Asthma can be triggered by various factors, some of which may surprise you. Common risk factors include genetic predisposition, environmental pollutants, and lifestyle choices. For instance, if one or both of your parents have asthma, you are more likely to develop it. Environmental factors such as air pollution, cigarette smoke, and allergens like dust mites, pet dander, and mold can also trigger asthma attacks. Interestingly, indoor air pollution from gas stoves and household cleaners can contribute to asthma symptoms. Weather changes, such as cold air and high humidity, can also cause asthma attacks. Additionally, being overweight and exposure to secondhand smoke are significant risk factors. Other health conditions like eczema and allergic rhinitis are often linked to asthma. Understanding these risk factors can help you take preventive measures to manage or avoid asthma symptoms.
