What can trigger worsening symptoms in asthma sufferers?

Infection by pathogens can lead to worsening symptoms in asthma sufferers because respiratory infections, such as colds or flu, can trigger inflammation in the airways. This inflammation can increase mucus production, lead to constriction of the bronchial tubes, and cause difficulty in breathing, which can exacerbate the underlying asthma condition. Infections can also heighten sensitivity to allergens and irritants, making it more challenging for individuals with asthma to manage their symptoms.

While excessive exercise can sometimes trigger asthma symptoms in certain individuals, it is not universally a trigger and can even be managed with appropriate precautions. Healthy dietary changes and regular medication generally support better asthma control, rather than worsen symptoms, contributing to improved overall health.
