For asthmatics, one effective prevention method is to identify specific attack triggers, such as pollen or cold air, and avoid those irritants whenever possible, states Mayo Clinic. At home, asthmatics should limit decor that collects dust, such as carpet, and keep mattresses and pillows encased in dust-proof covers.
Routine dusting and air-quality control reduce triggers in the home, but asthmatics should wear a mask when cleaning potential irritants, according to Mayo Clinic. A dehumidifier can help remove excess moisture in the air for people living in damp climates, while installing air conditioning decreases humidity and allows fewer airborne particles from pollen and weeds into the house. Regularly cleaning rooms that are susceptible to dampness, such as bathrooms, prevents the growth of harmful mold. Covering the mouth and nose is also beneficial when traveling outdoors in cold weather.
When necessary, doctors prescribe controller medications, such as corticosteroids, which the patient takes daily to prevent asthma attacks, explains the American Academy of Asthma, Allergy & Immunology. Rescue medications, such as inhalers, may help relax the airways to quickly relieve early symptoms of an attack, and doctors recommend using them before physical activity for attack prevention.
For long-term health maintenance, asthmatics should regulate their breathing to identify warning signs of an attack and learn to respond effectively, notes Mayo Clinic. Staying up to date on vaccinations, exercising regularly and maintaining a healthy weight also help asthmatics strengthen their lungs.
