Asthmatics should be aware of potential triggers for their asthma symptoms and avoid them when possible. Common triggers include dust, smoke, pollen, pet dander, and certain fragrances. Asthmatics should also avoid extreme changes in temperature, cold air, and exercise in cold weather. It is important to avoid exposure to irritants in the home, such as chemical cleaning products, aerosols, and strong fragrances. In addition, stress and anxiety can bring on an asthma attack, so it is important to practice relaxation techniques and get enough sleep. Last but not least, make sure to follow your doctor’s advice and take your medication as prescribed.
