Learning More About Common Asthma Triggers
Outdoor Air Pollution
Pollution caused by industrial emissions and automobile exhaust can cause an asthma episode. In large cities that have air pollution problems, the number of emergency department visits for asthma episodes goes up when the air quality is poor.
You may find cockroaches any place where food is eaten and crumbs are left behind. Decreasing exposure to cockroaches in the home can help reduce asthma attacks. Remove as many water and food sources as you can, because cockroaches need food and water to survive. Vacuum or sweep these areas at least every 2 to 3 days. You can also use roach traps or gels to decrease the number of cockroaches in your home.
Furry pets may trigger an attack. The simplest solution to this situation is to find another home for the pet. However, some pet owners may be too attached to their pets or unable to locate a safe new home for the animal. Any animal causing an allergic reaction should not be allowed in the bedroom. Pets should be kept outside as much as possible and bathed weekly. People with asthma are not allergic to their pet's fur, so trimming the pet's fur will not help your asthma. Frequent vacuuming will reduce the presence of the allergen. If the room has a hard-surface floor, it should be damp-mopped weekly.
When mold is inhaled, it can cause asthma attacks. Eliminating mold throughout the home can help control asthma attacks. Keep humidity levels between 35 percent and 50 percent. In hot, humid climates, this may require the use of air conditioning and/or dehumidifiers. Fixing water leaks and cleaning up any mold in the home can also help.
Other Asthma Triggers
Strenuous physical exercise; adverse weather conditions, like freezing temperatures, high humidity, and thunderstorms; some foods and food additives; and drugs can trigger asthma episodes. Strong emotional states also can lead to hyperventilation and an asthma episode. People with asthma should learn if these things trigger their episodes and avoid them when possible.
