential for overall health and hydration and does not exacerbate asthma symptoms.
