Final answer:
An asthma attack is frequently triggered by environmental factors such as pollution, allergens, smoke, cold air, infections, and exercise. Asthma is a chronic condition characterized by inflamed airways, and it is influenced by genetic and environmental factors. Avoiding exposure to triggers can help manage asthma symptoms.
Step-by-step explanation:
An asthma attack is often triggered by environmental factors, such as air pollution, allergens, cigarette smoke, airway infections, cold air, or a sudden change in temperature, and exercise. Asthma is a chronic inflammatory disease of the airways that leads to symptoms such as difficulty breathing, chest tightness, and wheezing. The condition can be exacerbated by a number of triggers, including environmental pollutants, airborne allergens (pollen, mold, pet dander), cold air, viral infections, and physical activity.
People with a genetic predisposition to asthma might experience more frequent and severe attacks. In some urban areas, high concentrations of pollution can create "asthma alleys" where the rates of asthma and related diseases are particularly high.
Managing asthma often involves taking prescribed medications and avoiding known triggers. While the genetic factors contributing to asthma are not within one's control, identifying and minimizing exposure to environmental triggers can help reduce the frequency and severity of asthma attacks.
