Causes of an Asthma Attack

Environmental triggers, such as dust mites, tobacco smoke can cause an attack.  Some of these triggers are listed in the box below. 

Asthma Triggers

Tobacco Smoke

This is also known as Secondhand or Side stream smoke.  All people who have relatives or close friends with asthma should try to stop smoking.  If this can't be accomplished it is critical to smoke only outdoors and not in the home or family car.  Others should not be allowed to smoke in the home, and the asthma sufferer's school or work place should be smoke-free.

Dust Mites

Mattress covers and pillow case covers provide a good barrier between dust mites and the asthma sufferer.  Down-filled pillows, quilts or comforters should not be used and stuffed animals and clutter should be removed from bedrooms. 

Outdoor Air Pollution

Pollution caused by factory and automobile emissions can trigger and asthma attack.  In cities with air pollution problems the number of emergency department visits for asthma attacks rises when the air quality is very poor.

Cockroach Allergen

Asthma attacks can also be reduced by decreasing exposure to cockroaches.  Cockroaches can be found any place food is eaten or prepared.  Remove as many water and food sources as possible because these insects require food and water to survive. Be certain to vacuum or sweep areas where cockroaches are found at least every 2-3 days.  Use roach traps or gels to decrease the number of cockroaches in the home. 

Pets

Pets are a common asthma trigger.  The easiest solution to this problem is to find another home for the pet.  However, pet owners are often too attached to their animals or unable to find a suitable home for the animal.  Any animal causing an allergic reaction should not be allowed in the bedroom.  They should remain outdoors as much as possible and bathed weekly.  Asthma is not triggered by the animal's coat itself so buying a short haired animal or trimming a long haired one will be no help.  Frequent vacuuming will reduce the presence of the allergen and all hard surfaced floors should be damp mopped weekly.

Mold

When mold spores are inhaled they can cause an asthma attack.  Eliminating mold within the home can help control asthma attacks.  Humidity levels should be kept between 35 and 50%.  In hot, humid conditions this may require the use of an air conditioner or dehumidifier.  Repairing water leaks and removing any mold in the home will also help.

Other Triggers

Strenuous exercise; adverse weather conditions like freezing temperatures, high humidity, and thunderstorms; some food and food additives and drugs can lead to an asthma attack.  Strong emotional states can lead to hyperventilation and an asthma episode.  Those suffering from asthma should learn what triggers their episodes and avoid these triggers when at all possible.
