Which environmental factor is known to trigger asthma attacks?

Air pollution is recognized as a significant environmental factor that can trigger asthma attacks. Various pollutants, such as particulate matter, nitrogen dioxide, sulfur dioxide, and ozone, can irritate the airways and exacerbate asthma symptoms. Individuals with asthma may experience increased airway inflammation and hyperreactivity when exposed to these pollutants, which can lead to difficulty in breathing and the onset of an asthma attack.

While pollen, low humidity, and cold temperatures can also be contributing factors to asthma exacerbations, air pollution has a broader and more well-documented impact on respiratory health, especially in urban areas where various pollutants are prevalent. Understanding the role of air pollution in asthma management is crucial for patients and caregivers to minimize exposure and implement strategies to prevent exacerbations.
