Asthma is a chronic disease that affects the air passages (bronchi) of the lungs because of hypersensitivity to specific substances. In a person with asthma the small airways in the lung become constricted and more inflamed when exposed to an irritant or trigger factor. As asthma attack can be precipitated by certain trigger factors. Preventive measures for asthma can be very effective to control symptoms of asthma. Read to know more about how to prevent asthma attacks.


Outdoor Prevention


In most cases it is not possible to control all the possible trigger factors but there are certain preventative measures that you can take to limit your exposure to outdoor allergens. Avoid outdoor activities on days when pollen in the air is expected to be high, or when it is dusty. Wear a protective mask when you go out. It helps to filter allergens, and prevents cold air from entering your lungs.


Prevention at Home


Allergens that trigger asthma attack are present not only outdoor but are abundant in your house as well. Measures to control exposure to allergens at home include:

  • Avoid smoking and exposure to smoke at home.
  • Avoid feather pillows and wash your pillows and bed sheets with hot water regularly. 
  • Avoid carpets at home.
  • Avoid handling dusty things such as old books and newspapers.
  • Avoid pets at home.
  • Use HEPA (high efficiency particulate air) filters on vacuums and air purifiers as these are very effective in removing allergens, such as pet dander and pollen.


Preventative Medications


Preventative medications are very important for controlling asthma attacks and other symptoms of asthma. Inhaled and oral corticosteroids, long acting beta2 agonists, cromolyn sodium and nedocromil sodium, anti-leukotriene agents (montelukast, zafirlukast) may be prescribed to prevent and control symptoms of asthma. Your doctor will prescribe medications based on the severity of your symptoms.


Asthma is chronic disease but the symptoms can be controlled very effectively and you can expect to have few, if any, symptoms either during the day or at night if you comply with treatment and take adequate preventive measures.
